Why Are Dell’s Blade Servers “Different”?
I’ve learned over the years that it is very easy to focus on the feeds and speeds of a server while overlooking features that truly differentiate. When you take a look under the covers, a server’s CPU and memory are going to be equal to the competition, so the innovation that goes into the server is where the focus should be. On Dell’s community blog, Rob Bradfield, a Senior Blade Server Product Line Consultant in Dell’s Enterprise Product Group, discusses some of the innovation and reliability that goes into Dell blade servers. I encourage you to take a look at Rob’s blog post at http://dell.to/mXE7iJ.
I also want to highlight some other innovations that Dell is offering on certain blade servers:
Network Daughter Card (NDC) – unlike the network interface cards built into the blade server motherboard, the NDC is a daughter card that offers choices of 4 x 1Gb NICs, 10Gb NICs or CNA. The NDC is a new feature and not offered on every blade server, but for more info, check out this earlier blog post I wrote: http://bladesmadesimple.com/2011/05/a-review-of-the-dell-poweredge-m710-hd-blade-server/
Network Interface Card Partitioning (NPAR) – this is a feature found on certain blade server models that allows you to divide up the onboard 10Gb NICs into “virtual NICs”. The cool thing is this can be performed without a specific network I/O module so you don’t have to worry about being locked into any specific I/O module and without the use of any CPU overhead or specialized software. Read more about this at http://bladesmadesimple.com/2011/04/dellapril5announcements/.
Let me put these innovative features into a real life scenario (note – this is simply an example and doesn’t confirm or deny any future product release from Dell.) Imagine today you invest into a blade server with a 10Gb NDC using NPAR to split up the 10Gb pipe into smaller 1Gb virtual NICs. and 10Gb capable Ethernet I/O Module and in 18 months, a 40Gb Ethernet Switch module comes out. You could theoretically replace the NDC and the Ethernet module with the 40Gb flavor (if/when it ever is available)
The next time you choose a server, look beyond the speeds and feeds and look at the innovation, the reliability and the value the server can offer.
