Chapter 1 - Getting Started

Components

This section provides a description of each of the major components that
comprise the imageRAID Series Storage System.

Front Bezel

The front bezel houses the Status LEDs, Drive LEDs, and alarm reset button. When
removed, the user has access to the disk drives. The front bezel can be installed or
removed without interruption to system activities.

Embedded within the front bezel is the electronic package that provides the
communication with the SES controller. The SES controller manages the signals to
the front panel through a smart interface. Power is applied to the front bezel
through the interface edge connector, where a control circuit monitors the bezel
for proper connection. When the bezel is properly installed and power is applied
to the enclosure, the bezel is immediately energized.

Refer to “Control and Monitoring” on page 18 for details on the monitoring
functions.

Removable Front Bezel

To remove the bezel and gain access to the disk drives, use a Phillips screwdriver
to release both bezel fasteners, then grasp and remove the bezel. The fasteners
rotate one-quarter turn clockwise to lock and counter-clockwise to unlock.

Chapter 1 - Getting Started

AC Power

The power system consists of two 350-watt hot-pluggable power supplies, each
with independent AC power cords and cooling fans. This power system provides
the enclosure with “N+1” redundant power. Each power supply has auto-switching
circuitry for use with either 100V or 240V AC systems.

Power Supply

Power is applied to the enclosure by pressing each of the two power supply
On/Off switches to their “On” position. A Power On LED located on each power
supply will be illuminated indicating that AC power has been applied. The front
bezels’ Power On LED will also be illuminated indicating that power has been
applied.

Each power supply also incorporates an amber general Fault LED. If the power
supply is installed and power is not applied to the power supply or the power
supply cooling fan fails, the Fault LED will illuminate, along with an audible alarm.

The front bezels’ Power Supply Status LED will illuminate green when both
power supplies are on and operating normally. If only one power supply is
operational, the Power Supply Status LED will be illuminated amber.

Each power supply has an AC Power Cord Module. The module has a power
cord bale incorporated into the design to secure the power cord once it has been
properly inserted. The bale prevents inadvertent disconnects.

AC Power

Chapter 1 - Getting Started

Cooling Fan Module

The cooling system consists of two high-performance (80-CFM) cooling fans

mounted in a single fan module which slides into a bay at the rear of the

enclosure. The design of the fan module provides for an easy-to-install user-

replaceable component in a live environment without interruption of service.

If any one fan should fail, cooling redundancy and efficiency are degraded. The

cooling fans and enclosure temperature are constantly monitored by the SES

processor for fault conditions. In the event of a fault condition the front panel Fan

Status LED will change from a green state to a solid amber state in the case of a fan

failure, or to a blinking amber green state in the case of an over-temperature

condition. In both cases an audible alarm sounds. The SES processor will also

provide notification data to monitoring software, such as StorView.

WARNING:

Do not operate the enclosure for extended periods of time (greater

than 5 minutes) with the cooling fan module removed.

Jumpers JP1 (Fan 0)
and JP2 (Fan 1)

Cooling Fan Module

The enclosure has temperature sensors in three different areas, the drive bay, the

imageRAID Controllers, and the power supplies. There are several steps the storage

system performs to prevent component damage due to over temperature

conditions.

Cooling Fan Module

Chapter 1 - Getting Started

If the drive bay area reaches a temperature of 50°C (122°F) an audible alarm will

sound, the front panel Fan Status LED will toggle amber green, and the monitoring

software will post a warning message. These notifications give the user a warning

that some condition is causing the enclosure temperature to exceed the preset

value, and an action is required by the user to determine the cause and take

corrective measures. It may be due to a blockage of air flow or a low fan speed.

If any controller reaches a temperature of 65°C (149°F) an audible alarm will

sound, the front panel Fan Status LED will alternate amber and green, and the

monitoring software will post a warning message. If the temperature on any

controller continues to rise and reaches 71°C (159°F), the controller will flush its

cache and shutdown. If it is the only controller (Simplex mode) or the only

remaining controller (surviving controller from a failed over operation) then the

controller will also spin down the disk drives at this temperature.

If any power supply reaches 85°C (185°F) the power supply will shut down.

The SES Controller card has a firmware-based VT-100 interface which provides an

option to manage fan speed. This option provides a whisper mode fan operation

for noise sensitive environments. When enabled (default), and based on a set of

conditions, the software will manage the cooling fans RPM speed to maintain the

enclosure temperature while minimizing noise levels. Refer to “Enclosure Fan

Speed Control” on page 122 for more details on using this option.

6

Cooling Fan Module

A manual override of the fan speed control is available for special circumstance

environments. Referring to the illustration on the preceding page, two jumpers are

provided on the fan module printed circuit board to override the software control

of the fan speeds. This hardware setting routes full power voltage to the fans for

maximum operational speed, which is greater than the maximum speed set by the

automatic software control. This configuration is normally used when fan speed

noises are not an issue, and the ambient operating temperature is at or above 30°C

(86°F), thus ensuring that maximum available cooling is being provided.

The jumpers JP1 and JP2 by default are offset, which enables the automatic fan

speed control. The jumper JP1 controls Fan 0 and JP2 controls Fan 1. Placing the

jumper on both pins for each jumper will override the automatic setting and

configure the fans to maximum power.

SES Controller Card

Chapter 1 - Getting Started

WARNING:

The SES Controller card is NOT HOT SWAPPABLE. You must POWER

DOWN the enclosure prior to removing or inserting this card.

The

SES Controller

card provides the built-in environmental and system status

monitoring. It also houses the switches for setting the drive spin up options. This

card is installed at the rear of the enclosure in the lowest slot below the two Disk

I/O cards.

The SES processors continuously monitor the enclosure for temperature status,

fan status, power supply status, and FC loop status. The processors are

responsible for reporting environmental and system status to the front bezel

LEDs/audible alarms, SES Monitoring software (VT-100), and external monitoring

software such as StorView.

SES Controller Card

At power up, the SES processors will read the switch settings and execute a

self-test. The cards’ firmware also contains software functions for enclosure

monitoring and management. This firmware is flash upgradeable using the SES

RS-232 Service port located on the card face plate. Refer to “Uploading SES

Controller Card Firmware” on page 119 for more details.

The SES protocol uses the drives installed in slots 1 and 7 to maintain its

communication link. You must install drives in both of these slots to ensure fault

tolerance for the SES communications link.

Disk I/O Card

The Disk I/O card is provided for drive channel expansion. By connecting daisy

chained IRF-JBOD enclosures to the Disk I/O cards additional enclosures and

drives can be added to your system. This card’s design incorporates an active

hub, and provides automatic loop regeneration (LRC) and port bypass. The loop

regeneration function will “heal” the FC-AL (Fibre Channel-Arbitrated Loop)

when components become disconnected or faulty.

There are two Disk I/O cards installed at the rear of the enclosure adjacent to the

cooling fan bay. The upper Disk I/O card provides the connection to the “Loop

0” side of the disk drives, and the lower Disk I/O card provides the connection to

the “Loop 1” side of the disk drives.

Each Disk I/O card supports Small Form-Factor Pluggable (SFP) cages to accept

either optical or copper transceivers. They are designed to support NCITS T11

Fibre Channel compliant devices at speeds of 1.0625 Gb per sec or 2.125 Gb per

second. The speed is set through a hardware jumper (JP4) located on the Disk

I/O card. Set the jumper on one pin only or offset for 2Gb mode. If you need to

configure the system for 1Gb mode, position the jumper to both pins. An LED on

the card’s faceplate will illuminate to indicate the 2 Gb mode.

NOTE: The Disk I/O cards are universal and can be interchanged.

Host I/O Card

The Host I/O card provides the fibre connectivity from the host computer(s) to
the Fibre Channel controller ports. This hot swappable card is designed to
support NCITS T11 Fibre Channel compliant devices at speeds of 1.0625 Gb per
sec or 2.125 Gb per sec. Each card has two SFP cages that house optical or
copper SFP transceivers. They are labeled “H0” and “H1.”

The Host I/O cards are installed at the rear of the enclosure, above the controller
slots. The right Host I/O card provides connectivity to controller’s port 0 (C0P0 and
C1P0) of both controllers, and the left card provides connectivity to controller’s
port 1 (C0P1 and C1P1) of both controllers.

LEDs on the card’s face plate will illuminate to indicate 2 Gb speed mode, host
link status, and activity.

RAID Controllers

The imageRAID Series Storage System is designed to house one or two hot
pluggable imageRAID Controllers. They are next generation dual port
high-performance 2 Gb/second Fibre Channel-to-Fibre Channel RAID controllers
supporting RAID levels 0, 1, 5, 10, and 50.

There are two models of the
a FC-FC RAID Controller with a single RISC processor. The

imageRAID

Controller. The base

imageRAID

imageRAID

XP model is

model is

the base controller plus a co-processor.

The controllers are

designed for “I/O Intensive” and “Bandwidth Intensive”
applications, providing simplex (stand-alone) and duplex (active-active)
configurations designed for existing and future Fibre Channel topologies.
simplex operations, the controller operates autonomously. In

duplex

In

configurations, the two controllers operate as a pair. In the event one controller
fails, fault tolerance is maintained via hardware failover allowing either controller to
take over the operations of the other controller.

Fibre Channel-Fibre Channel imageRAID Controller

Each controller has two Fibre Channel ports and two Fibre Channel disk ports for

a “2x2” configuration (dual host-dual drive). In duplex configurations, it can

process up to 80,000 I/O’s per second (IOPS). The active-active pair of RAID

controllers can feed data to SAN nodes at a sustained rate of 320 MB/sec, and

process RAID 5 write operations at 220 MB/sec.

RAID Controllers

Chapter 1 - Getting Started

The core processor of the controller is based on an Intel XScale™ RISC processor

running at 600 MHz. The processor has integrated instructions and data caches

that allow for the most frequent instructions to be executed without having to

access external memory. Coupled with the micro kernel, it processes commands

and I/O’s at extremely high rates.

The processor’s companion chip implements dual independent 64-bit 66MHz PCI

busses. Devices on these busses have independent access to the shared 512 MB

of SDRAM. Also, an integrated XOR accelerator is included for RAID 5 or 50

parity generation.

The imageRAID Controller disk drive interface uses QLogic ISP 2312 dual Fibre

Channel controllers which takes full advantage of the dual fibre loops on each

disk drive. The controller’s host interface also uses QLogic ISP 2312 dual Fibre

Channel controllers which provides two independent ports for host connectivity.

Each port can operate at either 1 Gb/sec or 2 Gb/sec, and the controller will

automatically detect the correct rate. The ports are sometimes referred to as “Host

Loops.”

Located on the controller face plate are Activity, Link and Status LEDs. Refer to

the table below and the illustration on the following page for descriptions for

each LED.

NOTE: The “TXRX-LNK” and “1K-10/100” LEDs are provisions for future options.

Battery Backup Unit

The main board of the imageRAID Controller includes battery control circuitry for

a single cell Lithium Ion battery along with a battery pack mating connector. The

main purpose of battery backup is to maintain the cache memory during brief

power interruptions, but is capable of maintaining the memory content for

several hours, depending on the type and size of the memory.

Battery Backup Unit

Chapter 1 - Getting Started

The battery control circuitry has constant current, constant voltage (CCCV) charger.

The battery charger provides a maximum 250mA charge current. When the charge

current falls below 16mA, the charger determines that the end of charge has been

reached, generates an end of charge indication and shuts itself off. If the battery

voltage drops below 3.0V, a complete battery discharge is indicated.

The battery control circuitry includes a battery safety circuit. The safety circuit

protects the battery by limiting the over-voltage to 4.3V, the maximum discharge

current to 3A for catastrophic events, and the minimum battery voltage to 2.35V. If

any of these conditions exist, the safety circuit disconnects the battery. These

conditions will only exist if there is a hardware fault present, and would never be

seen under normal operating conditions. In addition, the battery pack utilized, part

number 44-9-95611001, includes a resettable polyfuse that trips when the current

exceeds 700mA at room temperature. This protects the 1 amp rated connector

when for example a partial short exists caused by aa component failure.

Lithium Ion batteries have no requirement for conditioning, even after partial

discharges. The current battery pack utilizes a Renata ICP883448A-SC cell, with a

nominal capacity of 1150mAh. For a completely discharged battery, the charge time

is approximately 5 hours. Under lab conditions, current draw was measured for

different configurations of memory. The table below shows the results of those

tests, and the expected backup time is indicated for the specified memory

configuration. The table shows the absolute maximum backup time calculated from

the current draw measurements. The “Expected Safe Backup Time” is the absolute

maximum de-rated by 50% to account for different operating temperatures and

capacity reduction due to battery charge/discharge cycles. This is the time that

should be used when developing a system level power backup plan.

Control and Monitoring

An integral part of the imageRAID Series Storage System is its control and monitor

capabilities.

The SES processors provide monitoring data for the enclosure environmental

conditions such as enclosure temperature, cooling fans, power supplies, and FC

Loop status. This data is reported to the monitoring system to provide LED and

audible alarm notifications. This monitored information is also communicated to

external monitoring software.

Refer to “VT-100 Interface Enclosure Monitoring” on page 116 for complete

details.

Chapter 2

Topologies and Operating Modes

This chapter provides an overview of the supported operating modes and
topologies. This information should provide you with an understanding to make
the best choices for the optimum configuration that compliments your storage
system solution.

Essentially there are two operating modes available: Simplex and Duplex. The
IRF-1Sxx-xx or IRF-1Dxx-xx models with their single RAID controller support the
simplex operating mode, and the IRF-2Sxx-xx or IRF-2Dxx-xx models with their
dual RAID controllers support the duplex operating mode.

Operating Mode Overview

These operating modes allow you to configure the enclosure’s drives and RAID

controller(s) to support a variety of host environments topologies.

■ Simplex – In this operating mode, the enclosure is configured as a RAID

storage system with its single RAID controller operating in a stand-alone

configuration. This operating mode supports dual port topologies.

■ Duplex – In this operating mode, the enclosure is configured as a RAID

storage system with dual RAID controllers operating in an active-active or

redundant fault-tolerant configuration. This operating mode supports

Multiple Port Mirrored topologies.

21

Chapter 2 - Topologies and Operating Modes

Simplex Mode

The simplex operating mode uses a single RAID controller solution that provides

a limited level of redundancy. With its dual port topology, the controller also

provides dual active ports that increases the bandwidth capabilities. Essentially,

there are four supported topologies for this operating mode:

■ “Dual Port Single Host Connection” on page 22

■ “Dual Port Single Host Dual Connection” on page 23

■ “Dual Port Multi-Host Single Connection” on page 24

■ “Dual Port Multi-Host Dual Connection” on page 25

Dual Port Single Host Connection

This topology provides an entry-level RAID storage solution for single ported HBA

host system. It offers the following advantages:

deploy

multiple points of failure (host server, host HBA, controller, and data cable), and it

has limited bandwidth capabilities due to its single Fibre loop (200 MB/sec).

Dual Port Single Host Dual Connection

This topology provides an entry-level RAID storage solution for dual ported host

systems with multiple paths to the storage. It offers the following advantages: an

initially lower cost system to deploy, multiple paths from host which can

maximize controller bandwidth, and it provides multiple paths for optional

upstream failover. It has several disadvantages: the RAID Controller is a single

point of failure, it requires two single ported HBAs or a dual ported HBA, and if

upstream path failover is implemented then additional software is required.

systems. It offers the following advantage: clustered storage between multiple

host system (no requirement for external hubs or switches). It has a few

disadvantages: the controller and the single fibre loop are single points of failure,

for clustering operations third-party clustering software is required and it also has

limited bandwidth performance due to a singe Fibre loop (200 MB/sec).

Chapter 2 - Topologies and Operating Modes

Duplex Mode

The duplex operating mode is a dual RAID controller solution providing a

redundant controller or an active-active RAID storage solution. Beginning with a

minimum level redundancy solution it can be configured to provide the most

robust redundant RAID storage solution. This operating mode supports the

Multiple Port Mirrored topology.

In a Multi-Port topology, all ports are active and provide transparent hardware

failover and failback operations. It provides for higher host bandwidth

capabilities with each port connected to an individual fibre loop.

During controller failure, internal HUB circuitry on the Host I/O cards

automatically detect a failure and connects the incoming Fibre loops together so

that the surviving controller immediately starts processing host commands.

There are essentially five supported topologies available for the Duplex mode:

■ “Multi-Port Mirrored Single Host-Single Connection” on page 27.

26

■ “Multi-Port Mirrored Single Host-Dual Connection” on page 28.

■ “Multi-Port Mirrored Dual Host System-Quad Connection” on page 31.

■ “Multi-Port Mirrored SAN Attach Single Switch Connection” on page 32.

■ “Multi-Port Mirrored SAN Attach Dual Switch Connection” on page 33.

NOTE: Some Operating Systems, such as HP-UX, when connected to a fabric

require that you set the Controller Parameter option “Host Different

Node Name” to enabled. This will cause the controller to present a

different Configuration WWN for each controller port. Otherwise if the

same WWN is reported on both ports, one port would be blocked by the

OS. Refer to the VT-100 or StorView Software Guide for specific

information on this option.

Multi-Port Mirrored Single Host-Single Connection

This topology provides an redundant RAID storage solution for single host systems

with one fibre port where a fault-tolerant disk subsystem storage is required. It has

the following advantages: initial lower costs, redundant RAID controllers, and

transparent failover and failback operations. It has several disadvantages:

performance limited bandwidth capabilities due to the single Fibre loop, and the

host system, host HBA and the single fibre loop are single points of failure.

LUN Mapping

The RAID Controller has extensive support for LUN Mapping or SAN LUN

Mapping (SLAM). A LUN can be mapped to particular host HBA or to a particular

host HBA port. Up to 512 LUN mappings can be created, with a 2 TB per LUN

limitation. Online LUN addition and deletion is supported.

LUN Mapping allows multiple hosts and operating systems with exclusive access

to certain areas of the storage, without requiring host software for management.

Additionally, an internal LUN can be presented to a host system as a different

LUN number, simplifying multiple systems setup.

Alternate Path Software

This is a software tool that manages multiple paths between the host operating

system and LUNs. The software manages the multiple paths by detecting

duplicate disk objects that represent a single LUN. It then designates one disk

object as the primary disk object with a primary path, while the other is

designated the secondary disk object with an alternate path. If the primary path

becomes inaccessible, the software redirects the data to the secondary disk object

through the alternate path, preserving the LUN.

This redirection is known as path failover. The software continuously tries to

access the failed path by issuing a SCSI Test Unit Ready command. A good status

returned indicates the path is repaired and restored to operational status. The

software automatically redirects data back to the primary path and primary disk

object. This restoration of data transfer is known as path failback.

Fibre Channel Media Types

Optical transceivers are provided with the enclosure. Fibre optical transceivers

provides a more reliable media and supports distances up to 300 meters between

nodes.

A Word about Clustering

Minimizing Downtime for Maximum Data Availability

So-called open systems, such as Windows servers, just don’t provide the level of

availability that IS managers are familiar with on mainframes. A partial solution to

this problem is server clustering.

Clusters consist of two or more loosely coupled systems with a shared-disk

subsystem and software that handles failover in the case of a node (host) failure.

In most cases, hardware/software failover is performed automatically and is

transparent to users, although users will experience performance degradation as

processing is shifted to another cluster node. In some cases this failover can

occur in a matter of seconds.

High availability of data and applications is by far the most compelling reason to

go with clustering technology. For example, the accepted rule is that stand-alone

UNIX systems can provide 99.5% uptime. Adding a RAID subsystem can increase

the uptime to 99.9%. The goal of clustering is 99.99% availability.

Beyond clustering, fault-tolerant systems can provide 99.9999% uptime. At the

high end, continuous-processing systems offer virtually 100% uptime.

Although the increase from 99.5% to 99.99% availability may seem insignificantly

small, it adds up in terms of minutes per year of downtime. For example,

assuming a 7x24 operation, 99.5% uptime translates into 2,628 minutes — or

more than 43 hours of downtime per year. In contrast, 99.99% uptime translates

into less than one hour (52 minutes) of downtime per year.

Availability figures relate primarily to unplanned downtime. But the advantages

of clusters in terms of planned or scheduled downtime are even more significant.

If you figure two to sixteen hours per month for a server in a large shop.

Planned downtime requires shutting down stand-alone systems entirely. Result:

100% loss of processing for the duration of the downtime. But, with cluster, you

can shut down one node and off-load the processing to other nodes in the cluster

with no interruption of processing.

A Word about Clustering

37

Chapter 2 - Topologies and Operating Modes

High availability is not the only benefit of clustering. In some cases, users may

see advantages in the areas of performance, scalability, and manageability. In

reality, you can expect a 1.6x (80% efficiency) to 1.8x (90% efficiency)

performance increase as you go from one node to two nodes. Going from one

node to a four node cluster generally yields a 2.5x or 3x performance boost.

However, the cluster performance is application dependent. For example, READ

operations may yield a 1.8x performance increase going from one to two nodes,

but in a WRITE intensive application, you may only see a 1.4-1.6x improvement.

Although clusters seem to be relatively simple, they involve complex technology

that can be implemented in a variety of ways. The number of nodes supported

and type of interconnection used, and a number of other features differentiate

cluster implementations. One area of implementation is the manner in which

distributed lock manager is implemented. Some perform this at the user level and

others in the kernel, with the latter enhancing performance.

In addition to the differences of features you should consider the following:

Does the cluster:

• have the ability to hot load new nodes without bringing down the
whole cluster?

• provide automatic or manual failover?

• load balance?

• use a journalized file system?

• provide a fast cluster failover?

• allow for the nodes to be geographically located?

Setup and Installation

Overview

This chapter describes the procedures to install and setup the imageRAID Series

Storage System. Each section will step you through the hardware installation,

cabling and topology configurations.

It is important to thoroughly review this information and perform the steps of

procedures in each applicable section in the order in which they are presented.

This will ensure a smooth and trouble-free installation.

The installation is divided into two sections. The first section describes installing

the enclosure(s) into the rack cabinet or installing the enclosure chassis into the

tower stand. The second section describes the topology operating mode

configuration and cabling the enclosure(s).

You should review the “Topologies and Operating Modes” on page 21 to ensure

a complete understanding of the options available.

41

Chapter 3 - Setup and Installation

Storage System Detailed Installation

This section describes preparing and installing the enclosure(s) into the rack

cabinet or the enclosure into its tower stand “Installing the Storage System into

the Tower Stand” on page 45.

After installing the hardware components, go to the “Operating Mode

Configuration and Cabling” section, and set the

described and cable the enclosure(s) for your selected topology.

Installing the Storage System Enclosure into the Rack Cabinet

1 Install the storage enclosure(s) into the rack cabinet.

Select an appropriate location within your rack cabinet. You should consider
the location of the enclosure(s) in relationship to each other to ensure that the
cables will easily reach between enclosures when installing multiple
enclosures.

CAUTION:

2 Remove each enclosure from its shipping carton and inspect for obvious

damage. Place the enclosure on a flat surface to work from.

3 Remove the front bezel from the accessory box and store it in a location

where it will not be damaged. It will be installed later in the installation
procedures.

4 Remove the power supplies.

From the rear of the enclosure, remove a power supply by grasping its
handle and pressing in on the release latch with your thumb as you pull the
power supply from the enclosure. Repeat for the other power supply.

5 Locate the mounting hardware in the accessory kit (mounting rails, screws,

and nuts – on some rack installations you will use cage nuts and on some

racks they will be standard nuts).

NOTE:

6 Lift and secure the enclosure into the rack cabinet.

The power supplies should be removed prior to installing the
enclosure. The enclosure chassis could be damaged during
installation due to the added weight of the power supplies.

It will be helpful to have an assistant available during the installation.

and diagrams for setting the SES Controller card switches, Host I/O card switches

and attaching the required Fibre Channel data cables for configuration. Locate the

applicable operating mode topology and follow the steps and diagrams provided.

In the last section of this chapter are the steps to properly power on or power off

your storage system.

Special Note for Microsoft Windows 2000 Installations

At startup you will see the “Found New Hardware Wizard” appear. Although a

driver is not required for the storage system, a driver .inf file is provided on the

Software/Documentation Disc which can be installed to satisfy this requirement.

Refer to the ReadMe file located in the Drivers directory on the Software/

Documentation Disc for instructions, then follow the on screen wizard to

complete the driver installation.

Chapter 3 - Setup and Installation

Operating Mode Configuration and Cabling

In this section you will find the instructions for setting the SES Controller card

switches and Host I/O card switches, followed by illustrated instructions to setup

and cabling the specific operating mode topology.

SES Controller Card Switch Setting Overview

A word about Fibre Channel device IDs. Under the FC protocol, device IDs can

be generated in several ways: hard addressing, previous addressing, and

negotiated addressing. RAID controllers prefer hard device addressing which

ensures that the device ID will always be the same. It is set using a specific set of

switch settings. Previous addressing is a method that allows the system to

determine whether or not the device has had a previous address ID assigned to it

and will attempt to use that ID, if it is not available it will assign a new ID. And

negotiated addressing occurs when a hard address or a previous address do not

exist and it will then negotiate the bus for a new device ID. The disadvantage of

negotiated device IDs is that there is a potential liability of the device ID

changing due to reconfiguration and therefore could cause potential problems for

the RAID controller’s array drive members.

The SES Controller card has a set of switches which configures the enclosure

base address and assigns a device ID to the drive slots, and sets the drive spin-up

options. The disk drive slot IDs are determined by the first three switches,

labeled AD0, AD1, and AD2. They establish a base enclosure hard address and

assign the drive slots each with a pre-determined set of IDs.

Switches 4, 5 and 6 are spares, and switches 7 and 8 set the drive spin-up

options.

The table on the following page displays the available device ID ranges for each

series of switch settings. Following the diagram, is an illustration which depicts

the drive slot layout within the enclosure.

Drive Slots and Sample IDs Assigned

NOTE: Odd numbered drive slots are assigned to Channel 0 and even numbered

drive slots are assigned to Channel 1 of the RAID Controller. This allows
for improved performance throughput.

1 Locate the switches on the SES Controller card and set them as described for

the specific range needed.

2 If you have daisy-chain expansion enclosures, set their SES Controller card

switches to the next available range of IDs, as desired.

For example, if you have two enclosures installed, the first is a imageRAID

IRF-1Dxx-xx with a single RAID Controller (master) and the second

daisy-chain enclosure is a IRF-JBOD system (slave). Set the master RAID

enclosure to IDs 0 - 11, and the daisy-chain slave enclosure to IDs 16 - 27.

3 (If necessary) Set the spin-up options for the disk drives. Normally the

default settings are sufficient and configure the spin-up options to spin the

drives up upon a power on condition. However, you may require a specific

or different configurations for the drive spin-up option. Refer to the table

below for the appropriate settings for spin-up options.

* Default setting for proper operation.

This concludes the overview of setting the SES Controller card switches. Locate

your selected operating mode and complete the setup. You will be instructed at

the appropriate time to set the switches as described previously.

Chapter 3 - Setup and Installation

Simplex Mode (imageRAID IRF-1Sxx-xx/IRF-1Dxx-xx)

The basic simplex (Stand-Alone) operating mode provides a single enclosure
with a single RAID Controller solution. This mode provides solutions for single or
multiple host environments to achieve a fault-tolerant disk storage solution. It has
provisions for drive channel expansion through daisy-chaining of IRF-JBOD
enclosures, and/or upgrading to a imageRAID IRF-2Dxx-xx model by adding an
additional controller for duplex operations.

CAUTION: The bus speed must be set to the same setting between the disk

drives and the Disk I/O card(s), and the host system HBAs (BIOS
setting) and the Host I/O cards. For example, if you are using 2 Gb
drives, the Disk I/O cards must be set to 2 Gb mode. If your host
system HBA(s) is set to 1 Gb mode, the Host I/O card(s) must be set
to 1 Gb mode.

NOTE: Split-bus mode is not supported when a RAID Controller is installed.

Stand-Alone Dual Port Single Host Configuration

1 Set the jumper (JP4) on the Disk I/O card to configure the bus speed mode.

Loosen the two captive fastener screws on the Disk I/O card and pull it from

the enclosure using the fastener screws. Locate the jumper JP4 and position it

for the desired speed setting, (installed on one pin only for 2 Gb mode and

on both pins for 1 Gb mode).

Jumper JP3 must be offset
or installed on one pin only.
This enables Single Bus mode.

Stand-Alone Dual Port Dual Host Dual Connection Configuration

Chapter 3 - Setup and Installation

Duplex Mode (imageRAID IRF-2Sxx-xx/IRF-2Dxx-xx)

The basic duplex operating mode provides a single enclosure with dual RAID

Controllers. The two controllers operate in an active-active configuration, where

both controllers are actively processing data. This greatly improves the overall

system performance and provides the most robust system redundancy.

The supported operating mode is Multi-Port Mirrored, where all controller ports

are active and connected to individual fibre loops. It provides transparent

hardware failover and failback. During a controller failure, internal HUB circuitry

located on the Host I/O cards automatically connects the incoming Fibre loops

together and the surviving controller immediately starts processing host

commands.

This duplex mode supports several cabling configurations.

The configurations

demonstrate attachments to a single enclosure and multiple enclosures.

CAUTION: The bus speed must be set to the same setting between the disk

drives and the Disk I/O card(s), and the host system HBAs (BIOS
setting) and the Host I/O cards. For example, if you are using 2 Gb
drives, the Disk I/O cards must be set to 2 Gb mode. If your host
system HBA(s) is set to 1 Gb mode, the Host I/O card(s) must be set
to 1 Gb mode.

NOTE: Split-bus mode is not supported when a RAID Controller is installed.

Multi-Port Mirrored Single Host-Single Connection Configuration

1 Set the jumper (JP4) on the Disk I/O card to configure the bus speed mode.

Loosen the two captive fastener screws for the Disk I/O card and pull it from

the enclosure using the fastener screws. Locate the jumper JP4 and position it

on both pins for 1 Gb mode).
