The number of data transfer operations
per second between cache memories
and data drives (for example, volumes)
LDEV_BackTransxx.csvLDEVEachOfCU_dat/LDEV_BackTrans.ZIP
The number of data transfer operations
per second from cache memories and
data drives (for example, volumes)

The number of data transfer operations
per second from data drives (for

The number of data transfer operations
per second from data drives (for

The average response time
(microseconds) at volumes
LDEV_Responsexx.csvLDEVEachOfCU_dat/LDEV_Response.ZIP
Note: The letters "xx" in CSV filenames indicate a CU image number. For example, if the filename is LDEV_IOPS
_10.csv, the file contains the I/O rate (per second) of the volumes controlled by the CU whose image number is 10.
Port statistics
The following table shows the file names and types of information in the Monitor Performance
window that can be exported to files using the Export Tool. These files contain statistics about ports.
