HP 3PAR Command Line Interface Administrator's Manual: HP 3PAR OS 3.1.2 (QR482-96525, September 2013)

• Unmapped volumes.
• System space, which includes administration volumes, log files, and physical disk system data,
as well as used and unused spare space.
• The free space includes the total free initialized and uninitialized spaces available for use.
Determining System Capacity by Physical Disk Type
You can display the total capacity for all physical disks of a specific type. There are three types
of physical disks: FC, NL, and SSDs.
To display the total capacity for all physical disks of a specific type in a system, issue the showsys
-space -devtype FC|NL|SSD command.
NOTE: The output of the showsys -space -devtype FC|NL|SSD command is displayed
in the same format as the showsys -space command output example in “Determining Total
System Capacity” (page 105).
Physical Disk Capacity
The HP 3PAR CLI allows you to view capacity for all physical disks in your system, capacity of
physical disks by device type, and the capacity for a single physical disk in your system.
NOTE: The Device Speed number does not represent a rotational speed for SSDs without spinning
media. It is meant as a rough estimation of the performance difference between the drive and the
other drives in the system. For FC and NL drives, the number corresponds to both a performance
measure and actual rotational speed. For an SSD, the number is to be treated as a relative
performance benchmark that takes into account I/O per second, bandwidth, and the access time.
Determining Total Physical Disk Capacity
To view the total physical disk capacity of the system, issue the showpd -spacecommand. The
following is an example of the data returned by issuing this command:
cli% showpd -space
