			<content:encoded><![CDATA[<p>One of the biggest challenges in global multi-center clinical trials (after enrollment of patients) is collaboration between multi-center clinical trial teams: CRAs, investigators, regulatory, marketing, manufacturing, market research, data managers, statisticians and site administrators.</p>
<p>In a complex global environment, pharma do not have control of computer platforms that local sites use &#8211; yet there is an expectation that file and information sharing should be easy yet there are three areas where current systems break down:</p>
<p>1. People forget what files had been shared and with whom they have been shared</p>
<p>2. People have difficulty sharing files with colleagues in a way that is accessible to everyone &#8211; firewalls, VPNs, enterprise content management, DRM, corporate data security policy, end point security, file size &#8211; these are all daunting challenges when all you want to do is share a file with a colleague in Berlin when you are working in a hospital in Washington.</p>
<p>3. Notifications &#8211; how do you know when new information has been added or updated? Not having timely notifications on updates can be a big source of frustration resulting in team members pinging other members over and over again with emails.</p>
<p>Over the past 10 years a generation of complex enterprise content management software systems have grown up &#8211; they are bloated, expensive, difficult to implement, not available to the entire multi-center team and in many cases written by English speaking software vendors who cannot conceive that there are people in the world who feel more comfortable communicating in their native tongue of French, German, Hebrew or Finnish!</p>
<p>We are developing (currently in beta with a Tier 1 bio-pharma in EMEA)  a Web-based, agile collaboration system with a light-weight, easy to use, simple architecture, that saves time and reduces IT and travel costs – and literally gets everyone on the same page.</p>
<p>The system resolves the 3 breakdowns above while recording all user activities in a detailed audit trail in order to meet internal control and FDA regulatory requirements.</p>
<p>The system also provides significant cost benefits in addition to improving information collaboration:</p>
<p>•	Reduces travel costs: Using online events, integrated media and file sharing and discussions, the clinical trial team and investigators can conduct program reviews, education activities and special events.</p>
<p>•	Eliminates proprietary IT: No proprietary software or hardware and no IT integration. No extra investments in information technologies, CRM, sales force integration and data mining.</p>
<p>If this interests you &#8211; drop me a line!</p>

			<content:encoded><![CDATA[<p>My colleague, <a title="Michel Godet Consulting" href="http://www.michelgodet.com/" target="_blank">Michel Godet</a> &#8211; sent me a link to an article that Mike Rothman recently wrote.</p>
<p>Michel  (rightly) thinks that it supports the approach that we have been pushing in Europe for over a year now, to justify data security technology investments by using Value at Risk calculations.</p>
<p>Mike&#8217;s article &#8211; <a title="Building a business case for data security" href="http://searchsecurity.techtarget.com/expert/KnowledgebaseAnswer/0,289625,sid14_gci1333725,00.html " target="_blank">building a business case for security</a> is good. I agree with most of what he writes (I would have commented but searchsecurity doesn&#8217;t allow commenting on their <em>Ask The Security Expert: Questions &amp; Answers </em>articles.</p>
<p>So &#8211; I will use my own blog to post a couple of my comments (I should probably ping Mogull on this too but I lost  his email)</p>
<p>1) I agree that if you can&#8217;t get past the first energy barrier of concern with information protection than you are a non-starter for DLP ( or any data security technology for that matter &#8211; it must fit the business needs &#8211; otherwise it&#8217;s like trying to sell a trombone to a violinist.  Total waste of time</p>
<p>However &#8211; once you get past the first road block, the business problem for security investment is:</p>
<blockquote><p>What is your value at risk, what are the right security countermeasures and are they cost-effective.? Not &#8211; what are the vendors selling this quarter.</p></blockquote>
<p>There is no reason in the world why data security should be any different than any other IT investment.</p>
<p>2) I totally disagree that looking only at a network-based DLP product is inherently limiting. Just because a few vendors like Websense and Symantec, have integrated end point and gateway products doesn&#8217;t  makes them cost-effective data security countermeasures, ensure success of the project or prevent the next data breach.</p>
<p>Let me submit  two counter-examples:</p>
<p>A) Suppose all your sensitive data is in the cloud &#8211; then maybe network DLP <strong>is</strong> a good fit</p>
<p>B) Suppose all your endpoints are in the cloud &#8211; then maybe endpoint DLP is a good fit</p>
<p>C) Suppose all your sensitive data is on notebooks &#8211; then maybe encryption is the right countermeasure to data loss.</p>
<p>The answer is that you have to measure stuff &#8211; measure your people, process and system vulnerabilities and where your assets are headed. After that you need to estimate your  VaR and only THEN start thinking about the people, process and technology countermeasures</p>
<p>BTW &#8211; I&#8217;ve been saying this for years</p>
<p>October 28, 2004 &#8211;  <span style="color: #000000;"><a title="A guide to buying DLP" href="http://www.computerworld.com/s/article/96934/Part_4_A_guide_to_buying_extrusion_prevention_products " target="_blank">A guide to buying extrusion prevention products</a></span></p>
<p><span style="color: #000000;"><a title="A guide to buying DLP" href="http://www.computerworld.com/s/article/96934/Part_4_A_guide_to_buying_extrusion_prevention_products " target="_blank"></a>March 17, 2005 - <span style="color: #000000;"><a title="How to justify information security spending" href="http://www.computerworld.com/s/article/100413/How_to_justify_information_security_spending" target="_blank">How to justify Information security spending</a></span></span></p>
<p><span style="color: #000000;"><span style="color: #000000;">Now if only we could find a way to monetize being right.</span></span></p>

			<content:encoded><![CDATA[<p>The new Israeli administration has invited Microsoft to head a government IT steering comittee &#8211; the item caused a bit of a ruckus in the Israeli Open Source community a few months ago &#8211; although I personally feel that as the world&#8217;s largest software vendor &#8211; they have a lot to contribute.</p>
<p>Now I think we have reached a new level of Microsoft sycophancy with the Obama administration implementing a Bush decision to standardize IT but in a way that makes practically no sense at all &#8211; let&#8217;s ban all non IE browsers.  It&#8217;s really scary to what lengths the Obama administration will go undo Bush policy.</p>
<blockquote><p>In keeping with the requirements of the Federal Desktop Core Configuration, all third-party browsers will be removed from customer workstations beginning Tuesday, Aug.18. Internet Explorer is the standard browser and will be maintained. Netscape, Google Chrome and Firefox will be removed.&#8221;</p></blockquote>
<p>It does make sense to standardize on a browser &#8211; but why standardize on the most vulnerable browser and operating system?  Why not standardize on Ubuntu and FF 3 on the desktop or standardize on diskless workstations with Citrix or TightVNC?</p>

<p>The buzzword du-jour in the current economic crash of 2008 is &#8220;Cloud Computing&#8221;.</p>
<p>There are several interesting question around cloud computing &#8211; why now, how are people building it, what are people doing with it and what about security.</p>
<p>1) Why now?</p>
<p>Back in 2001 after the dot com crash, On-demand / SaaS started picking up. My personal  explanation is that  a) there were a lot of  programmers and entrepeneurs out of work, looking for new things to do and  b) an oversupply of bandwidth and server capacity on the Internet and c) a lot of VCs looking for the next big thing. The sales guys try to pitch an economic reason for on-demand: businesses not having the money to buy large enterprise software systems in a down-market.  Since Salesforce.com is not keeping up with the profitability of year-on-year growth of Oracle Applications and SAP &#8211; I don&#8217;t buy it. At $50/seat for Salesforce.com &#8211; if I have 100 people, it&#8217;s $5000/month or $60,000/year which is 10x more than I would pay for a free open source instance of SugarCRM or TigerCRM running on a dedicated server at rackspace.com. If SaaS is not an economically sustainable business model for service providers, it will not sustain  for end user customers either long term.</p>
<p><span id="more-922"></span></p>
<p>2) How are people building cloud computing services?<br />
<strong>The drivers and emotions are similar</strong> (just like in 2001, cloud computing vendors are hyping the economic crash as a reason to buy their wares). In 2008, we have additional drivers &#8211; server virtualization and improved cluster management.</p>
<p>3) What can you do with it?<br />
<strong>Thanks to  free open source</strong> &#8211; it&#8217;s pretty easy to install, use, customize and develop Web applications in the cloud. Unlike 2001, there are now a lot of very good free open source  line of business applications that run on shared infrastructure that are all based on PHP, MySQL, Postgresql, Python etc. Note that you cannot  take J2EE or .NET applications and run them on dreamhost.com, slicehost.com, Amazon or Google App Engine.</p>
<p><strong>Extending the cloud on the net. </strong>One of the coolest things happening right now, I think is sharing, correlating and interacting between local Web application instances and public Web services. There are of course tons of examples &#8211; like blogs and RSS Feeds but it&#8217;s beginning to get interesting with applications like SugarCRM tapping into services like Jigsaw (which is a professional sales lead network).  The idea is that you can run SugarCRM on your local server instance and tap into a big professional network like JigSaw.</p>
<p>4) Security in the cloud</p>
<p>Predictably this is a hot issue &#8211; (I just googled for &#8220;Security in  cloud computing&#8221; and got 14.9 million hits)  starting with <a title="Cloud computing securiyt" href="http://cloudsecurity.org/" target="_blank">Cloud security.org</a>.  There is understandably a lot of concern for security of data in a computing resource that is outside your organizational network and concern for availability of the service.  This area deserves a lot more than a 30,000 foot answer, but I would try and break this down into three areas &#8211; confidentiality, integrity and availability</p>
<ol>
<li><strong>Confidentiality</strong> &#8211; Data security in the cloud is, based on my personal experience, arguably better than in an IT enterprise network.   The people that run a cloud utility at Amazon, Google App engine, slicehost or Mosso &#8211; do this for a living and definitely have more expertise than 99% of IT departments in the world.   Not having the servers on your network means that malicious insiders or outsiders do not have an easily accessible target. From a security perspective &#8211; the attack surface is  smaller but the threats are totally the same.</li>
<li><strong>Integrity </strong>- Data integrity has more to do with software implementation bugs or basic design flaws then with the availability of the cloud computing utility.   We will still need good software security design, implementation and excellent security assessment.</li>
<li><strong>Availability </strong>- This is an area  where Amazon EC2 and Google App Engine took hits a few months ago but I believe that by comparison &#8211; the reliability and availability of a services like EC2, Google App Engine and Mosso are better than electrical utilities or cell phone networks which serve billions of users.  So &#8211; IMHO &#8211; the future for high availability in the cloud is rosy.</li>
</ol>

<p dir="ltr"><span id="more-839"></span></p>
<p>With the announcement of Atmos today, EMC has also created a new acronym Cloud Optimized Storage (COS).  Think of COS in terms of the evolution of three storage system acronyms over the last ten years.</p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><em><span style="font-family: Times New Roman;">SAN -&gt;  NAS -&gt;  CAS -&gt; <strong><span style="text-decoration: underline;">COS</span></strong>.</span></em></p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;">What follows is a brief description of this evolution in terms of value to the customer: </span></p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><strong><span style="font-family: Times New Roman;">SAN Value = Centralized, secure multi-tenancy for blocks.</span></strong></p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><strong><span style="font-family: Times New Roman;">NAS Value = Centralized, secure multi-tenancy for files.</span></strong></p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><strong><span style="font-family: Times New Roman;">CAS Value = Centralized, secure multi-tenancy for objects (content + metadata).</span></strong></p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><strong><span style="font-family: Times New Roman;">COS Value = <em><span style="text-decoration: underline;">Globalized</span></em>, secure multi-tenancy for content with <em><span style="text-decoration: underline;">rich policies</span></em>.</span></strong></p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;">In my mind the two distinguishing values that Cloud Optimized Storage adds to the party are summarized by using the words &#8220;Globalized&#8221; and &#8220;rich policies&#8221;.</span></p>
<ul type="disc">
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">COS implies that the storage is <em><span style="text-decoration: underline;">globally</span></em> accessible. The conventional understanding behind SAN, NAS, and CAS systems was that they were &#8220;frames&#8221; or &#8220;racks&#8221; that lived within the walls of a data center.  Cloud optimized storage systems are <span style="text-decoration: underline;">geographically disperse yet managed as a single entity</span>. </span></li>
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">COS also implies that <em><span style="text-decoration: underline;">rich metadata</span></em> glues everything together. Centera introduced the option of appending metadata to content; COS introduces the imperative of attaching <em><span style="text-decoration: underline;">policies</span></em> to content. </span></li>
</ul>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;"><strong>The Special Sauce of COS</strong><br />
Rich metadata in the form of policies is the special sauce behind Atmos and is the <em>reason </em>for the creation of a new class of storage system.  Atmos contains five &#8220;built-in&#8221; policies that can be attached to content:</span></p>
<ul type="disc">
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">Replication </span></li>
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">Compression </span></li>
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">Spin-down </span></li>
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">Object de-dup </span></li>
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">Versioning </span></li>
</ul>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;">When any of these policies are attached to Atmos, COS techniques are used to automatically move the content around the globe to the locations that provide those services. Customers can place content into Atmos (using REST/SOAP or CIFS/NFS/IFS) and then associate that content with one of the built-in policies. The Atmos architecture also allows for extensible policies. Customers that want to specify policies outside of those natively offered by Atmos can develop their own.  For example, picture a customer that wants to add &#8220;Cheap Power&#8221; as a policy; Atmos can be programmed to globally move content to a location with the cheapest power rates.</span></p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr">
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;"><strong>Let&#8217;s Stop Here</strong><br />
When it comes to how the Atmos software has been built, there&#8217;s much more to say. I&#8217;ll be back with more detail about how this thing has been built. I&#8217;ll also do some comparative analysis of COS against conventional SAN/NAS/CAS technologies. Covering these items in this post, however, would take away the emphasis from this straightforward definition of COS:</span></p>
<p style="margin: 18pt 0cm 0pt; background: white none repeat scroll 0% 0%; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;">Cloud Optimized Storage: <em>global </em>storage with a <em>policy</em> focus.<br />
EMC Atmos is EMC&#8217;s first Cloud Optimised Storage offering designed for policy based information storage, information distribution and information retrieval at a global scale. GA code shipped at the end of June and customers and partners have been deploying Atmos repositories in their own environments since the second half of 08.<br />
While some competitors were flapping their gums and asking whatever crazy questions came into their heads EMC was shipping a product whose team didn&#8217;t miss a single milestone and met their ship date. Now that the marketing machine has spun up and the EMC Sales sledgehammer is about to drive those competitors into the ground I&#8217;ll be following their backtracking with some enthusiasm. </span>
</p>
<p style="margin: 0cm 0cm 0pt; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;"><strong>So what is EMC Atmos?</strong> What Atmos <span style="text-decoration: underline;">isn&#8217;t</span> is a clustered file system or a warmed over NAS offering clustered or otherwise. Atmos(phere) was designed by the Cloud Infrastructure and Services Division (CISD) from the ground up with a number of distinct characteristics. </span></p>
<ul type="disc">
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">Information inside the Atmos repository is stored as objects. <strong>Policies</strong> can be created to act on those objects and this is a key differentiator as it allows Atmos to apply different functionality and different service levels to different types of users and their data. Managing information, which is what we should be doing, as opposed to wrangling blocks and file systems as we tend to do. </span></li>
</ul>
<ul type="disc">
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">There is no concept of GBs or TBs to EMC Atmos, those units of storage capacity are too small, Atmos is designed for multi-Petabyte deployments. There are no LUNs. There is no RAID. There are only <strong>objects</strong> and <strong>metadata</strong>. </span></li>
</ul>
<ul type="disc">
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">There is a <strong>unified namespace</strong>. Atmos operates not on individual information silos but as a single repository regardless of how many Petabytes containing how many billions of objects are in use spread across whatever number of locations available to who knows how many users. </span></li>
</ul>
<ul type="disc">
<li style="margin: 0cm 0cm 0pt 36pt; direction: ltr; text-align: left;" dir="ltr"> <span style="font-family: Times New Roman;">There is a <strong>single management console</strong> for management regardless of how many locations the object repository is distributed across. This global scale approach means that Atmos had to be an <strong>autonomic system</strong>. Automatically reacting to environmental and workload changes as well as failures to ensure global availability. </span></li>
</ul>
<p dir="ltr"><span style="font-family: Times New Roman;">What those traits should highlight for you is that Atmos isn&#8217;t a SAN offering isn&#8217;t a NAS offering and neither is it a CAS offering. It&#8217;s a COS offering, cloud optimised storage, with web services such as SOAP and REST for access.</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;"><br />
There&#8217;s a lot of info on Atmos on the various blogs and up on </span><a href="http://www.emc.com/collateral/demos/microsites/mediaplayer-video/atmos-to-the-point.htm" target="_blank"><span style="color: #000000;"><span style="font-family: Times New Roman;">EMC.com</span></span></a><span style="font-family: Times New Roman;"> but this entry is about &#8220;Building EMC Atmos&#8221; and for that information I went to one of the Atmos architects. Dr. Patrick Eaton. Patrick Eaton received his PhD from Berkeley and was one of the primary members of Professor John Kubiatowicz OceanStore project. As I learned from speaking to him he&#8217;s been thinking about stuff like this for a number of years and if he wasn&#8217;t building globally distributed storage systems he&#8217;d be indulging his passion for music working in the field of digital sound for a company like Yamaha or Korg.</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">With a tinge of regret he tells me that these days he&#8217;s more of a consumer than a creator of music but as he&#8217;s been busy building something new from the ground up that&#8217;s understandable.<br />
In person he&#8217;s taller and younger than I had expected, he smiles easily and comes across as an open personality. Clearly not one of these academic types who had their sense of humour surgically removed before they submitted their thesis.<br />
As I was to learn Atmos started with five people out at the EMC Cambridge facility working on it&#8217;s floor to ceiling whiteboards looking to solve a problem.<br />
&#8220;Fundamentally this was a distributed systems problem. How do you take a loose collection of services distributed across a wide area and make them operate as you want them to operate?&#8221;<br />
Fortunately for me this isn&#8217;t a question I have to answer or I&#8217;d need more than the floor to ceiling whiteboards but he pauses for a split second before moving on.</span>
</p>
<p dir="ltr"><span style="font-family: Times New Roman;">&#8220;EMC is really good at selling high end storage to really high end people. If you can drop tens of dollars per GB on a storage system man does EMC have offerings for you but data growth is continuing to explode and not everybody has data which justifies that level of expenditure or has the financial resources to justify spending that much money on storage. So, EMC was coming across a customer segment for whom they didn&#8217;t have an offering and the goal for Atmos was to provide a low cost bulk storage system for these emerging markets, like Web 2.0 companies or other industries with lots of user generated content. </span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">Yes you can put that stuff on regular SAN or NAS systems and that&#8217;s what customers have been doing as the only other option was to start writing and maintaining their own storage software and build their own storage hardware. That&#8217;s far from ideal as the value of these companies is in their applications and the services those applications provide. </span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">What we needed to do was provide a Terrabyte at something like ten or more times cheaper than existing SAN or NAS storage systems can offer. That is the problem Atmos was designed to solve and a key part of the product vision comes from the policy driven features of Atmos.<br />
Yes you&#8217;re targeting the bulk storage market, the TME and Web 2.0 spaces with those mountains of user generated content, but people want to use that storage in very different ways.<br />
Some people want to have one data centre, some want two others want many more.<br />
Some need to support different types of workloads, various types of object sizes, control where they locate specific objects and how they get them close to their customer regardless of where on the planet the customer is located in relation to where the data was first stored</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">At the core of the Atmos design is how we allow customers to define policies as to how data actually hits disk. There are no administrators saying &#8220;Joe&#8217;s photos should be on this particular piece of spinning rust&#8221;, rather they write policies to describe how Joe is a subscription customer therefore his files require a certain number of copies associated with them for backup and should have a certain rolling retention policy in case he cancels his account. Thus they should be in this data centre here and not in one thousands of miles away.<br />
But if Joe packs up the family and the dog and moves across country his data may be replicated to the data centre now closest to him depending on the policies applied to his files.</span>
</p>
<p dir="ltr"><span style="font-family: Times New Roman;">Information management is something EMC talks about a lot so providing a storage solution designed with policy based information management at it&#8217;s core is a big thing we wanted to do with Atmos. You&#8217;re not just storing information, you&#8217;re replicating it to where it&#8217;s needed and putting it as close to the user as possible. You&#8217;re compressing it, de-duplicating it or deleting it depending on what policies are applied to it and if it hasn&#8217;t been accessed in a while you can even spin down the drives inactive objects are stored on to save power.</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">Multi-tenancy, could we talk about that a bit more? Could I offer storage as a service to different users or organisations?<br />
&#8220;Yes you could. Multi-tenancy means that Atmos can support many different tenants with logical isolation. Each tenant can have their own private namespace under the Atmos namespace but tenants are not aware of other tenants or the objects belonging to those tenants. </span>
</p>
<p dir="ltr"><span style="font-family: Times New Roman;">You could be providing services to users out on the Internet and hosting application test and dev as well as providing services to your internal business units, but none of those tenants would know about each other.&#8221;</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">We were talking about this being a low cost solution, what&#8217;s low cost at the scale we are talking about here? Sure there&#8217;s capacity cost but it&#8217;s not just that..<br />
&#8220;Well not only does the initial cost of delivering the product to the doorstep have to be low but also it has to be something that the customer can maintain very easily and we&#8217;re talking about the Petabyte range when we&#8217;re talking about deploying this so one of the key design elements was how to provide a customer installable configurable and maintainable implementation. </span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">Going back to the traditional EMC model of &#8220;We&#8217;ll make sure it works but you&#8217;re going to pay for it&#8221;, where parts show up at your door with a service engineer attached well that shoots the entire low cost target out of the water if you have to do that more than a few times a year.<br />
That&#8217;s why a lot of the installation, configuration and maintenance can be done by the customer themselves.</span>
</p>
<p dir="ltr"><span style="font-family: Times New Roman;">Low cost, low touch, incredible scale and density. Billions of objects globally distributed with policy based information management. Petabytes of storage which could be in the same room or distributed around the world but with a single point of management. Those were some of the design goals.&#8221; </span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">Okay so you&#8217;ve built and shipped Atmos, we&#8217;re were talking about having this pre-announcement chat back when you were just about to head off on holiday this past summer right after the code went GA, so what have you learned from building a product as opposed to working on a project?</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">&#8220;I learned a lot about managing cross continent teams. Maybe 50% of our developers and 80% of our QA is split between Beijing and Shanghai China. That&#8217;s a 12 hour difference which can be challenging since there&#8217;s no overlap during the day and there are cultural communication differences to factor in.</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">When the group was smaller I was exposed more to customer interactions and it was always interesting to get feedback and find out how they plan on using Atmos as opposed to how you think they&#8217;ll use it. Now it&#8217;s up and running in their environments I get a different kind of feedback as I&#8217;m watching how they&#8217;re actually using the product in production.</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">I was also blessed to join this group when there were five of us. I&#8217;ve been able to grow with the group and assume some responsibility and some leadership which has stretched me and it&#8217;s a stretching that a lot of freshly minted PhDs don&#8217;t get so early on in their career. It was pretty natural when there was five people here and maybe ten over there that I could take well defined pieces of the system and then lead them through implementation. Now that we&#8217;ve grown to over a hundred people you can&#8217;t take the people who&#8217;ve been there the longest and have them doing that.<br />
I&#8217;ve been really blessed that way and really fortunate to have been able to join an organization in it&#8217;s infancy and be able to grow with the organization. The opportunity here has really been amazing.&#8221;</span>
</p>
<p dir="ltr"><span style="font-family: Times New Roman;">You moved from California to Massachusetts to join EMC and build Atmos from the ground up how did the move to the east coast turn out for you?</span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">&#8220;We love it here. My wife and I are from the mid-west, which does have winters, so the seasons have made a welcome return. California has beautiful weather but it can start to feel like Groundhog Day while here the seasons are refreshing. The city is nice and I tell my manager all the time that we need to recruit more in California as there&#8217;s not a whole lot of places you can draw from in the US and with a straight face tell them that Boston has more affordable houses and better commutes. </span></p>
<p dir="ltr"><span style="font-family: Times New Roman;">Californians you can say that to and it&#8217;s true.&#8221;</span></p>

<p style="margin: 0cm 0cm 0pt; background: white none repeat scroll 0% 0%; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;">I feel drawn to post on the details of Atmos and give my opinion whether it is good, bad, innovative or not. However there&#8217;s one small problem. Normally I comment on things that I&#8217;ve touched &#8211; installed/used/configured/broken etc, but Atmos doesn&#8217;t fit this model so my comments are based on the marketing information EMC have provided to date. Unfortunately the devil is in the detail and without the ability to &#8220;kick the tyres&#8221;, so to speak, my opinions can only be limited and somewhat biased by the information I have. Nevertheless, let&#8217;s have a go.</span></p>
<p><strong>Hardware</strong><br />
From a hardware perspective, there&#8217;s nothing radical here. Drives are all SATA-II 7.2K 1TB capacity. This is the same as the much maligned IBM/XIV Nextra, which also only offers one drive size (I seem to remember EMC a while back picking this up as an issue with XIV). In terms of density, the highest configuration (WS1-360) offers 360 drives in a single 44U rack. Compare this with Copan which provides up to 896 drives maximum (although you&#8217;re not restricted to this size).</p>

What is the storage overhead of that deployment?</span></p>

<p style="margin: 0cm 0cm 12pt; background: white none repeat scroll 0% 0%; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;">So, does that mean Atmos is relying on replication of data to another node as a replacement for hardware protection? I would feel mighty uncomfortable to think I needed to wait for data to replicate before I had some form of hardware-based redundancy &#8211; even XIV has that.<br />
Worse still, do I need to buy at least 2 arrays to guarantee data protection?</span></p>
<p>Front-end connectivity is all IP based, which presumably includes replication too, although there are no details of replication port counts or even IP port counts, other than the indication of 10Gb availability, if required.</p>
<p>One feature quoted on all the literature is Spin Down. Presumably this means spinning down drives to reduce power consumption; but spin down depends on data layout. There are two issues; if you&#8217;ve designed your system for performance, data from a single file may be spread across many spindles. How do you spin down drives when they all potentially contain active data? If you&#8217;ve laid out data on single drives, then you need to move all the inactive data to specific spindles to spin them down &#8211; that means putting the active data on a smaller number of spindles &#8211; impacting performance and redundancy in the case of a disk failure. The way in which Atmos does its data layout is <a href="http://thestorageanarchist.typepad.com/weblog/2008/09/1025-something.html" target="_blank"><span style="color: #000000;"><span style="font-family: Times New Roman;">something you should know</span></span></a><span style="font-family: Times New Roman;"> &#8211; because if Barry is right, then his XIV issue could equally apply to Atmos too.</span></p>
<p>So to summarise, there&#8217;s nothing radical in the hardware at all. It&#8217;s all commodity-type hardware &#8211; just big quantities of storage. Obviously this is by design and perhaps it&#8217;s a good thing as unstructured data doesn&#8217;t need performance. Certainly as quoted by &#8216;zilla, the aim was to provide large volumes of low cost storage and compared to the competition, Atmos does an average job of that.</p>
<p><strong>Software</strong><br />
This is where things get more interesting and to be fair, the EMC message is that this is a software play. Here are some of the highlights;</p>
<p><em>Unified Namespace</em><br />
To quote &#8216;zilla again:<br />
&#8220;There is a unified namespace. Atmos operates not on individual information silos but as a single repository <strong>regardless</strong> of how many Petabytes containing how many <strong>billions</strong> of objects are in use spread across <strong>whatever</strong> number of locations available to who knows how many users.&#8221;</p>
<p>I&#8217;ve highlighted a few words here because I think this quote is interesting; the implication is that there is no impact on the volume of data or its geographical dispersion.<br />
If that&#8217;s the case (a) how big is this metadata repository (b) how can I replicate it (c) how can I trust that it is concurrent and accurate in each location.</p>
<p>I agree that a unified name space is essential, however there are already plenty of implementations of this technology out there, so what&#8217;s new with the Atmos version? I would want to really test the premise that EMC can provide a concurrent, consistent name space across the globe without significant performance or capacity impact.</p>
<p><em>Metadata &amp; Policies</em><br />
It is true that the major hassle with unstructured data is the ability to manage it using metadata based policies and this feature of Atmos is a <em>good thing</em>. What&#8217;s not clear to me is where this metadata comes from. I can get plenty of metadata today from my unstructured data; file name, file type, size, creation date, last accessed, file extension and so on. There are plenty of products on the market today which can apply rules and policies based on this metadata, however to do anything <em>useful</em>, then more detailed metadata is needed.<br />
Presumably this is what the statement from Steve means: &#8220;COS also implies that rich metadata glues everything together&#8221;. But where does this rich metadata come from?<br />
Centera effectively required programming their API and that&#8217;s where REST/SOAP would come in with Atmos. Unfortunately unless there&#8217;s a good method for creating the rich metadata, then Atmos is no better than the other unstructured data technology out there.<br />
To quote Steve again: &#8220;Rich metadata in the form of policies is the special sauce behind Atmos and is the reason for the creation of a new class of storage system.&#8221;</p>
<p>Yes, it sure is, but where is this going to come from?<br />
Finally, let&#8217;s talk again about some of the built-in policies Atmos has:
</p>
<p style="margin: 0cm 0cm 0pt 36.15pt; background: white none repeat scroll 0% 0%; direction: ltr; text-indent: -18pt; text-align: left;" dir="ltr"><span style="font-size: 10pt; font-family: Symbol;"><span>·<span style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal; font-family: 'Times New Roman';"> </span></span></span><span dir="ltr"><span style="font-family: Times New Roman;">Replication </span></span></p>

<p style="margin: 0cm 0cm 12pt; background: white none repeat scroll 0% 0%; direction: ltr; text-align: left;" dir="ltr"><span style="font-family: Times New Roman;">All of these exist in other products and are not innovative. However extending policies is more interesting; although I suspect this is not a unique feature either.</span></p>
<p>On reflection I may be being a little harse on Atmos, however EMC have stated that Atmos represents a new paradigm in the storage of data. If you make a claim like that, then you need to back it up.<br />
So, still to be answered;</p>
<p style="margin: 0cm 0cm 0pt 36.15pt; background: white none repeat scroll 0% 0%; direction: ltr; text-indent: -18pt; text-align: left;" dir="ltr"><span style="font-size: 10pt; font-family: Symbol;"><span>·<span style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal; font-family: 'Times New Roman';"> </span></span></span><span dir="ltr"><span style="font-family: Times New Roman;">What resiliency is there to cope with component (i.e HDD) failure? </span></span></p>

			<content:encoded><![CDATA[<p>Show me a profitable business application-as-a-Service (SaaS) company.</p>
<p>There is a lot of trade talk about the success of Salesforce.com. Here is a company with a $3.2BN market cap as of Oct 26, 2008 currently trading at 24 down from 72, 5 months ago.</p>
<p>In 2007 &#8211; SF.com  posted a net income of $480K on revenue of $497M. Compare this to BMC Software,  a software vendor that provides system and service management solutions for the enterprise. BMC has a current market cap of $4.2BN, trading at 23 down from 39, 3 months ago. In 2007 &#8211; BMC Software posted $215M net income on $1.5BN in sales.</p>
<p>In plain language &#8211; Salesforce.com does not or cannot charge high enough prices for their services to sustain long-term profitability and growth.   At low price points; Free Open Source on inexpensive hosting becomes a highly-competitive alternative, especially for an SME.</p>
<p>Five years ago &#8211; the barrier to entry was application functionality but today, Free Open Source line of business applications like Sugar CRM Community edition are mature, full-featured applications with very little, if any, missing features and some unique advantages that Open Source offers.  Salesforce.com imposes a unique IP address/user constraint which can be very annoying. In SugarCRM, if you get <strong>User logged out when IP dynamically changed</strong>, just change 1 line in config.php</p>
<div>&#8216;verify_client_ip&#8217; =&gt; true, to false</div>
<p>Suppose you need a CRM system (if you&#8217;re a large shop, you already have one &#8211; like Siebel). We&#8217;re a small group of 5 guys &#8211; and we were using Salesforce.com with one of our business partners and wanted to use SF.com for our own business. The cost is $325/month or almost $4,000/year for 5 users. You can get 90% of the functionality from Sugar CRM for the cost of a onetime installation (which will take less than an hour of your time or about $150 if you pay someone) and $15/month for the hosting (if you use dreamhost.com, like we do). That&#8217;s a net savings of $3,000 / year.  dreamhost give us 700GB &#8211; more than SF.com, and the response/time is at least as good.</p>
<p>I know you&#8217;re saying that <a title="Dreamhost" href="http://www.dreamhost.com" target="_blank">dreamhost.com</a> at $15/month can&#8217;t compete with the scalability, reliability and service levels of SF.com. Maybe,  maybe not &#8211; but if you want muscle &#8211; consider <a title="Mosso" href="http://www.mosso.com" target="_blank">Mosso</a>.</p>
<p>For $100 per month, Mosso will sell you 80 GB of SAN storage, 2000 GB of bandwidth, a control panel to create sites, email accounts, databases, etc. and customer support.</p>
<p>Mosso says it takes radically different approach to Web hosting, using enterprise-level architecture. It deploys each website across clusters of servers, so when a server crashes or a hard drive fails, the other servers in the cluster pick up the slack without downtime. Their promise: for every 1 hour of downtime, they will reimburse you for 1 day off your bill.</p>
