Connectivity The system can be configured to provide the following types of host connections: • Fibre Channel: Open Systems; FC-AL or Fabric; 1, 2, or 4 Gbps, single or multimode; LC-Duplex • ESCON: mainframe, serial • FICON: mainframe, LC-Duplex, single or multimode, 1, 2, or 4 Gbps • iSCSI: 8 ports per adapter, 1 Gbps • NAS: 8 ports per adapter, 1 Gbps 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. Data integrity and high availability 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: • Capability to report errrors by modem or Internet to the HP Storage Technology Center (STC) using the HP StorageWorks XP Continuous Track (see "HP StorageWorks XP Continuous Track" on page 16) • Advanced remote diagnostics • Full solution (host-SAN-storage) support • Full software and solution integration enabled by HP software products 12 Overview of the HP XP12000 Disk Array

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.
Data integrity and high availability
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:
•
Capability to report errrors by modem or Internet to the HP Storage Technology Center (STC) using
the HP StorageWorks XP Continuous Track (see
“
HP StorageWorks XP Continuous Track
” on page 16)
•
Advanced remote diagnostics
•
Full solution (host-SAN-storage) support
•
Full software and solution integration enabled by HP software products
