New Cisco Blade Server: B440-M1

Cisco recently announced their first blade offering with the Intel Xeon 7500 processor, known as the “Cisco UCS B440-M1 High-Performance Blade Server.”  This new blade is a full-width blade that offers 2 – 4 Xeon 7500 processors and 32 memory slots, for up to 256GB RAM, as well as 4 hot-swap drive bays.  Since the server is a full-width blade, it will have the capability to handle 2 dual-port mezzanine cards for up to 40 Gbps I/O per blade. 

Each Cisco UCS 5108 Blade Server Chassis can house up to four B440 M1 servers (maximum 160 per Unified Computing System). 

How Does It Compare to the Competition?
Since I like to talk about all of the major blade server vendors, I thought I’d take a look at how the new Cisco B440 M1 compares to IBM and Dell.  (HP has not yet announced their Intel Xeon 7500 offering.)

Processor Offering
Both Cisco and Dell offer models with 2 – 4 Xeon 7500 CPUs as standard.  They each have variations on speeds – Dell has 9 processor speed offerings; Cisco hasn’t released their speeds and IBM’s BladeCenter HX5 blade server will have 5 processor speed offerings initially.  With all 3 vendors’ blades, however, IBM’s blade server is the only one that is designed to scale from 2 CPUs to 4 CPUs by connecting 2 x HX5 blade servers.  Along with this comes their “FlexNode” technology that enables users to have the 4 processor blade system to split back into 2 x 2 processor systems at specific points during the day.  Although not announced, and purely my speculation, IBM’s design also leads to a possible future capability of connecting 4 x 2 processor HX5’s for an 8-way design.  Since each of the vendors offer up to 4 x Xeon 7500’s, I’m going to give the advantage in this category to IBM.  WINNER: IBM

Memory Capacity
Both IBM and Cisco are offering 32 DIMM slots with their blade solutions, however they are not certifying the use of 16GB DIMMs – only 4GB and 8GB DIMMs, therefore their offering only scales to 256GB of RAM.  Dell claims to offers 512GB DIMM capacity on their the PowerEdge 11G M910 blade server, however that is using 16GB DIMMs.  REalistically, I think the M910 would only be used with 8GB DIMMs, so Dell’s design would equal IBM and Cisco’s.  I’m not sure who has the money to buy 16GB DIMMs, but if they do – WINNER: Dell (or a TIE)

Server Density
As previously mentioned, Cisco’s B440-M1 blade server is a “full-width” blade so 4 will fit into a 6U high UCS5100 chassis.  Theoretically, you could fit 7 x UCS5100 blade chassis into a rack, which would equal a total of 28 x B440-M1’s per 42U rack.Overall, Cisco’s new offering is a nice addition to their existing blade portfolio.  While IBM has some interesting innovation in CPU scalability and Dell appears to have the overall advantage from a server density, Cisco leads the management front. 

Dell’s PowerEdge 11G M910 blade server is a “full-height” blade, so 8 will fit into a 10u high M1000e chassis.  This means that 4 x M1000e chassis would fit into a 42u rack, so 32 x Dell PowerEdge M910 blade servers should fit into a 42u rack.

IBM’s BladeCenter HX5 blade server is a single slot blade server, however to make it a 4 processor blade, it would take up 2 server slots.  The BladeCenter H has 14 server slots, so that makes the IBM solution capable of holding 7 x 4 processor HX5 blade servers per chassis.  Since the chassis is a 9u high chassis, you can only fit 4 into a 42u rack, therefore you would be able to fit a total of 28 IBM HX5 (4 processor) servers into a 42u rack.
WINNER: Dell

Management
The final category I’ll look at is the management.  Both Dell and IBM have management controllers built into their chassis, so management of a lot of chassis as described above in the maximum server / rack scenarios could add some additional burden.  Cisco’s design, however, allows for the management to be performed through the UCS 6100 Fabric Interconnect modules.  In fact, up to 40 chassis could be managed by 1 pair of 6100’s.  There are additional features this design offers, but for the sake of this discussion, I’m calling WINNER: Cisco.

Cisco’s UCS B440 M1 is expected to ship in the June time frame.  Pricing is not yet available.  For more information, please visit Cisco’s UCS web site at http://www.cisco.com/en/US/products/ps10921/index.html.

Announcing IBM eX5 Portfolio and the HX5 Blade Server

UPDATED: 3/2/2010 at 12:58 PM EST
Author’s Note: I’m stretching outside of my “blades” theme today so I can capture the entire eX5 messaging.
 
Finally, all the hype is over.  IBM announced today the next evolution of their “Enterprise x-Architecture”, also known as eX5.  
Why eX5?  Simple:  e=Enterprise X=x-Architecture  5=fifth generation. 

IBM’s Enterprise x-Architecture has been around for quite a while providing unique Scalability, Reliability and Flexibility in the x86 4-socket platforms.  You can check out the details of the eX4 technology here. 

Today’s announcement offered up a few facts:   

a) the existing x3850 and x3950 M2 will be called x3850 and x3950 X5 signifying a trend for IBM to move toward product naming designations that reflect the purpose of the server. 

b) the x3850 and x3950 X5’s will use the Intel Nehalem EX – to be officially announced/released on March 30.  At this time we can expect full details including part numbers, pricing and technical specifications. 

 c) a new 2u high,  2 socket server, the x3690 X5 was also announced.  This is probably the most exciting of the product announcements, as it is based on the Intel Nehalem EX processor but IBM’s innovation is going to enable the x3690 X5 to scale from 2 sockets to 4 sockets – but wait, there’s more.  There will be the ability, called MAX5 to add a memory expansion unit  to the x3690 X5 systems, enabling their system memory to be DOUBLED.d) in addition to the memory drawer, IBM will be shipping packs of solid state disks, called eXFlash that will deliver high performance to replace the limited IOPs of traditional spinning disks.  IBM is touting “significant” increases in performance for local databases with this new bundle of solid state disks.   In fact, according to IBM’s press release, eXFlash technology would eliminate the need for a client to purchase two entry-level servers and 80 JBODs to support a 240,000 IOPs database environment, saving $670,000 in server and storage acquisition costs.   The cool part is, these packs of disks will pop into the hot-swap drive bays of the x3690, x3850 and x3950 X5 servers.

e) IBM also announced a new technology, known as “FlexNode” that offers up physical partitioning capability for servers to move from being a single system to 2 different unique systems and back again. 

 
Blade Specific News
1) IBM will be releasing a new blade server, the BladeCenter HX5 next quarter that will also use the Intel Xeon 7500.  This blade server will scale, like all of the eX5 products, from 2 processors to 4 processors (and theoretically more) and will be ideal for database workloads.  Again, pricing and specs for this product will be released on the official Intel Nehalem EX launch date.  
 

 

  

IBM BladeCenter HX5 Blade Server

 

An observation from the pictures of the HX5 is that it will not have hot-swap drives, like the HS22’s do.  This means there will be internal drives – most like solid state drives (SSDs).  You may recall from my previous rumour post that the lack of hot-swap drives is pretty evident – IBM needed the real estate for the memory.  Unfortunately until memristors become available, blade vendors will need to sacrifice real estate for memory. 

2) As part of the MAX5 technology, IBM will also be launching a memory blade to increase the overall memory on the HX5 blade server.  Expect more details on this in the near future. 

Visit IBM’s website for their Live eX5 Event at 2 p.m. Eastern time at this site:

As more information comes out on the new IBM eX5 portfolio, check back here and I’ll keep you posted.  I’d love to hear your thoughts in the comments below. 

MAX5 Memory Drawer (1U)

 

I find the x3690 X5 to be so interesting and exciting because it could quickly take over the server space that is currently occupied by the HP DL380 and the IBM x3650’s when it comes to virtualization.  We all know that VMware and other hypervisors thrive on memory, however the current 2 socket server design is limited to 12 – 16 memory sockets.  With the IBM System x3690 X5, this limitation can be overcome, as you can simply add on a memory drawer to achieve more memory capacity.
