4.4 Displaying Overall Statistics

You can display two types of aggregate statistics for all arrays:

•Rate statistics (for all arrays and each individual array):

–I/O operations per second (IOPS)

–Bandwidth (in millions of bytes per second)

•Cumulative statistics for all arrays

–Number of read operations

–Number of write operations

–Total sectors (512 bytes) read

–Total sectors written

–Total current command queue depth across all LUNs

–Host read/write histogram that shows how many host reads and writes fell into a particular size range. The I/O ranges are based on powers of two.

Similar statistics are also available for individual arrays and partitions. For more information, see 3.3.1, ”Viewing Array and Partition Statistics”, on page 21.

Tip: This information may be helpful in interpreting performance based on individual system configuration such as HBA, driver configuration, SAN configuration, and host operating system configuration. The statistical information can be useful to profile applications and their usage of an array, which could be used to determine if additional arrays would increase performance and what type of RAID level is applicable to your needs. You may want to analyze the performance of the same application using different RAID levels to determine which level gives you the best performance. See Appendix A, ”Array Basics”, on page 89 for more details on RAID levels.

Note The statistics are provided as general information for your use, however, they are not intended for benchmarking purposes.

To view the overall rate statistics:

•From SAM, select Monitor Galaxy 65 Subsystem > Statistics To view the cumulative statistics:

•From SAM, select Monitor Galaxy 65 Subsystem > Statistics > Cumulative Stats.
