Crayの 46ノード Intel Core i7ベース Microserver契約発表 (2011/06/30) から

先ずは契約プレスリリース：
"X-ES Develops 46 CPU-Node Data Center Blade for Cray targeting
Intel Core i7 Processors"
Jun 30th, 2011
"Under contract to Cray Inc., Extreme Engineering Solutions, Inc.
(X-ES) developed and delivered a prototype next-generation data
center blade consisting of forty-six Intel Core i7 processor cards.
Cray's Custom Engineering group designed the system infrastructure
that combines super efficient power delivery, high-density packaging,
and innovative cooling technologies. With the design in place,
Cray turned to Extreme Engineering Solutions, Inc. (X-ES) to develop
the blade hardware."

"Cray stuffs 46 mobile Intel chips into microserver"
Packed, racked, and ruggedized
6th July 2011, The Register
.....
"With the blades installed, it is about four-inches high outside of
the chassis. That is just about the right size to fit into a standard
4U chassis with room left over for chassis power distribution."
"The unnamed 46-node Core i7 microserver from Cray and X-ES"
"The server nodes, which plug into PCI-Express 2.0 peripheral slots,
use that PCI bus to power the nodes and to provide links to
a Gigabit Ethernet switch that is embedded in the system and that
provides interconnectivity for the server nodes. There are two rows of
blade servers in the system, and the board is laid out with two rows of
12 blades in the front and two rows of 11 blades in the back."
※奥が 11 bladesなのは外部 PCIeスロット用 (10G/InfiniBand?) だと思います。
※Node間 Gigabit Ethernetスイッチは真ん中の 2枚？
Arrandale, not Sandy Bridge
"The feeds and speeds of the server nodes are not available, but
our source tells us that the boards are based on Intel's "Arrandale"
Core i7 processors, not the latest "Sandy Bridge" variants, and that
these processors are not put into standard sockets where they can be
swapped out but rather directly mounted on the board.
"Ditto for the DDR3 main memory, which is also soldered right to the
board and which has ECC data protection. By doing this, X-ES can keep
a very compact design and better control airflow around the components
to cool them."
Interwebs love
"At four inches high, the 46-node microserver created by Cray and X-ES
could easily fit in a 2.5U form factor, cramming 92 cores in that
space and maybe 184GB of memory."
※ 4GB/node (2 Core)
"We estimate that the microserver chassis would draw 1,300 to 1,400 peak
watts of juice if the 25 watt Arrandale parts are used, and would run
under normal to heavy load at under 1,000 watts."
ふと思ったけど、ファンの配置に工夫がいるのでは、
CPUノード間対流を考慮したら、試作の 2列じゃなく半分での 4列になりそう。
でもそうなるとバックプレーンの再設計となるから、ファン配置で対処かな？

Cray's Custom Engineering groupに関するプレスリリース
"Cray's Custom Engineering Group to Work With Microsoft Research on
Cloud Computing"
Mar 02, 2010
"... today announced its custom engineering group will work with
Microsoft Research to explore and prototype a system that could provide
a glimpse into the future of cloud computing infrastructure.
The initiative represents the custom engineering group's first
breakthrough into the commercial market.
The objective of the technology development initiative is to design
a supercomputing architecture that dramatically lowers the total cost
of ownership for cloud computing data centers." ...
.....
""Our goal is to work with partners such as Cray to accelerate changes
in system designs for next-generation data centers," said Christian Belady,
Director of Hardware Architecture in Microsoft's Extreme Computing Group.
"Ultimately, our mission is to dramatically reduce total cost of ownership
while significantly boosting performance.""

"... This week I begin tackling these projects within the Microsoft
Research group in team called the Extreme Computing Group.
This is exciting in itself, but what really gets me "charged" is
the opportunity I have now to work between my former group Global
Foundation Services (that drives the current Microsoft cloud
infrastructure) and my new group Microsoft Research (MSR). Taking
the best practices from what we have learned with our current and future
Gen 4 data centers and combining them with the resources of one of
the best research organizations in the world (MSR), I am convinced
that many new and exciting things will come."
