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. Zero-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. How-to: NVIDIA ConnectX driver upgrade on VMware ESXi 6.7/7.0 and aboveĬomponents Overview vSphere Distributed SwitchĪ vSphere Distributed Switch provides centralized management and monitoring of the networking configuration of all hosts that are associated with the switch.ConnectX® Ethernet Driver for VMware® ESXi Server.Remote Direct Memory Access for Virtual Machines.ConnectX® Ethernet Driver for VMware® ESXi Server 4.17.13.1-1vmw.670.6603.This guide assumes the following software and drivers are installed: This document describes how to enable PVRDMA in VMware vSphere 6.5/6.7 with NVIDIA ConnectX network cards.
