SGI is updating its Altix ICE blade
servers with the latest x86 processors from both Intel and Advanced Micro
Devices and a bulked-up InfiniBand network designed to increase scalability.
SGI’s Altix ICE 8400,
announced May 5 and aimed at the HPC (high-performance
computing) space, can scale as high as 65,536 nodes, and can be powered by
either Intel’s six-core Xeon 5600 “Westmere EP” processors or AMD’s
eight- to 12-core Opteron 6100 “Magny-Cours” chips.
Other improvements over other generations of the 3-year-old
product line include a Quad Data Rate InfiniBand that, combined with SGI’s
integrated backplane, offers three times the link-to-node bandwidth of other
InfiniBand clusters.
The Altix ICE supports up to 128 processors—or 1,536 cores—in
each cabinet. In addition, the system can support high-end CPUs that run 130
watts, the hottest running of the Intel processors. The systems also support
three ConnectX-2 InfiniBand HCA compute
blade configurations from Mellanox.
Because of its x86 architecture, users can easily deploy any
kinds of applications—commercial, open-source or custom—on such operating
systems as Novell SUSE or Red Hat Linux. The open nature of the Altix ICE
systems is key, according to SGI CEO
Mark Barrenechea.
"Altix ICE 8400 eliminates the need for proprietary
processors and operating systems," Barrenechea said in a statement.
"Customers will be able to deploy the world's largest and fastest clusters
on open and standard technologies by using our latest generation of Altix ICE
solutions."
The 8400 is the fourth generation of the HPC
blade system.
The Altix ICE 8400 comes in five models. The IP101, IP103 and
IP105 all come with Intel’s Xeon 5600 series chips, with connectives for
single-plane and dual-plane configurations.
Two other models, the IP106 and IP110, are powered by AMD’s
Opteron 6100 chips, both for dual-plane configurations.
The Intel-based models are available immediately; the AMD-based
models will be available in the third quarter.
