Cell fabric hardware acceleration

摘要

An aspect includes providing direct communication between a server and a network switch in a cell-based fabric. A host channel adapter of a cell fabric hardware accelerator is configured to provide the server with direct access to memory within the network switch. A plurality of data packets having a fixed size is received at the host channel adapter from the server. The host channel adapter is coupled to a bus of the server. A direct transmission is performed from the cell fabric hardware accelerator to the memory within the network switch on an interconnect bus to write the data packets directly into the memory.

1. A cell fabric hardware accelerator for providing direct communication between a server and a network switch in a cell-based fabric, the cell fabric hardware accelerator comprising:
a host interface configured to communicate with the server on a bus; and a host channel adapter coupled to the host interface, the host channel adapter configured to provide the server with direct access to memory within the network switch and perform a method comprising: receiving a plurality of data packets having a fixed size at the host channel adapter from the server; and performing a direct transmission from the cell fabric hardware accelerator to the memory within the network switch on an interconnect bus to write the data packets directly into the memory via a memory access port of the network switch using a remote direct memory access (RDMA) operation, the memory access port providing line buffering and format adjustment between the interconnect bus and the memory, and the memory access port is independent of network ports of the network switch that send packets to a plurality of other network switches using variable packet sizes.
