VMware Virtual Volumes (vVols) is an integration and management storage framework that virtualizes external SAN/NAS storage arrays. Instead of managing storage at the traditional Logical Unit Number (LUN) or file-system level, vVols allow VMware vSphere to manage storage with virtual machine granularity.
By shifting the management unit from the data store to the individual VM, vVols enable storage arrays to natively handle data services like snapshots, clones, and replication directly at the application level. Core Architecture Components
To understand how vVols bypass legacy file-system limitations, it relies on five main architectural pieces: vVols 101 | What are vVols? | Lightboard Session
