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:
  •
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.
  •
Disaster Recovery—Application of synchronous or asynchronous data replication technologies 
from source to target storage system for backup and recovery from secondary facilities for 
mission-critical applications.
In the context of FlexPod and NetApp storage arrays, the following links provide more information on 
tiering, replication, backup, and DR technologies:
