  • Co-existence of routable and non-routable RDMA solutions on the same network interface
    Patent number: 10044616
    Abstract: An example method for simultaneously supporting, on a single VIC adapter (i.e. on a single network interface), RDMA transport according to multiple RoCE versions is disclosed. The method includes providing the VIC adapter with an indication of a RoCE version used for a particular RDMA connection between two compute nodes identified by a certain QP identifier, and then automatically configuring Egress (EG) packet classifier and flow table of the VIC adapter to encapsulate outgoing RDMA commands and automatically configuring Ingress (IG) packet classifier and flow table of the VIC adapter to decapsulate incoming RoCE packets for that RDMA connection according to the indicated RoCE version. Automatic encapsulation and decapsulation according to any one of the multiple RoCE versions that may be used for a particular RDMA connection, i.e. on a per-QP basis, advantageously allows co-existence of routable (i.e. RoCEv2) and non-routable (i.e. RoCEv1) RDMA solutions on a single network interface.

  • Flexible remote direct memory access resource configuration in a network environment
    Patent number: 9548890
    Abstract: An example method for flexible remote direct memory access resource configuration in a network environment is provided and includes determining whether sufficient remote direct memory access (RDMA) resources are available in a network environment to satisfy a request for RDMA resources, inserting the requested RDMA resources into a network profile, associating the network profile with a network interface endpoint in the network, and communicating the network profile over the network to a virtual interface card (VIC) adapter that processes RDMA packets, the VIC adapter configuring the requested RDMA resources in the VIC adapter's hardware and the requested RDMA resources being mapped to a host memory for use by the network interface endpoint. In specific embodiments, the VIC adapter allocates and identifies a region in local memory for managing the requested RDMA resources and reserved for the network interface endpoint.
