Description Column
Location of the disk in the format in Cage:Magazine:Disk format. Position
Indicates whether a physical disk is a Fast Class (FC), Nearline (NL), or Solid
State (SSD) drive. Device Type
The protocol used by the device, e.g., FC or Serial Attached SCSI (SAS). Device Protocol
Speed of the specified disk. Device RPM
NOTE: The Device RPM number does not represent a rotational speed for the drives without spinning media (SSD).
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 drive, the number is to be treated as relative performance benchmark that takes into account in I/O per second,
bandwidth, and the access time.
State of the disk as identified by the kernel. State
Total amount of usable storage for this disk drive. Total Capacity
Amount of free space (in GiB) in the disk drive, regardless of initialized or not. Free Capacity
Amount of storage remaining (in GiB) for use on the disk drive. Allocated Capacity
Amount of storage (as a percentage) consumed by the disk drive. Allocated Percentage
Location of the primary initiator port to which the disk is attached, in
Node:Slot:Port format. Port A
Location of the secondary initiator port to which the disk is attached, in
Node:Slot:Port format. Port B
The name of the disk manufacturer. Manufacturer
Media type of as SSD device, such as Magnetic or Single-Level Cell (MLC or
SLC). Media Type
The estimated remaining life of an SSD, as a percentage. The threshold limit is
95%. If the remaining life exceeds the threshold (that is, 5% or less life remaining),
the bar will change from green to red. Life Remaining
