Overview of XP Auto LUN
XP Auto LUN enables you to optimize your data storage and migrate volumes on the storage
system. XP Auto LUN tuning operations can be used to balance resource utilization and resolve
bottlenecks of system activity.
Volume Migration to Balance Workloads
If I/O accesses from hosts converge on particular hard disk drives, the hosts might suffer from
slower response times. To overcome this situation, XP Auto LUN lets you migrate high-usage volumes
to a low-usage hard disk drive or a fast hard disk drive. Volume migration can balance workloads
among hard disk drives and thus remove bottlenecks from the system. Volume migration can also
balance workloads among disk processors, which control disk I/Os.
XP Auto LUN operations are either manual migrations or automated (auto) migrations.
