Array Groups

Array groups are collections of up to four arrays that are managed as a single entity. Grouped arrays allow you to aggregate for increased performance and capacity. For iSCSI arrays, grouping makes multi-array storage pools possible.

NOTE: If you have configured synchronous replication and want to enable the Automatic Switchover feature, the array group can only consist of two arrays. For more information, see Synchronous Replication.

Once an array is initialized, it becomes a group of one. When a group contains only one array, the GUI simplifies the presentation by hiding some group and pool features that apply only to multi-array groups.

If other arrays are added to this group, that first array becomes the group leader. You can then access the added arrays using the management IP address of the group leader.
