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.

Important

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.

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.

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.

Rac k installation prer equisit es

The enclosure is designed for installation into an industry standard, 19-inch cabinet, capable of holding the unit.

• A minimum depth of 28 inches (700 mm) from the front flange to the back metalwork

(excludes back cabling).

• Up to 70.5 lbs (32 kg) per enclosure, depending on configuration.

• A minimum gap of 1 inch (25 mm) of clearance between the rack cover and the front of the

drawer, and 2 inches (50 mm) of rear clearance between the back of the drawer and the back of the rack is recommended, in order to maintain the correct airflow around the enclosure.

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

Rack mounting rail kit

A set of mounting rails is a vailable for us e in 19-inch rac k cabi ne ts. T he s e r ails have been designe d and tested to handle the maximum enclosure weight and to ensure that multiple enclosures may be installed without 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.

Contact Gateway Customer Care to make sure that suitable mount rails are available for the rack you are u si ng .

Known issues and limitations

The following issues and limitations are present in the current release of the Gateway Hardware Provider for VDS:

• Flashing of drive LEDs cannot be turned off - they can only be set to flash for a specific time

period.

• The following limitations relate to the Se tFriendlyName method in the

“IVdsSubSystemNaming” object:

• The subsy st em cannot be giv en a fr iendl y name until at least one L UN has been cr eat ed.

• If the subsystem is renamed without any other configuration being present, the

subsystem will retain the default name.

• If the subsystem has been renamed, then all L UNs are deleted, the subs y st em name will

revert bac k to the de faul t n ame .

• When using the Extend method in the “IVdsLun” object, if there is insufficient space on the

existing array, a whole new array will be created in the background on which to expand the LUN.

Existing arrays cannot, in themselves, be extended. This has the following implications:

• RAID 5 arrays have to be extended by a minimum of 3 drives.

• RAID 1 arrays have to be extended by an even number of drives.

If there are an insufficient number of drives or if an incorrect number of drives is explicitly specified, an invalid arg umen t error oc curs.

CHAPTER 2: G etting Sta rted

• There are minimum allowable chunk sizes for RAID 0 and RAID 1 arrays (RAID 5 arrays have

no restrictio ns) :

RAID 0:

Number of Drives 1 or 2 3 4 or more Minimum Chunk Size 256K 128K 64K

RAID 1:

Number of Drives 2 or 4 6 8 or more Minimum Chunk Size 256K 128K 64K

10.1.1.7. The first time you start StorView, you need to configure the network settings. On the first startup,

you are prompted for a user name and passwor d. T he def ault user name is admin and the default passwo rd is passw ord. You should change your password to protect your array. See the Gateway E-842 R StorV iew Stora ge Ma na gem ent Soft wa re Us er G ui de for additional information.

P ower do wn

Y ou can turn off t he enclosur e at any time . If cached contents are pr es ent (look at the Cache Acti v e LED on the controller module), they are saved by the internal battery. If the enclosure is left in this state for extended periods, the batteries discharge and the cached data is lost. Therefore, we recommend that you shut down the controller prior to powering off the enclosure, especially if the unit is to be powered down for an extended period. This ensures that the cache is flushed to disc and prevents the battery from being discharged. Discharged batteries may also result in reduced performance when the array is again powered up, because the write-back cache is disabled until the batteries are fully charged.

To power down the enclosure:

1 Shut down the controller through the GUI interface. For more information, see the Gateway

E-842 R StorV iew Stora ge Ma na gem ent Soft wa re Us er G ui de.

2 Disconnect AC power at the power source.

Thermal c ontrol

The Gateway E-842R storage enclosure uses extensive thermal monitoring and takes a number of actions to make sure that component temperatures are kept low and that acoustic noise is min im ized. Ai rfl ow i s fro m fron t to rea r o f th e e nc los ure.

Symptom Cause Action

If the ambient air is cool (below 77°F (25°C)) and the fans are observed to increase in speed, some airflow restriction may be caus ing the internal te mperature rise. Note: This is not a fault condition.

The first stage in the the r mal con trol proces s is fo r th e fa ns to auto ma t ic al ly i nc rea se i n 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 su pplies installed.

■

Check the installation for any airflow restrictions at either the front or rear of the enclosure. A minimum gap of 1 inch (25 mm) at the fron t a nd 2 inch es ( 50 mm ) a t the rear is recommen ded. Check for restrictions caused by dust build-up and clean as appropriate. Check f o r ex ce ssi v e r e-circ ulatio n of h eate d air from the rear to the front. Installing in a fully enclosed rack installation is not recommended. Make sur e t hat all blank module s ar e in stal led. Reduce the ambient temperature.

Hardware faults

Make sure that you have obtained a replacement module of the same type before removin g a ny fault y m od ul e.

Caution

If your Gateway E-842R enclosure is turned on and you remove any module, replace it immediately. If the enclosure is used with plug-in modules, dummy carriers, or blank modules missing for more than a few minutes, the enclosure can overheat, causing power failure and data loss. Such use invalidates the warranty.

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

• All drive bays must have a drive carrier or dummy carrier module installed in order to

maintain a balanced airflow.

• All of the supplied plug-in power supply units, electronics modules, dummy carriers, and

blank modules must be installed for the air to flow correctly around the cabinet.
