To support the differing security, backup, performance, and data sharing needs of your users, you can group the physical data storage resources on your storage system into one or more aggregates. You can then design and configure these aggregates to provide the appropriate level of performance and redundancy.
Each aggregate has its own RAID configuration, plex structure, and set of assigned drives or array LUNs. The aggregate provides storage, based on its configuration, to its associated FlexVol volumes or Infinite Volume.
Aggregates have the following characteristics:
The cluster administrator can assign one or more aggregates to a Storage Virtual Machine (SVM), in which case you can use only those aggregates to contain volumes for that SVM.
For information about best practices for working with aggregates, see Technical Report 3437: Storage Subsystem Resiliency Guide.
