Live PoolThe name of the pool. Pages
Allocated per MinThe rate, in pages per minute,
at which pages are allocated to volumes in the pool because they need
more space to store data. Pages Deallocated per MinThe 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 Unmapped per MinuteThe 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. Time Since ResetThe amount of time,
in seconds, since these statistics were last reset, either by a user
or by a controller restart. ReadsThe number of read operations since these statistics were last reset
or since the controller was restarted. WritesThe number of write operations since these statistics
were last reset or since the controller was restarted. Data ReadThe amount of data read since these
statistics were last reset or since the controller was restarted. Data WrittenThe amount of data written
since these statistics were last reset or since the controller was
restarted. BpsThe data transfer
rate, in bytes per second, calculated over the interval since these
statistics were last requested or reset. This value will be zero if
it has not been requested or reset since a controller restart. IOPSThe number of input/output operations
per second, calculated over the interval since these statistics were
last requested or reset. This value will be zero if it has not been
requested or reset since a controller restart. I/O Resp
TimeThe average response time, in microseconds,
for read and write operations since the last sampling time. Read Resp TimeShown by the <codeph>all</codeph>
parameter. The average response time, in microseconds, for read operations
since the last sampling time. Write Resp TimeShown by the <codeph>all</codeph> parameter. The
average response time, in microseconds, for write operations since
the last sampling time. Historical For a pool: PoolThe name of the pool. Total
I/OsThe total number of read and write operations
since the last sampling time. ReadsShown by the <codeph>all</codeph> parameter. The number of
read operations since the last sampling time. WritesShown by the <codeph>all</codeph> parameter.
The number of write operations since the last sampling time. Data TransferredThe total amount of data
read and written since the last sampling time. Data ReadShown by the <codeph>all</codeph> parameter.
The amount of data read since the last sampling time. Data
WrittenShown by the <codeph>all</codeph>
parameter. The amount of data written since the last sampling time. Total IOPSThe total number of read
and write operations per second since the last sampling time. Read IOPSShown by the <codeph>all</codeph>
parameter. The number of read operations per second since the last
sampling time. Write IOPSShown
by the <codeph>all</codeph> parameter. The number of write operations
per second since the last sampling time. Total B/sThe total data transfer rate, in bytes per second,
since the last sampling time. Read B/sShown by the <codeph>all</codeph> parameter. The data transfer
rate, in bytes per second, for read operations since the last sampling
time. Write B/sShown by the <codeph>all</codeph>
parameter. The data transfer rate, in bytes per second, for write
operations since the last sampling time. Allocated PagesThe number of 4 MB pages allocated to volumes in
the pool. Sample TimeDate and time,
in the format year-month-day hour:minutes:seconds, when the data sample was taken. For each tier in the pool: PoolThe name of the pool. TierThe name of the tier. Total I/Os, Reads, Writes,
Data Transferred, Data Read, Data Written, Total IOPS, Read IOPS,
Write IOPS, Total B/s, Read B/s, Write B/sAs described for a pool, above. Allocated PagesThe number of 4 MB pages allocated to volumes in
the tier. Page Moves InThe number
of pages moved into this tier from a different tier. Page
Moves OutThe number of pages moved out of
this tier to other tiers. Page RebalancesThe number of pages moved between disks in this tier
to automatically load balance. Initial AllocationsThe number of 4 MB pages that are allocated as a
result of host writes. This number does not include pages allocated
as a result of background tiering page movement. (Tiering moves pages
from one tier to another, so one tier will see a page deallocated,
while another tier will show pages allocated. These background moves
are not considered initial allocations.) UnmapsThe number of 4 MB pages that are automatically reclaimed
and deallocated because they are empty (they contain only zeroes for
data). RC CopiesThe number of
4 MB pages copied from spinning disks to SSD read cache (read flash
cache). Zero-Pages ReclaimedThe
number of empty (zero-filled) pages that were reclaimed during this
sample period. Sample TimeDate
and time, in the format year-month-day
hour:minutes:seconds, when the data sample was
taken. |
