limited maximum cable lengths. The slow speed Infiniband (1X - SDR) has a max cable length of 20m, but most servers today are using the faster speed Infiniband which has much shorter maximum cable lengths: * 12X - SDR: 10m * 4X - DDR: 10m * 12X - DDR: 7m Of course, optical Inf...

In the case of hypercubes, the same port must be used throughout the fabric to represent the hypercube dimension and match on both ends of the cable. In the case of meshes, the dimension should consistently use the same pair of ports, one port on one end of the cable, and the other ...
In the case of hypercubes, the same port must be used throughout the fabric to represent the hypercube dimension and match on both ends of the cable, or the -O option used to accomplish the alignment. In the case of meshes, the dimension should consistently use the same pair of ports, ...
The connection is established by connecting the HCA2-O LR to the other system's HCA2-O LR or HCA3-O LR port through a 9-micron single mode fiber optic cable. The cable contains one lane with one fiber for transmit and one for receive. The maximum supported length for these connections...

OpenSM now offers nine routing engines: 1. Min Hop Algorithm - based on the minimum hops to each node where the path length is optimized. 2. UPDN Unicast routing algorithm - also based on the minimum hops to each node, but it is constrained to ranking rules. This algorithm should be ch...
