The number of data transfer operations
per second between cache memories
LDEV_BackTransxx.csvLDEVEachOfCU_dat/LDEV_BackTrans.ZIP
and hard disk drives (for example,
volumes)
The number of data transfer operations
per second from cache memories and
hard disk drives (for example, volumes)
LDEV_C2D_Transxx.csvLDEVEachOfCU_dat/LDEV_C2D_Trans.ZIP
The number of data transfer operations
per second from hard disk drives (for
LDEV_D2CS_Transxx.csvLDEVEachOfCU_dat/LDEV_D2CS_Trans.ZIP
example, volumes) to cache memories
in sequential access mode
The number of data transfer operations
per second from hard disk drives (for
LDEV_D2CR_Transxx.csvLDEVEachOfCU_dat/LDEV_D2CR_Trans.ZIP
example, volumes) to cache memories
in random access mode
The average response time
(microseconds) at volumes
LDEV_Responsexx.csvLDEVEachOfCU_dat/LDEV_Response.ZIP
Note: 1 microsecond is one-million of 1 second. 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.
