Today, Dell announced the addition of 3 new blade servers to its PowerEdge portfolio – the PowerEdge M820, PowerEdge M520 and the PowerEdge M420.  Each server offers a unique addition to the Dell blade server family and will be available soon.

 PowerEdge M820

The PowerEdge M820 is a full-height, 4-socket blade server that is the first to use the Intel Xeon E5-4600 processor family.  The M820 has 48 DIMMs for up to 1.5TB of memory and comes with 2 x Select Network Adapters providing a choice between 10Gb Brocade, Broadcom or QLogic.  The server also has 4 additional I/O mezzanine card slots capable of holding additional 10Gb, Infiniband or Fibre cards.  The PowerEdge M820 will be available to purchase in mid-Q2 2012.  Find out more at:

PowerEdge M520

If you are familiar with the Dell PowerEdge M610 blade server, then the new PowerEdge M520 shouldn’t be any surprise to you.  It offers the same form factor and the same amount of memory, but is based on the newer Intel Sandy Bridge CPU.  The PowerEdge M520 is a half-height, 2-socket blade server that uses the Intel Xeon E5-2400 processor family.  As with most of the servers in the E5-2400 family, the M520 has 12 DIMMs for up to 192GB of memory.  Unlike the M820 or the M620, the PowerEdge M520 does not come with the Select Network Adapter, but instead comes standard with 4 x 1GbE Dual Port LOM.  (It is important to note, that a 48-port Blade Module, like the PowerConnect M6348, is required to have all 4 NICs available for use; otherwise only 2 of the 4 are available.) The server also has 2 additional I/O mezzanine card slots capable of holding additional 10Gb, Infiniband or Fibre cards.  The PowerEdge M520 is scheduled to be available for purchase in the next few weeks.  Find out more at:

PowerEdge M420

The PowerEdge M420 is a quarter-height, 2-socket blade server that uses the Intel Xeon E5-2400 processor family.  The M420 introduces a new concept to Dell’s blade family by allowing up to 32 servers within a single Dell PowerEdge M1000e blade chassis.  Each PowerEdge M420 blade server has up to 2 x Intel Xeon E5-2400 CPUs, 6 DIMM slots (for up to 96GB of memory), 2 internal SD slots, a Dual Port 10Gb Broadcom 57810s onboard NIC, 1 x mezzanine expansion.

The M420 quarter-height blades are deployed in the M1000e using a full-height sleeve known as a “subassembly”.  While each sleeve does not need to be fully populated with M420 blades in order to be installed, it does occupy the same physical space as a full-height blade, however it can be positioned adjacent to other half-height servers.  The M420 offers a great platform for any application using a lot of CPU processing.  A 42U rack can hold 4 x Dell PowerEdge M1000e chassis and each chassis can hold 32 PowerEdge M420 server.  That means you can have up to 128 Dell PowerEdge M420s in a rack.  Each M420 can hold 2 x Intel Xeon E5-2400 CPUs with a total of 16 CPU cores so that equates to 2,048 CPU cores in a rack. 

The PowerEdge M420 is scheduled to be available for purchase in the next few weeks.  Find out more at: http://www.dell.com/us/enterprise/p/poweredge-m420/pd?~ck=anav

Dell recently published a new whitepaper that compares the performance and power efficiency of four of the Dell PowerEdge M710HD and M620 blades vs. four of the Cisco B250 M2 blade servers.  Here is a summary of the key findings:

Performance / watt

The higher performance and lower power draw of the four-blade Dell solutions compared to the UCS B250 M2 blade solution led to the PowerEdge M710HD solution’s 76% higher performance per watt score and the PowerEdge M620 solution’s 108% higher performance per watt score.

Power at Idle

Even with all blades configured with the same amount of system memory, the four-blade PowerEdge M710HD solution consumed 58% as much power at idle as the four-blade UCS B250 M2 solution with its extra DIMMs and supporting circuitry. Similarly, the four-blade PowerEdge M620 blade solution drew just 55% as much power at idle as the Cisco blade solution.

Power at 100% Load

Both of the four-blade PowerEdge solutions, again with the same amount of system memory installed per blade, drew 64% to 67% as much power as the four-blade Cisco UCS B250 M2 blade solution with all blades running at 100% load.

Performance

With the same processor models and the same memory capacity installed in each blade, the four-blade solution based on PowerEdge M710HD blades provided up to 11% higher performance than the four-blade solution based on UCS B250 M2 blades, and the four-blade solution based on PowerEdge M620 blades provided up to 25% higher performance than the UCS blade solution.

Rack density

When the 10U M1000e Modular Blade Enclosure is equipped with its maximum of sixteen M710HD or M620 servers, the solution can fit 1.6 servers per rack unit of space, 2.4 times as dense as the solution with Cisco UCS B250 M2 blades.

Cost

In the configuration tested, the Cisco UCS B250 M2 blade solution costs $112,591.02[1], while the similarly configured Dell PowerEdge M710HD solution costs 34% less at $73,820.00, and the PowerEdge M620 solution costs 33% less at $75,372.00.

(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® E5-2620 2.00GHz, 15M Cache, 7.2GT/s QPI, Turbo, 6C, 95W
Intel® Xeon® E5-2630 2.30GHz, 15M Cache, 7.2GT/s QPI, Turbo, 6C, 95W
Intel® Xeon® E5-2640 2.50GHz, 15M Cache, 7.2GT/s QPI, Turbo, 6C, 95W
Intel® Xeon® E5-2667 2.90GHz, 15M Cache, 7.2GT/s QPI, Turbo, 6C, 130W

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.

In anticipation of Intel’s upcoming E5-2600 CPU (aka Sandy Bridge) announcement, Dell officially announced the 12th Generation of PowerEdge servers today.  Although the specifics of the 12th Generation, or “12G”, servers have not yet been released, it is very clear there will be a new blade server added to the Dell PowerEdge portfolio: the M620.

While Dell.com announcement site does not have a lot of the details of what’s coming in 12G, The Register has been able to secure some good information on the Dell PowerEdge M620 blade server that I’ll share with you.

1. The M620′s size is “half-height”allowing you to put up to 16 inside of the Dell PowerEdge M1000e chassis.
2. It will hold up to 2 x Intel Xeon E5 CPUs
3. It will hold up to 768GB of RAM (the same as its tower and rack equivalent)
4. The M620 has two hot-plug, 2.5-inch drive bays, and can have SSD, SATA disk, or SAS disk drives slid into those two slots. 
5. The PERC S110 controller with software raid and the PERC H310, H710, and H710P controllers for internal RAID arrays can snap onto this M620 blade. 
6. The M620 has two SD cards for redundant embedded hypervisors to sit on.

Of course, there are a few other goodies that The Register didn’t mention – so I’ll hold off talking about until the official Intel announcement.

Hot off the presses is the latest IDC worldwide server market revenue report for Q3 2011. The gist of the report is that while some of the numbers are slightly adjusted, really not much has changed in the blade server market.

Revenue growth for the entire server market (all servers, not just blade servers) slowed considerably showing only 4.2% year over year growth bringing in $12.7 billion. Growth in the world of servers continues but this marks the slowest growth rate for any quarter since Q1 2010. IDC believes that overall server sales will continue to decelerate due to weakening economic conditions around the globe. “After nearly two years of steady revenue growth, the server market began to decelerate in Q3 2011 as demand stabilized for many system categories,” said Matt Eastwood, group VP and general manager. Incidentally, IBM and HP are both holding steady, tied for the #1 spot in revenue share, at 29.8%.

When looking at the blade server market specifically, growth was steady for Q3 2011 but not as explosive as Q2 2011. IDC reports “solid growth” in the quarter with a revenue increase of 16.4% year over year (vs 26.9% growth in 2Q11). Shipments increased 2.4% (vs 6.2% reported growth for 2Q11). One thing that hasn’t changed since last quarter is that 89% of all blade revenue is driven by x86 systems. Also, blade server sales representing  20.8% of all x86 server revenue. This shows continued steady growth for the blade server segment but that the pace may be slowing slightly.

#1 market share: HP managed to hold the majority margin moving to 51.0% in Q3 2011 from 51.9% in Q2 2011.

#2 market share: IBM continues to see its margin chipped away slightly down to 18.5% in Q3 2011 from 19.1% in Q2 2011.

#3 market share: Cisco’s disruptive market penetration seems to have slowed at 10.7% overall compared to a solid 10% in Q2 2011.

#4 market share: Even Dell dropped slightly to 7.2% revenue share from 8.2% last quarter.

In looking at the totals, the top four vendors represented 87.4% of the revenue share in the blade servers market which is actually down 2% from last quarter. Cisco grew revenue share by less than 1% which means that some of the displacement of the remaining top vendors is not accounted for. Does this mean there may be some new players in the “others” category that we should be watching? Without a detailed breakdown it’s hard to tell but I’ll definitely be looking forward to comparing the numbers next quarter to see if the trend continues. It could, after all, just be a factor of the margin of error in the statistics.

According to Jed Scaramella, research manager, Enterprise Servers at IDC, “Blade systems represented the fastest growing segment in the server industry and now account for 16.0% of total server revenue – a historic high.”

Probably the most interesting aspect of the report is the introduction of hyper-scale servers. “Hyper-scale servers are designed for large scale datacenters with streamlined system designs that focus on performance, energy efficiency, and density.” This sounds like the mantra for blade servers with the main difference being the lack of management and high availability capabilities at the hardware level. Basically these represent the miles of simple, rack mount commodity servers used by the likes of Google and Facebook. This is a $428 million dollar server segment and growing.

If you are a reader of BladesMadeSimple, you are no stranger to Dell’s Network Daughter Card (NDC), but if it is a new term for you, let me give you the basics. Up until now, blade servers came with network interface cards (NICs) pre-installed as part of the motherboard.  Most servers came standard with Dual-port 1Gb Ethernet NICs on the motherboard, so if you invested into a 10Gb Ethernet (10GbE) or other converged technologies, the onboard NICs were stuck at 1Gb Ethernet.  As technology advanced and 10Gb Ethernet became more prevalent in the data center, blade servers entered the market with 10GbE standard on the motherboard.  If, however, you weren’t implementing 10GbE then you found yourself paying for technology that you couldn’t use.  Basically, what ever came standard on the motherboard is what you were stuck with – until now.

 Dell has broken the long-standing design concept of embedding the LAN onto the motherboard (aka LOM) and replaced it with a small, removable mezzanine card called a Network Daughter Card, or NDC.  The NDC provides the buyer with a flexibility of choosing what they want ( 4 x 1GbE, 2 x 10GbE or 2 x Converged Network Adapter.)  This innovation is exciting to me, as it not only provides a possible upgrade path to future technologies, but it also changes the way we look at server technology.  No longer does the on-board NIC have to be integrated onto the motherboard, but it can be a removable card that can be easily replaced or upgraded.  In a few years when this is standard architecture on every x86 server, remember where you saw it first.

But wait – there’s more.  In addition the NDC is the first adapter to offer the industry’s first network partitioning, or “NPAR” scheme that makes it possible to split the 10GbE pipe while working with any of the Dell PowerEdge M1000e 10GbE Ethernet Switch Modules.  So, what’s the big deal about NPAR?  Let me explain.

With the increased amount of virtualization in the data center, combined with an increase in data and cloud computing, the network’s efficiency is becoming compromised driving many organizations to embrace a 10GbE network.  While moving to a more robust 10GbE environment may be ideal for an organization, it also brings challenges like ensuring that the appropriate bandwidth for all resources is available in both the physical and virtual environments.  This is where NPAR comes in.  Network Partitioning allows for administrators to split up  the 10GbE pipes on the NDC into 4 separate partitions or physical functions and allocate bandwidth and resources as needed.  Each of the four partitions is an actual PCI Express function that appears in the blade server’s system ROM, O/S or virtual O/S as a separate physical NIC. 

Each partition can support networking features such as:

• TCP checksum offload
• Large send offload
• Transparent Packet Aggregation (TPA)
• Multiqueue receive-side scaling
• VM queue (VMQ) feature of the Microsoft® Hyper-V™ hypervisor
• Internet SCSI (iSCSI) HBA
• Fibre Channel over Ethernet (FCoE) HBA.

Administrators can enable/disable any of the features per partition and they configure a partition to run iSCSI, FCoE, and TCP/ IP Offload Engine (TOE) simultaneously.

Each of the four partitions per port (8 per NDC) can be set up with a specific size and a specific weight.  In the example shown on the above, you see that Physical Port 1 has 4 partitions:

• Partition 1 (red) = 2Gbps, running as an iSCSI HBA on Microsoft Windows Server 2008 R2
• Partition 2 (orange) = 2Gbps, running as an FCoE HBA on Microsoft Windows Server 2008 R2
• Partition 3 (green) = 1Gbps, running TOE on on Microsoft Windows Server 2008 R2
• Partition 4 (blue) = 5Gbps, running as a Layer 2 NIC on Microsoft Windows Server 2008 R2

Each partition’s “Maximum Bandwidth” can be set to any increment of 100Mbps (or .1Gbps) up to 10000 Mbps or 10 Gbps.  Also, note, this is for send/transmit only.  The receive direction bandwidth is always 10 Gbps.

Furthermore, admins can configure the weighting of each partition to provide increased bandwidth presence when an application requires it.  In the example above, Physical Port 2 has the “Relative Bandwidth Weight” on all 4 partitions set for an equal weight at 25% – giving each port equal weight.  If, however VMkernel NIC 1 (red) needed to have more weight, or priority, over the other NICs, we could set the weight to 100% giving that port top priority.

If you are feeling really adventurous, you can oversubscribe a port.  This is accomplished by setting the 4 partitions of that single port to having a Maximum Bandwidth setting of more than 100%.  This allows each of the partitions to take as much bandwidth as allowed as their individual traffic flow needs change – based on the Relative Bandwidth Weight assigned.  Take a look at the following:

The example above shows each of the four partitions’ Maximum Bandwidth (shown in .1 increments so 10 = 1 Gbps)

• Partition 1 = 1 Gbps
• Partition 2 = 1 Gbps
• Partition 3 = 8 Gbps
• Partition 4 = 8 Gpbs

Total for all 4 partitions = 18 Gbps, which means the port is 80% (8 Gbps) oversubscribed.

Some additional rules to note from the NPAR User’s Manual:

• For Microsoft Windows Server, you can have the Ethernet Protocol enabled on all, some, or none of the four partitions on an individual port.
• For Linux OSs, the Ethernet protocol will always be enabled (even if disabled in Dell Unified Server Configuration screen).
• A maximum of two iSCSI Offload Protocols (HBA) can be enabled over any of the four available partitions of a single port. For simplicity, it is recommended to always using the first two partitions of a port for any offload protocols.
• For Microsoft Windows Server , the Ethernet protocol does not have to be enabled for the iSCSI offload protocol to be enabled and used on a specific partition.

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.

I always find it interesting to hear how customers are using blade server technology “in the real world.”   Brickworks, a $1.7 billion Australian brick company with over 60 locations and 1,000 employees, recently provided The Australian with details about how Citrix XenApp Enterprise combined with VMware vSphere and Dell rack and blade servers helped develop a more efficient workplace for its employees.  Read the full article at:
