Displaying Overall Statistics
This function allows the user to view two (2) types of aggregate statistics for all partition LUNs:
• General statistics (Similar statistics are also available for individual partition LUNs.
Refer to section "Viewing Partition Statistics" for further information.)
- I/O operations per second (IOPS)
- Bandwidth (in MBytes/second)
- Number of read operations
- Number of write operations
- Total sectors written
- Total current command queue depth across all LUNs
• Host read/write histogram - shows how many host reads and writes fall into
a particular size range (I/O ranges are based on powers of two).
- 1 Sector
- 2-3 Sectors
- 4-7 Sectors
- 8-15 Sectors
- 16-31 Sectors
- 32-63 Sectors
- 64-127 Sectors
- 128-255 Sectors
- 256-511 Sectors
- 512-1023 Sectors
- 1024-2047 Sectors
- 2048 (and up) Sectors
This information may be helpful in interpreting performance based on individual system
configurations and operating systems. The information displayed here can be useful in profiling
applications and their usage of the partition, and determining what type of RAID level is
applicable to the user's needs.
NOTE: The statistics are provided as general information. They are not intended for bench-
marking purposes.
