------------------------------------------------
10Uラックに、独自 3Dトーラスで 32bit版 Atom 512個 (512コア) 搭載した
SeaMicro SM10000シリーズに、64bit版 Atom搭載モデルが発表されました：
"SeaMicro Now Shipping the World's Most Energy Efficient x86 Server
with New 64-bit Intel Atom N570 Processor"
February 28, 2011
http://www.seamicro.com/?q=node/110
搭載される Atom N570 dual-core (1.66GHz) はまだ正式発表されていない
ようですが、既存の SM10000 (32bit版) からの大きな違いは
512 32 bit Sigle-core (1.6GHz) Z530 = 512 Core
=> 256 64 bit Dual-core (1.66GHz) N570 = 512 Core
=> VT-x and 64 bit OS support (Xen, KVM, Hyper-V等に対応)
1 Terabyte DRAM (同じ)
1.28 Terabit per second fabric (同じ)
Average power consumption < 2 KW (同じ)
その他仮想化 I/O、筐体等も同じ。

※総コア数は変わらないので、Atomソケット数は半分になります。
1ソケットあたりのメモリは、2GBから 4GBに増えます (総容量は同じ)
興味深い記述が
"What SeaMicro developed - and what makes the SM10000 server unique
- is an ASIC chip that virtualizes disk access and Ethernet
networking for each of the Atom servers. The ASIC also implements
a 3D torus interconnect between all of the 64 server boards nodes
in the chassis, which delivers 1.28 Tb/sec of aggregate bandwidth
across the cores and boards in the box. The SM10000 also has a
little something called Dynamic Compute Allocation Technology, or
DCAT, which is a home-grown field programmable gate array (FPGA)
that does load balancing across the cores and boards."
"The load balancing electronics are hooked into the SM10000's
system management tools to allow for pools of servers to be grouped
together and managed as a single object and to provide guaranteed
performance levels for groups of processors, disk, memory, and
fabric."
......
"The chassis has different network modules, which offer 8 to 64
Gigabit Ethernet uplinks or 2 to 16 10 Gigabit Ethernet uplinks per
chassis. The FPGAs implementing the load balancer and terminal
software as well as the switching software are in the chassis, not
on the server cards. The chassis has room for 64 SATA or SSD disks
as well, which are on the front of the box."
....
"Feldman is not going to tell us how many boxes he has shipped or
how much money the initial systems have generated, of course. But
he did confirm that companies such as Skype. France Telecom,
China Netcom Broadband, and Rogers Communications, as well as
Mozilla and Oak Ridge National Laboratories, had the SeaMicro
machines in production."
