VMware VMDirectPath I/O (PCI passthrough) enables direct assignment of hardware PCI functions such as NVMe solid-state drives to a virtual machine. This gives the VM access to the PCI functions with minimal intervention from the ESXi host, potentially improving performance.

In this paper, we describe how to configure NVMe SSDs passthrough as PCI devices to VMs on Lenovo® ThinkSystem™ servers. We provide step-by-step instructions using VMware ESXi 7.0 U1.

This paper is intended for IT specialists and IT managers who want to learn more about NVMe SSDs passthrough.
