The Altix ICE blade platform is an Intel Xeon-based system featuring diskless compute blades and a Hierarchical Management Framework (HMF) for scalability, performance, and resiliency. While the earlier Itanium-based Altix systems ran a single-system image (SSI) Linux kernel on 1024 processors or more using a standard SuSE Linux Enterprise Server (SLES) distribution, the Altix ICE's clustering capabilities uses standard SLES or Red Hat Enterprise Linux distributions and scales to over 51,200 cores on NASA's Pleiades supercomputer.
The Altix ICE 8200LX blade enclosure featured two 4x DDR IB switch blade and one high performing plane, while the Altix ICE 8200EX featured four 4x DDR IB switch blades, and two high performing planes. Both configurations supported either hypercube or fat tree topology, and 16 compute blades within an IRU.
The IP-83 and IP-85 compute blades supported Intel Xeon 5200 or 5400 Series processors, and the IP-95 compute blade supported Intel Xeon 5500 Series processors.
As of fall 2010, the current product is the ICE 8400, based on either Intel Xeon 5500 or 5600 processors or the AMD Opteron 6100 series processors.
