Working with Storage DRS
Storage DRS (SDRS) builds on the functionality of Storage I/O Control and Storage vMotion, providing the ability to perform automated balancing of storage utilization. SDRS can perform this automated balancing not only based on storage capacity utilization, but also based on I/O load balancing.
Like DRS, SDRS is built on some closely related concepts and topics:
- Just as DRS uses clusters as a collection of hosts on which to act, SDRS uses datastore clusters as a collection of datastores on which it acts.
- Just as DRS can perform both initial placement and manual and ongoing balancing, SDRS also performs initial placement of VMDKs and ongoing balancing of VMDKs—as well as related VM files. The initial placement functionality of SDRS is especially appealing because it helps simplify the VM provisioning process for vSphere administrators.
- Just as DRS offers affinity and anti-affinity rules to influence placement recommendations, SDRS offers VMDK affinity and...
