Storage policies are configured to simplify the provisioning of a virtual machine in the storage. Storage policies ensure that service levels are met for the storage performance, protection, and availability. For Software Defined Storage (SDS), including VSAN and VVOL, these policies are a key component required to determine the virtual machine placement during provisioning and throughout a virtual machine's life cycle.
When incorporating storage policies into a vSphere design, perform the following steps:
Determine the storage services and capabilities required by virtual machine workloads:
What data protection service will be required for virtual machines?
Are capabilities such as encryption at rest, deduplication, or compression required?
Are different tiers of storage required?
Identify how storage array capabilities will be discovered:
Is a VASA provider available for providing awareness about storage capabilities?
Will tags be used...
