Before you create disk groups and volumes, consider the following items:

• The type of volume configurations that are required

• The number of LUNs required for the disk group

• The implications of backup and restore operations on the disk group setup

• The size of databases and logs which depend on the traffic load

• The disk groups and number of disks on each site

  Note:

  For campus clusters, each disk group must contain an equal number of disks on each site.

• Types of volumes required and location of the plex of each volume in the storage array

  Note:

  Each volume should be a mirrored volume with one plex of the volume on Site A's storage array and the other plex of the volume on Site B's storage array.
