Dell’s PowerEdge M620 Blade Server Offering Up to 768GB RAM

(UPDATED 3/7/12) With the launch of Intel’s Xeon E5-2600 processor, Dell revealed the details of the new PowerEdge M620 blade server.  Offering an industry first 24 memory DIMMs in a half-height form factor, the M620 offers up to 768GB of RAM along side the newly announced Intel E5-2600.  The Dell PowerEdge M620 also comes with the ability to chose from a variety of LOM (LAN on Motherboard) cards – a feature first seen in the PowerEdge M710HD and M915 last Summer.  Formerly known as the Network Daughter Card, the newly renamed feature, called Select Network Adapter, is a removable network card that gives buyers the option of choosing from Broadcom, Intel or QLogic adapters – each offering up to two ports of 10Gb.  Since it is removable, it offers investment protection as new technology becomes available.  For more features and details about the M620, see below.

CPU Offerings

At the time of launch, Dell is offering the following Intel E5-2600 CPUs on the M620:

Intel® Xeon® E5-2650L 1.80GHz, 20M Cache, 8.0GT/s QPI, Turbo, 8C, 70W
Intel® Xeon® E5-2650 2.00GHz, 20M Cache, 8.0GT/s QPI, Turbo, 8C, 95W
Intel® Xeon® E5-2660 2.20GHz, 20M Cache, 8.0GT/s QPI, Turbo, 8C, 95W
Intel® Xeon® E5-2665 2.40GHz, 20M Cache, 8.0GT/s QPI, Turbo, 8C, 115W
Intel® Xeon® E5-2670 2.60GHz, 20M Cache, 8.0GT/s QPI, Turbo, 8C, 115W
Intel® Xeon® E5-2680 2.70GHz, 20M Cache, 8.0GT/s QPI, Turbo, 8C, 130W

Intel® Xeon® E5-2630L 2.00GHz, 15M Cache, 7.2GT/s QPI, Turbo, 6C, 60W

Intel® Xeon® E5-2603 1.80GHz,10M Cache, 6.4GT/s QPI, No Turbo, 4C, 80W
Intel® Xeon® E5-2609 2.40GHz, 10M Cache, 6.4GT/s QPI, No Turbo, 4C, 80W
Intel® Xeon® E5-2637 3.0GHz, 5M cache, 6.4 GT/s QPI, Turbo, 2C, 80W

If you have software licensed by the core, you’ll be happy to see the E5-2637 CPU, which offers 2 CPU cores while maintaining a high 3.0GHz frequency.

 

Memory

Although the maximum memory speed with the Romley platform running the Intel Xeon E5-2600 CPU touts a 1600MHz memory performance speed, there is a trade off on capacity.  Basically, if you want a lot of memory, you’ll have to run the memory at a slower speed at 1033.   To help determine performance vs capacity, I’ve listed a chart below that should help decode things.  In the spirit of full disclosure, the 32GB DIMMs, which are required to achieve the maximum capacity of 768GB RAM, will not be available until Q2 2012 (date not provided at this time.)  To aid with your memory selection, check out:

LAN on Motherboard Options

As mentioned above, the PowerEdge M620’s on-board network is available in removable card, known as the Select Network Adapter.  While this is new to the M6xx family, it is Dell’s second generation of removal LOM cards.  In fact, with the 12G product launch, the Select Network Adapter can be found in the R620 and R720 rack servers too.  Below is a chart of the 3 card options, as well as the features they support.  In summary, if you want SR-IOV or DCB Support, you’ll want to go with the Intel X520 card – otherwise it’s a battle between Broadcom and QLogic.REVISED 3/7/12  – I clearly was under the influence of lack of sleep when I wrote this.  The matrix was all messed up.  Here is the CORRECT list of supported options:

Other New Options

The PowerEdge M620 comes with 2 x mezzanine I/O card expansion slots (x8 PCIe 3.0) fully available in both the 1 CPU and 2 CPU blade server designs.  I was planning on listing the options available for the mezzanine slots on the M620, but the list is too long, however you can find it on the M620 page at http://www.dell.com/us/enterprise/p/poweredge-m620/pd?~ck=anav.  Instead, I want to touch on a couple of other cool features that you might find valuable.

Dual embedded SD slots for Hypervisor – since the market is heading toward encouraging embedded hypervisors, Dell decided to place dual card slots into the M620 designed to be redundant.  If you lose your primary SD card, the secondary slot is available to resume the workload.

Now, for my final trick – SCAN THIS QR Tag:

Welcome to the future.  No longer will you have to search for assistance with a server product.  With the 12th Generation of the Dell PowerEdge servers, Dell is introducing the concept of using QR tags to offer technical assistance in the form of step-by-step videos, reference materials and even help with looking up your service tag.
