Number of seconds since the controller was restarted. Percentage of write cache in use, from 0-100. Data transfer rate 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. Unformatted bytes-per-second value. 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. For the controller whose host ports had I/O activity, the number of read operations since these statistics were last reset or since the controller was restarted. For the controller that owns the volume, the number of times the block to be read is found in cache. For the controller that owns the volume, the number of times the block to be read is not found in cache. For the controller whose host ports had I/O activity, the number of write operations since these statistics were last reset or since the controller was restarted. For the controller that owns the volume, the number of times the block written to is found in cache. For the controller that owns the volume, the number of times the block written to is not found in cache.
