WSAME Dest Other Req/s
—The average number of WRITE SAME requests arrived per
second, where the destination LUN is owned by other controller, calculated over the polling
interval.

WSAME Ave Queue Depth
—Average number of WRITE SAME requests that are pending,
calculated over the polling interval.
•
WSAME Busies/s

HP EVA Unmap Metrics
The HP EVA unmap metrics provides the summary of performance data for unmap commands.
Each controller’s activity is reported separately.
The counters are:
•
UNMAP Completed Req/s
—The average number of UNMAP requests completed per
second, calculated over the polling interval.
•
UNMAP Latency
—The average time, in milliseconds, taken to complete one UNMAP request,
averaged over all the UNMAP requests completed during the polling interval.
•
UNMAP Arrived Req/s
—The average number of UNMAP requests received per second,
calculated over the polling interval.
•
UNMAP Failed Req/s
—The average number of UNMAP requests failed per second,
calculated over the polling interval.
•
UNMAP Dest This Req/s
—The average number of UNMAP requests arrived per second,
where the destination LUN is owned by this controller, calculated over the polling interval.
•
UNMAP Dest Other Req/s
—The average number of UNMAP requests arrived per second,
where the destination LUN is owned by other controller, calculated over the polling interval.
•
UNMAP Completed MB/s
—The data rate at which the storage space is requested to be
reclaimed by the host issued and completed UNMAP requests, calculated over the polling
interval.
•
UNMAP Reclaimed MB/s
—The data rate at which the storage space is actually reclaimed
as a result of completed UNMAP requests, calculated over the polling interval.
•
UNMAP Ave Queue Depth
—Average number of UNMAP requests that are pending,
calculated over the polling interval.
•
UNMAP Busies/s
—The average number of BUSY responses sent per second, during the
polling interval, for UNMAP operations due to a queue full condition.
