Overview
The Disk Array XP128 and Disk Array XP1024 are part of the HP
StorageWorks 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. The
advantages include:
• Continuous data availability
• Nondisruptive service and upgrades
• Connectivity
• Scalability
• Data integrity

12 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide
Continuous data availability
The HP StorageWorks Disk Array XP family are the first RAID disk arrays
to provide truly continuous data availability. They are designed for nonstop
operation and continuous access to all user data.
HP StorageWorks Disk Array XP128 and XP1024 disk arrays have no
single point of component failure, which enables uninterrupted access to
data.
The disk array has component and function redundancy, providing full fault
tolerance for disk array microprocessors, control storage, control and data
buses, power supplies, and cooling fans. The disk array can sustain multiple
component failures and still continue to provide full access to your stored
data.
While access to your data is never compromised, the failure of a key
component can cause a temporary reduction in disk array performance.

Overview 13
Nondisruptive service and upgrades
Monitoring software detects internal hardware component problems and
notifies the HP Storage Technology Center automatically. At the support
center, the problem is verified and the appropriate maintenance activity is
executed by an HP service representative. The are no user serviceable
components. Only an HP service representative should open the cabinets.
All hardware subassemblies can be removed, serviced, repaired, or
replaced non-disruptively during disk array operation. All microcode
upgrades can be performed during normal disk array operations (provided
array connectivity infrastructure requirements are satisfied), using your
disk array’s built-in service processor (SVP). Alternate paths can be set by
host failover software and/or alternate Fibre Channel paths.

Connectivity
The HP StorageWorks Disk Array XP128 and HP StorageWorks Disk
Array XP1024 are connected to host systems using one of these types of
connections:
• Fibre Channel
•ESCON
•FICON
• iSCSI
Fibre Channel connectivity
HP StorageWorks Disk Array XP128
The XP128 supports a maximum of three pairs of channel adapters that can
support up to 48 Fibre Channel ports. Your disk array can support up to
8,192 LDEVs which can be configured as up to 24,576 LUNs through the
Fibre Channel. The Fibre Channel provides data transfer rates up to
2GB/sec depending on which Fibre Channel interface option is installed.
The disk array can support Fibre Channel Arbitrated Loop (FC-AL) and
Fabric Fibre Channel topologies.
HP StorageWorks Disk Array XP1024
The XP1024 supports a maximum of four pairs of channel adapters that can
support up to 64 Fibre Channel ports. Your disk array can support up to
8,192 LDEVs which can be configured as up to 32,768 LUNs through the
Fibre Channel. The Fibre Channel provides data transfer rates up to
2GB/sec depending on which Fibre Channel interface option is installed.
The disk array can support Fibre Channel Arbitrated Loop (FC-AL) and
Fabric Fibre Channel topologies.

Overview 15
ESCON connectivity

support 24 ESCON ports for connection to mainframe hosts. The disk array
can support up to 8,192 LDEVs.
HP StorageWorks Disk Array XP1024
The XP1024 supports a maximum of six pairs of channel adapters that can
support 48 ESCON ports for connection to mainframe hosts. The disk array
can support up to 8,192 LDEVs.
Note: When more than four pairs of ESCON channel adapters are
configured, the number of disk drives that can be installed is reduced. Other
restrictions may apply, depending on what other types of channel adapters
are installed.
FICON connectivity
HP StorageWorks Disk Array XP128

LDEVs through iSCSI.
HP StorageWorks Disk Array XP1024
The XP1024 supports a maximum of four pairs of channel adapters that can
support up to 32 iSCSI ports. Your disk array can support up to 8,192
LDEVs through iSCSI.

Overview 17
Data integrity
HP disk arrays provide the highest levels of data integrity. This is
accomplished using RAID technologies, together with redundant hardware
throughout the disk array. The following hardware features allow the HP
StorageWorks Disk Array XP family to achieve its high availability and
data integrity:
•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
