Revision history
July 2005 First edition

Overview 11
1
Overview
The XP10000 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 17

12 HP StorageWorks XP10000 Disk Array Owner’s Guide
Continuous data availability
The HP StorageWorks Disk Array XP family is among 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 XP10000 features ensure continuous data availability:
• No single point of component failure, which enables uninterrupted
access to data
• Component and function redundancy, providing fault tolerance for
disk array microprocessors, control storage, cache, control and data
buses, power supplies, and cooling fans
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, nonstop SCSI, or combination solutions.
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 XP10000 Disk Array Owner’s Guide
Connectivity
The disk array supports a standard set of channel adapters (and disk
adapters) on the Mix board, and one pair of optional channel adapters. The
adapters provide or are planned to provide the following types of
connections to host systems:
•Fibre Channel: Open System, FC-AL or Fabric, 1 or 2 Gb/s, single or
multimode, LC-Duplex
•ESCON: mainframe, serial
•FICON: mainframe, LC-Duplex, 1 or 2 Gb/s, single or multimode
•NAS: Open System, Gigabit Ethernet
Note: Some connection types may not be available with the initial XP10000
product release but are expected to become available soon afterwards.

Overview 15
Scalability
The disk array is scalable to accommodate your current and future storage
capacity needs.
Figure 1 shows the disk array equipment racks.
In the basic configuration, the disk array consists of one primary 19-inch
rack containing the following:
• One disk controller with control panel and SVP blade PC
• One 60-disk chassis, consisting of two 30-drive HDU boxes
• Mix board with disk adapters and host ports
• Power supplies, power distribution units (PDUs), backup batteries,
power cords, and cabling
You can expand the primary rack as follows:
• Add one 60-disk chassis containing two 30-drive HDU boxes to the
top space of the primary rack. This provides a total of up to 120 drives
After expanding the primary rack, you can add a second 19-inch rack with
additional disk units as follows:
• Add one 60-disk chassis to the second rack for a total of up to 180
drives
• Add a second 60-disk chassis to the second rack for a total of up to 240
drives
Disk array basic storage includes disk chassis R0 in the primary rack. Add
more disk chassis in the order shown in Figure 1: R1, R2, R3.
Your HP support representative can add disk chassis and disk drives online
with no interruptions to applications or hosts.
Note: The initial release of the XP10000 disk array may not include a second
rack. This option is expected to become available soon after release.

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
• Mirrored write cache
• Dual channel adapters (CHAs)
• 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:
• XP10000 support
– Capability to “phone home” to the multidisciplinary HP Storage
Technology Center (STC). See “HP StorageWorks Continuous
Track XP” (page 31) for details
– Advanced remote diagnostics
– Full solution (host-SAN-storage) support
• Full software and solution integration enabled by HP software
products. See Chapter 4 beginning on page 47 for details
