RS-1600/1602-FC-SBD User Guide

1.2 The Enclosure Core Product

The RS-1600-FC-SBD and RS-1602-FC-SBD design concept is based on a subsystem together with a set of plug-in modules. The RS-1600-FC-SBD or RS-1602-FC-SBD subsystem as supplied comprises:

• Chassis and Backplane with integral Operators Panel.(See Figure 1–10)

• Up to 16 FC Drive Carrier modules (See Figure 1–12) Note: There are two versions of the drive carrier available, for RS-1600 or RS-1602 chassis. They

are not interchangeable as the RS-1602 drive carrier is longer (approximately 44mm) than that for the RS-1600 chassis.

• Dummy drive carrier modules.

•Two Power Supply/Cooling plug-in modules, two variants are available:

– .AC, 450W PSU (see Figure 1–5) – -48V DC 450W PSU (see Figure 1–6)

• Two plug-in LRC Input/Output Modules, with integrated 20-port Fibre Channel Switch and optional FC Target SES interface device. These constitute an SBOD (Switched Bunch of Discs) module with1Gb/2Gb external operating speed, optionally known as an SBD module (See

Figure 1–8).

1.2.1 Enclosure Chassis

The chassis consists of a sheet metal enclosure assembly containing a Backplane printed circuit board (PCB) and module runner system. This chassis assembly also includes an integral Operators (Ops) Panel, mounted at the rear.

The RS-1602 series chassis is longer than the RS-1600 series chassis, to accommodate the longer RS1602 variant drive carrier modules but is otherwise identical.

The chassis assembly contains 16 drive bays at the front, each of which accommodates the appropriate plug-in drive carrier module. The 16 drive bays are arranged in 4 rows of 4 drives. At the rear, the chassis assembly contains the integral Ops panel module and four plug-in module bays to house two Power Supply/Cooling modules and two SBD modules.

The Backplane PCB provides logic level signal and low voltage power distribution paths. Figure 1–2 and

Figure 1–3 show front and rear views of a populated chassis respectively.

The chassis is fitted with 19 inch Rack mounting features which enables it to be fitted to standard 19 inch racks and uses 3EIA units of rack space.

• A Bay is defined as the space required to house a single 1.0" high 3.5 inch disk drive in its carrier module. e.g. a 1 x 4 bay module would take the space of 1 drive width by 4 drive bays high (in rack mount configuration).

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

1.3.3 SBD Input/Output Module

The RS-1600-FC-SBD and RS-1602-FC-SBD storage subsystems each include an enclosure with rear facing bays which house two SBD modules. These are Loop Resiliency Circuit (LRC) Input/Output modules with integrated 20-port Fibre Channel Arbitrated Loop Switch.

The plug-in SBD modules have been designed for integration into a RS-1600-FC-SBD or RS-1602-FCSBD storage subsystem, providing external FCAL cable interfacing with the host computer system

The FC-AL Backplane incorporates connection to each of the switch ports within the SBD modules.

At any host port this appears as one FC-AL logical loop.

The SBD module internal processor monitors error conditions on each disk drive port and will automatically isolate device that causes excessive FC errors or cannot communicate correctly. Under these conditions the drive’s amber LED will be set to Flash and the status (2Gb) LED on the SBD module will Flash to indicate which loop the problem has been identified on.

Each disk drive is enclosed in a die-cast aluminum carrier which provides excellent thermal conduction, radio frequency and electro-magnetic induction protection and affords the drive maximum physical protection.

The front 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 torx socket type key.

Two versions of the drive carrier (Figure 1–12) are offered, for installation in RS-1600 or RS-1602 chassis. They are not interchangeable as the RS-1602 drive carrier is longer (approximately 44mm) than that for the RS-1600 chassis.

1.3.4.1 Drive Status Indicators

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

1.3.4.2 Anti-tamper Locks

Anti-tamper locks are fitted in the drive carrier handles (Figure 1–13) and are accessed through the small cutout in the latch section of the handle.These are provided to disable the normal ‘pinch' latch action of the carrier handle.

RS-1600/1602-FC-SBD User Guide

1.3.5 Dummy Carrier Modules

Dummy carrier modules 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 airflow.

1.3.6 Blank Modules

Warning Operation of the Enclosure with ANY modu les missing will disrupt th e airflow and th e drives will

not receive sufficient cooling. It is ESSENTIAL that all apertures are filled before operating the unit. Dummy Carriers and/or Blank modules are available for this purpose.

1.4 Visible and Audible Alarms

The functional modules have associated status LEDs. The Ops Panel shows a consolidated status for all modules.

LEDs show constant green for good or positive indication. Constant Amber LEDs indicate there is a fault present within that module.

The Ops Panel also incorporates an Audible Alarm to indicate when a fault state is present and also an Alarm Mute push-button.

Warning The Ops Panel is an integral part of the enclosure chassis assembly and can only be replaced by

trained personnel.

RS-1600/1602-FC-SBD User Guide

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 1.0" high 3.5 inch disk drive in its carrier module. e.g. a 1 x 4 bay module would take the space of 1 drive width by 4 drive bays high (in the rack mount configuration).

RS-1600-FC-SBD and RS-1602-FC-SBD subsystems are housed in a 4 x 4 enclosure, i.e. 4 bays wide by 4 bays high. The front bays are numbered 1 to 4 from left to right, viewed from the front. Bays are numbered from 1 (top row) to 4 (bottom row). Drive Carrier Module locations are identified from a matrix of the top and side numbers. The rear bays are numbered 1 to 5 from right to left, viewed from the rear

Important Drive carrier module must always be fitted in locations 1/1 (drive 0) and 4/4 (drive 15). This is the

minimum configuration required for the system to operate and provide SES Management Services.

RS-1600/1602-FC-SBD User Guide

4.5.3 Thermal Control

RS-1600-FC-SBD and RS-1602-FC-SBD Enclosures use extensive thermal monitoring and take a number of actions to ensure component temperatures are kept low and also to minimize acoustic noise.Air flow is from front to rear of the enclosure.

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 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 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 modules are in

place.

5 Reduce the ambient temperature.

4.5.5 Thermal Warnings

4.6 Dealing with Hardware Faults

Ensure that you have obtained a replacement module of the same type before removing any faulty module.

Warning If your RS-1600-FC-SBD or RS-1602-FC-SBD subsystem is powered up and you remove any

module, replace it immediately. If the subsystem is used with modules or module blanks missing for more than a few minutes, the Enclosure can overheat, causing power failure and data loss. Such use will invalidate the warranty.

• Replace a faulty drive with a drive of the same type and capacity.

• All drive bays must be fitted with a Drive Carrier module or a dummy carrier module in order to maintain a balanced air flow.

• All the supplied plug-in power supply units, electronics modules and blank modules must be in place for the air to flow correctly around the cabinet.

4.7 Continuous Operation During Replacement

Depending on how the subsystem is set up, if a disk unit fails, it can normally be replaced without interrupting the use of the system.

In addition, each enclosure contains two Power Supply/Cooling modules, either of which can maintain power and cooling to the subsystem while the other is replaced.

Symptom Cause Action

1 ALL AMBER LEDs

on the Ops Panel and on ALL drive bays illuminated flash.

2 Audible Alarm

sounds almost continuously and cannot be muted.

At a higher threshold than the Thermal Alarm (this should already have been activated).

OR - All fans have failed.

OR - Only 1 fan operating and the internal temperature is 40° C or above.

1 Check for airflow restrictions.

2 Check Power Supply/Cooling

module faults.

3 Check for excessive local

temperatures.

4 Switch Off immediately.

Glossary

In glossary definitions, italics are used for items defined elsewhere in the glossary and bold is used for the items shown in brackets after the main heading of the entry.

ASCII American Standard Code for Information Interchange. A 7-bit binary code (0's, 1's) used to represent letters, numbers, and special characters such as $,!, and /. Supported by almost every computer and terminal manufacturer.

Attribute Setting that controls access to a specific file. Often used to protect important files (such as the Registry files) from accidental change or deletion. Set using the ATTRIB command in MS-DOS.

Backplane A printed circuit board incorporated in the chassis assembly to provide logic level signal, and low voltage power distribution paths.

Bay The slot that a unit or media device fits into.

Byte A group of binary digits stored and operated upon as a unit. A byte may have a coded value equal

to a character in the ASCII code (letters, numbers), or have some other value meaningful to the computer. In user documentation, the term usually refers to 8-bit units or characters. 1 kilobyte (K) is equal to 1,024 bytes or characters; 64K indicates 65,536 bytes or characters.

Cable Throughout this RS-1600-FC-SBD and RS-1602-FC-SBD user guide this term is used in accordance with the preferred US context of: “an insulated flexible electric wire used for the transmission of data signals between computer equipment.”

Note: Cable is UK preferred terminology for either a power cord or a data cable.

Character A representation, coded in binary digits, of a letter, number, or other symbol.

Characters Per Second A data transfer rate generally estimated from the bit rate and the character

length. For example, at 2400 bps, 8-bit characters with Start and Stop bits (for a total of ten bits per character) will be transmitted at a rate of approximately 240 characters per second (cps).

Chassis A sheet metal enclosure incorporating a Backplane Printe d Circuit Board and module runner system. The chassis contains a number of 'Bays', each of which can accommodate a plug in module. There are sixteen drive carrier bays at the front and five bays at the rear which house two power supply/ cooling modules, two SBD modules and also the Ops Panel.

Configure To set up a hardware device and its accompanying software.

Data Communications A type of communications in which computers and terminals are able to

exchange data over an electronic medium.

Disk (drive, carrier, module) A FC disk drive mounted in a carrier. You can have up to sixteen disk drive carrier modules in each RS-1600-FC-SBD or RS-1602-FC-SBD enclosure.

Enclosure The chassis assembly which houses the plug-in modules that make up an RS-1600-FCSBD or RS-1602-FC-SBD storage subsystem.

ESI/Ops module A unit used to monitor and control all elements of the Enclosure. The ESI/Operators (Ops) panel is supplied as an integral part of the RS-1600/1602 series Enclosure core products

RS-1600/1602-FC-SBD User Guide

Hot plugging A device with the capability of being connected to a subsystem without interrupting the power supplies to that subsystem.

Hot swap Hot swapping is the term used for manually swapping a failed disk unit with a replacement while an RS-1600-FC-SBD or RS-1602-FC-SBD subsystem is in normal use.

Hz (Hertz) a frequency measurement unit used internationally to indicate cycles per second.

Initialize To prepare a hardware device for use.

LED Light Emitting Diode. A small light displayed on the cabinet, disk units and power supply units.

LRC I/O module (SBD module) A plug-in module providing FC-AL channel external cable interface

with 16 FC drives, containing an integrated 20-port Fibre Channel Switch and optionally a Target SES interface device. These produce an SBOD (Switched Bunch of Discs) module with1Gb/2Gb external operating speed, known as SBD modules. The SBD module provides enhanced diagnostic status for FC ports and improved performance through its switching function.

Module (power supply, drive, SBD) A module is a power supply, disk drive or electronics unit held in a carrier that plugs into a bay inside the enclosure. An RS-1600-FC-SBD or RS-1602-FC-SBD enclosure can contain sixteen drive modules, two power supply/cooling modules and two SBD (I/O) modules.

Operating system The software running the host computer. For example, on PCs it is often Windows 2000, Windows NT or Windows XP and on Hewlett-Packard machines it could be HP-UX.

Parallel Transmission The transfer of data characters using parallel electrical paths for each bit of the character, for example, 8 paths for 8-bit characters. Data is stored in computers in parallel form, but may be converted to serial form for certain operations. See Serial Transmission.

Power Cord Throughout this RS-1600/1602-FC-SBD user guide this term is used in accordance with the preferred US context of: “an insulated flexible electric wire fitted with connectors at each end and used for the transmission of electrical power to computer equipment.

Protocol A system of rules and procedures governing communications between two or more devices. Protocols vary, but communicating devices must follow the same protocol in order to exchange data. The format of the data, readiness to receive or send, error detection and error correction are some of the operations that may be defined in protocols.

Redundant Not essential.

Serial Transmission The transfer of data characters one bit at a time, sequentially, using a single

electrical path. See Parallel Transmission.
