Physical Disks
A physical disk is a hard drive mounted on a drive magazine or module located in drive cages in
HP 3PAR Storage Systems. There are three types of physical disks: Fibre Channel (FC), Near Line
(NL) and Solid State Drives (SSD).
In DC4 drive cages, each drive magazine holds four disks numbered 0 through 3 from the rear
to the front of the magazine. The DC4 drive cages contain a maximum of ten drive magazines for
a maximum of 40 physical disks in each drive cage. See Figure 13 (page 59).

DC3 drive cage contains 16 drive bays and holds up to 16 drive magazine modules for a maximum
of 16 physical disks in each drive cage. See Figure 14 (page 60).
