Chapter 1 Introduction

About the RAID Storage Chassis

This RAID Storage provides a compact, high-capacity, high-availability source of disk storage for the Profile Professional Disk Recorder. A single RAID Storage chassis offers a large capacity of high-availability disk storage in as many as 20 disk modules that can individually be replaced while the system is powered up.

Two models are available, the PRS250 and the PRS250M. The PRS250M offers two storage processors, which increase the bandwidth of the RAID chassis.

Approximate storage times

Video Compression Type 10 Disk Drives 15 Disk Drive 20 Disk Drives

M-JPEG 6 hours 9 hours 12 hours MPEG 12 hours 18 hours 24 hours

At 24 Mb/sec for MJPEG, 8 Mb/sec for MPEG, 4 audio tracks per video

The following table lists the maximum number of RAIDs that can be connected to a Profile Professional Disk Recorder.

RAID Storage Components

The RAID Storage chassis contains the components listed below.

• One (PRS250) or two (PRS250M) storage-control processors (SP).

• 10, 15, or 20 disk drive modules.

• One fan module.

• Three voltage semi-regulated converters (VSCs) power supplies The SPs, disk modules, fan module, and VSCs in the RAID Storage chassis are

customer-replaceable units (CRUs), which you can install or replace yourself. The following illustration shows the location of the RAID’s CRUs, which also

include the SCSI bus cable, SCSI terminator plug, power cord, and the optional asynchronous cables. In addition to the CRUs, the RAID Storage chassis contains field-replaceable units (FRUs). Only qualified service personnel should replace an FRU.

board

TheSP consists ofa printed circuitboard with two or four memory modules (DIMMs) and a bezel with status lights, and latches to secure the SP in place. The memory modules provide 32 Mbytes of SP memory. The SP uses 4Mbytes of this memory for system buffers. The remaining memory is available for system use.

Two status lights on the SP indicate the following:

Ready light (green) — Lights while the SP is powered on and operating normally. Service light (amber) — Lights when the SP is not working properly.

The SPs are visible when you swing the fan module down from the back of the RAID Storage chassis.

The SPprocesses data written to or read from the disk drive modules, and controls the disk modules in the storage chassis through a synchronous SCSI bus. It has five internal SCSI buses, each supporting four disk drive modules for a total of 20 disk drive modules. The Disk Array Storage System Manager (dassmgr) uses an RS-232 connection to the RAID Storage chassis to communicate with an SP. Using the dassmgr, you can set up RAID Storage memory, bind disk modules into logical units (LUNs), update the RAID Storage Licensed Internal Code, and check RAID Storage status.

A second SP increases the RAID chassis bandwidth for improved performance, provided the two SPs are connected to separate SCSI busses. Do not connect both SPs to the same SCSI bus.

IMPORTANT You should never attempt to replace any of the SP’s components, except the memory modules.

Three status lights on the module indicate the following: Ready light (green) — Lights while the disk drive module is powered up and ready

for use. Busy light (green) — Lights while the drive is in use; for example, during formatting

or user I/O operations. Fault light (amber) — Lights when the module is shut down by the SP because the

module failed. Also lights after you replace the drive, while the replacement drive spins up to speed.

You can remove or install any one module at a time within a group of five drives either while the storage chassis is running or in the idle mode (not running). You should never open a disk drive module or attempt to replace any of its internal components.

RAID Instructions 1-5

Chapter 1 Introduction

Voltage Semi-regulated Converters (VSCs)

The VSCs are power supplies that convert the installation site’s ac line voltage to the 48, 24, and 18Vdc required to power the modules in the RAID Storage chassis. The chassis contains three VSCs for high-availability operation.

Replace light

(amber)

Ready light

(green)

Two status lights on each VSC indicate the following:

Ready light (green) — Lights while VSC is operating normally. Replace light (amber) — Lights when the SP determines that the VSC has failed.

The VSCs are visible when you swing the fan module down on the back of the RAID Storage chassis.

You can remove or install a VSC while the storage chassis is running. If a VSC fails, replace it as quickly as possible. With three VSCs, if one of them fails,

the RAID Storage continues to operate but you still should replace the failed VSC as soon as possible to restore high-availability operation. Failure to replace the VSC could cause the RAID Storagechassis to shut downif either the fan module or another VSC fails. You should never open a VSC or attempt to replace any of its internal components.

1-6 RAID Instructions

Fan Module

The RAID Storage chassis uses a single fan module, also called a fan pack, that attaches to the back of the chassis. The fan module contains six high-capacity, multiple speed fans, and a control/monitor board.

Fan Module

Replacelight

(amber)

Lock

One status light on the fan module indicates the following: Replace light (amber) — Lights when a fan in the module is not working. For high-availability operation, if a fan stops working, the remaining five fans speed

up to maintain air flow. The Replace light turns on to indicate that you must replace the fan module as soon as possible.

The fan module is mounted on hinges so you can swing it down away from the chassis. A mechanical lock and magnetic catches hold the fan module closed.

NOTE:If the fan moduleremains open formore than approximately 2minutes, the storage chassis automatically shuts down to prevent overheating.

You can remove a fan module while the storage chassis is running. You should never open the module or attempt to replace any of its internal components. If one of the fans in the module fails, replace the fan module as quickly as possible to maintain high-availability operation. Failure to replace the module could cause the RAID Storage to shut down if either a VSC module or another fan fails.

Installation

The procedures in this chapter assume the installation site meets the ac power requirements and operating limits listed in Appendix A.

Installing RAID in a Cabinet

Attaching the Slot Matrix Label

Three sticky-backed labels are shipped with the storage chassis: a rack slot matrix diagram showing the disk drive module locations, and two sheets of stickers for identifying disk modules. Attach the rack slot matrix to your storage chassis so it is visible. Save the two sheets of stickers for the person configuring the disk modules into physical disks.

Mounting RAID in a Cabinet

You can mount RAID in a standard 19-inch cabinet using the hardware mounting kit, which is supplied with the storage chassis.

WARNING: Since the RAID chassis weighs a minimum of about 46 kg (101 lbs), installing it in the cabinet requires at least two people.

WARNING: Before opening the cabinet to install RAID, follow the cabinet manufacturer’s recommendations for powering down the cabinet.

RAID Instructions 2-1

Chapter 2 Installation

To install RAID in a cabinet

1. If you want to lessen the weight of the chassis, remove disk modules from the chassis

CAUTION: If you remove disk modules from the RAID chassis, be sure to label each module and return all the modules to their original locations. Failure to correctly locate the disk modules will result in one or more inaccessible LUNs, and may even make the entire storage chassis inaccessible.

(see Removing a Disk Module in Chapter 3), making sure that as you remove each module, you write on the module’s label the ID number of the slot (A0, for example) from which you removed the module. Black out the lower ten slot postions on the slot matrix label, since these positions are not available on the PRS250.

For the slot ID numbers, refer to the slot matrix label, which you should have just attached to the RAID chassis, or to the following illustration.
