Storage Policy Based Management (SPBM) is a storage policy framework that provides a single unified control pane across a broad range of data services and storage solutions. The framework helps to align storage with application demands of your virtual machines.

SPBM enables the following mechanisms:

  • Advertisement of storage capabilities and data services that storage arrays and other entities, such as I/O filters, offer.

  • Bidirectional communications between ESXi and vCenter Server on one side, and storage arrays and entities on the other.

  • Virtual machine provisioning based on VM storage policies.

As an abstraction layer, SPBM abstracts storage services delivered by Virtual Volumes, Virtual SAN, I/O filters, or other storage entities. Multiple partners and vendors can provide Virtual Volumes, Virtual SAN, or I/O filters support. Rather than integrating with each individual vendor or type of storage and data service, SPBM provides a universal framework for many types of storage solutions and entities.
