Eos is an IBM "iDataPlex" commodity cluster with nodes based on Intel's 64-bit Nehalem & Westmere processor. The cluster is composed of 6 head nodes, 4 storage nodes, and 362 compute nodes. The storage and compute nodes have 24 GB of DDR3 1333 MHz memory while the head nodes have 48 GB of DDR3 1066 MHz memory. A Voltaire Grid Director 4700 QDR IB switch provides the core switching infrastructure.
