12 HP StorageWorks Disk Arrays XP128/XP1024: Owner’s Guide

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 stor age opt ions f or dat a secur ity. 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

Overview 13

Continuous data availability

The HP StorageWorks Disk Array XP family ar e the f irst RAID di sk ar rays to provide truly cont inuous data av ailab ility. They are designed for non stop 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 h as component and func tion red undancy, providing full fau lt tolerance for disk array microprocessors, control storage, control and data buses, power supplies , and cooling fans . The disk array can su stain multipl e 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.

14 HP StorageWorks Disk Arrays XP128/XP1024: Owner’s Guide

Nondisruptive service and upgrades

Monitoring software detects internal hardware component problems and notifies the HP Storage Technology Cent er 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.

General safety guidelines

Read the following safety guidelines carefully and follow them when you work with the HP StorageWorks Disk Array XP128 disk array.

• Remember that the maintenance of your machine must be done only by trained and qualified HP field engineers. Only an HP service representative can power off the disk array in a non-emergency situation.

• Please read and follow the safety guidelines and procedures in this manual and you other disk array manuals.

• In this manual and on the machine, hazard warnings are provided to aid you in preventing or reducing the risk of death, personal injury, or product damage. Understand and follow these hazard warnings fully.

• The hazard warnin gs tha t app ear on t he war nin g labe ls on the machine or in the manual have one o f the fol lowing aler t hea din gs cons isti ng of an alert symbol and a signal word, “Warning,” or “Caution”:

Warning

This indicates a potentially hazardous situation which, if not avoided, can result in death or serious injury.

Caution This indicates a hazard ous situation whic h, if not avoide d, will or can r esul t

in serious damage to the product or loss of data.

• The signal word “NOTICE” is used to present warnings that are not directly related to personal injury hazards.

• When warning labels become dirty or start peeling off, replace them.

• If any physical accident such as abnormal noise, smell, or smoke occurs on the dis k arra y while it is r unn ing, immedi atel y power of f the disk array by pulling the UNIT EMERGENCY POWER OFF switch on the disk array.

26 HP StorageWorks Disk Arrays XP128/XP1024: Owner’s Guide

• Do not power off the system unless it is an emergency power-off situation.

• Keep the front and rear doors closed at all times.

• Keep the tops and sides of the cabinets clear to allow air to flow properly.

• Do not perform any procedures not descr ib ed in this document. If you have any questions or concerns, please contact your HP service representative.

Warning

Do not touch areas marked HAZARDOUS, even with the po wer of f. The se areas contain high-voltage power.

Keep in mind that the hazard warnings in this manual or on the machine cannot cover every possib le case, as it is impossi ble to pred ict and eva luate all circumstances before hand.

Follow the procedures in this guide carefully and always be alert for any unusual equipment indications or behavior. If you have any questions, contact your HP service representative.

XP128 Hardware 27

Physical components

The HP StorageWorks Disk Array XP128 is a high-performance disk array system. It is used to store large quantities of data in an efficient and secure manner.

Figure 1. HP StorageWorks Disk Array XP128

Your disk array has the following major hardware components:

• Disk array cabinet The single disk array frame cabinet contains the control panel,

connection hardware, the service processor, control boards and hard disk drives.

• One service processor (SVP) The service processor (SVP) is a built-in PC inside the disk array

cabinet. The SVP gives your HP service representative a method of accessing the software system on the disk array.

Your HP service representative uses the SVP to configure, maintain, and upgrade your disk array software and hardware. The service

28 HP StorageWorks Disk Arrays XP128/XP1024: Owner’s Guide

processor also collects performance data about the disk array for diagnostic testing and analysis.

To ensure data security, the SVP does not have access to any user dat a stored on the disk array.

•(Optional) second service processor This is available for user s with ext reme high a vailabi lity re quirements .

This is not a required feature.

• Control panel The control panel is your view of the disk ar ray. Once the disk array is

powered on and running normally, there are no user operations required at the control panel, except in the case of a power failure recovery. The control panel is discussed in further detail on page 31.

• Hard disk drives The disk array uses 3.5-inch disk drives, and different disk capacities

are available. Ask your HP service representative about currently available disk drives or visit the XP128 web site at

http://www.hp.com. Any of the disk drives in t he disk array fra mes can

be replaced without disrupting user activity. The disk array automatically detects and correct s disk errors.

•(Optional) management station PC The management station PC is attached to your disk array by a local

area network (LAN) connecti on. The manageme nt stat ion PC runs HP Command View XP, which, combined with other optional applications, allows you to monitor and manage disk array operations.

The following figure illustrates how the management station PC and host connect to the XP128.

XP128 Hardware 29

Management Station PC

XP128 Disk Array

Host

Figure 2. The XP128 connections

1. The management station connects to the XP128 by means of a public LAN connection. The XP128 has an Ethernet connection to connect for this purpose.

2. The host server uses a Fibre Channel, FICON, iSCSI, or ESCON connection.

The hardware requirements for your management station PC, such as the required processor speed, storage capacity, and memory, will vary depending on the optional software that you use and the number of disk array frames you have connected to the system.

T o ens ure dat a secu ri ty, the HP Command V i ew XP soft ware doe s not ha ve access to any user data stored on the disk array.

There is no single point of failure in the disk array. It is designed with redundant logic assemblies, disk drives and power supplies, all of which can be removed or replaced without interrupting access to your data.

Caution Only your HP service representative can remove or replace hardware.
