using a standard SuSE Linux Enterprise Server (SLES) distribution, the Altix ICE's clustering capabilities use standard SLES or Red Hat Enterprise Linux distributions and scale to over 51,200 cores on NASA's Pleiades supercomputer. The Altix ICE 8200LX blade enclosure features two 4x DDR IB switch blade and one high-performing plane, and the Altix ICE 8200EX features four 4x DDR IB switch blades, and two high-performing planes. Both configurations support either hypercube or fat tree topology, and 16 compute blades within an IRU. The IP-83 and IP-85 compute blades support Intel Xeon 5200 or 5400 Series processors, and the IP-95 compute blade support Intel Xeon 5500 Series processors. In November 2011 the ICE 8400 is based on either Intel Xeon 5500 or 5600 processors or the AMD Opteron 6100 series processors. , these use the Xeon Phi coprocessors. Altix UV The Altix UV supercomputer architecture was announced in November 2009. Codenamed Ultraviolet during development, the Altix UV combines a development of the NUMAlink interconnect used in the Altix 4000 (NUMAlink 5) with quad-, six- or eight-core "Nehalem-EX" Intel Xeon 7500 processors. Altix UV systems run either SuSE Linux Enterprise Server or Red Hat Enterprise Linux, and scale from 32 to 2,048 cores with support for up to 16 Terabytes (TB) of shared memory in a single system image. In 2010 and 2011, SGI retired the Altix name for new servers produced by the company. Altix UV and Altix ICE have been shortened to "SGI UV" and "SGI ICE," while the Altix XE line is named "Rackable." References Silicon Graphics, Inc. (June 12, 2007).
