Physical Disk Capacity
3PAR InForm CLI Administrator’s Manual InForm OS Version 2.3.1
◆ The free space includes the total free initialized and uninitialized spaces available for
use.
10.2.2 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: Fibre Channel (FC), Near Line (NL), and Solid State Drives (SSD).
To display the total capacity for all physical disks of a specific type in an InServ Storage
Server, issue the
showsys -space -devtype FC|NL|SSD command.
10.3 Physical Disk Capacity
The InForm CLI allows you to view capacity for all physical disks in your system, capacity of
physical disks by device type, as well as the capacity for a single physical disk in your system.
10.3.1 Determining Total Physical Disk Capacity
To view the total physical disk capacity of the system, issue the showpd -space command.
The following is an example of the data returned by issuing this 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 10.2.1 Determining Total System Capacity on page 10.3.
NOTE: The Device Speed number does not represent a rotational speed for Solid
State Drives (SSD) 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 in I/O per second, bandwidth,
and the access time.
