XP Auto LUN lets you balance workload among hard disk drives, volumes (LUs) and processors to
remove bottlenecks from your system. If Performance Monitor indicates that a great number of I/Os
are made to some hard disk drives, you can use XP Auto LUN to distribute workloads to other disk
drives. For details, see the HP StorageWorks XP24000/XP20000 Auto LUN Software User's Guide.
Restrictions : The Auto Migration function is not supported in this version.
XP Performance Control lets you tune the system to provide high-priority hosts with relatively higher
throughput. XP Performance Control can prevent production servers from suffering lowered performance.
For details, see “Overview of Performance Control” on page 11.
