FDR10 is a non-standard InfiniBand data rate, where each lane of a 4X port runs a bit rate of 10.3125 Gbit/s with a 64b/66b encoding, resulting in an effective bandwidth of 40 Gbit/s. FDR10 supports 20% more bandwidth over QDR due to better encoding rate.
InfiniBand FDR and FDR10 Overview [...] FDR, standard InfiniBand data rate, where each lane of a 4X port runs a bit rate of 14.0625 Gbit/s with a 64b/66b encoding, resulting in an effective bandwidth of 54.54 Gbit/s. The FDR physical layer is an IBTA specified physical layer using different block types, deskew mechanism and framing rules. The SX6518 switch also supports FDR10, a non-standard InfiniBand data rate, where each lane of a 4X port runs a bit rate of 10.3125 Gbit/s with a 64b/66b encoding, resulting in an effective bandwidth of 40 Gbit/s.
InfiniBand technology is now found on 205 systems, down from 235 systems, and is now the second most-used internal system interconnect technology. Gigabit Ethernet has risen to 218 systems up from 182 systems, in large part thanks to 176 systems now using 10G interfaces.
