In this chapter, we will discuss one of the key characteristics of Virtual SAN called Storage Policy Based Management (SPBM).
Traditionally, storage capabilities are tiered and provisioned. Some of the key attributes for tiering are performance, capacity, and availability. The actual implementation of tiers is performed at the hardware level, governed by physical disk capabilities and RAID configuration. VSAN, however, establishes the capabilities at the software layer through policies.
Here we will closely review:
Why is SPBM used?
Attributes that are configurable through SPBM
Understand how SPBM works
Overall, we will discuss the various permutations and combinations of the policy-based management of storage, and how this method modernizes storage provisioning and paves the way for being truly software-defined.
