To work with vVols, you must make sure that your storage and vSphere environment are set up correctly.

Prepare Storage System for vVols

To prepare your storage system environment for vVols, follow these guidelines. For additional information, contact your storage vendor.

  • The storage system or storage array that you use must support vVols and integrate with the vSphere components through vSphere APIs for Storage Awareness (VASA). The storage array must support thin provisioning and snapshotting.
  • The vVols storage provider must be deployed.
  • The following components must be configured on the storage side:

Prepare vSphere Environment

  • Make sure to follow appropriate setup guidelines for the type of storage you use, Fibre Channel, FCoE, iSCSI, or NFS. If necessary, install and configure storage adapters on your ESXi hosts.
    • If you use iSCSI, activate the software iSCSI adapters on your ESXi hosts. Configure Dynamic Discovery and enter the IP address of your vVols storage system. See Configure the Software iSCSI Adapter.
  • Synchronize all components in the storage array with vCenter Server and all ESXi hosts. Use Network Time Protocol (NTP) to do this synchronization.
