vVols is an integration and management framework for external storage introduced with vSphere 6. vVols in Purity delivers many benefits for virtualized environments. Effortlessly streamline storage operations such as Pure's efficient snapshots and replication through Storage Policy Based Management at per-VM level granularity; automate compliance checking of assigned data services; rapid deleted volume recovery; and flexibility to move VMs and their data as needed.
VMware has identified a critical issue when using vVols with ESXi 6.7 U2. Should vSphere Replication be in use with vVols hosts will PSOD. If using vSphere Replication in the ESXi environment using vVols, please run either ESXi 6.5 U3, 6.7 U1 or ESXi 6.7 U3. Refer to VMware's KB on the issue found here.
