26 HP SureStore E Disk Array XP512/XP48: Owner’s Guide
Disk Array Frames
The disk array frames are where your physical disk drives, the disk groups,
and any dynamic spare disk drives are located. You must have at least one
disk array frame to operate the system, and you may have up to a maximum
of six disk array frames installed on your system. If you have six disk array
frames that are fully populated with disk drives, you will have a maximum
of up to 37 TB.
Available Disk Drives
Your disk array uses 3.5-inch disk drives, and a variety of disk capacities
are available. Ask your HP Service Representative about currently
available disk drives. Any of the disk drives in your disk array frames can
be replaced without disrupting user activity. The disk array automatically
detects and corrects disk errors.
RAID Options
Any of your spare disk drives can back up any other disk drive of the same
capacity, in any disk array, even if the failed disk and the spare disk are in
different array domains, whether you are using RAID0/1 or RAID5 array
groups.
Your disk arrays can be configured with a minimum of one and a maximum
of 16 spare disk drives. See figure 3 (page 27).
