			<content:encoded><![CDATA[<p>In my previous company I had the opportunity to work with a <a href="http://h18004.www1.hp.com/products/blades/components/enclosures/c-class/c7000/">HP BladeSystem c7000 enclosure</a>.  It was a very nice piece of equipment.  It provided a fully power and network-redundant backplane, albeit at a premium.  Easy to manage, and took up only 10 U&#8217;s for 16 servers.</p>
<p>I&#8217;m  looking to implement a similar solution at the new place, and in the interest of due diligence and curiosity I decided to look into the <a href="http://www.dell.com/content/products/productdetails.aspx/pedge_m1000e?c=us&amp;cs=RC968571&amp;l=en&amp;s=hea" title="Dell Blades">Dell solution</a>.  On paper, it looks promising: sips less power than the HP, has a nice feature set, actually looks a little nicer than the HP chassis.</p>
<p>I set up a meeting with my Dell SMB rep to spec out a system with a Blade server specialist.   I like what I&#8217;m hearing so far &#8212; six redundant power supplies, iKVM, DRAC (aka HP&#8217;s iLO2).</p>
<p>We come to the dreaded switch question.  I&#8217;ve heard <a href="http://episteme.arstechnica.com/eve/forums/a/tpc/f/833003030931/m/259008712931?r=732001812931#732001812931" title="The Server Room Forum">stories</a> about this before.</p>
<p>Okay, it was one story.  But we all know if there&#8217;s one major weakness in Dell&#8217;s product line, it&#8217;s the switches.  They may be good, they may be getting better, but the enterprise industry in general doesn&#8217;t trust in them much yet.  At least from what I&#8217;ve seen.  They&#8217;ll buy Dell rack servers, they&#8217;ll buy the storage solutions, but they look to Cisco or HP to provide their network infrastructure.</p>
<p>Anyhow, back to my conversation.</p>
<p>I  ask about putting in switch modules in the back.  10GBe over copper (CX4) interconnects.  I tell him I&#8217;m getting an EqualLogic PS5000XV and it&#8217;s going directly into those switch modules.</p>
<p>He stops me right there.  &#8220;Those switch modules will hold that SAN back.  I recommend you use pass-through and connect the Blades to another [Non-Dell] switch&#8221;.</p>
<p>I was a little taken back.  One of the bigger reasons I&#8217;m going with a Blade enclosure is because of that 10 GBe backplane.  No wires.  If anything, it made my life easier.  I was even more surprised that Dell would be actually telling me that their switches would not be a fit.  Honesty is good and fair in this business and I respect that he told me that.</p>
<p>But I knew he was wrong.  The EqualLogic will work with commodity switches &#8212; it&#8217;s all about how you configure your network.  If it&#8217;s a standard enterprise-level switch that supports things like jumbo frames, VLANs, it&#8217;ll do the job.</p>
<p>Perhaps I&#8217;m expecting a systems guy to know networks, but I&#8217;m no network engineer either.  I think Dell just needs to have a better line when it comes to their switches, especially now that they own and sell EqualLogic which will be heavily dependent on those switches in the future.</p>
<p>When it&#8217;s all said and done, the price was about the same &#8212; I know the HP system well and am comfortable with it, so I&#8217;m deciding to go the HP route.  But I can&#8217;t say that this conversation didn&#8217;t have a factor in ruling out Dell.  The sad part is, I really did go into it willing to give Dell a shot at the business.  The technology was all there, I think no one at Dell really thought about how they needed to sell it.</p>
<p>I&#8217;m sorry, iSCSI storage and switches go hand in hand.  It doesn&#8217;t make sense for Dell to tout their servers and storage and bury their network line at a distant third.  Pump up the technology, pump up the sales routine and let&#8217;s see what happens.  That&#8217;s my hope.</p>

			<content:encoded><![CDATA[<p>There&#8217;s two big buzzwords in my industry nowadays: virtualization, and <a href="http://en.wikipedia.org/wiki/ISCSI" title="iSCSI">iSCSI</a>.  Both are related to some degree, as iSCSI SANs seems to work well with VMWare.  VMotion now even lets you hot-swap a VM from one hardware to another without shutting it down.</p>
<p>So &#8220;routeable storage&#8221; seems to be the future of the industry &#8212; Fiber Channel is just too expensive and FCoE seem a long ways from being mainstream.</p>
<p>I deal with an <a href="http://www.equallogic.com/">EqualLogic </a>(Now Dell) PS series at work and it&#8217;s been fantastic thus far.  Performance has been admirable (although it&#8217;d be nice if we had planned a storage switch network before implementation), and we initiate from a dozen different servers.  Administration is dead-simple.</p>
<p>There&#8217;s a lot of things we use that I think we didn&#8217;t need &#8212; but the SAN is worth its weight in gold.  The fact that the entirety of our SQL, network files and development data sits on a fully redundant RAID 10 array allows me to sleep a little more soundly at night.</p>
<p><em>Update</em>: Meta-props back to the folks at the <a href="http://direct2dell.com/insideit/archive/2008/04/18/Nice-unsolicited-post-by-a-customer_3A00_-VMware_2C00_-SQL.aspx" title="Inside IT">Inside IT Blog</a> at Dell, who gave this a mention on their blog.  Let me re-iterate my genuine support for EqualLogic.  I like that they don&#8217;t nickle-and-dime us for extra things like the Auto-Snapshot Manager and software updates.  You buy an EqualLogic and they&#8217;ll support you until the end for free.  I really, really hope that they never change this model.  One of the biggest reasons why I look in their direction whenever I need to recommend an iSCSI storage solution.</p>
<p>I am in no way shape or form affiliated with Dell, EqualLogic or ArsTechnica.  I&#8217;m a member of the Ars forums and as a vendor-agnostic consultant I always look for products and solutions that give the best value for my clients.</p>

			<content:encoded><![CDATA[<p>KPBS, San Diego&#8217;s public broadcasting branch, is using <a href="http://twitter.com/kpbsnews">Twitter</a> to send out news updates.</p>
<p>Considering how saturated the cell network gets during emergencies and how little bandwidth it takes to send SMS text messages, this is a great way to inform the masses.  I hope emergency management departments realize this and start including text messages to cell phones on top of its reverse-911 protocol to inform residents of evacuation procedures.</p>
<p>One of the biggest lessons we have to learn from this fire is to better distribute the information in a multi-site emergency.  While good I believe the response could be much improved in reducing the information delay.  I had to really dig to find out what was happening *now*, refreshing news websites, comment threads, etc.</p>
<p>My thoughts are out to everyone who has been displaced.  May they be safe.</p>
