System requirements

and the licensed XP External Storage feature enabled on XP Command View Advanced Edition

Software or Remote Web Console. System requirements for XP External Storage are:

• Local array (first array)

Install and enable all hardware and microcode required for XP External Storage operations

in the local array.

CAUTION: Before installing and enabling the hardware and microcode, see “Managing

cache with external storage” (page 46) for instructions.

• External array (second array)

You also need a second storage device, called an external array in this user guide. For more

information, see “Storage arrays that can be connected as external arrays” (page 10).
