3.5.7 Using the Statistics Window

The Statistics window includes separate displays for cache hits and for sustained read/write performance.

Cache hits average and history provides information about the current operating performance of the RAID controller and disk array.

CacheHits Average is a measure of data read or write cache accesses at the most recent moment of sampling. It indicates what percentage of data I/O is cache accessed.

Cache Hits History shows cache read and write hit data over the last few minutes and indicates data caching consistency and frequency.

Sustained Read/Write Performance is also displayed as both an average and historically. Read/write performance is another way to evaluate the current RAID controller and disk array I/O throughput.

Read/Write Average is a measure of the average data throughput, in MB/second, at the most recent data sample.

Read/Write History shows read/write performance over the last few minutes and indicates data throughput consistency.

The read/write data display scale can be modified using the Adjust button at the bottom-center of the Read/Write Statistics window. Scales from 10MB/second to 200MB/second are available.
