The 2U Twin is the latest addition to Supermicro's family of twin servers. 2U Twin introduces an innovative architecture where the devices are hot-swappable to facilitate ease of maintenance, reduce/eliminate down time, while saving power and space by sharing the same chassis and power supplies. The new 2U Twin server features two compute nodes with x16 non-blocking native Gen2 PCI-Express connectivity to the processor and redundant 1400-watt Gold Level (93%+ efficiency) power supplies for maximum availability. Each compute node supports six hot-swap 3.5" SATA drives to deliver unprecedented I/O performance, and an industry leading 6 hot-swap HDD per 1U. Connectivity options include 40Gb/s onboard QDR InfiniBand, and 20Gb/s onboard DDR InfiniBand.
