US 10,884,974 B2 · Flexible remote direct memory access

Abstract

Apparatus and methods are disclosed herein for remote, direct memory access (RDMA) technology that enables direct memory access from one host computer memory to another host computer memory over a physical or virtual computer network according to a number of different RDMA protocols. In one example, a method includes receiving remote direct memory access (RDMA) packets via a network adapter, deriving a protocol index identifying an RDMA protocol used to encode data for an RDMA transaction associated with the RDMA packets, applying the protocol index to a generate RDMA commands from header information in at least one of the received RDMA packets, and performing an RDMA operation using the RDMA commands.

Dependent claims

An apparatus configured to process transactions for two or more different remote direct memory access (RDMA) protocols, the apparatus comprising:

a network interface;
a processing circuit configured to:
identify an RDMA protocol in which an RDMA packet received via the network interface is encoded, and
detect an RDMA command encoded in the RDMA packet;
a translation memory configured to generate control information by performing a lookup in memory using an address determined based on the identified RDMA protocol, the generated control information being used to translate the RDMA command into a generic RDMA command;
and
the processing circuit being further configured to perform an RDMA operation specified by the RDMA command by performing the generic RDMA command.
