Overview
The XP12000 disk array is part of the HP StorageWorks XP Disk Array
family of products. These disk arrays provide reliable and secure data
storage and protection, featuring redundant circuitry and RAID storage
options for data security. These disk arrays also support multiple operating
systems, platforms, and RAID groups. Advantages include:
• Continuous data availability, page 12
• Nondisruptive service and upgrades, page 13
• Connectivity, page 14
• Scalability, page 15
• Data integrity and high availability, page 16

12 HP StorageWorks XP12000 Disk Array Owner’s Guide
Continuous data availability
The HP StorageWorks Disk Array XP family includes the first RAID disk
arrays to provide truly continuous data availability. XP disk arrays are
designed for nonstop operation and continuous access to all user data.
The following XP12000 features ensure continuous data availability:
• No single point of component failure, which enables uninterrupted
access to data
• Component and function redundancy, providing full fault tolerance for
disk array microprocessors, control storage, cache, control and data
buses, power supplies, and cooling fans
• Can sustain multiple component failures and still continue to provide
full access to stored data
Note Although access to data is not compromised, the failure of a key component
can cause a temporary reduction in disk array performance.

Overview 13
Nondisruptive service and upgrades
Without disrupting normal disk array operations (if alternate pathing is
used), an HP support representative can:
• Remove, service, repair, or replace hardware subassemblies
• Use the built-in service processor (SVP) to upgrade microcode
Alternate paths can be established using host failover software, alternate
Fibre Channel paths, or both.
Caution The disk array has no user-serviceable components. The SVP does not
include a keyboard or monitor and is not a customer-accessible component.
Only an HP support representative should open the cabinets.
HP StorageWorks Continuous Track XP monitoring software detects
internal hardware component problems and automatically reports them to
the HP Storage Technology Center (STC) before they are noticed by
operators and users. An HP support representative can then verify the
problem and perform the appropriate maintenance activity, with no
interruption to applications or hosts. For more information on Continuous
Track XP, see “HP StorageWorks Continuous Track XP” (page 31).

14 HP StorageWorks XP12000 Disk Array Owner’s Guide
Connectivity
The disk array uses these types of connections to connect to host systems:
• Fibre Channel
•ESCON
•FICON
Fibre Channel
The disk array supports:
• A maximum of seven1pairs of channel adapters that can support up to
224 Fibre Channel ports
• Up to 16,384 LDEVs that can be configured as up to 229,376 LUNs2
through the Fibre Channel, which provides data transfer rates up to 2
Gb/s depending on the Fibre Channel interface option
• Fibre Channel arbitrated loop (FC-AL) and Fabric Fibre Channel
topologies
ESCON
The disk array supports a maximum of four pairs of channel adapters that
can support 64 ESCON ports for connection to mainframe hosts and up to
16,384 LDEVs.
FICON
The disk array supports a maximum of four pairs of channel adapters that
can support up to 64 FICON ports and up to 16,384 LDEVs.
1. When more than four FC pairs are installed, each additional pair reduces the maximum number of ACP pairs by one. For
example, an array with six FC pairs can have a maximum of two ACP pairs installed.
2. The maximum number of LUNs is 1024 per installed FC port.

Overview 15
Scalability
The disk array is scalable to accommodate your current and future storage
capacity needs.
The minimum XP12000 configuration includes one DKC containing 9 to
128 disk drives. You can expand the disk array to include one to four
DKUs, each containing up to 256 disk drives. The maximum array
configuration can contain 1152 disk drives providing up to 165 TB of
storage capacity in a single array.
Your HP support representative can add DKUs and disk drives online with
no interruptions to applications or hosts.

16 HP StorageWorks XP12000 Disk Array Owner’s Guide
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
• 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 software features and products help to ensure that the disk
array meets your requirements for high availability:
• XP12000 support
– Capability to “phone home” to the multidisciplinary HP Storage
Technology Center (STC); see “HP StorageWorks Continuous
Track XP” (page 31)
– Advanced remote diagnostics
– Full solution (host-SAN-storage) support
• Full software and solution integration enabled by HP software
products; see Chapter 4 for details
