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.

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.

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.

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.

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.

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.

Front Bezel LEDs and Reset Button Identification
The imageRAID Controllers provide monitoring data for its environmental
condition and logical arrays. They communicate that data to the front bezel LEDs,
third-party configuration and monitoring software such as StorView, and the
VT-100 firmware-based interface for management and monitoring. (Refer to the
software user’s guide for configuration, management, and monitoring of the
controllers and logical arrays.)
