Best Practices for Running VMware vSphere on Network Attached Storage

Free registration required

Executive Summary

The significant presence of Network Filesystem Storage (NFS) in the datacenter today, as well as the lower cost-per-port for IP based Storage, has lead to many people wanting to deploy virtualization environments with Network Attached Storage (NAS) shared storage resources. As virtualization increases adoption, so does the deployment of VMware ESX servers that leverage NAS. For the purpose of clarity, both NFS and NAS refer to the same type of storage protocol and will be used as terms for the same thing throughout this paper. The capabilities of VMware Virtual Infrastructure 3 (VI3) on NFS are very similar to the VMware vSphere on block-based storage. VMware offers support for almost all features and functions on NFS - as it does for vSphere on SAN.
