This includes sequential reads and writes and random reads and writes, displayed as the number of
IO operations per second. This graph provides more detail than the previous graphs about the types
of IO/s occurring on the XP array. “Read/Write Detail” on page 330 shows a sample Read/Write

128 busiest front end and back end LDEVs, and 8 - 32 busiest front end and back end RAID groups.
