Launched in April, the 1, 000-node network is anchored by two redundant 3Com CoreBuilder 9000 switches interconnected by dual 1Gbps Gigabit Ethernet-trunked connections.
Each node has 2-8 Xeon 5650 processors providing 6-48 coes and up to 768 GB of RAM, 1.3 TB of Fusion-io ioDrive PCIe flash cards and a mid-layer of up to 1.2 TB of Intel SSD storage.
