InfiniBand Boards Drive VITA 41

SBS Technologies' 10-Gbit/s InfiniBand switch and single-board computer (SBC) plug into a standard 6U VME VITA 41 switch-fabric system. The IB4X-V41 is a 24-port 4× InfiniBand switch that uses a single Mellanox InfiniScale III switch chip with an aggregate bandwidth of 480 Gbits/s. The VXS1 VITA 41 SBC is driven by a 1-GHz Freescale MPC7447A G4 PowerPC. It contains a built-in, Mellanox MT23108 4× InifiniBand host bus adapter (HBA). The SBC supports the 320-Mbyte/s 2eSST backplane protocol. The board also has a Marvell MV64460 Discovery III system controller, 512 Mbytes of SDRAM, 256 Mbytes of flash, 32 kbytes of NVRAM, dual serial ports, parallel I/O, and dual Gigabit Ethernet interfaces. Both come in conduction- and convection-cooled models. The convection-cooled InfiniBand switch costs $7500. The SBC goes for $5800.
