1 Overview of the HP XP24000/XP20000

Disk Array

This disk array is part of the HP StorageWorks XP series of high-performance RAID-capable disk array

systems used to store large quantities of data in an efficient and secure manner. XP disk arrays support

multiple operating systems, platforms, and RAID groups. Advantages include:

• Continuous data availability

• Nondisruptive service and upgrades

• Connectivity

• Scalability

• Data integrity and high availability

Outstanding performance, capacity, and reliability

The HP StorageWorks XP24000/XP20000 Disk Arrays provide high performance, high capacity,

and solid reliability in a large storage system that can start as small as a single frame and expand

as your storage needs grow. Coupled with HP's comprehensive customer support, the

XP24000/XP20000 disk arrays offer a safe data storage investment that will serve your needs for

years to come.

Continuous data availability

XP disk arrays are designed for nonstop operation and continuous access to all user data.

The highest data availability is achieved by the following features:

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

• Mirrored write cache

• Dual channel adapters (CHAs) and disk adapters (DKAs)

• 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

• Remote health and alert monitoring by HP customer support using HP StorageWorks XP Continuous

Track software and HP Insight Remote Support Advanced

The following optional features ensure the disk array meets your requirements for high availability:

• Advanced remote diagnostics

• Full solution (host-SAN-storage) support

• Full software and solution integration enabled by HP software products

XP24000/XP20000 Disk Array Owner Guide 7

NOTE:

Although access to data is not compromised, the failure of a key component can cause a temporary

reduction in disk array performance.

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

• Perform remote error monitoring, diagnosis, and maintenance

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.

The HP StorageWorks XP C-Track monitoring software and HP Insight Remote Support Advanced

product detects problems and automatically reports them to the HP Storage Technology Center (STC).

An HP support representative can then verify the problem and perform the appropriate remote

maintenance activity with no interruption to applications or hosts. For more information about C-Track,

see “HP StorageWorks XP Continuous Track” on page 43. For more information about HP Insight

Remote Support Advanced, see “HP Insight Remote Support Advanced” on page 43

Connectivity

The system can be configured to provide the following types of host connections:

• Fibre Channel: 8 or 16 ports per adapter pair, up to 4 Gbps, SW or LW

• ESCON: 8 ports per adapter pair, up to 17 MB

• FICON: 8 ports per adapter pair, up to 4 Gbps, SW or LW

Figure 1 shows a simple storage area network (SAN) containing an XP24000/XP20000 disk arrays.

Figure 1 Disk array simplified SAN connection

Scalability

The disk arrays are scalable to accommodate your current and future storage capacity needs.

XP24000 basic configuration

The XP24000 configuration consists of a disk control frame (primary rack) that can have 128HDDs

and zero to 4 disk array frames (DKU) that can each have 256 HDDs for a total of 1152 hard drives.

The disk array provides a flexible configuration that can include:

• Number of installed channel options: Channel Adapters (CHAs) 1 to 14 adapters (each DKA set

above 4 reduces the maximum number of CHAs by two)

• Fibre Channel: up to 224 ports

• ESCON: up to 112 ports

• FICON: up to 112 ports

• Capacity of cache memory: 4 GB to 512 GB

• Up to 1152 HDDs

Your HP support representative can add DKUs and disk drives online with no interruptions to

applications or hosts.

XP20000 basic configuration

The XP20000 configuration consists of a disk control frame (primary rack) that can have 120 HDDs,

and a disk array frame (secondary rack) that can have 120 HDDs. The disk array provides a flexible

configuration that can include:

• Number of installed channel options: 1 to 3 sets

• Capacity of cache memory: 4 GB to 128 GB

• Up to 240 HDDs/8 disk paths

In the basic configuration, the disk array consists of one primary 19–inch rack containing the following:

• One disk controller that consists of the channel adapters, disk adapters, cache memory adapters,

shared memory adapters, and CSW

• Battery boxes and power supplies that supply power to the components

XP24000/XP20000 Disk Array Owner Guide 9

• One 60-disk chassis

Adding storage

You can add more disk chassis in this order: R0, R1, R2, and R3. Each disk chassis contains 60 hard

disk drives.

Your HP support representative can add disk chassis and disk drives online with no interruptions to

applications or hosts. Additional details about each rack follow.

Primary rack expansion

In addition to the basic disk chassis R0, you can expand the disk array in the primary rack as follows:

• Add 60-disk chassis R1 to the top space of the primary rack. This provides a total of up to 120

drives.

Secondary rack expansion

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

Flexibility

The new optional HP StorageWorks XP Thin Provisioning software significantly improves system

flexibility while also decreasing storage costs. Using this solution, you begin operation with a global

pool of LDEVs that are not assigned to physical storage. The disk arrays add virtual capacity from

the pool of LDEVs on the fly as data is written, and only at that time is physical capacity assigned to

LDEVs and consumed.

Later, if you need additional storage capacity, you can add it without downtime. To create new LDEVS,

the system simply continues to use LDEVs from the pool, assigning them to the new physical storage

automatically as required.

For more information, see the HP StorageWorks XP24000/XP20000 Thin Provisioning User Guide.

Data encryption

HP StorageWorks DKA Encryption License Key provides physical disk encryption (AES-256) compatible

with open and mainframe systems. Encryption can be applied to some or all internal drives with no

throughput or latency impacts for data I/O and with little or no disruption to existing applications

and infrastructure. HP DKA Encryption License Key includes integrated key management functionality

that is both simple and safe to use. For more information, see the HP StorageWorks XP24000/XP20000

Disk Encryption User Guide or contact your HP account representative.

2 Hardware description of t he HP

XP24000/XP20000 Disk Array

The HP StorageWorks XP series of disk arrays are high-performance RAID-capable disk array systems

used to store large quantities of data in an efficient and secure manner.

There are no single points of failure in the disk arrays. They include redundant logic assemblies,

controllers, power supplies, and dual-ported RAID disk drives, all of which can be removed or replaced

without interrupting access to data. This chapter describes the physical components of the disk array.

CAUTION:

Only your HP support representative can remove or replace hardware.

XP24000 system architecture

As Figure 2 shows, the basic XP24000 disk array consists of a DKC cabinet containing two main

sections: a logic box and an HDD box.

The logic box includes channel adapters (CHA) that provide server and other interfaces, disk adapters

(DKA) for controlling disk drives, cache memory adapters (CMA), and shared memory adapters

(SMA).

The HDD box contains the disk drives and a Fibre switch that interfaces the drives to the DKAs.

Additional disk drives can be added by installing up to four optional DKU cabinets containing multiple

additional HDD boxes.

Components interact by way of the data paths shown in the figure.

Also included but not shown in Figure 2 are the AC-DC power supplies and backup batteries.

XP20000 system architecture

Figure 3 shows, the basic XP20000 disk array consists of three main sections: the power supply, a

DKC, and a DKU.

The power supply section consists of the AC-DC power supplies and battery boxes.

The DKC consists of the channel adapters (CHAs), disk adapters (DKAs), cache memory adapters

(CMAs), and shared memory adapters (SMAs).

The DKU consists of the disk drives and Fibre Channel switches (FSW, not shown).

Each component is connected with the cache paths, SM paths, and/or disk paths shown in the figure.
