To use PVRDMA in vSphere 6.5/6.7, your environment must meet several configuration requirements.
VMWARE VSPHERE 6.5 DISTRIBUTED SWITCH DRIVERName Driver State MTU Speed Paired Uplink Description The below table provides details of ESXi server names and their network configuration: Moreover, the cache of the remote CPU will not be filled with the accessed memory content. The remote memory server will be read without any intervention from the remote process (or processor). Kernel bypass - Allows applications to perform data transfers directly from the user-space without the kernel involvement.ĬPU Offload - Allows applications to access a remote memory without consuming any CPU time on the remote server. Data is sent and received directly to the buffers without being copied between the network layers. VMWARE VSPHERE 6.5 DISTRIBUTED SWITCH SOFTWAREZero-copy - Allows applications to perform data transfers without involving the network software stack. Remote Direct Memory Access (RDMA) - is the ability of accessing memory (read, write) on a remote machine without interrupting the CPU(s) processes on the system. Paravirtual RDMA (PVRDMA)ĭirect Memory Access (DMA) - A device's capability to access host memory directly, without the intervention of the CPU. You must set up a distributed switch on a vCenter Server system, and its settings will be propagated to all hosts that are associated with the switch. VMWARE VSPHERE 6.5 DISTRIBUTED SWITCH UPGRADE
