Name Type Description
storage-tier string
● Archive: The disk group is in the lowest storage tier, which uses midline
spinning SAS disks (<10k RPM, high capacity).
● Performance: The disk group is in the highest storage tier, which uses SSDs
(high speed).
● Read Cache: The disk is an SSD providing high-speed read cache for a
storage pool.
● Standard: The disk group is in the storage tier that uses enterprise-class
spinning SAS disks (10k/15k RPM, higher capacity).
storage-tier-numeric uint32 Numeric equivalents for storage-tier values.
● 0: N/A
● 1: Performance
● 2: Standard
● 4: Archive

total-pages uint32 For a virtual disk group, the total number of 4 MB pages it contains. For a linear
disk group, 0.
allocated-pages uint32 For a virtual pool, the number of 4 MB pages that are currently in use. For a linear
pool, 0.
available-pages uint32 For a virtual pool, the number of 4 MB pages that are still available to be
allocated. For a linear pool, 0.
pool-percentage uint8 The percentage of pool capacity that the disk group occupies.
