1.1 The SS-1200-FCAL System

1.2 The Enclosure Core Product

The SS-1200-FCAL design concept is ba sed on a sub system toge ther with a set of plug-in modules. T he Salient SS 1200-FCAL subsys tem as supplied comprises:

• Chassis with Backplane installed.

• Power Supply/Cooling plug-in modules, in accordance with your required configuration (see Figure 1–4).

Figure 1–1 The SS-1200-FCAL System

SS-1200-FCAL User Guide

• An Enclosure System Interface/Operators Panel (ESI/Ops) plug-in module (see Figure 1–5).

• Blank plates, as required to complete your required configuration and installation.

• FC-AL Drive Carrier Modules and associated front dummy fascia plates. (See Figure 1–10).

• FC-AL Input/Output Modules. (See Figure 1–11 ).

• A third Power Supply/Cooling Module may be required to support some 10 000 rpm disk drives.

1.2.1 Enclosure Chassis

The chassis consists of two segmented chassis assemblies, constructed from a number of aluminum extruded sections, with a Backplane PCB between them. The chassis assemblies each contain 12 'Bays', each of which accommodates a plug-in m odule (lar ger module s can be acc ommodate d using mult iple bay spac es). The B ackplane PCB provides logic level signal and low voltage power distribution paths. A SS-1200-FCAL chassis is shown in

Figure 1–2 and Figu r e 1– 3 .

• 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 r a ck mo unt configuration).

• A 4 x 3 Chassis fitted with 19 inch Rack mounting features enables it to be fitt ed to standard 19 inch racks. It uses 4EIA units of rack space.

sizes of blank plate available:

– Single bay Rear blank pla te s – 1x2 bay Rear blank plat e s – 1x3 bay Rear blank plat e s

Warning Operation of the Enclo sure with

ANY

blank plates or rear modules mis sing will disrupt the a irflow

and the drives will not receive suffici ent coolin g. It is

ESSENTIAL

that all rear apertures are filled

before operating the unit.

1.3.6 Multiple Power Supply/Cooling Modules

If you have two or three Po wer Supply/Coo ling modules fitted, th ey operate togeth er. If one fails the ot hers maintain the power supply and cooling while you replace the faulty unit.

Module replacement should only take a few minutes to perform but must be completed within 20 minutes from removal of the failed module. Alternatively, if there is no replacement module available, a blanking plate could be fitted after removing the faulty module.

Note Three Power Supply/Cooling modules must be fitted if you are installing

drives consuming more than 21 watts (operational), e. g. 10 000 rpm 9GB HH drives.

1.3.7 Visible and Audible Alarms

The functional modules have ass oci ated status LEDs. The ESI/Ops Panel shows a consolidated s tatus for all modules.

LEDs show constant green for good or positive indica tio n and fla s hin g gree n/r ed if non-c riti cal co nd iti on s exist. Constant Amber LEDs indicate there is a fault present within that module.

The ESI/Ops Panel also incorporates an Aud ible Alarm to indicate when a fault state is present and also an Alarm Mute push-butt on.

Warning The Power Supply/Cooling module is not an operator removable part. It must only be removed by

a qualified service engineer who has knowledge of the hazards present within the module.

2.2.1 Enclosure Bay Numbering Convention

The enclosure bay numberi ng 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 hi gh (in the rack mount configuration).

The SS-1200-FCAL su bsystem is housed in a 4 x 3 enclosure, i.e. 4 bays wide by 3 bays high. The fron t 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 pan el should be installed in rear bay 3 /1 (top, middle row, when viewed from the rear).

2.3 Installation

Caution The SS-1200-FCAL Enclosure w ith all its componen t parts in stalled is too heav y for eas y installa tion into

a Rack cabinet. The following procedures describe the installation of the SS-1200-FCAL enclosure and highlights any critic al co-r equisite re quirement s and good handling p ractices which we e ncourage you t o follow so as to ensure that a successful installation is achieved in the easiest manner.

Warning Ensure that you have checke d and fitted a suita ble 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

4.5.1 System Faults

Note See also Section 4.5.5.

Symptom Cause Action

1 The SYSTEM LED will

illuminate AMBER

2 Audible Alarm sound

The ESI processor has detected an internal fault (e.g. failure of an internal communications path)

1 Check for other AMBER LED

indications on the Power Supply /Cooling modules. If there is a PSU error present there may be a communications problem with that Power Supply/Co oling module. Remove and then re-fit the m odule, if th e problem persists then change the mod ule.

2 Check for other AMBER LED

indications on the drives carriers. If none are evident then there may either be an ESI processor problem or a Backplane problem.

3 Change the ESI/Ops Panel module (see

4.9.2).

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 temp erature.

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 ca used by higher ambient temperatures 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 mini mum 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.

1.5 FC-AL Configurations

Important Please refer to the SS-1200-FCAL Drive Carrier Installation guide for information on FCAL drive

configurations.

1.5.1 FC-AL Internal Loop Structures

The SS-1200 4 x 3 FC-AL enclosure has an internal connection structure as shown in Figure 1–3. Connection to the 2 internal loops is achieved via two rear mounted plug-in, Loop Resiliency Circuit (LRC) I/O modules in Bays 3/2

Figure 1–2 FCAL LRC IO Module

Installation

and 3/3 which contain Port Bypass Circuits (PBC) that provide loop resilien cy i n the event of unplug ged or failin g drives.

Notes 1 Figure 1–3 shows the logical routing of the FC-AL interface through the driv e bay s.

2 This figure does not represent the physical wiring of the enclosure.

1.5.2 FC-AL Physical Organi zatio n

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.

FCAL LRC I/O Module

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 acce pt 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 circu its. The function of these circuits is to bypass the loop connections to empty drive bays or any disk drive wh ich is not operating correctly

The two LRC I/O boards enable the du al loops within the enclosure to be maintain ed independen tly of one anoth er, for example: if a Port Bypass fails, that board may be replaced while the other loop is functioning normally.

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 archit ecture and any drive may be hot plugged

during operation.

1.6.1 Connecting Mult ipl e En clo sur es

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 encl osures 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 ho st computer

Installation

Note If the host connections are via a single connector a splitter must be used to separate the Tx and Rx signals. A suitable

cable is available (Part Number.19859-01).

Important Loss of power to any enclosure within such a loop will cause the loo p 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.

1.7 Module Installation

Check for damage especially to the interface connector, do not install if any pins are bent.

1 The modules should be ins ta lle d in r e ar ba ys 3/2 and 3/3 (third from right, middle and bottom bays) of the cha ssi s

(Figure 1–8).

Note Removal Is achieved by pushing the latch to the right and pulling the module out.

1.8 Select ID and AL_PA

The Select ID of each drive bay can be set to one of eight ranges. these settings are read by the disk drives on SEL_0 to SEL_6 lines. The low o rder 4 Bits are fixed accordin g to the po sition of th e drive in the enclosure . The follo wing table shows the relationship between the Bay Position and the Drive Select ID bits:

1.8.1 Selecting Alter na te Sel e ct ID Ra nge s

A Range switch is located on the rear of the L RC I/O mo dule

The Drive Select ID bits, and hence the Arbit rated Loop Physical Address (AL_PA) range, can be changed by setting the Range switch as follows:

Important Although there is a Range Switch fitted to each module, only the switch located on the

Upper

module will be active. This is indicated by the LED on the rear of the LRC I/O module, see Figure

1–5.

Arbitrated Loop - Physical Address (AL_PA)

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 allocat ed du rin g loop ini tia liz a tion . The Soft Address mode is selected by setting the 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.

Table 1–1 shows the hexadecimal AL_PA values selected with each range switch setting.

Moving and Handling

Disk drives are very susceptible to physical shock but damage may not be immediately obvious. Please observe the following precautions before moving and handling the enclosure :

• Always spin down drives prior to removing from the enclosure.

• If the Salient enclosure has been inst alled in a 19 i nch rack which is to be mo ved, remo ve all d rives a nd other plug-in modules and repackage before transporting them separately.

• Keep all plug-in modules packaged to protect them until they are required for installation

• Take care not to drop any of the plug-in modules or strike them onto a hard surface.

Data Security

• Power down your host computer and all attached peripheral devices before beginni ng installation.

• Each Salient enclosure contains up to 12 removable disk drive modules. Disk drives are fragile. Handle them with care, and keep them away from strong magnetic fields.

• All the supplied units and blanki ng plates must be in place for the air to flow correctly around the encl osure and also to complete the internal circuitry.

• If the subsystem is used with plug-in units or blank ing plates missing for more than a few minutes, the enclosure can overheat, ca using power failure and data loss. Such use may also invalidate the warranty.

• If you remove any drive module, you may lose data.

– If you remove a drive module, replace it immediately. If it is faulty, replace it with a module of the same

type and capacity

• Ensure that all drive modules are removed from the enclosure before attempting to handle or move the rack installation.

• Do not abandon your ba c ku p routines. No system is completely foo l proof.

Installation

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-12 00FCAL storage subsystem which utilizes a FC-AL interface with the host computer system.

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 modul e comprises a hard disk, of 4.55Gb or 9.1Gb

capacity, mounted in a carrier. Each drive bay will house a single 1.6 inch high, 3.5 inch disk drive in its carrier.

Figure 1–1 SS-1200-FC-AL Enclosure with Drive Carrier Modules installed

FCAL Drive Module

The following disk drives have been qualified for use with the SS-1200 series enclosure:

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

1.1.1 Drive Carrier Modules

Each disk drive is enclosed in an extr 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 functions:

• Camming of carrier into and out of drive bays.

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

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

1.1.1.1 Drive 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.

Installation

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 disable 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 fam ili ar with the configuration 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:

• All SS-1200-FCAL enclosure drive bays must be filled with either a drive 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 a re only a limited numbe r of drives or PSUs fitted then th ey 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 Bay s 1/1 thr o ugh 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 give s the smoothest loading to the power system. The maximum nu mber of drives which can be started concurrently 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 Table 1–1, then the drives should be started in a staggered sequence at approximately 12 second intervals.

FCAL Drive Module

1.2.3.1 Overload Shutdown

In order to protect against overload due to incorrect configuration, the enclosure will shutdown if more than 8, 10 000 rpm, 9Gb FF drives (drive type 3, i.e. drives with operatio nal power >22 watts) are installe d with only 1 Power Supply/Cooling module active.

1.2.3.2 Drive 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 re fer to the SS-1200

Developer’s Guide for details of the SCP.

Note Operation of the enclosure/d r ives 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.

Installation

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 Enclosure .

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 exi sting backup schedule. It is advisable to store your backup media in fir eproof containers.

How often should I backup?

If you do not have a backup schedule yet, some typical minimum requirements 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.

• 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.

Troubleshooting

Chapter 2 T roubleshooting and Problem Solving

2.1 Drive Module Faults

Disk drive status is monitored by a Green LED and an Amber LED mounted on the front of each Drive Carrier Module, providing the following indications:

2.1.1 Front Dummy Fascias

Front dummy fascias must be fitted to all unused drive bays to maintain a balanced air flow.

Important If any bays are not filled with either a drive or fascia the System LED on the ESI/Ops Panel will

flash.

2.1.2 Auto Start Failure

Unless otherwise selected at installatio n time, all drives in the enclosure should 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 has b een fitted to th e ESI/Ops Panel mod ule during installatio n, thus disab ling the drive auto start function.

• There is a power problem (An alarm and power fault ind ication 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 Hardwa re F ault s

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

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 either 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 subsystem is use d with modules or blank ing plate s missing for more than a few minutes, the enclosure can overheat, c ausing power f ailure and data loss . Such use ma y also invalidate the warranty.

2.3 Continuous Op erat ion During Rep lacemen t

Depending on how the SS-1 200-FCAL storage subsystem is set up, if a disk drive mo du le fails, it can normally be 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 en closure.

Warning Observe all conventional ESD precautions when handling SS-1200-FCAL modules and

components. Avoid contact with backplane components and module connectors, etc.

2.4.1 Removal and Replacement

Caution Drive spin down

Damage can occur to a drive if it is removed while still spinning. If possible use the operating system to spindown the drives prior to removal. If this is not possible we recommend that you perform all steps of the following procedure to ensure that the drive has stopped prior to removal:

1 Release the Handle by pressing on the small indentation area on the left of the carrier fascia.

Note The anti -tamper lock must be off.

2 Gently withdraw the module approximately 1 inch (25mm) and wait 30 seconds.

3 Withdraw the module from the drive bay and fit a replacement module in accordance with the instructions in Section

1.3, ”Modul e Installation”, on page 4.
