petabyte
A unit of storage capacity that is the equivalent of 2
bytes or 1,024 terabytes.
physical disk A disk drive mounted in a drive enclosure that communicates with a controller
pair through the device-side Fibre Channel loops. A physical disk is hardware
with embedded software, as opposed to a virtual disk, which is constructed by
the controllers. Only the controllers can communicate directly with the physical
disks.
The physical disks, in aggregate, are called the array and constitute the storage
pool from which the controllers create virtual disks.
