Standard servers use TCP/IP, which incurs CPU interrupts. The X8-2 uses (RDMA over Converged Ethernet). This allows one server to write directly into the memory of another server with zero CPU overhead. The datasheet lists this as “Dual-port 100 Gb Ethernet.” : Includes twelve 14 TB 7,200 RPM disks and four 6

: Uses a 40 Gb/second (QDR) InfiniBand network to connect all servers and storage components. This allows one server to write directly into
