As an abstraction layer, SPBM abstracts storage services delivered by Virtual Volumes, vSAN, I/O filters, or other storage entities.
Multiple partners and vendors can provide Virtual Volumes, vSAN, 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 entities.
SPBM offers 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.
