Methods and systems to achieve multi-tenancy in rdma over converged ethernet

A method of performing remote direct memory access (RDMA) between first and second host computers respectively executing first and second virtual machines (VMs) associated with a logical overlay network, the method comprising:

• at a first physical network interface controller (PNIC) of the first host computer:
• receiving an RDMA request that the first VM sends directly to the PNIC;
• encapsulating the request with an encapsulation header associated with the logical overlay network;
• sending the encapsulated RDMA request to a second PNIC of the second host computer to decapsulate the RDMA request and to send the decapsulated RDMA request directly to the second VM executing on the second host computer.

A non-transitory machine readable medium storing a program which when executed by at least one processing unit performs remote direct memory access (RDMA) between first and second host computers respectively executing first and second virtual machines (VMs) associated with a logical overlay network, the program comprising sets of instructions for:

• at a first physical network interface controller (PNIC) of the first host computer:
• receiving an RDMA request that the first VM sends directly to the PNIC;
• encapsulating the request with an encapsulation header associated with the logical overlay network;
• sending the encapsulated RDMA request to a second PNIC of the second host computer to decapsulate the RDMA request and to send the decapsulated RDMA request directly to the second VM executing on the second host computer.
