Virtual Volumes (VVOL) is a virtual disk management and array integration framework introduced with vSphere 6. VVOLs enables policy-based storage for virtual machines. A datastore is presented backed by raw storage supporting multiple different capabilities, such as snapshotting, replication, deduplication, raid level, performance, and so on. These capabilities are exposed to the vSphere environment. Policies are created and assigned to virtual machines. When a virtual machine is placed on a VVOL datastore, the placement on the array is based on the requirements defined in the policies.
To successfully incorporate VVOLs as part of a vSphere infrastructure design, perform these steps:
