Updated 5/24/2010 – I’ve received some comments about expandability and I’ve received a correction about the speed of Dell’s memory, so I’ve updated this post.You’ll find the corrections / additions below in GREEN.
Since I’ve received a lot of comments from my post on the Dell FlexMem Bridge technology, I thought I would do an unbiased comparison between Dell’s FlexMem Bridge technology (via the PowerEdge 11G M910 blade server) vs IBM’s MAX5 + HX5 blade server offering. In summary both offerings provide the Intel Xeon 7500 CPU plus the ability to add “extended memory” offering value for virtualization, databases and any other workloads that benefit from large amounts of memory.

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 BladeCenterHX5next 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.

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.
Industry Opinions
Check out this analyst’s view of the IBM eX5 announcement here (pdf).
Here’s what VMware’s CTO, Stephen Herrod, has to say about IBM eX5:
Okay, I can’t hold back any longer – I have more rumours. The next 45 days is going to be an EXTREMELY busy month with Intel announcing their Westmere EP processor, the predecessor to the Nehalem EP CPU and with the announcement of the Nehalem EX CPU, the predecessor to the Xeon 7400 CPU. I’ll post more details on these processors in the future, as it becomes available, but for now, I want to talk on some additional rumours that I’m hearing from IBM. As I’ve mentioned in my previous rumour post: this is purely speculation, I have no definitive information from IBM so this may be false info. That being said, here we go:
Rumour #1: As I previously posted, IBM has announced they will have a blade server based on their eX5 architecture – the next generation of their eX4 architecture found in their IBM System x3850 M2 and x3950M2. I’ve posted what I think this new blade server will look like (you can see it here) and I had previously speculated that the server would be called HS43 – however it appears that IBM may be changing their nomenclature for this class of blade to “HX5“. I can see this happening – it’s a blend of “HS” and “eX5”. It isa new class of blade server, so it makes sense. I like the HX5 blade server name, although if you Google HX5 right now, you’ll get a lot of details about the Sony CyberShot DSC-HX5 digital camera. (Maybe IBM should re-consider using HS43 instead of HX5 to avoid any lawsuits.) It also makes it very clear that it is part of their eX5 architecture, so we’ll see if it gets announced that way.
Speaking of announcements…
Rumour #2: While it is clear that Intel is waiting until March (31, I think) to announce the Nehalem EX and Westmere EP processors, I’m hearing rumours that IBM will be announcing their product offerings around the new Intel processors on March 2, 2010 in Toronto. It will be interesting to see if this happens so soon (4 weeks away) but when it does, I’ll be sure to give you all the details!
That’s all I can talk about for now as “rumours”. I have more information on another IBM announcement that I can not talk about, but come back to my site on Feb. 9 and you’ll find out what that new announcement is.
