span several physical devices host Types of datastores:  VMFS  Network File System (NFS) host Datastores are used to hold virtual machine files, templates, and ISO images datastore VMware vSphere: Install, Configure, Manage – Revision A 6-9 © 2011 VMware Inc All rights reserved VMFS-5 VMFS-5:  Allows concurrent access to shared storage  Can be dynamically expanded  Uses a 1MB block size, good for storing large virtual disk files  Uses subblock addressing, good for storing small files  Provides on-disk, block-level locking host host VMFS Datastore VMware vSphere: Install, Configure,
