Read/Write Detail report
The Read/Write Detail report displays in a chart format, the total I/Os separated into different I/O types.
This includes sequential reads and writes and random reads and writes, displayed as the number of I/O
operations per second. The graph provides more detail than the previous graphs about the types of I/Os
occurring on an XP disk array. Figure 17: Read/Write Detail on page 309 displays a sample Read/Write
Detail by hour of day report for a P9500 Disk Array.
