The HP StoreOnce 4500 Backup system consists of a head server unit with 12 x 2TB disks. The
disks in the first two slots are used for the operating system and filesystem; the remaining disks are
used for data storage. It supports connection of up to three expansion shelves (Capacity Upgrade
Kits); storage must be expanded when an additional shelf is added to the base configuration. The
expansion shelf has either 12 x 2 TB disks or 12 x 4 TB disks.
