Networking
Two 256-port Myricom M3-CLOS-ENCL switches, providing a 2+2Gb/s low-latency interconnect for the 512 compute nodes.
Storage
The disk for Big Red's 266TB GPFS volume is hosted on 10 DataDirect Networks S2A 9500 storage controllers, each dual-pathed to 5 SAF 4248 Chassis. Physical disks are aggregated in an 8+1+1 RAID configuration; combined with the dual-pathed controllers, and active/active GPFS storage hosts, multiple levels of redundancy are provided for Big Red's storage space.
Home directories are available via NFSv3 over Gigabit Ethernet.
