2.2.1 Enclosure Bay Numbering Convention

The enclosure bay numbering convention is shown in Figure 2–1. A Bay is defined as the space required to house

a single 1.6" high 3.5 inch disk drive in its carrier module. e.g. a 1 x 3 bay module would take the space of 1 drive width by 3 drive bays high (in the rack mount configuration).

The SS-1200-FCAL subsystem is housed in a 4 x 3 enclosure, i.e. 4 bays wide by 3 bays high. The front bays are numbered 1 to 4 from left to right, viewed from the front. The rear bays are numbered 1 to 4 from right to left, viewed form the rear. Bays are numbered from 1 (top row) to 3 (bottom row). Module locations are identified from a matrix of the top and side numbers, e.g. the front ESI/Ops panel should only be installed in front bay 1/1 (top left when viewed from the front) while the rear ESI/Ops pa nel should be installed in rear bay 3 /1 (top, middle row, when viewed from the rear).

2.3 Installation

Caution The SS-1200-FCAL Enclosur e with all its compo nent parts in stalled is too he avy for eas y instal lation into

a Rack cabinet. The following procedures describe the installation of the SS-1200-FCAL enclosure and highlights any cri tical co-r equisite re quiremen ts and good handling p ractices which we e ncourage y ou to follow so as to ensure that a successful installation is achieved in the easiest manner.

Warning Ensure that you have che cked and fitted a suitable anti-static wrist or ankle strap and observe all

conventional ESD precautions when handling SS-1200-FCAL modules and components. Avoid contact with Backplane components and module connectors, etc.

2.3.1 Pre-Requisite s

The SS-1200-FCAL Enclosure is d esigned for installation into an industry standard 19 inch cabinet capable of holding the unit.

• Minimum depth 580 mm from front flange to rear metal w ork (excludes rear cabling).

• Weight (35 to 45 kg dependent upon configuration) per enclosure.

• A minimum gap of 25mm (1inch) clearance between the rack cover and front of drawer; and 50mm (2 inches) rear clearance between rear of drawer and rear of rack is recommended in order to maintain the correct air flow around the enclosure.

• The rack should present a maximum back pressure of 5 pascals (0.5mm water gauge).

2.3.2 Rack Mounting R ail Kit

A set of mounting rails is available for use in 19 inch rack cabinets. These rails have been designed and tested to handle the maximum enclosure weigh t and to ensure that multiple SS-12 00 enclosures may be installed with out loss of space within the rack. Use of other mounting hardware may cause some loss of rack space.

The rack mounting rail kit also incorporates a rear hold down mechanism to ensure shock and vibration immunity.

4.5.3 Thermal Control

The SS-1200-FCAL Enclosure uses extensive thermal monitoring and takes a number of ac tions to ensure component temperatures are kept low and also to minimize acoustic noise.Air flow is from front to rear of the enclosure.

1 Any power fault.

2 A fan failure.

3 A thermal condition which

could cause PSU overheating.

1 Check Power On/Off Switch on rear of

Power Supply/Cooling module is switched ON.(not accessible on later models)

2 Check AC Mains Connections to

Power Supply/Cooling module is live.

3 Check PSU Voltage Range selector

switch is correctly set.

4 Disconnect the Power Supply/Cooling

module from mains power and remove the module from the system, Reinstall: if problem persists, replace Power Supply/Cooling Module.

5 Reduce the ambient temperature.

Symptom Cause Action

If the ambient air is cool (below

25 °C) and the fans are observed to increase in speed then some restriction on airflow may be causing additional internal temperature rise.

Note: This is not a fault condition.

The first stage in the thermal control process is for the fans to automatically increase in speed when a thermal threshold is reached. This may be caused by higher ambient temperatur es in the local environment and may be perfectly normal.

Note: This threshold changes according to the number of drives and power supplies fitted.

1 Check the installation for any airflow

restrictions at either the front or rear of the enclosure. A minimum gap of 25mm at the front and 50mm at the rear is recommended.

2 Check for restrictions due to dust build-

up, clean as appropriate.

3 Check for excessive re-circulation of

heated air from rear to the front, use in a fully enclosed rack installation is not recommended.

4 Check that all Blank plates/modules are

in place.

Figure 1–4 shows the two FC-AL loops, these are each routed through indepe ndent LRC I/O cards fitted in the rear

of the enclosure. Either of these may be removed while the other is operating, thus providing fully redundant FCAL operation.

LRC Input/Output Modules are fitted in bays 3/2 and 3/3. Each module includes DB9 connectors for FC-AL attachment, shown in Figure 1–5.

1.6 FC-AL Interface

The (I/O) interface module provides an FC-AL interface via DB9 connectors for copper (Cu) cable connection.The Tx/Rx interface has been wired to accept a Media Interface Adaptor (MIA), enabling the use of optical media

“Daisy chain” connection of multiple enclosures can be accommodated by linking between the FC-AL Tx connector on one enclosure and the Tx/Rx connector on the next enclosure.

Each I/O or Loop Resiliency Circuit board houses Port Repeater chips that re-drive the Fibre Channel signals. Each of the LRC I/O boards also houses a number o Port Bypass circuits. The function of these circuits is to bypass the loop connections to empty drive bays or any disk dri ve which is not operating correctl y

The two LRC I/O boards enable the dual loops within the enclosu re to be mainta ined indepen dently of one ano ther, for example: if a Port Bypass fails, t hat board may be replaced while the other loop is functioning normally.

ID Range

Active

Notes 1 A suitable dual loop host attachment will also be required to use this function.

2 There are no external terminators required with Fibre Channel archi tecture and any drive may be hot plugged

during operatio n.

1.6.1 Connecting Mul ti ple En closures

A daisy chained loop application is used to connect multiple enclosures.

Standard DB9 FC-AL cables are used to link the Tx connector on one enclosure to the Tx/Rx connector of the next and so on for the required number of enclosures in the chain, as shown in Figure 1–6. The loop is completed by linking the Tx connector on the last enclosure in the chain back to the host computer

Important Loss of power to any en clos ure wi thin suc h a loo p w ill ca use the loop to fail. The use of a FC-AL

hub (Figure 1–7) to connect to each enclosure will allow the removal of any enclosure (through

physical removal or power loss) without loss of the entire FC-AL loop.

Arbitrated Loop - Physical Address (AL_PA)

Bay

Upper

Within the FC-AL protocol each device on a loop is allocated a unique Physical Address (AL_PA). This is derived from the Select ID set described above. Please refer to , Table 2–1 for further information. Alternatively a device

may use a Soft Address such that its AL_PA is dynamically alloca te d durin g loo p ini tia liza tion . The Soft Addre ss mode is selected by setting t he Port ID Range switch to 8.

Note If conflicting IDs are selected the FC-AL initialization process will use soft addressing to allocate AL_PAs, this

could make the identification of particular devices difficult.

Chapter 1 Installation

1.1 Introduction

The plug-in FC-AL drive carrier modules desc ribed in this manual has been design ed for integration into a SS- 1200FCAL storage subsystem which utilizes a FC-AL interface with the host computer system.

Installation

The SS-1200-FCAL storage subsystem includes an enclosure with front facing drive bays housing up to 12 plug-in drive carrier modules (see Figure 1–1). The drive carrier module comprises a hard disk, of 4.55Gb or 9.1Gb

capacity, mounted in a carrier. Ea ch drive bay will house a single 1.6 inch high, 3.5 i nch disk drive in its carrier.

This chapter describes the procedures for installing FC-AL drive carrier modules in a SS-1200-FCAL enclosure.

Each disk drive is enclosed in an ext r uded aluminum carrier which provides excellent thermal conduction, Radio Frequency and Electro Magnetic induction protection and affords the drive maximum physical protection.

The cap also supports an ergonomic handle which provides the following function s :

• Camming of car rier into and out of drive bays.

• Positive 'spring loading' of the drive/backplane connector.

• An anti-tamper lock operated by a socket type key.

Figure 1–2 Drive Carrier Module

1.1.1.1 D rive LEDs

Each Drive carrier incorporates two indicators, an upper (Green) and lower (Amber). In normal operation the green LED will be ON and will flicker as the drive operates.

1.1.2 FC-AL Front Dummy Fascias

FC-AL front dummy fascias are provided for fitting in all unused drive bays. They are designed as integral drive module front caps with handles and must be fitted to all unused drive bays to maintain a balanced air flow.

1.1.3 Anti-tamper Locks

Anti-tamper locks are provided to di sable the normal ’Push/Push’ latch action of the carrier handle.

1.2 Planning and Configuring Your Installation

1.2.1 System Configuration

Before you begin installatio n yo u sho uld beco me famili ar with the co nfi gu rat ion requirements of your SS-1200FCAL system.

Please refer to the SS-1200-FCAL Installation/User Guide for information on your overall system configurations.

When planning your system configuration, please remember that:

Installation

• All SS-1200-FCAL enclosure drive bays must be filled with either a driv e carrier, fro nt du mmy fascia or ES I /Ops Panel module (Bay 1/1 only), no bays should be left completely empty.

The correct positions of each of the optional plug-in modules are detailed in the SS-1200-FCAL Installation/User Guide.

1.2.2 Drive Configuration

Important After you have installed the drive carrier modules in your SS-1200-FCAL enclosure, please refer

to the SS-1200-FCAL LRC I/O Module Installation Guide for configuratio n information rele vant to the I/O module and instructions for setting the Drive Select ID bits.

Although it is not essential we recommend that if there are only a limited nu mber of drives or PSUs fitted then they should be located as close together as possible (If for example only 1 PSU and 6 drives are fitted, the PSU should be in rear bay 2 and the driv es in B ay s 1/ 1 through 2/3).

1.2.3 Drive Auto Start

The delayed sequence start is used to start the drives in the enclosure unless the Manual Start Flag (Jumper) is fitted, in which case no drives will start and start up is left to the host computer.

If this is the case then to guarantee maximum redundancy within the system it is important that the host computer starts the disks in a manner which g ives the smoothest loading to the power system. The maximu m number of drives which can be started concurren tly in a 12 drive enclosure are defined in Table 1–1

If there are more than the specified number of drives installed as detailed in Tabl e 1–1, then the drives should be started in a staggered sequence at approximately 12 second intervals.

1.2.3.1 Overload Shutdown

In order to protect against overload due to incorrect configuration, the enclosure wi ll shutdown if more than 8, 10 000 rpm, 9Gb FF drives (drive typ e 3, i.e. drives with opera tional power >22 watts) are installed with only 1 Power Supply/Cooling module active.

1.2.3.2 D rive Type

The drive type information is stored in the enclosure EEPROM. To set this to the required value use the SS-1200 Configuration Program (SCP) which can access this data through the RS232 link. Please refer to the SS-1200

Developer’s Guide for details of the SCP.

Note Operation of the enclosure/drives is unaffected by these settings, with the exception of type 3 drives as described

above.

If the Manual Start Jumper is not fitted (default) then the drives will start in a delayed sequence defined as:12 seconds x module 8 of the SEL_ID of the drive.

4 Remove the key.

De-activation is the reverse of this procedure, that is:

• Rotate the key through 90 degrees in a clockwise direction until the indicator visible in the centre aperture of the handle shows black.

Note A drive carrier cannot be installed if its anti-tamper lock is activated outside the Enclo sure.

1.5 Organizing Backups

You should still make backups. The SS-1200-FCAL subsystem is a safe medium for your data, but no system is completely foolproof.

Continue your existing backup schedule. It is advisable to store your backup med ia in fireproof containers.

How often should I backup?

If you do not have a backu p schedule yet, some typical minimum req uirements for consideration are as follows:

• Initial/monthly: back up all applications and data as soon as you start using the SS-1200-FCAL subsystem, and at monthly intervals afterwards.

Installation

• Daily: back up new and changed data at least once a day. Keep each day’s data for a week.

• Weekly: back up all data at least once a week and start the daily cycle again.

flash.

2.1.2 Auto Start Failure

Unless otherwise selected at installa tion time, all drives in the enclosure shou ld automatically start the ir motors after power is applied. If this has not occurred one of the following conditions may exist/

• The 'Manual start op tion jumper ha s been fitted to th e ESI/Ops Panel m odule during installa tion, thus disab ling the drive auto start function.

• There is a power problem (An alarm and power fault i ndication would normally be active).

• Only 1 Power Supply/Cooling module is fitted in an enclosure with:

– drive Type 3 selected – more than eight drives installed.

A full complement of two Power Supply/Cooling modules are required to auto start. Note: The System LED will flash Green/Amber.

2.2 Dealing with Hard ware F ault s

Warning If the SS-1200-FCAL storage subsystem is powered up and you remove a drive module, replace

2.3 Continuou s Operat ion Durin g Rep lacem ent

it immediately. If it is faulty, replace it with a drive module of the same type and capacity.

All drive bays must be fitted with eithe r an FC-AL Drive Carrie r Module or a front dummy fa scia in order to maintain a balanced air flow.

All the supplied plug-in modules, power sup ply units and blanking plat es must be in place for the air to flow correctly around the Salient enclosure.

If the SS-1200-FCAL subsys tem is used with modules or blank ing plate s miss ing for mo re than a few minutes, the enclos ure can overhea t, causing power f ailure and data loss. Such use may also invalidate the warranty.

Depending on how the SS-1 20 0-F CAL sto rage sub syste m is set up , if a disk d rive m o du le fa ils, it c a n no rmall y b e replaced without interrupting the use of the system.

2.4 Replacing a Modu le

Please see ”Installation” beginning on pag e1. for information on the initial installation of the plug-in modules in

the SS-1200-FCAL enclosure.
