IBM officially announced their new blade, the HS23 blade server, and it comes with some improvement.

The HS23 blade server is a dual CPU socket blade running Intel´s new Xeon® processor, the E5-2600,  and is the first IBM BladeCenter server that offers four integrated LAN ports: dual-port Gigabit Ethernet and dual-port 10Gb Ethernet with IBM Virtual Fabric capability.

It has the same 30mm single-wide form-factor of all other IBM blades to protect customers’ investment by providing compatibility with the IBM BladeCenter H, E, S, and HT chassis.

The HS23 blade server  scales up to 14 virtual NICs (vNICs) per single-wide blade server for a total of 18 I/O ports with the choice of Ethernet, Fibre Channel, SAS, iSCSI, and FCoE connectivity.  One thing to note – this new high-speed adapter n the IBM HS23 blade server will work only in BladeCenter H chassis.  The blade server can provide up to four 10GbE (same as HS22 and HS22V), but the difference is that HS23 comes standard with  two 10GbE Virtual Fabric ports. Another CFFh virtual Fabric can be added to provide connectivity with the other two high-speed switches.

For those that are familiar with the I/O paths in Chassis H, here is how it works when using the Emulex Virtual Fabric Adapters:
 two 10 Gb Ethernet ports on the adapter itself are routed to the chassis I/O bays 8 and 10 (unlike other CFFh cards), and two 10 Gb Ethernet ports integrated on a blade itself are routed to the chassis I/O bays 7 and 9.

But if you do not want to use this technology (Virtual Fabric) you have to remove the 10Gb LOM Interposer in order to be able to add another CFFh expansion card like a QLogic Ethernet and 8Gb Fibre Channel Expansion Card, which enables connectivity between the blade and two Ethernet switches and two SAN switches.   Again, BladeCenter H only.

Other features of the HS23 blade server:

Processors

Up to two Intel Xeon processor E5-2600 product family CPUs with eight-core (up to 2.7 GHz) ; six-core (up to 2.9 GHz) ; quad-core (up to 2.4 GHz) or dual-core (up to 3.0 GHz). Two QPI links up to 8.0 GT/s each. Up to 1600 MHz memory speed. Up to 20 MB L3 cache.
Memory

Up to 16 DDR3 DIMM sockets (8 DIMMs per processor) using Very Low Profile (VLP) DIMMs. Support for up to 1600 MHz memory speed depending on the processor. Four memory channels per processor (2 DIMMs per channel). Up to 256 GB with 16x 16 GB RDIMMs and two processors.
Mixing 1.5 V and 1.35 V DIMMs in the same server is supported. In such a case all DIMMs operate at 1.5 V.
Disk Bays

Two 2.5″ hot-swap SAS/SATA drive bays supporting SAS, SATA, and SSD drives.

HS23 comes to replace both HS22 and HS22V on IBM portfolio. Positioned just below HX5, HS23 is designed to meet the needs of small/ midsized businesses and is ideal for a variety of workloads including virtualization and cloud infrastructure solutions.

HP launched the new  ProLiant BL460c Gen8 blade but you would have never known about it.   With the prelaunch work done it February it seemed like a non event.   The bulk of the goodness on the Gen 8 updates are across the ProLiant  family so I will try to keep my focus on those that pertain to the  BL460c.

The BL460c is focused around the new Intel Xeon E5-2600 Family  processors with up to 8 cores/16 threads each, advanced memory capabilities and new cloud ready management .

One interesting thing I saw today when trying to get find out more  information was that you need both processers installed to use both PCIe 3.0 slots. Just something to keep in mind.

Memory

New HP SmartMemory is qualified to run at speeds up to 25 percent faster than industry standards but there is a catch. HP memory from previous generation servers are not qualified to run with Gen 8 Blade.  The HP SmartMemory has to pass testing by HP before meeting qualification. The best part about the new architecture is not having to guess if the amount of memory you put in the server will reduce the overall speed. It use to be if you filled all three DIMMs per channel performance would drop. The ProLiant BL460c Gen8 has four memory controllers per processor socket so that memory speed and capacity is not affected as more memory are added. When using the correct combination of processors and DIMMs, the server supports operating all 16 DIMMs at 1600MHz providing up to 256 GB for maximum memory speed or 1333MHz providing up to 512 GB for maximum memory capacity.

Standard (Pre-configured Models)
64GB (8 x 8GB) DDR3 1600MHz RDIMMs at 1.5V
32GB (4 x 8GB) DDR3 1600MHz RDIMMs at 1.5V
32GB (4 x 8GB) DDR3 1333MHz RDIMMs at 1.35V
16GB (4 x 4GB) DDR3 1333MHz RDIMMs at 1.35V

Maximum (LRDIMM)
512GB (16 x 32GB) up to 1333MHz at 1.35V
Maximum (RDIMM)
256GB (16 x 16GB) up to 1600MHz at 1.5V
256GB (16 x 16GB) up to 1333MHz at 1.35V
Maximum (UDIMM)
128GB (16 x 8GB) up to 1333MHz at 1.35V

The maximum RAM capacity is only based on 16 GB DIMMS but 32 GB will follow soon. There was even a non HP announcement today about 64GB DDR3 LRDIMM’s.

Cloud Management

The new management capabilities for Gen 8 have seem to come along away. In the end all the server vendors are playing with Intel , so this area is probably where the most vendors will differentiate themselves . My favourite new feature is the HP Active Health System.
All configurations change are logged, failed parts are tracked so they don’t get but back in and all the Active Health information can be sent to support automatically so I don’t have to stay on the phone with support.

The cloud based management is based on HP Insight Online. The portal gives you access to monitor your servers, warranty and contracts, service tickets and allows for replacement parts to be proactively ordered. You can give your partners access your portal for remote management and but it looks like automatic (direct-to-expert) support will cost you some additional dollars.

It’s also worth noting that HP changed their drives to better report and show drive failures. The old hard drives will not work in the new
blades.

As more information is released I plan to write about the impact for VDI on my blog at ITbloodpressure.com.

(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.

Intel announced on Tuesday their next generation of 2 socket CPU – the Intel Xeon E5-2600.  Formerly code named, “Sandy Bridge,” the E5-2600 is a follow on to the Intel Xeon 5600 series family and offers a real performance increase.  In fact, Intel is boasting performance increases from 43% to 62% (depending on the vendor and benchmark.)  What is contributing to this massive increase in performance?  Let’s take a look.

Compared to previous generation Intel Xeon 5600, the Intel Xeon E5-2600 provides:

• Additional CPU Cores – up to 2 additional CPU cores and Up to 8MB more cache
• Increased Memory – up to 24 DDR3 Memory DIMMs are available per 2 CPU system.  In addition, 32GB DIMMs are supported giving a maximum capacity of 768GB RAM (in a 2 CPU configuration.)
• Higher Bandwidth – not only does Intel add a 2nd Quick Path Interconnect (QPI) between the CPUs, they also increased the maximum communication speed to 8.0 GigaTransfers per Second (GT/s).  Compared to the Intel Xeon 5600, which had a single QPI that ran at 6.4GT/s, the intra-CPU communication alone provides huge performance gains.  Not to be overlooked, Intel also increased the maximum throughput on the memory channels from 1333MHz to 1600MHz.
• Tighter Integration – the Intel Xeon E5-2600 marks the beginning of a new era of I/O.  The PCI express lanes are now integrated into the platform providing up to 40 lanes of PCIe communication directly to the CPU.  Previous generations used an I/O Hub (or IOH) which served as a sort of traffic cop for PCIe I/O.  With the PCIe being integrated into the chipset, I/O communication is up to 30% faster and provides additional power savings.  Intel’s integration of the PCIe I/O subsystem into the CPU will allow for near future performance using PCIe 3.0 peripherals to provide a 2X performance over previous PCIe generations.

When you combine all of this together, you have a two socket CPU capable of running 16 CPU cores (32 if using Hyper-Threading), 24 memory DIMMs with a maximum capacity of 768GB RAM and 80 PCIe 3.0 I/O lanes. Up until now, these numbers were only available in a large rack mount server but with the release of the Intel Xeon E5-2600, we can now expect to see this performance and ability in 1U servers and even in a blade server form factor. 

Other Improvements
While the Intel Xeon E5-2600’s performance over the previous Intel Xeon 5600 is the sexy part of the new offering, there are some other features that shouldn’t be overlooked:

• Better Performance at Lower Power – the improvement in the architecture has allowed Intel to achieve up to 70% better performance at the same power footprint.  This is done by allowing the system to reduce the power to the memory, cache, I/O and other CPU functions when performance isn’t needed (i.e. when idle.)  As well, the CPUs takes advantage of Intel Intelligent Power Technologies like integrated power gate, but that is a bit out of the scope of my goal of “keeping things simple” – so head over to Intel for more on that topic.
• New Intel Advanced Vector Extensions (AVX) – according to Intel, “AVX is a collection of CPU instructions that increase floating point performance by doubling the length of the FP registers to 256-bits and reducing the number of operations required to execute large FP tasks.”  In other words, it allows the CPU to do more complicated instructions quicker.  If you run technical, financial, scientific & content creation applications – you probably already know about AVX, so get excited – AVX is better with the Intel Xeon E5-2600.

The International Data Corporation’s (IDC) released their  Worldwide Quarterly Server Tracker today covering Q4 2011.  Despite a 7.2% decrease in the worldwide server factory revenue, the blade market continued to experience growth in 4Q11 with factory revenue increasing 8.3% year over year.   Other key facts from the IDC press release:

• Bladed servers (including x86, EPIC, and RISC blades) accounted for $2.3 billion in revenues, or 16.1% of quarterly server market revenue.
• 89.6% of all blade revenue is driven by x86-based blades, which now represent 22.5% of all x86 server revenue.

HP maintained the number 1 spot in the server blade market in 4Q11 with 47.4% revenue share – down from 51% in 3Q11, while IBM grew from 18.2% in 3Q11 to 21.5% revenue share in 4Q11. Cisco and Dell rounded out the top 4 blade server vendors with 11.0% and 8.7% factory revenue share, gaining 5.3 and 1.3 points of blade market share, respectively from Q311.

According to Jed Scaramella, research manager, Enterprise Servers at IDC, “While there was softness in other segments, blades remained a strong point and continued as a driver of growth for the server market. The blade server category achieved both its highest reported revenue and revenue share in the fourth quarter of 2011.  IDC believes blades are a key element in a server vendor’s portfolio as they are a strategic footprint in the datacenter and important for vendor revenue and profitability. A converged blade platform is an opportunity for additional pull-through revenue beyond the server, including storage, networking, software, and services.”

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.

As I mentioned yesterday, one of my fellow bloggers, Stephen Foskett, is writing a series on blade servers.  His latest post reveals the history of the blade server.  Stephen’s article challenged me to do some research of my own – and here’s what I found.   Apparently the first “official” patent for a server on blade (patent # 6,411,506 - “High density web server chassis system and method) was awarded in June of 2002 to Christopher G. Hipp and David M. Kirkeby of RLX Technologies.   One interesting fact is that U.S. Patents referenced within the document refers to other patents from many leaders of the industry including IBM, Hewlett-Packard, Micron, Hitachi and even Dell.

I’ve taken the liberty of downloading the entire patent document for your reference:

My friend, Stephen Foskett, is writing a series of posts introducing blade servers.  It’s probably something I should have done a long time ago, but since I’m a slacker and he beat me to it, I’ll give him kudos and do a re-post.  I encourage you to read the full article as it’s very enlightening.  Here is an excerpt:

“I’ve been watching enterprise IT for over 20 years now, and I’ve seen some radical changes. In the server space, one of the biggest shifts was the form factor of the servers: From tower to rack-mount to blades. But what makes a blade server anyway? Let’s consider this for a moment, as we watch another shift in progress.  Blade servers are easily recognized in the data centers, trade shows, and product catalogs of today: They’re the ones that nestle together in an enclosure, sharing some resources rather than standing on their own in a rack or on the floor.
