30 Auto LUN XP for the XP12000/XP10000
NOTE: High-speed (2 port) mode is available only if the XP disk array has firmware version 21.06.22 or
later installed.
In short range, if I/O workloads between hosts and the disk array become heavy, the disk array gives
higher priority to I/O processing than monitoring processing; therefore, some monitoring data might be
missing. If monitoring data is missing frequently, use the Gathering Interval option in the Monitoring
Options pane to increase the collection interval.
NOTE: Short-range monitoring data and long-range monitoring data may have some margin of error.
