on page 8 for details of the LED status conditions.

separately. To replace the Ops panel, you must replace the entire enclosure.

CHAPTER 1: Introduction

Caution

The Ops panel is an integral part of the enclosure assembly and cannot be replaced

Alarms

Enclosure replacement should only be performed by trained personnel.

Visible alarms

The functional modules have associated status LEDs. The Ops panel shows a consolidated status for all modules. LEDs show constant green or blue to indicate good or positive status. Constant or flashing orange LEDs indicate the presence of a fault within that module.

LED State Description

Power On Co nstant green Good or posit ive status System Fa ult Constant orange: fault present Indicates a problem with a power supply, cooling, or

controller module. For more information, see the tables in “Power supply module LEDs” on page 13,

“Cooling Module LED” on page13, and “Controller module LEDs” on page15.

Logical Fault C onstant orange: fault present Indicates f ailure of a dr iv e module. Th e failing module

is indicated by the Fault LED. For more information, see the table in “Drive carrier m odul e faults” o n

page 16.

Box Identity Constant bl ue: en closure ident ity You can light this LED through the management

interfaces to indicate which enclosure requires servi ce act ion s.

See “Ops panel LEDs” on page8 for a description of the Ops panel LED states.

Audible alarms

The Gateway E-842R enclosure includes an audible alarm which indicates when a fault state is present. The following conditions activate the audible alarm:

• Fan fau lt

• Voltage out of range

• Over temperature

• Thermal overrun

• Syste m fau l t

• Logi ca l Fa ul t

• Power supply module fault

When the audible alarm sounds, you can mute it b y pressing the Alarm Mute button on the front panel. For more information, see “Audible alarm mute” on page 16.

The plug-in module s

A Gateway E-842R enclosure requires the following modules for normal operation:

• Two 350 W AC power supply modules.

• One cooling module.

• One or two controller modules.

• As many as 12 drive carrier modules.

• Dummy drive carrier modules, as required.

www.gateway.com

Important

No drive bays should be left comple tely empty. Dummy carriers or bl ank modul es

must be installed in all unused bays.

AC po wer suppl y module

Two, 100V-260 VAC 350 W power supply modules are supplied and mounted in the back of the enclosure as part of the enclosure’s core product.

Power supply module input voltage operating ranges are nominally 115V or 230V AC, selected automatically.

CHAPTER 1: Introduction

T wo LEDs mount ed on the r ear panel of the pow er supply module indicate the status of th e module:

Multiple power supply modules

In order to maintain the appropriate airflow, you must always operate the Gateway E-842R with two power supply modules installed. The two power supply modules operate together so if one fails, the other maintains the power supply and cooling while you replace the faulty module.

Module replacement should only take a few minutes to perform but must be completed within 10 minutes from removal of the failed module.

Cooling module

The cooling module provides system cooling, thermal monitoring, and control functions. System airflow is from the front to the back of the enclosure:

Power On & OK (Green)

Off Off No AC power (either power supply module) Off On No AC power (this power supply module only)

On Off AC present, power supply module on and OK On On Power supply module fan fault

Module Fault (Orange)

Status

Power supply module fault (over temperature, over voltage, over cur r e nt, or power supply module fan fail)

• Cooling air passes over drives and through the midplane to a central air passage.

• The cooling module pulls air from the air passage and from the controller modules.

Important

The system must be operated with a low pressure rear exhaust installation (back pressure created by rack doors and obstacles not to exceed 5 pascals (0.5mm water g au ge) ) .

• The power supply modules pull cooling air fr om t he air pass age at the back of the enc lo sure .

www.gateway.com

The module has an orange Cooling Module Fault LED.

LED status is described in the following table:

Module Fault (Orange) Status

Off Enclosure On - Fan OK On Cooling module fan failure

module OK lights

Contr oller module

CHAPTER 1: Introduction

Caution

Operation of the enclosure with any modules missing disrupts the airflow and the drives do not receive sufficient cooling. All openings must be filled before operating the enclosure. When only one controller module is installed, a blank m odule mu st b e ins talled in the vacant controller module slot at the rear of the enclosure to maintain airflow and ensure correct operation.

Important

Do not mix Disk I/O modules and RAID Controller modules in the same enclosure. Disk I/O modules are only installed in the expansion enclosure and RAID Controllers are only installed in the RAID enclosure.

One or two controller modules (depending on your configuration) are supplied and mounted in the back of the enclosure as part of the Gateway E-842R enclosure core product.

The plug-in controller modules have been designed for integration into the enclosure, providing external FC cable interfacing with the host computer system.

The backplane incorporates a connection to each of the SAS ports within the controller modules. The controller module’s internal processor monitors error conditions on each disk drive port.

Processors housed on the controller modules prov ide enclosure management interfac ing to devices on the backplane, power supply module, controller module, and Ops panel to monitor internal functions. These processors operate in a dual active configuration to allow failover.

The module incorporates LED indicators. For the location of the LED indicators, see “Controller

module LEDs” on page 8.

External ports

The RAID controller module has the following external ports:

• Two external (host) SAS ports that allow for fitting of Small Form-Factor Pluggable (SFP)

modules, with auto-bypass at the output. Either or both of these SFP ports can be used to provide connection to the host controllers. Each host port operates at 3 Gb/s, giving an effective speed of 6 Gb/s. These ports are also backwards compatible with 2 Gb/s hosts.

• An SAS expansion port suppor ts a s man y as four expansion enclosur es t hr ough an SFF-8470

connector.

www.gateway.com

• An RJ45 10/100BaseT Ethernet port lets you connect the controller to a network to enable

out-of-band management and monitoring using the embedded StorView GUI software.

Only shielded, Cat 5 (or better) cables should be used for connection to the

Ehternet port for EMC performance.

• There is also an RS232 socket which provides an alternative user interface to the RJ45

connector.

Caution

Although the RS232 port is similar in appearance to a USB port, it requires a

special cable and you should not attach a USB cable to it.

The recommended configurations are shown in “Ethernet connection” on page 24 and “Enclosure

cabling - multiple enclosures” on page25.

StorView Management software

The StorView Storage Management software which is embedded in the controller module is a full-featured, graphical, HTML-based software suite designed to configure, manage, and monitor the controller module storage solution. T he module is configured w i th a base IP address t o l et you connect to it. See “StorView Storage Management software” on page29 or the Gateway E -842R StorVi ew Sto rag e Ma nag emen t Soft wa re User Gui de for further information.

CHAPTER 1: Introduction

Batt ery module

Each controller module assembly includes a removable battery module (for the location, see

“Controller module” on page8). The battery module contains a replaceable Li-Ion battery pack,

as shown i n the f ol low ing illu str ation. T he bat t ery pack pr ot ec ts the cach e cont ents if th e A C pow er fails. You can check the amount of battery time available through the Management Interface. The amount of time available is dependent on the amount of cache in the system.

See “Battery mo dule” on pag e 24 for removal and replacement procedures.

Disk I/O module

The expansion enclosure houses one or two Disk I/O modules. They provide the drive expansion for the RAID enclosure . When expanding the sy stem, y ou may add up to f our expansion enclos ures. This will give you a total of five enclosures including the RAID enclosure. A fully loaded system will provide a total of 60 disk drives.

I/O modules are only installed in the expansion enclosure and RAID Controllers are only installed in the RAID enclosure.

Processors housed on the Disk I/O modules provide enclosure management and an interface to the devices on the backplane, PSU, Disk I/O module and Ops panel, which monitor internal functions. These Disk I/O module processors operate in a master-slave configuration to allow for failover.

The enclosure may be configured with either one or two modules. If only one Disk I/O module is installed, a blank module must be installed in the unused bay.

Each SAS connector has four LEDs adjacen t to the connector. The LEDs indica te I/O activity on that specific SAS port lane where each port has four lanes.

Driv e carr ier module

The drive carri er module comprises a hard disk mounted in a carrier . Each dri ve bay hou ses a single, low profile, 1.0-inch high, 3.5-inch form-factor disk drive in its carrier. The carrier has mounting locations for SAS or SATA drives.

The front cap also supports an ergonomic handle which provides the following functions:

• Inserting the carri ers i nto the drive b ays

• Removing the carriers from drive bays

• Positive “spring loading” of the drive/backplane connector

• An anti- tamper lock op erated by a torx-socket type key

CHAPTER 1: Introduction

Drive status indicat ors

Each drive carrier has two LEDs, an upper (green) and lower (orange). In n ormal operation the green indicator is ON and flickers as the drive operates. The orange indicator is only ON i f there is a drive fault. If the green LED is OFF when the orange LED is ON, a power control circuit failure is indicated.

Anti-tamper locks

Anti-tamper locks are installed in the drive carrier handles and are accessed through the small cutout in the latch section of the handle. These locks are provided to disable the normal “pinch” latch action of the carrier handle.

Dummy ca rrier mo dules

Dummy carrier modules are provided for fitting in all unused drive bays. They are designed as integral drive module front caps and must be installed in all unused drive bays to maintain a balanced airflow.

Introduction

Caution

When connecting the enclosure, use only the power cords supplied or cords which

match the specification quoted in “Specifications” on page29.

This chapter e xplains ho w to install your enclosure int o a n industry-standard, 19-inch rack cabinet and configure the enclosure sub-system.

Planning y our installation

Caution

Blank modules or dummy carrier modules MUST be installed in ALL unused bays or

the enclosure may overheat.

Befor e you begin installation, yo u should become familiar with the con f iguration requirements of your enclosure , detailed in the f ollow ing table. The corr ect posi tions of each of the optional plug-in modules are shown in the illustration. See “Ethe rnet connec tion ” on p age24 and “Enclosure cabling

Important

Drive carrier modules must always be installed in drive locations 1 and 12. This is the minimum configuration required for the system to operate and provide SES Management Services.

The enclosure driv e bay numbering conv ention is shown in the illustration on page16. A drive bay is defined as the space required to house a single 1.0-inch high, 3.5-inch disk drive in its carrier module.

Driv e carrier conf iguration

Important

Before you begin installation, you should become familiar with the configuration requirements of your enclosure. There must be a drive present in drive locations 1 and 12 to enable SES communications to operate. Installing drives in both of these bays provides redundant SES communication paths.

When planning your system configuration, remember that all enclosure drive bays must be filled with either a drive carrier or dummy drive carrier module. No bays should be left empty.

Enclo sure installation procedur es

Warning

An enclosure with all component parts installed is too heavy for a single person to safely install alone into a rack cabinet.

The following procedures describe the installation of an enclosure and highlight any critical requirements and good handling practices you should follow to ensure a successful installation.

Caution

Make sure that you wear a suitable anti-static wrist or ankle strap and observe all conven ti o nal ESD p recautions when han dl ing modules and compone nts. Avoid c on tact with such things as backplane components and module connectors.

CHAPTER 2: G etting Sta rted

Preparing the sit e and host s erver

Important

The E-842R system supports most of the widely used operating systems. However deployment on M ic r osoft Windows requires t he .i nf dri v e r fil e whic h i s found on the Gat eway External Storage CD (ESCD). (For Windows Servers, insert the ESCD and install the .inf file.)

Before you begin, make sure t hat the site where you intend to set up and us e your storage system has the following:

• Standard AC power from an independent source or a rack power distribution unit with a

UPS (universal power supply).

• A host computer with a standard Fibre Channel HBA (host bus adapter) with the latest BIOS

and drive rs. Follo w the instr uction s pro vided wit h y our HBA and inst all the HBA an d its dri ver software, if necessary.

Unpacking t he enclosur e sy stem

The package contents and unpacking procedure are outlined in the following illustration. The accessory box contains the AC power cord(s), a serial communication cord, and the software

and the Gateway External Storage CD (ESCD). The accessory box insert contains the adjustable rail slides and hardware parts to rack mount the enclosure.
