• 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—The average number of BUSY responses sent per second, during the

polling interval, for WRITE SAME operations due to a queue full condition.

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.
