Tiered Services
With respect to storage resources, the following methods may be utilized to differentiate storage services
to meet tenant application requirements and insure service continuity:
to meet tenant application requirements and insure service continuity:
•
Storage Tiering—A mixture of various types of storage drives (SATA, SAS, flash) with differing
capacity, performance and reliability characteristics are applied to meet application IOPs
requirements.

Storage Protection—Storage protection options in the form of datastore snapshots to provide point
in time file copies, or cloning for data volume or dataset replication.
