System and method to provide path records derived from ARP responses and peer-to-peer negotiation based on homogeneous fabric attribute in a high performance computing environment

摘要

Systems and methods for InfiniBand fabric optimizations to minimize SA access and startup failover times. Based on the combination of path record parameters defined with values from the Homogeneous Fabric/Subnet flag (or configuration parameter), as well as the GID and SLID information defined by IPoIB ARP requests and responses, there is no additional need for SA requests to obtain path records or path related information in general.
