Disk chassis

The disk array chassis house the physical disk drives. Each chassis can contain up to 60 hard disk
drives. The disk array can include up to four disk chassis, two in the primary rack and two more in
the optional second rack.

Disk drives

The primary rack comes with one chassis (R0) which must contain at least four hard disk drives and
can contain up to 60 drives. (A basic version of the HP XP10000 disk array without a disk chassis
is also available.) A second chassis (R1) adds 60 more drives to the primary rack for a total of 120
drives. With a second rack, you can add one more disk chassis for up to 180 drives, or you can add
two more chassis for a maximum of four fully populated disk chassis containing up to 240 physical
disk drives. A variety of disk capacities are available. Ask your HP support representative about
currently available disk drives. The disk array automatically detects and corrects disk errors, and an
HP support representative can replace any of the disk drives without disrupting user activity.
