Abstract: A method for providing multi-tenancy support for RDMA in a system that includes a plurality of physical hosts. Each each physical host hosts a set of data compute nodes (DCNs). The method, at an RDMA protocol stack of the first host, receives a packet that includes a request from a first DCN hosted on a first host for RDMA data transfer from a second DCN hosted on a second host. The method sends a set of parameters of an overlay network that are associated with the first DCN to an RDMA physical network interface controller of the first host. The set of parameters are used by the RDMA physical NIC to encapsulate the packet with an RDMA data transfer header and an overlay network header by using the set of parameters of the overlay network to transfer the encapsulated packet to the second physical host using the overlay network.

Abstract: Some embodiments provide a method of providing distributed storage services to a host computer from a network interface card (NIC) of the host computer. At the NIC, the method accesses a set of one or more external storages operating outside of the host computer through a shared port of the NIC that is not only used to access the set of external storages but also for forwarding packets not related to an external storage. In some embodiments, the method accesses the external storage set by using a network fabric storage driver that employs a network fabric storage protocol to access the external storage set. The method presents the external storage as a local storage of the host computer to a set of programs executing on the host computer. In some embodiments, the method presents the local storage by using a storage emulation layer on the NIC to create a local storage construct that presents the set of external storages as a local storage of the host computer.

Abstract: A method for providing multi-tenancy support for RDMA in a system that includes a plurality of physical hosts. Each each physical host hosts a set of data compute nodes (DCNs). The method, at an RDMA protocol stack of the first host, receives a packet that includes a request from a first DCN hosted on a first host for RDMA data transfer from a second DCN hosted on a second host. The method sends a set of parameters of an overlay network that are associated with the first DCN to an RDMA physical network interface controller of the first host. The set of parameters are used by the RDMA physical NIC to encapsulate the packet with an RDMA data transfer header and an overlay network header by using the set of parameters of the overlay network to transfer the encapsulated packet to the second physical host using the overlay network.

Abstract: A method for offloading packet encapsulation for an overlay network is provided. The method, at a virtualization software of a host, sends a mapping table of the overlay network to a physical network interface controller (NIC) associated with the host. The mapping table maps the identification of each of a set of virtual machine (VM) of a tenant on the host to an identification of a tunnel on the overlay network. The method, at the virtualization software, receives a packet from a VM of the tenant. The method sends the packet to the physical NIC. The method, at the physical NIC, encapsulates the packet for transmission over the overlay network by using the mapping table. The method of claim also tags the packet by the virtualization software as a packet that requires encapsulation for transmission in the overlay network prior to sending the packet to the physical NIC.

Abstract: An approach for a dynamic provisioning of multiple RSS engines is provided. In an embodiment, a method comprises monitoring a CPU usage of hardware queues implemented in a plurality of RSS pools, and determining whether a CPU usage of any hardware queue, implemented in a particular RSS pool of the plurality of RSS pools, has increased above a threshold value. In response to determining that a CPU usage of a particular hardware queue, implemented in the particular RSS pool, has increased above the threshold value, it is determined whether the particular RSS pool includes an unused hardware queue (a queue with light CPU usage). If such an unused hardware queue is presented, then an indirection table that is associated with the particular RSS pool is modified to remap one or more data flows from the particular hardware queue to the unused hardware queue.
