Restrictions and guidelines for RAID configuration
•
As a best practice, install drives that do not contain RAID information.
•
For efficient use of storage, use drives that have the same capacity to build a RAID. If the
drives have different capacities, the lowest capacity is used across all drives in the RAID.
•
If one drive is used by several logical drives, RAID performance might be affected and
maintenance complexities will increase.
