Table 81. pool-statistics properties (continued)
Name Type Description
pages-alloc-per-hour uint32 The rate, in pages per hour, at which pages are allocated to volumes in the pool
because they need more space to store data.
pages-dealloc-per-minute uint32 The rate, in pages per minute, at which pages are deallocated from volumes in
the pool because they no longer need the space to store data.
pages-dealloc-per-hour uint32 The rate, in pages per hour, at which pages are deallocated from volumes in the
pool because they no longer need the space to store data.
num-pages-unmap-per-
minute
uint32 The number of 4 MB pages that host systems have unmapped per minute,
through use of the SCSI UNMAP command, to free storage space as a result
of deleting files or formatting volumes on the host.
num-pages-unmap-per-hour uint32 The number of 4 MB pages that host systems have unmapped per hour, through
use of the SCSI UNMAP command, to free storage space as a result of deleting
files or formatting volumes on the host.
num-blocked-ssd-promotions-
per-minute
uint32 The rate, in pages per minute, at which pages cannot be moved to SSD. A
consistent non-zero rate may indicate the SSD tier is too small for the current
workload.
num-blocked-ssd-promotions-
per-hour
uint32 The rate, in pages per hour, at which pages cannot be moved to SSD. A
consistent non-zero rate may indicate the SSD tier is too small for the current
workload.
num-page-allocations uint64 The number of pages allocated to volumes in the pool because they need more
space to store data.
num-page-deallocations uint64 The number of pages deallocated from volumes in the pool because they no
longer need the space to store data.
num-page-unmaps uint64 The number of 4 MB pages that host systems have unmapped since statistics
were last reset.
num-page-promotions-to-ssd-
blocked
uint64 The number of pages that could not be moved to SSD since statistics were last
reset.
num-hot-page-moves uint64 The number of “hot” pages promoted from lower tiers to higher tiers since
statistics were last reset.
num-cold-page-moves uint64 The number of “cold” pages promoted from lower tiers to higher tiers since
statistics were last reset.
