10 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 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

Overview 11

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.

12 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 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.

Overview 13

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

•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

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 warnings that appear on the warning labels on the machine or in the manual have one of the following alert headings consisting 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 hazardous situation which, if not avoided, will or can result

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 disk array while it is running, immediately power off the disk array by pulling the UNIT EMERGENCY POWER OFF switch on the disk array.

24 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 described 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 power off. These areas contain high-voltage power.

Keep in mind that the hazard warnings in this manual or on the machine cannot cover every possible case, as it is impossible to predict and evaluate 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 25

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

26 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 data stored on the disk array.

•(Optional) second service processor

This is available for users with extreme high availability requirements. This is not a required feature.

• Control panel The control panel is your view of the disk array. 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 29.

• 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 the disk array frames can

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

•(Optional) Device Manager server The Device Manager server is attached to your disk array by a local

area network (LAN) connection. The Device Manager server runs HP Command View XP and/or Command View XP Advanced Edition which, combined with other optional applications, allows you to monitor and manage disk array operations.

The following figure illustrates how the Device Manager server and host connect to the XP128.

Device Manager server

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 for this purpose.

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

The hardware requirements for your Device Manager server, 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.

To ensure data security, neither edition of HP Command View software (CVXP or CVXP AE) has 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.

If your disk array is set up to report messages to the remote center, your HP service representative is notified automatically. If the disk array is not set up to report messages to the remote center, you should place a service call to HP to have the message evaluated to determine if any action is required.
