VMware designed the vVol architecture to mitigate the limitations of the VMFS-based storage paradigm while retaining the benefits, and merging them with the remaining advantages of Raw Device Mappings.
VMware’s vVol architecture consists of the following components:
-
Management Plane (section titled The FlashArray VASA Provider)
- Implements the APIs that VMware uses to manage the array. Each supported array requires a vSphere API for Storage Awareness (VASA) provider, implemented by the array vendor.
-
Data Plane (section titled vVol Binding)
- Provisions vVols to ESXi hosts
-
Policy Plane (section titled Storage Policy Based Management)
- Simplifies and automates the creation and configuration of vVols.
