1.6 Software and Firmware Updates
RAID. Inc. will provide RAIDWatch and controller firmware
updates periodically via our distributors and sales offices.
1.7 Installation Overview
This manual can be used to install any of the following ER2510FS
RAID Controller Head models:
•
ER2510FS-4S
•
ER2510FS-6S
•
ER2510FS-4RH
•
ER2510FS-6RH
The variations between these models are described below.
1.8 Model Variations
The ER2510FS RAID Controller Head, described in this manual
comes in four different models (see above). Variations between
these models give users extreme configuration flexibility and enable
them to configure storage management subsystems that are uniquely
suited to their needs. The differences between the four models are
described below.
1.8.1 Four Models
The four models can be separated into two controller categories,
single-controller models and dual redundant controller models.

Dual-Redundant
Table1-1: - ER2510FS Models
Single Controller Models: - These models should be used when
there is a low demand on data availability and a fully redundant
system is not a critical requirement for the system.
Dual Redundant Models: - Dual-active configurations may require
dual loops to create full path redundancy. There are no single points
of failure in a dual-active configuration and they should therefore be
used when data accessibility is a critical requirement of the storage
network that is being implemented.
1.8.2 Fibre Channels
Different models come with varying number of fibre channels and
single IO module type. These IO modules are referred to as Type-1
IO Modules and they are fully described in Chapter 2.
The ER2510FS-4S, and ER2510FS-4RH only come with four
available fibre channels. The system is designed to accommodate 6
IO Channel Modules (see Chapter 2). Dummy canisters are
provided in the place of the additional IO modules.
WARNING
The dummy canisters that come with the four channel controller
models must be installed into the system. They are provided so
that the airflow from the fans can be normalized. If the airflow is
1-6
Introduction
not normalized the system will overheat, be permanently
damaged and void our warranty.

Models
RCC Channels: - Both the redundant Controller Models come with
preset channels for Redundant Controller Communication (RCC)
connection. In the ER2510FS-6RH if CH4 or CH5 have no external
FC cables connected to them, they can be used as dedicated RCC
Channels. If cables are connected to these channels then they can be
used as drive + RCC channels.
CH2 and CH3 on the ER2510FS-4RH are both drive + RCC
channels.
1.8.3 Active Component Variations
The single controller models, the ER2510FS-4S and ER2510FS-6S,
only come with:
Introduction
1-7
•
A single maintenance module
•
A single battery backup unit (BBU)
The redundant models have two each of the above components.
Instead of receiving these active components, users will receive
dummy canisters in their place. It is imperative that these canisters
be installed. They regulate the airflow within the enclosure.
WARNING
The dummy canisters that come with the single controller models
must all be installed into the system. They are provided so that
the airflow from the fans can be normalized. If the airflow is not
normalized the system will overheat and be permanently
damaged.

Hardware Overview
installed. Each cooling FAN module is assigned to cool a single
controller module.
The cooling FAN module consists of two individual FANs, if one of
these fans should fail the second individual fan can keep the
controller module sufficiently cooled. Both cooling FAN modules
have simple hot-swappable mechanisms, which are independent of
each other and the controller modules and makes changing FAN
modules fast and easy.
CAUTION
Although an individual FAN in the cooling FAN module can
sufficiently cool a controller module it is not recommended. If you
are using a single FAN and it should fail then the system can
overheat. Failed FANs should be replaced as soon as possible.
Delays in FAN replacements can lead to irreparable system
damage.

Please note that the installation instructions described in this
manual should be carefully followed. If they are not carefully
followed, your system may be damaged.
3.2 Installation Pre-requisites
3.2.1 Static Free Installation
Static electricity can damage the electronic components of the
system. Most of the controllers that are returned for repair are the
results of improper installation and electrostatic discharge (ESD)
damage. To prevent ESD damage to any of the PCBs, before
touching or handling them follow these precautions:
•
Discharge the static electricity from your body by touching a
grounded metal surface.
Hardware Installation
3-1
•
Use an anti-static wristband to ensure that all the static has been
discharged from your body.
•
Do not use carpets, plastic, vinyl or Styrofoam in your work
area.
•
Make sure all the PCBs are at room temperature before
removing them.
WARNING
Most controllers that are damaged and returned for repair have
been damaged by ESD. When working with the controller boards,
or any other circuit boards, ensure that you are working in a
static free environment to minimize the chance of ESD damage.
3.2.2 ER2510FS Cabinet Requirements
The ER2510FS RAID Controller Head can be fitted into a standard
cabinet or rackmount rack. It is assumed that this cabinet/rack would
be well ventilated and designed to allow the fibre channel cables to
be easily connected to both the drives and host. The ER2510FS
controller head can be fitted into the cabinet by means of an easy to
install slide-rail and secured to the cabinet/rack with screws. A full
discussion of this will follow later.
3.2.3 ER2510FS Cable Requirements
To connect the various hardware components to the appropriate
external devices (JBOD enclosures, hubs, switches, HBAs, etc)
specific cables are needed. These cables must not be bent or
manhandled as they could be damaged. When installing the cables
into the system take precautions that they are not damaged or cause
damage in anyway. Please refer to Chapter 5 for more details.
3-2
3.2.4 Host Requirements
In order for the ER2510FS RAID Controller Head to be connected

3.7 Memory Installation
NOTE:
The controllers that are installed in the controller module are
able to support a cache size between 64MB and 1GB on one
SDRAM DIMM with or without ECC support. The controllers
ONLY support 133MHz SDRAM.
The ER2510FS RAID Controller head comes with one or two RAID
Controller Modules (depending on the model). Each controller
module contains a RAID Controller Board. The SDRAM DIMMs
are not installed on the controllers. The SDRAM modules must be
purchased and installed separately. For a dual redundant controller
configuration the modules should be equal in size and performance.
Install these chips with care.
WARNING
1. When you install the cache memory chips it is necessary to
remove the controller board from the controller module. Do
this with care and consideration in order not to cause
permanent damage to the board. This is the only time the
controller board should be touched by the user.
2.
Please purchase the correct memory modules from your
ER2510FS Controller Head vendor/distributor.
Steps
1.
DIMMs must be installed before the RAID Controller Module
is installed. Note, if you are installing controllers in a redundant
configuration the DIMMs must BE THE SAME SIZE.
CAUTION
If you are installing the RAID Controllers in a Dual Redundant
configuration, the memory capacity of the DIMMs should be
identical

Insert Lower Screw
Figure 3-10: - Secure the front panel modules into the chassis using
two screws.
6.
Repeat this process until all the front panel modules (including
the dummy canisters) have been installed into their correct
locations.
WARNING
The dummy canisters must be installed. If these canisters are not
installed then the cooling airflow will not be normalized and the
system will be damaged.

3.12 Mounting the ER2510FS into the Rack
The ER2510FS RAID Controller Head can be installed into a
cabinet using different techniques and in different orientations. This
section will describe how to mount the controller head into a cabinet
using a separately purchased slide rail.
CAUTION
1. When installing the RAID Controller head into the cabinet it
is best to have two people assisting in the installation process.
One person will need to hold the controller head while the
second person will need to make the necessary attachments.
3.12.1 Pre-Installation Considerations
Selecting the orientation: - The ER2510FS RAID Controller Head
comes with two front ears that are used to secure it to the cabinet.
These ears are reversible and can be placed at the rear of the
Controller Head enabling users to select the orientation of the
Controller Head. If you choose to install the chassis backwards it is
necessary to remove the handles from the front of the chassis (see
figure 3-11)
Figure 3-11 : Removing and replacing the handles at the front.
3-18
and replace them at the back (see figure 3-12).
Figure 3-11: Removing and replacing the handles at the back
Handles: - Make sure the front/rear handles are firmly attached to
the chassis of the controller head with two screws.
Location Selection: - Carefully select the location in the Cabinet of
where you want to place the Controller Head. Pay attention to the
clearance between rackmount units.
3.12.2 Slide Rail Installation
NOTE
Using a slide rail is an optional installation technique. The IFT9253L18 slide rail can be purchased separately and used to install
the ER2510FS controller head into a cabinet.
The slide rail kit includes the following components:
•
2 Slide Rails
•
18 M4x0.7 L=6 Phillips screws plus Kepnuts (8)
•
4 End Brackets
The slide rail assembly consists of four major parts: the inner slide
rail (for the chassis), the middle slide rail (ball-bearing part), the
outer slide rail (for the cabinet), and two end brackets.
3-19
Installation Steps
1.
Separate the inner chassis slide rail from both rails. To do this
press the spring catch in each to release the inner section of the
rail. Place the inner chassis slide rail in the correct orientation.
To do this note that one end is level and one end has a
protruding edge. The end with the protruding edge must be
towards the back of the unit. (The open side of the inner rail
section must face out as shown.) Attach the inner chassis slide
rails to the sides of the ER2510FS RAID Controller Head using
the enclosed screws.
Figure 3-12: - mounting hole locations
2.
3-20
Determine where in the network equipment cabinet the
ER2510FS management system will be installed. Pay attention
to the clearance between rackmount units. Mount the end
brackets on both the left and right (two on each side). Attach
the end brackets to the mounting holes of cabinet. The
mounting positions for the end brackets within the cabinet
must be carefully measured so that the rails can be mounted
parallel. Attach the end brackets to each side of the cabinet
using screws provided with your cabinet.
End Bracket
Figure 3-13:- End Bracket
3.
Attach the middle and outer slide rails to end brackets. Make
sure the rail heights are aligned. Orient the slide rails so that the
metal stop is toward the back of the cabinet so the middle slide
can extend out the front of the cabinet.
Push the middle slide until the mounting holes of the outer slide
rail are revealed. Insert screws from the inside and put a kepnut
on the end of each screw. Align the round holes on the middle
slide until screws can come through slot on the end bracket.
Fasten the screws between end brackets and the outer slide rails.
To see the mounting holes slide the rail forward
Metal Stop
Figure 3-13: Attach the middle and outer slide rails to the end
brackets
3-21
Pull the ball bearing part of slide rail forward and backward and
secure screws through the two slots on end brackets. Adjust
each slide rail before tightening it to the end brackets.
4.
Before installing the subsystem, you may have to pull both slide
rails out until you hear a “click” sound made by the metal stop.
Gently slide the subsystem into the rack by aligning the inner
sections of the rails (now mounted to the subsystem) with the
rail sections mounted to the equipment cabinet.
When the unit is inserted approximately half-way, you will need
to press the spring catches on both sides as shown in order to
continue mounting. Two persons are needed to carry the
system. Slide the subsystem as far in as it will go, then secure
the system with four screws on the sides of front panel.
Press to Slide Back

Monitoring the
System
4.1 Overview
This chapter instructs user on how to monitor their ER2510FS
RAID Controller Head. LEDs, Audible Alarms, Firmware and
Software can all be used to monitor the status of the ER2510FS
Controller Head. The ER2510FS also supports SCSI Enclosure
Services (SES) monitoring or the drive enclosure.
4.2 System Monitoring
The system can be monitored in five different ways:•
Firmware: - using the front panel LCD screen or the PC HyperTerminal program.
•
LEDs: - the front panel modules all have LEDs on the front.
These LEDs are used to inform the end user about different
system information.
•
Software:- using a GUI called RAIDWatch.
•
Audible Alarm: - an audible alarm will be triggered when
certain system thresholds are violated. The alarm is used to
notify, alert or warn a user about different events. Examples of
Monitoring The System

these events are temperature and voltage. For more details refer
to section 4.6.
•
SES Monitoring: - the RAID Controller Head supports SES
monitoring of the drive enclosure. For more details refer to
section 4.7.
NOTE:
The controller head devices are not monitored via SES. Only the
drive enclosures are monitored with SES.
4.3 Firmware
The firmware is pre-installed on the controller boards. It is used to
configure and access system information. Both the front panel LCD
screen and a PC terminal can access it. Using the Firmware to
configure and monitor the system has been fully described in the
“Generic Operation Manual” that came with your system. Please
refer to this manual for further information.
4.4 Front Panel LEDs
4.4.1 IO Modules
Type-1 IO modules have two green LEDs on the front side of the

4.5 RAIDWatch Manager
The RAIDWatch Manager enables users to manage and maintain the
RAID Controllers using their web browsers. The following briefly
describes the installation steps for the RAIDWatch Manager. More
detailed information on the installation process and how to use the
RAIDWatch manager can be found in the Generic Operation
4-7
Manual, that came with the system, and in the RAIDWatch User’s
Manual.
NOTE:
The RAIDWatch User Manual can be found on the CD that came
with the system. To access the RAIDWatch User’s Manual please
refer to this file.
4.5.1 Notification Processing Center (NPC)
The NPC is a powerful module that runs as a background Disk and
Executive Monitor (DAEMON) independent from RAIDWatch that
can, itself, be installed redundantly on different hosts. It is used for
event notification over Email, fax, LAN broadcast, SNMP traps, etc.
It helps to prevent blind time and keeps a user constantly informed
as to the status of the storage management subsystem.
4.5.2 Requirements
The requirements for a computer running web-based RAIDWatch
are the same as those for the clients described in the RAIDWatch
User Manual. Java plug-in us also necessary for a management
station.
4.5.3 Ethernet Ports
The ER2510FS RAID Controller Heads all come with an ethernet
LAN port for each controller. These LAN ports can be found on the
maintenance modules on the front panel (slot 7 and slot 8).
4.5.4 Installation Steps
1.
4-8
Install the RAIDWatch onto the host computer. Follow the
installation instructions that are given in the RAIDWatch User
Manual.
2.
Use the Firmware to create a logical array (see the Generic
Operation Manual). Make sure that you reserve a space of at
least 256MB. This reserved space is required for the
RAIDWatch Files that will be transferred to the RAID
Controller.
CAUTION:
If you do not reserve a space of at least 256MB, you will not
be able to transfer the necessary RAIDWatch files to the
controller and will therefore be unable to use the
RAIDWatch Program.
3.
Use the firmware to assign an IP address to the controller and
specify the NetMask and gateway values. To do this please
refer to the Generic Operation Manual.
4.
FTP the following RAIDWatch Programs to the designated
controller address.
•

4.6 Audible Alarm
Whenever any of the threshold values assigned to the different
controllers are violated or when an active device in the controller
head fails, an audible alarm will be triggered. To determined what
has triggered the alarm the user will have to read the error message
on the LCD screen or on the PC terminal.
WARNING:
If an alarm is triggered it is necessary for the user to determine
the problem. If the audible alarm is ignored or not taken seriously
and the problem is not rectified, permanent damage to the system
can result.

command set that is used to manage and sense the state of the power
supplies, cooling devices, temperature sensors, individual; drives,
and other non-SCSI elements installed in a fibre channel JBOD
enclosure. If you have a SES-compliant enclosure the firmware on
the controller boards will be able to decode and report this
information.
NOTE:
The SES monitoring support assists users in determining where a
fault may or may not exist within an external enclosure. If there is
a fault in the enclosure please contact the enclosure manufacturer
to solve the problem.

Configurations,
Cables and
Topologies
5.1 Overview
This chapter outlines some basic configuration rules that a user
should use when they are configuring a storage system. It also
introduces basic information about fibre channel cables and
introduces fibre-to-fibre topologies. Three sample topologies are
outlined. The user can set their system up using these topologies or
use them as a guide for developing their own unique topologies.
5.2 Basic Configuration Rules
When you are configuring your storage subsystem, the following are
some basic rules that should be followed.
NOTE:
Please adhere to these basic configuration rules. They are provided
for your convenience to ensure that your storage system will run
smoothly and effectively.
•
When selecting the number of hard drives that should be
connected through the drive channels, the transfer rates and the
mechanical performance of the hard disks should be considered.
Configurations and Topologies
5-1
•
When cabling, follow all the fibre channel specifications. Pay
attention to signal quality and avoid electronic noise from
adjacent interfaces.
•
The drives in the same logical array should have the same
capacity, but it is preferred that all the drives have the same
capacity.
•
A spare should have a minimum capacity that is equivalent to
the largest drive that it is expected to replace. If the capacity of
the spare is less than the capacity of the drive it is expected to
replace then the controller will not proceed with the failed drive
rebuild.
5.3 Fibre Channel Cables
NOTE:
Fibre Channel cables are expensive components that need to be
purchased separately. These cables are sensitive and should not
be bent as they are susceptible to damage.
5.3.1 Fibre Channel Speed Detection
Speed auto-detection is specified by the Fibre Channel standard. If a
1Gb/s port is connected to a 2Gb/s port, it will negotiate down and
run at 1Gb/s. If there are two 2Gb/s ports on either end of the link
the link will be run at 2Gb.
NOTE:
1. For the Type-1 IO modules, users have to manually select the
fibre channel speed of the IO module using a jumper. Please
refer to chapter 3 to see how this is done.
2.
5-2
If the fibre channel cable that is being used is too long your
system may end up running at 1Gb/s even with two 2Gb/s
ports.
5.3.2 Choosing the Fibre Cables
The Fibre Channel Standard allows for both copper and optical
connections. Copper cables are cheaper but limited to lengths of less
than 30m. Optical cables can be used over longer distances and have
been shown to be more reliable. Due to the extremely high data
transfer rates, optical cables are preferred for 2Gb/s fibre
connectivity. Optical cables are also less susceptible to EMI.
5.3.3 Lasers
WARNING:
Lasers can cause permanent eye damage, which may result in
permanent blindness, and therefore must be treated with respect
and used with caution. Never look at lasers without knowing
whether they are on or off is hazardous.
Wavelengths: - The lasers on fibre channel fiber optic cables emit
either short wave (SW) beams (770nm – 860nm) or long wave (LW)
(1270 nm - 1355 nm) beams. Cables that use either of these
wavelengths can be used on the ER2510FS controller head.
Laser Types: - Two type of laser devices can be used in fibre cables:
Optical Fibre Control (OFC) and non-OFC lasers. The OFC lasers
are high-powered and can be used over long distances.
Safety features: - OFC lasers, due to their high power output,
usually come with a safety mechanism that switches the laser off as
soon as it is unplugged. Non-OFC lasers do not (due to their low
power) come with these safety features but they can still inflict
damage.
5.3.4 SFP Transceivers
Once you have purchased your fibre channel cables, it may be
necessary to connect them to small form factor pluggable (SFP)
transceivers. These transceivers should typically have at least 2Gb/s
5-3
bi-directional data links, a laser transmitter (for fiber optic cables),
LC connector and a metal enclosure to lower the EMI.
NOTE:
LC connectors are small form factor, fiber-optic connectors based
on a 1.25-mm ceramic ferrule and the familiar latching
mechanism of the RJ-45 modular plug and jack.
Other beneficial features for a typical SFP transceiver include a
single power supply and low power dissipation. It is also preferable
that these transceivers are hot-swappable. It is also important that
any transceiver you use meets the Fibre Channel Performance and
reliability specifications.
NOTE
SFP Modules must be purchased separately. Please purchase the
correct SFP modules from your ER2510FS Controller Head
vendor/distributor.
5.4 Fibre Topologies
The ER2510F RAID Controller head uses up to two fibre controllers
for the RAID subsystem. The Fibre Channel Standard has been
designed to support three separate topologies. They are point-topoint, FC-AL and fabric switch topologies.
5-4
•
Point-to-Point: Point-to-point topology is the simplest
topology that can be used. It is a direct connection between two
fibre channel devices.
•
FC-AL: This is the most common topology currently in use.
Fibre channel devices are all connected in a loop. Each device is
assigned an arbitrated loop physical address (AL_PA). The FCAL is able to support 127 devices in a single loop.
•
Fabric: The fabric topology can support up to 224 fibre channel
devices. This topology allows many devices to communicate at
the same time. To implement this topology a fibre switch is
required.
5.4.1 Host Side Topologies
The Host Channels of the ER2510F RAID Controller head supports
all three topologies described above. The primary concern for
configuring host-side topologies is that points of failure are avoided.
It is therefore recommended that the host side be connected to at
least two HBAs. It is also preferable to connect the RAID subsystem
to the host computer(s) through either a fibre channel hub or a fibre
switch.
In the configuration examples given below, all the host channels are
connected to HBAs. It is also possible to connect the host channels
to fabric switches.
NOTE:
To create dual redundant data paths on the host side, it is
necessary for failover software to be installed on the host
computer.
5.4.2 Drive Side Topologies
The drive side channels support FC-AL topologies. It is
recommended that you use an FC-AL topology with your harddrives as this will allow you to use and manage more storage space.
The drive channels can be connected directly to a JBOD or through
a fibre hub to a JBOD. It is also recommended to connect two
channels to each JBOD. This will ensure full data path redundancy.
If one data path is disconnected, damaged or destroyed the second
data path will inherit the workload.

5.6 Redundant Controllers
Redundant Controller Pre-requisites
Before two controllers can be configured in a redundant controller
mode the following pre-requisites need to be met:
•
Both controllers must have exactly the same cache size.
5-9
•
Both controllers must be using an identical firmware version.
5.6.1 Redundant Controller Modes
Two different redundant controller modes are supported: the activeto-standby and the active-to-active mode.
•
Active-to-standby: If this redundant controller mode is
employed then one controller, the primary controller, does all
the work while the other controller, the secondary controller,
waits for the primary to fail. If, and when, the primary
controller fails the secondary controller will take over the
operation of the RAID subsystem.
•
Active-to-active: This redundant controller mode allows the
workload to be shared between the two controllers. This will
increase the operating speed of the system and allow the full
potential of both controllers to be exploited. If one controller
fails the second controller will take over the entire workload.
5.6.2 Internal Connections
The two controllers are connected to each other internally through
the Mid-Plane board. This enables the two controllers to
synchronize their caches and distribute the workload between the
controllers. The drive channels are also connected internally, via the
mid-plane board, to both controllers. This enables the correct
distribution of load traffic.
5.6.3 Unique Identifier
The Unique Identifier is a user specified 16 bit, hexadecimal number
that is used to assign a fibre channel port number to the primary
controller. Each controller is assigned a separate hexadecimal
number. The firmware then determines which Unique Identifier to
use. To see how to use the front panel LCD screen or the terminal
5-10
emulation program to enter the unique identifier, please refer the
Generic Operation Manual.
5.6.4 Redundant Controller Configurations
•
Channel Mode:- Every fibre channel can be configured as a
drive or host channel manually. There is no limit to the number
of drive or host channels that should be configured in the
system. Therefore in the ER2510FS-6 RAID Controller Head,
there maybe as many as five drive channels and one host
channel or as many as five host channels and one drive channel.
Channel 0 and 1 are, by default, host channels.
•
ID/LUN Mapping:- I/O load distribution is determined by the
Host ID/LUN mapping. Different logical groups of drives are
mapped to the LUN numbers under a host ID. For a multi-host
operation, a logical drive configuration can be mapped to
different ID/LUN combinations. In this case the File locking
mechanism is necessary. ID/LUN Mapping procedures are
described fully in the Generic Operations Manual.

System Features
A.1 Overview
The ER2510FS RAID Controller Head comes with many different
features. Some of these features enhance the performance of the
system, other features add configuration flexibility and other
features simplify the installation, maintenance and upgrade
procedures of the system. This section highlights some of the
features of the ER2510FS RAID Controller Head.
A.2 Flexible Configuration Options
A.2.1 Four Models
The ER2510FS RAID Controller Head comes in four different
models. This provides users with extreme configuration flexibility
and enables them to customize their systems to meet their unique
and specific needs. Differences between the models include different
controller configuration modes, the number of available fibre
channels and the IO module type. Table A-1 lists the four different
models and briefly summarizes their differences.

Table A-1: ER2510FS Model Variations
A.2.2 Front Panel Variations
To facilitate the use of two different IO Modules on the front panel
two different front panels have been developed.
A.2.3 Fibre Channel Configuration
All the ER2510FS RAID Controller Heads come with a minimum of
four and a maximum of twelve 2Gb/s fibre channels. All the
channels can be configured as either host or drive channels. The host
channels support point-to-point, fibre switch and fibre channel
arbitrated loop (FC-AL) connectivity, and are therefore able to
connect to the Host Bus Adapter (HBA) through either a Hub or a
Fabric Switch. The drive channels all support both point-to-point
and FC-AL connectivity.
A.3 RAID Support and RAID Levels
The ER2510FSRAID Controller Head comes with a minimum of
one and a maximum of two IFT5251F-4 or IFT5251F-6 RAID
Controllers. Both models are 2Gb/s fibre channel controllers and are
A-2
System Features
designed to provide RAID level 0, 1 (0+1), 3, 5, 10, 30, 50, or
JBOD RAID storage.
A.3.1 Non-RAID Storage
One common option for expanding disk storage capacity is simply
to install multiple disk drives into the system and then combine
them end to end. This method is called disk spanning.
In disk spanning, the total disk capacity is equivalent to the sum of
the capacities of all fibre drives in the combination. This
combination appears to the system as a single logical drive. Thus,
combining four 1GB fibre drives in this way, for example, would
create a single logical drive with a total disk capacity of 4GB.
Disk spanning is considered non-RAID due to the fact that it
provides neither redundancy nor improved performance. Disk
spanning is inexpensive, flexible, and easy to implement; however,
it does not improve the performance of the drives and any single
disk failure will result in total data loss.

A.3.2 JBOD
JBOD stands for Just a Bunch of Drives. The controller treats each
drive as a stand-alone disk, therefore each drive is an independent
logical drive. JBOD does not provide data redundancy.

A.3.3 RAID 0
RAID 0 implements block striping where data is broken into logical
blocks and striped across several drives. Although called “RAID 0,”
this is not a true implementation of RAID because there is no
facility for redundancy. In the event of a disk failure, data is lost.
In block striping, the total disk capacity is equivalent to the sum of
the capacities of all fibre drives in the array. This combination of
drives appears to the system as a single logical drive.
RAID 0 provides the highest performance without redundancy. It is
fast because data can be simultaneously transferred to/from multiple
disks. Furthermore, read/writes to different drives can be processed
concurrently.

A.3.4 RAID 1
RAID 1 implements disk mirroring where a copy of the same data is
recorded onto two sets of striped drives. By keeping two copies of
data on separate disks or arrays, data is protected against a disk
failure. If, at any time, a disk on either side fails, the remaining
good disk (copy) can provide all of the data needed, thus preventing
downtime.
In disk mirroring, the total disk capacity is equivalent to half the
sum of the capacities of all fibre drives in the combination. Thus,
combining four 1GB fibre drives, for example, would create a single
logical drive with a total disk capacity of 2GB. This combination of
drives appears to the system as a single logical drive.
NOTE
One drawback to RAID 1 is that it does not allow running
expansion. Once a RAID 1 array has been created, to expand it,
the data must be backed up elsewhere before a new drive can be
added. Other RAID levels permit running expansion.
RAID 1 is simple and easy to implement; however, it is more
expensive as it doubles the investment required for a non-redundant
disk array implementation.

In addition to the data protection RAID 1 provides, this RAID level
also improves performance. In cases where multiple concurrent
I/Os are occurring, these I/Os can be distributed between disk
copies, thus reducing total effective data access time.
A.3.5 RAID 1(0+1)
RAID 1 (0+1) combines RAID 0 and RAID 1 – mirroring and disk
striping. RAID (0+1) allows multiple drive failure because of the
full redundancy of the hard disk drives. If more than two hard disk
drives are chosen for RAID 1, RAID (0+1) will be performed
automatically.

Figure A-5: - RAID 1(0 + 1)
IMPORTANT:
RAID (0+1) will not appear in the list of RAID levels supported by
the controller. If you wish to perform RAID 1, the controller will
determine whether to perform RAID 1 or RAID (0+1). This will
depend on the number of drives selected for the logical drive.
A.3.6 RAID 3
RAID 3 implements block striping with dedicated parity. This
RAID level breaks data into logical blocks, the size of a disk block,
and then stripes these blocks across several drives. One drive is
dedicated to parity. In the event a disk fails, the original data can be
reconstructed from the parity information.
In RAID 3, the total disk capacity is equivalent to the sum of the
capacities of all fibre drives in the combination, excluding the parity
drive. Thus, combining four 1GB fibre drives, for example, would
create a single logical drive with a total disk capacity of 3GB. This
combination appears to the system as a single logical drive.
RAID 3 provides increased data transfer rates when data is being
accessed in large chunks or sequentially. However, in write
System Features
A-7
operations that do not span multiple drives, performance is reduced
since the information stored in the parity drive needs to be recalculated and re-written every time new data is written to any of the
data disks.

A.3.7 RAID 5
RAID 5 implements multiple-block striping with distributed parity.
This RAID level offers the same redundancy available in RAID 3;
though the parity information this time is distributed across all disks
in the array. Data and relative parity are never stored on the same
disk. In the event a disk fails, original data can be reconstructed
using the available parity information.

RAID 5 offers increased data transfer rates when data is accessed in
large chunks (i.e., sequentially) and reduced data access time for
many simultaneous I/O’s when they do not span more than one
drive.
A.3.8 Spares
RAID implementations include one other basic concept that needs to
be introduced at this point: spare drives. RAID levels that have
redundancy, levels 1, 3, and 5, all allow users to include a drive as a
“spare.” Spare drives are installed, fully functioning, “hot-ready”
hard drives which a RAID controller will use to replace a failed
drive as soon as the failure is detected. The purpose of this,
obviously, is to enhance the existing fault-tolerant capabilities of a
RAID array.
A.4 Redundant Features
A.4.1 Dual-Active Redundant Controllers
The ER2510Fcontrollers can be configured in a dual-active
redundant mode. If one controller fails the other controller will
System Features
A-9
automatically take over the workload of the failed controller and
manage the entire storage system. Both the cache writes and
configuration data are fully synchronized. Failover and failback
operations are completely transparent to the host and IOs are moved
between the controllers without any user intervention.
A.4.2 Redundant Data Paths
Dual data paths can be connected to the JBOD enclosure/HBA from
the ER2510FS RAID Controller Head. If one data path should fail
the data can be transmitted through the alternative data path. Full
host side redundancy can be achieved if two host channels are
connected to two separate HBAs and then to the Host computer.
A.5 Fault Tolerance
A.5.1 Hot-swappable active components
All the active components; including the controller modules, power
supply units (PSU), the IO modules, the battery back up units
(BBU), the maintenance modules and the LED modules; are hotswappable. If any of these components fail, they can be replaced
without turning off the system or disrupting the smooth operation of
the system.
A.5.2 Global and Local Spares
Both Global and Local (dedicated) spares are supported. The
controller(s) will automatically disconnect from a failed drive and
start to rebuild data on the spare drive. The spare drive will then
replace the failed drive.
A.5.3 Hot-Swapping of Drives
A failed drive in the JBOD storage enclosure can be exchanged
without turning off the system or interrupting the smooth operation
A-10
System Features
of the system. Once the failed drive is replaced the data will be
rebuilt in the background. Hot-swapping is supported through the
automatic disconnection from a failed drive and the detection of a
reserve drive. All these failure recovery procedures are completely
transparent to the host.
A.5.4 S.M.A.R.T. Support
S.M.A.R.T (Self Monitoring Analysis and Reporting Technology) is
supported with configurable reaction schemes. Users may select
different reaction schemes for immediate prevention against
S.M.A.R.T. detected errors. Available options include: detect only,
clone and replace, and perpetual clone. A faulty drive can be cloned
to an active spare upon the discovery of errors.

A.6 SAN Features
A.6.1 Logical Unit Numbers
Up to 128 Logical Unit Numbers (LUNs) are supported. Each LUN
can be mapped to a logical unit (drive or volume). The LUN
provides the logical unit with a unique signifier which enables the
controllers to identify it.
System Features
A-11
A.6.2 LUN Masking
Both the IFT5251F-4 and IFT5251F-6 RAID Controllers support
LUN Masking. This enables a specific LUN to be uniquely assigned
to a specific host. The host will then only be able to access the
LUNs which are assigned to it, all the other LUNs will be “hidden”.
A.7 Mechanical Features
A.7.1 Modular Design
The modular design of the ER2510FS simplifies the installation
process and makes these systems easy to upgrade and maintain. All
the active components are modular and are therefore easy to replace.
A.7.2 Hot-swap mechanisms
Special hot-swap mechanisms have been designed to facilitate the
easy removal and replacement of the hot-swappable active
components.
A.7.3 Cableless Design
All the active components are cableless. This simplifies the
installation of the system. Users do not have to be concerned with
connecting any cables.
A.7.4 Slide rails and support handles
Both support slide rails and support handles can be used to mount
the system into a standard Cabinet. The slide rails and handles
ensure simplified installation and solid support.
A-12
System Features
A.7.5 Dummy Canisters and Brackets
The ER2510FS comes in four different models. Some of these
models come with only four IO modules and one controller module.
To ensure the smooth running of these systems, dummy canisters
and brackets have been designed. Once installed, these dummy
canisters and brackets will ensure that the air impedance within the
chassis is properly regulated and the system cooled sufficiently.
