IBM Intelligent Cluster

The solution was formerly known as the IBM eServer Cluster 1300 (or e1300) based on then-current Pentium III processors, which was introduced in November 2001.

[6] Roughly twice a year the solution components were updated to include the then-current products from IBM and other vendors.

The system could comprise traditional rack-optimized nodes, as well as IBM BladeCenter, Flex System or iDataPlex blade nodes, or another rack-mounted servers[7][8] with processor choices between x86-based (Intel Xeon and AMD Opteron) or uncommon Power-based processors options (only for blade servers),[7] along with integrated storage and switches to provide a turnkey Linux or Microsoft cluster environment.

These platform also supports the water-cooling module options (Heat Exchange Doors) for some rack towers designs.

Operating system choices were officially limited to Enterprise Linux distributions from Red Hat and SUSE and to Microsoft Windows HPC Server 2008.
