Figure 39 Total I/O Rate Detail
The sequential frontend I/Os are when data is read from or written to consecutive addresses. The
random frontend I/Os are when applications address non-consecutive blocks of data. CFWs are
a special class of I/Os generated by HP's P9000 Continuous Access Remote Mirroring software.
NOTE: If there are no data points available for the dates selected, blank chart is displayed. If
all the data values are zero for the dates selected, a chart with a horizontal line along X axis is
displayed in the center of the chart.
Read/Write Ratio report
The Read/Write Ratio report displays in a chart format, the ratio of read activity to write activity,
over the entire period. It is for both sequential and random read, or write activity. “Read/Write
Ratio” (page 365) displays a sample Read/Write Ratio report for a P9500 Disk Array.
