Abstract:
1. A host-fabric adapter, comprising: at least one Micro-Engine arranged to establish connections and support data transfer operations, via a switched fabric, in response to work requests that cause instructions in a form of work queue elements “WQEs” posted from a host system for said data transfer operations; a work queue element “WQE” hardware assist “HWA” mechanism arranged to determine the starting address of each work queue element “WQE” based on queue pair (QP) context information needed for said Micro-Engine (ME) to process work requests for said data transfer operations; a transport engine which contains a plurality of work queue pairs (WQPs) in which work requests in a form of work queue elements “WQEs” are posted to describe data transfer operations and locations of data to be moved for processing and/or transportation via said switched fabric; wherein said work queue pairs (WOPs) each comprises: wherein said Micro-Engine and said work queue element “WQE” hardware assist “HWA” mechanism are configured in accordance with the “InfiniBand™ Specification”, and implemented as part of an Application Specific Integrated Circuit (ASIC).
