Scalability

The disk array is scalable to accommodate your current and future storage capacity needs.

The minimum XP12000 configuration includes one disk controller (DKC) containing 9 to 128 disk

drives. You can expand the disk array to include one to four disk units (DKUs), each containing up

to 256 disk drives. The maximum array configuration can contain 1152 disk drives providing up to

332 TB of raw storage capacity in a single array.

An HP support representative is required to add DKUs and disk drives. DKUs and disk drives can be

added online without interruption to applications or hosts.

To provide the highest levels of data integrity and availability, the HP StorageWorks XP Disk Array

family uses RAID technologies and redundant hardware throughout the disk arrays, including:

• RAID1, RAID5, RAID6 (mixing RAID levels is allowed)

• Mirrored write cache

• Dual channel adapters (CHAs) and array control processors (ACPs)

• Dual and concurrently active data and control paths through the array

• Split power domains on internal data paths

• Hot-pluggable boards

• Hot-pluggable fans, power supplies, and controllers

• Online upgradable firmware

The following features and products help ensure the disk array meets your requirements for high

availability:
