RAID Subsystem DVA-16K | Installation Manual
Introduction
This manual covers the DVA-16K series of RAID subsystems.
The 3U profile, SCSI-320 to SATA-II, RAID subsystem is capable of a high-performance storage
operation that has been specifically designed to meet the rapidly changing demands and
needs of today’s storage networks. The RAID subsystem is rigorous and durable that can be
easily configured and operated.
Fully featured RAID redundancy provides advanced data protection and ensures that the complete range of RAID levels 0, 1(0+1), 3, 5, 10, 30, 50 and JBOD are supported. Complete system redundancy, through fully redundant data paths and hot-swappable devices ensures the
overall protection of data. A long list of sophisticated firmware functions (multi-subsystem
configuration, dedicated/ global hot-spares, battery protected disk cache, automatic background rebuild, online drive expansion, intelligent drive handling, media scan, task-scheduler,
remote and real-time subsystem monitoring, and more). Further the system guarantees the
overall availability of valuable data.
System integrators, using the RAID series, will be able to rapidly develop SCSI-320 solutions.
This will help save both development time and the associated R&D costs, providing a competitive edge in the marketplace. For users, the modular nature of the series minimizes the total
management cost of building a large storage network with a RAID subsystem.
The enhanced 3U RAID storage subsystem chassis is a 3U metal chassis divided into front and
rear sections, which are respectively accessed through front and rear panels. Pre-drilled
mounting holes in the sides of the 3U RAID subsystem enclosure allow you to attach separately purchased slide rails so that you can install the enclosure into a rack or cabinet. The
modular design of the active components facilitates their easy installation and removal. Hotswap mechanisms are incorporated to eliminate power surges and signal glitches that might
happen while removing or installing these modules.
2.1
Product Overview
This manual introduces the SCSI-320 to SATA-II RAID subsystem shown in Figure 2.1.
Fig. 2.1
RAID Subsystem
The RAID subsystem comes with two (2) 320MB/second SCSI (SCSI-320) host channels. This
high-density subsystem supports up to sixteen (16) hot swappable, SATA-II hard drives in a 3U
profile. The core of the subsystem is the RAID controller board with the ASIC266 and a preinstalled 256MB DDR RAM DIMM module with support for capacities up to 1GB. The new
SCSI-320 host channel features packet protocol, and its reduction in command overhead provide increased speed without bandwidth issues.
The metal container in which the controller board is pre-installed is referred to as the “controller module.” The controller module is comprised of a PCB board, a rear faceplate, and a
metal canister. The controller module is accessed through the rear of the RAID subsystem. A
battery backup unit (BBU) is installed in the upper left side of the controller module when
viewed from the rear of the subsystem. The BBU is also accessible and hot swappable through
the rear panel of the RAID subsystem.
Two (2) dual-stacked VHDCI SCSI connectors connect the RAID controller to single or dual
hosts and cascade external devices. Two (2) hot-swappable cooling modules protect the subsystem from overheating, and two (2) hot-swappable power supply unit (PSU) modules proF.01U.027.799 | V1 | 2006.05

vide constant power to the subsystem. The modular nature of the subsystem and the easy
accessibility to all major components ensure the ease of the subsystem maintenance.
NOTICE!
i
On receiving and unpacking your subsystem, please check the package contents against the
included Unpacking Checklist. If any modules are missing, please contact your subsystem vendor immediately.
2.2
Management
The RAID subsystem can be managed using either the firmware or the Bosch RAIDWatch webbased GUI. The firmware can be accessed by using either the LCD panel (see Figure 2.2)
located at the front of the subsystem or a terminal emulation program installed on an external
computer and connected to the COM1 on the controller module’s rear panel (see Figure 2.2)
with the provided serial cable.
Fig. 2.2 Controller Module Rear Panel
If web-based management is desired, connecting the subsystem to the world wide web
through the Ethernet port on the controller module’s rear panel, (See Figure 2.2) allows you to
manage the RAID subsystem by Bosch RAIDWatch management software.
2.3
Best Practices
2.3.1
Avoiding Points of Failure
To achieve maximum uptime when connecting a RAID subsystem into a storage environment,
it is imperative that points-of-failure are avoided. The best way to avoid them is through the
use of redundant components. As stated above, the cooling modules and PSU modules on the
subsystem are fully redundant. Using dual-redundant data paths will further minimize the possibility of system downtime.
2.3.2
Dual-Redundant Data Paths
When connecting the RAID subsystem to a server, dual-redundant data paths are recommended. If one (1) data path fails, a second data path can be used to transmit data. Dualredundant data paths are supported by both the host and drive channels.
2.3.3
ID Mapping
Host ID mapping is flexible, in the sense that the same array can be associated with different
host ID/LUNs, allowing the host clustering configurations. Drives on different channels can
then be grouped into an array, and the array has its unique volume size, stripe size, and optimization mode. Arrays of different RAID levels can be striped together into logical volumes,
making management of huge volume size an easier task.

Drive Trays
Fig. 2.8 Drive Tray Front View
The RAID subsystem comes with sixteen (16) drive trays (See Figure 2.8) designed to accommodate separately purchased standard 1-inch pitch, 3.5-inch disk drives. The drive bays are
easily accessible from the front of the enclosure. Two (2) LEDs on the front of the tray indicate the drive status. A key-lock on each drive tray secures the hard drive in place, while an
easily accessible button ensures fast and efficient drive hot-swapping.
CAUTION!
Be careful not to warp, twist, or contort the drive tray in any way (e.g., by dropping it or resting heavy objects on it). The drive tray has been customized to fit into the drive bays in the
RAID subsystem. If the drive bay superstructure is deformed or altered, the drive trays may
not fit into the drive bay.
2.5.3
The RAID Controller Module
The RAID controller module contains a main circuit board, a preinstalled 256MB capacity or
above DDR RAM DIMM module and the controller module interfaces. The controller module
contains no user-serviceable components. Except when installing/upgrading the cache memory inside, the controller module should never be removed or opened.
CAUTION!
Although the RAID controller can be removed, the only time you should touch the controller
itself is to install the memory modules. The RAID controller is built of sensitive components
and unnecessary tampering can damage the controller.
The heart of the RAID controller subsystem is the 320MB per second SCSI-to-SATA controller
board. The controller comes with two (2) pre-set SCSI-320 host channels, CH0 and CH1. The
subsystem connects to the host through a VHDCI SCSI input connector, while the output connector is ready to connect external devices. (See Figure 2.9)
The docking connector at the rear of the controller board is used to connect the controller
module to the backplane board. A DDR RAM DIMM socket is strategically placed in an easily
accessible location on the controller board for easy insertion of the DDR RAM DIMM module.
2.5.4
Controller Module Interfaces
All external interfaces that connect to external devices are located on the controller module
rear panel shown in Figure 2.9. The interfaces are listed below.

Supply for the instructions on connecting a UPS.
•
Levers: Two (2) levers located in the sides of the controller board rear panel provide easy
controller module installation and secure the controller module in place.
2.5.5
DIMM Module
The controller module comes with a pre-installed 256MB capacity or above DDR RAM DIMM
module and can support capacities up to 1GB. The DIMM module is placed in an easily
accessed location on the controller board. However, when the DIMM module is being
changed, the controller module must be removed from the subsystem chassis.
2.5.6
Battery Backup Unit (BBU)
The Li-ION battery backup unit (BBU) (see Figure 2.11) sustains cache memory after a power
failure. It is installed on the upper left side of the controller module in the rear subsystem
chassis.
Fig. 2.10
BBU Module
In accordance with international transportation regulations, the BBU is only charged to
between 35% and 45% of its total capacity when shipped. Therefore, after powering on the
subsystem (see Section 5.4 Power On) the BBU must be charged to its full capacity. It normally
requires approximately twelve (12) hours for the battery to be fully charged. If the battery is
not fully charged after twelve (12) hours, there is a problem with the BBU and you should contact your subsystem vendor immediately. While the battery is being charged, the LED on the

BBU rear panel and the fifth LED on the rear panel of the controller module will flash slowly.
(See Section 4.2.6 BBU Module LED for details on the LED indicators.) You can check the status of the battery’s charge via Bosch RAIDWatch or the firmware.
2.5.7
Power Supply Units
The RAID subsystem is equipped with two (2) redundant, hot-swappable, 460W PSUs, which
are located at the rear of the enclosure. (See Figure 2.6) The PSU is permanently mounted
into a 2U (dual-level) bracket especially designed to house both the PSU and a cooling module, which is mounted in the lower part of the 2U bracket. Hot-swapping the PSU requires the
removal of the cooling module.
As shown in Figure 2.11, each PSU comes with a single power socket for power cord plug-in,
and a power switch on the right to turn the subsystem on and off. Two (2) embedded cooling
fans provide sufficient airflow to keep the PSU cool. A single LED indicates the PSU status.
When any power supply failure occurs, such as over-voltage or fan failure, the LED shines red.
A handle at the back of the PSU has been especially designed to enable you to remove the
PSU from the subsystem while the subsystem is online. This should only be done if the PSU
has failed and needs to be replaced.
A retention screw at the top of the PSU module secures the PSU to the enclosure. To remove
the PSU, the retention screw must be removed first. When installing a new PSU module, make
sure that the retention screw has been firmly secured.
Fig. 2.11
PSU Module
For the PSU specifications, please refer to Section 7 Appendix: Specifications.
2.5.8
Cooling Modules
The RAID subsystem is equipped with two (2) 1U, dual-fan, redundant, hot-swappable cooling
modules. They are installed in the cooling module slots located in the lower section of the
PSU modules (see Figure 2.12.) The two (2) 9.7cm fans housed in each cooling module provide two (2) fan speeds. When the subsystem is running in normal ambient temperature, the
fans operate at the lower speed. When the temperature reaches the temperature threshold,
the fans automatically change to high speed to generate more cooling air from the front to the
rear of the subsystem to extract the heat generated by the hard drives.
Cooling module specifications are listed in Section 7 Appendix: Specifications.

hear an audible alarm from the RAID subsystem, it is imperative that you determine the cause
and rectify the problem immediately.
Event notification messages indicate the completion or status of array configuration tasks and
are always accompanied by two (2) or three (3) successive and prolonged beeps.
CAUTION!
Failing to respond when an audible alarm is heard can lead to permanent damage of the RAID
subsystem. When an audible alarm is heard, rectify the problem as soon as possible.

Hot-swappable Components
Hot-swap Capabilities
The RAID subsystem comes with a number of hot-swappable components. A hot-swap component is one that can be exchanged while the subsystem is still online without affecting the
operational integrity of the subsystem. These components should only be removed from the
subsystem when they are being replaced. At no other time should these components be
removed from the subsystem.

•
2.7.3
Power supply units (PSUs)
Cooling modules
BBU
Hard drives
Normalized Airflow
Proper subsystem cooling is referred to as “normalized” airflow. Normalized airflow ensures
the sufficient cooling of the subsystem and is only attained when all components are properly
installed. Therefore, a failed component should only be hot-swapped when a replacement is
available. If a failed component is removed but not replaced, permanent damage to the subsystem can result.

Safety Precautions
Precautions and Instructions
1.
Be sure the correct power range (100-120 or 200-230VAC) is supplied by your rack cabinet or power outlet.
2.
Thermal notice: All drive trays (even if they do not contain a hard drive) must be installed
into the enclosure. Leaving a drive bay or module slot open will greatly affect the airflow
efficiency within the enclosure, and will consequently lead to system overheating. Keep a
faulty module in place until you have a replacement unit and you are ready to replace it.
3.
An enclosure without disk drives can weigh over 24 kilograms. Two (2) people are
required to install or relocate the subsystem. Drives should be removed from the enclosure before moving the subsystem.
4.
Airflow considerations: The subsystem requires an airflow clearance especially on the
front and rear. For proper ventilation, a minimum of 2.5cm is required between the front
of the enclosure and rack cover; a minimum of 5cm is required between the enclosure
and end of the rack.
5.
Handle the system modules by the retention screws, eject levers, or the module’s metal
frame/face plate only. Avoid touching the PCB boards and connector pins.

19
None of the covers or replaceable modules should be removed in order to maintain compliance with safety, emission, or thermal requirements.
7.
Always secure every enclosure module by its retaining screws or make sure it is held in
place by its latches.
8.
Always make sure the subsystem has a safe electrical earth connection via power cords
or chassis ground by the rack cabinet.
9.
Be sure that the rack cabinet in which the subsystem chassis is to be installed provides
sufficient ventilation channels and airflow circulation around the subsystem.
10. Provide a soft, clean surface to place your enclosure on before working on it. Servicing
the enclosure on a rough surface may damage the finish of the chassis.
11. If it is necessary to transport the subsystem, repackage all drives and replaceable modules separately.
3.3.2
Static-free Installation
Static electricity can damage the system’s electronic components. To prevent ESD damage to
any of the components, follow these precautions before touching or handling them:
•
Discharge the static electricity accumulated in your body by wearing an anti-static wristband.
•
•
Avoid carpets, plastic, vinyl, and Styrofoam in your work area.
Handle all components by holding their edges or metal frames. Avoid touching the
exposed circuitry on PCB boards and connector pins.

A detailed packing list can be found in your product shipping package or product CD.
Rack/Cabinet Installation
The RAID subsystem has been designed to fit into a standard cabinet or rack. Two (2) slide
rails are available for installing the subsystem into a rack or cabinet. Please contact your system vendor for further details. The subsystem should be installed in the rack or cabinet before
the hard drives and the drive trays are installed. If the drive trays with the associated hard
drives are installed, the subsystem will be too heavy to mount into a rack or cabinet. When
installing the subsystem into a rack or cabinet it is advisable that three people assist in the
mounting process.
To install the subsystem into a rack or cabinet please refer to the installation instructions that
came with the slide rails.
3.7
Drive Tray Installation
Once the hard drives have been installed in the drive trays, the drive trays can be installed into
the RAID subsystem.
CAUTION!
All drive trays must be installed into the enclosure even if they do not contain a hard drive. If
the trays are not installed into the enclosure, the ventilation required for cooling will not be
normalized and the subsystem will overheat.
1.
Make sure the key-lock is in the unlocked position, i.e., the groove on its face is in a horizontal orientation. If the groove is in a vertical position, as shown in Figure 3.1, then the
key-lock is locked and the front flap on the drive tray cannot be opened.

Subsystem Monitoring
4.1
Subsystem Monitoring Overview
Subsystem Monitoring | en
23
The RAID subsystem is equipped with a variety of self-monitoring features that help to keep
subsystem managers informed of the subsystem operational status. These monitoring features provide vital feedback to help you maintain the operational integrity of the subsystem.
Prompt response to warnings and subsystem component failure notifications will improve the
overall operation of the subsystem and help ensure the longevity of the RAID subsystem.
Self-monitoring features include:
•
Firmware (FW): The controllers in the RAID subsystem come with pre-installed FW, which
can be accessed using either the LCD panel or a PC Hyper Terminal. The RAID subsystem
can be connected to a PC hyper-terminal through the COM ports. Device status information can be obtained from the FW.
•
Bosch RAIDWatch: Bosch RAIDWatch is a fully integrated, Java-based, Graphics User
Interface (GUI) that came with the subsystem and can be used to monitor and maintain
the subsystem and the RAID controllers using your web browsers. The LAN port at the
back of each controller module enables you to use an Ethernet cable to connect to the
subsystem.
The Bosch RAIDWatch Panel View can be customized to show a direct representation of
the subsystem in the content panel of the Bosch RAIDWatch screen. Panel View allows
you to quickly determine the operational status of critical components.
•
Configuration Client: The Configuration Client is a powerful module that runs as a background Disk and Executive Monitor (DAEMON) independent from Bosch RAIDWatch that
can be installed redundantly on different hosts. It is used for event notification via email,
fax, LAN broadcast, SNMP traps, MSN Messenger, ICQ, SMS short messages, and the
configuration utility screen. The Configuration Client helps prevent blind time and keeps
you constantly informed as to the status of the storage management subsystem.
•
LEDs: Device-status-indicating LEDs are located on all active components. These LEDs
inform you of the integrity of a given component or a given link. You should become familiar with the different LEDs that are present on the subsystem and be aware of their functions.
•
Audible alarm: An audible alarm is present on the subsystem controller board and will be
triggered if any of a number of threatening events occur. These events usually jeopardize
the functional and operational integrity of the controller board and must be heeded at all
times. Events such as a breaching of the temperature threshold will trigger the alarm. If a
subsystem manager is present, the manager should use either the LCD panel or the PC
hyper-terminal to determine the cause of the alarm and take the appropriate corrective
measures. (See Section 4.3 Audible Alarm)
•
I2C: The I2C bus monitors the operational integrity of the PSUs, cooling modules, and
RAID controller board temperature.
Subsystem monitoring is a necessary part of subsystem management. If failure events or other
disruptive events are detected and reported, the subsystem managers must take the appropriate action to rectify the problem. Failure to act in a properly specified manner to a system
event (like overheating) can cause severe and permanent damage to the subsystem.

high ambient temperature or the failure of any cooling or PSU module, the system will turn the
cooling fans to high speed to extract more heat. Once the ambient temperature cools down to
normal or the cooling or PSU modules have been replaced, the cooling fans will return to low
speed.
4.3
Audible Alarm
Different controller environmental and operational parameters (like temperature, etc.) have
been assigned a range of values between which they can fluctuate. If either the upper or lower
thresholds are exceeded, an audible alarm will automatically be triggered. The alarm will also
be triggered when an active component on the RAID subsystem fails. If the RAID subsystem
manager is onsite and hears an alarm, the manager must read the error message on the LCD
screen or PC terminal to determine what has triggered the alarm. After determining what has
occurred, the RAID subsystem manager must take appropriate actions to rectify the problem.
CAUTION!
If an alarm is triggered it is necessary for you to determine the problem. If the audible alarm is
ignored and the problem is not rectified, unexpected damages may occur.

Subsystem Connection and Operation
This chapter introduces sample topologies, daisy-chaining, and external device connections
for the RAID subsystem and discusses both the power on and power off procedures.
5.1
SCSI Connection Overview
The RAID subsystem supports two (2) SCSI channels and two (2) dual-stacked SCSI connectors using SCSI-320 (also known as Ultra-320 SCSI), the latest iteration of the SCSI bus standard. SCSI-320 enables maximum data transfer rates of up to 320MB/second per channel
between the host computers and the RAID subsystem. This is twice as fast as the Ultra-160
standard, allowing users to store data at the fastest SCSI speeds available.
5.1.1
SCSI Cables
One (1) SCSI cable is used for each RAID subsystem for host connection. A second SCSI cable
is used to connect the second host channel. Use only high quality SCSI-320 cables from a reputable manufacturer. To ensure optimum performance, it is necessary to use proper, high
quality, durable SCSI-320 cables. Failure to do so will result in downgraded performance.
5.1.2
SCSI Port on the Controller Rear Panel
The RAID subsystem is equipped with two (2) dual-stacked VHDCI SCSI connectors on the
back of the enclosure for connecting the subsystem to a host computer and/or to daisy-chain
other RAID subsystems. (See Figure 5.1) The connectors on the bottom of the controller rear
panel are for data input and the connectors on the top are for data output.
Fig. 5.1 SCSI Connectors on the Controller Rear Panel
5.1.3
SCSI Termination
Correct SCSI termination procedures require that the last device on the SCSI bus be terminated. If the last device is not terminated or if devices other than the last are terminated,
erratic SCSI bus behavior may occur.
An auto-detection, on-board terminator is built into the RAID subsystem. You do not need to
install an external terminator when a subsystem acts as the last device in the daisy chain configuration. The on-board terminator default is enabled. If the subsystem is not the last device
in the daisy chain configuration, the terminator will be automatically disabled. Although it is
not recommended, if you prefer to disable the firmware setting for the on-board terminator
using the LCD keypad panel on the subsystem, RS232C terminal session, or Bosch RAIDWatch
management software, the auto-detection function is also disabled.
Typically, the host computer or host adapter (SCSI card inside the PC) is the first device and
some are already terminated. When installing the RAID subsystem on a SCSI bus with other
devices, be sure to observe the above rules regarding all devices on the SCSI bus. Consult
your host computer and/or host adapter manual for additional information on correct termination procedures.

5.2
It is recommended not to change the firmware default setting for the SCSI terminator so the
auto-detection function can operate.
Host Connection Topology
There is no direct association between host ports and drive channels. Drives are associated
with host port IDs as the logical configuration of drives, e.g., a logical drive. A logical drive can
be composed of drives on different drive channels, and a logical drive can be associated with
target IDs on different host ports.
Drive access contention (that may happen when two (2) host computers can access the same
array) and data-path failover activities should be handled by a third-party software running on
host computer(s).
RAID subsystem host channel SCSI connectors are connected to the servers via host bus
adapters (HBAs) that have been installed on the host computer(s).
•
Single server connection: If a single logical drive is mapped to a single server, a RAID
management software should be installed in the server to execute RAID functionality.
•
Multiple server connection: If a single logical drive is mapped to two (2) separate servers
through dual-redundant data paths, separately purchased, third-party multipathing and
clustering software must be installed on both servers. The clustering software will ensure
that if one (1) server or the data path to a single server fails, the second server will continue to provide access to the data.

Dual Hosts
Fig. 5.3 Dual Host Connection
In the example shown in Figure 5.3, the two (2) SCSI ports on the RAID subsystem are connected to two (2) different host computers and an Ethernet cable connects both computers
to each other. This configuration provides both path and host computer redundancy. If one of
the host channels becomes disconnected for some reason, or the cable connecting one of the
host ports to the host computer is damaged, the second path can transmit data from the subsystem to the host computer. Similarly, in the clustered hosts configuration, the same array
can be accessed through different data paths and downtime will be minimized.

Daisy Chain
5.3.1
Daisy Chain Topology
The RAID subsystem offers the flexibility to daisy chain additional RAID subsystems to meet
increasing storage needs. In a daisy chain topology, the RAID subsystem can be connected to
each other. The IN ports on the first subsystem are both connected to separate SCSI-320 host
computers. The OUT ports on the first subsystem are connected to the IN ports on the second
subsystem. This process is repeated for the third subsystem.

Connect the RAID subsystem to the host computer. Use the VHDCI to VHDCI SCSI cable
that was provided in the packaging box. Attach one end to the host computer and the
other end to the SCSI IN port on the back of the RAID subsystem.
2.
Daisy chain subsystems. If you wish to connect more than one subsystem, an extra VHDCI
to VHDCI SCSI cable is required. Attach one end of the cable to the SCSI OUT port and
the other end to the SCSI IN port in the next subsystem.
3.
Assign chassis IDs. Each chassis must be assigned a unique chassis ID before being powered on. The chassis ID for the first RAID subsystem is 0. The chassis IDs for the subsystems connected to the first RAID subsystem are from 1 to 16. You can assign chassis
IDs through the LCD panel on the subsystem, firmware, or Bosch RAIDWatch management software. (See Figure 5.4)
4.
Create redundant host paths. If access to data is a critical requirement, redundant data
paths to different LDs (logical drives) or logical volumes (LVs) can be created. To do this,
logical units (LDs or LVs) are mapped to both host channels (CH0 and CH1 in Figure 5.4.)
This will ensure that if one host computer fails, the second host computer will be able to
access the logical units on that host computer.
NOTICE!
i
5.4
To create dual redundant data paths on the host side, it is necessary to install third-party
failover software on the host computer.
Power On
Once all of the components have been installed in the RAID subsystem and the host channels
have been connected to the host, the subsystem can be powered on.

Constant monitoring and maintenance of your RAID subsystem minimizes subsystem downtime and preserves the working integrity of the system for a longer period of time. If any of the
subsystem components fail, they must be replaced as soon as possible.
CAUTION!
Do not remove a failed component from the subsystem until you have a replacement on hand.
If you remove a failed component without replacing it, the internal airflow will be disrupted
and the system will overheat, causing damage to the subsystem.
All of the following components can be replaced in case of failure:

General Notes on Component Replacement
•
With the exception of the RAID controller module, all of the components on the RAID subsystem, including the PSU modules, cooling modules, and drive trays, are hot-swappable
and can be changed while the subsystem is still in operation.
•
Qualified technicians who are familiar with the RAID subsystem should be the only ones
who make component replacements. If you are not familiar with the RAID subsystem or
with RAID subsystem maintenance in general, it is strongly advised that you refer RAID
subsystem maintenance to a suitably qualified maintenance technician.
•
Normalized airflow depends upon the presence of all subsystem components. A subsystem component, even if it has failed, should not be removed from the subsystem until
a replacement is readily at hand and can be quickly installed. Removing subsystem components without a replacement can lead to permanent subsystem damage.
•
When replacing any hot-swappable component, caution should be taken to ensure that
the components are handled in an appropriate manner. Rough or improper handling of
components can lead to irreparable damage.
•
When removing a controller module from the subsystem, ensure that the power has been
turned off and that all precautionary measures, without exception, are adhered to. The
controller board and the I/O board on which it is mounted are very sensitive components
and can be easily damaged.
6.2
Replacing Controller Module Components
The controller module in the RAID subsystem consists of the following replaceable components:
•
•
DDR RAM DIMM module
Controller module
If any of these components fail, it must be replaced. To replace any of these components, the
system power must first be turned off, and the controller module must be removed from the
RAID subsystem.

Controller Module Maintenance Overview
•
The controller module contains a DDR RAM DIMM module. When replacing the controller
module, the DIMM module must be removed from the old controller module and reinstalled onto the new controller module.
•
When replacing the controller module, always remember that the controller board is one
of the most sensitive components in the RAID subsystem. All previously stipulated safety
precautions (see Section 3.3 Safety Precautions) must be strictly adhered to. Failure to
adhere to these precautions can result in permanent damage to the controller board,
resulting in lengthy delays for the end user.
•
Prior to replacing the controller module, it is imperative for your own safety to be sure
that no power is being supplied to the system.
6.2.2
Removing the Controller Module
To remove the controller module:
1.
Make sure there is no data access to the subsystem to avoid losing any data. Use the software provided on the host computer to stop all I/O accesses to the subsystem.
2.
Power off the subsystem. Be sure to flush all cache data before powering off the subsystem. Turn off both power switches on the rear of the subsystem.
3.
Disconnect all cables from the controller module. These include the SCSI cables connecting to input/output SCSI connectors, Ethernet cable connected to the LAN port, and any
cables connected to the COM ports.
4.

removed and the new one installed. Replacement and installation instructions are described
fully below.
6.3.1
DIMM Module Considerations
If the memory module on the controller module is going to be replaced, the following issues
must be considered when purchasing a replacement DIMM module:
•
Pre-installed DDR RAM DIMM module: The RAID subsystem comes with a 256MB capacity
or above DDR RAM DIMM pre-installed on the controller board and can support up to
1GB capacity. If you wish to change the size of the DDR DIMM, then a new DIMM must be
installed.
•
Purchasing considerations: When purchasing a DDR RAM DIMM module to install on the
RAID subsystem controller board, contact your subsystem vendor for an updated list of
compatible DIMM modules.
•
DDR RAM DIMM module supported: The RAID subsystem supports DDR RAM DIMM modules with memory capacities between 256MB and 1GB.
•
Installation considerations: When installing the DDR RAM DIMM module, it is necessary to
remove the controller module. The controller board is more susceptible to damage than
the other components and must be handled with extreme care.
•
Secure installation: When replacing the DIMM module, make sure that the new DIMM
module is firmly in place prior to re-installing the controller module. If the DIMM module
is not firmly in place, the subsystem will not run and the whole procedure must be
repeated.
6.3.2
DIMM Module Replacement Procedure
NOTICE!
i
If you are going to replace or upgrade a DIMM module, please follow the instructions below. If
you do not want to replace or upgrade a DIMM module and would like to install a controller
module, please go to Section 6.2.3 Replacing the Controller Module.
If a DIMM module fails or if a DIMM module with a higher memory capacity is required, the
onboard DIMM module must be replaced. To replace the DIMM module:
1.
Remove the controller module. (See Section 6.2.2 Removing the Controller Module)
2.

6.4
Replacing a Faulty BBU Module
The BBU consists of a bracket, a battery pack, and a PCB board that connects to the backplane board. If a BBU was installed and has failed, it should be replaced. To install or replace
a BBU, please follow these steps.
6.4.1
BBU Warnings and Precautions
•
Install or replace the BBU supplied by your subsystem vendors only. Use of battery cells
provided otherwise will void our warranty.
•
Always dispose of discharged or used batteries in an ecologically responsible manner.
Dispose used BBU at authorized battery disposal sites only.
•
Do not use nor leave the BBU near a heat source. Heat can melt the insulation and damage other safety features of battery cells, possibly leading it to acid leak, and result in
flames or explosion.
•
Do not immerse the BBU in water nor allow it to get wet. Its protective features can be
damaged. Abnormal chemical reactions may occur, possibly causing functional defects,
acid leak, and other hazardous results.
•
Do not disassemble or modify the BBU. If disassembled, the BBU could leak acid, overheat, emit smoke, burst and/or ignite.
•
Do not pierce the BBU with a sharp object, strike it with a hammer, step on it, or throw it.
These actions could damage or deform it, internal short-circuiting can occur, possibly
causing functional defects, acid leak, and other hazardous results.
•
If the BBU leaks, gives off a bad odor, generates heat, becomes discolored or deformed,
or in any way appears abnormal during use, recharging or storage, immediately remove it
from the subsystem and stop using it. If this is discovered when you first use the BBU,
return it to Bosch or your system vendor.
6.4.2
Procedure
NOTICE!
i
The BBU is hot-swappable and can be replaced while the subsystem is running. However, a
new module will only be recognized after a subsystem reset. Carefully select the time when
the reset will be made in order to minimize the overall disruption to service.
1.
Remove the faulty BBU from the chassis. Loosen the two (2) retention screws located on
both sides of the BBU, then pull out the BBU. (See Figure 6.8)

The life expectancy of a BBU is approximately 500 cycles. Follow the procedures above to
replace an old BBU with a new BBU in order to maintain fault-tolerant subsystem functionalities.
6.5
Replacing a Faulty PSU Module
6.5.1
PSU Module Overview
•
Two (2) redundant PSU modules: The RAID subsystem is preinstalled with two (2) 460W,
fully redundant, hot-swappable PSU modules. These modules are located at the rear of
the subsystem.
•
PSU bracket: Each PSU module is permanently mounted in a two-level steel bracket, creating a single unit. The PSU is located in the upper level and a removable cooling module
is mounted in the lower level. When removing the PSU from the subsystem, the cooling
module is also being removed.
•
PSU printing mark: Before you insert a new PSU, be sure that it has the same printing
mark on its handle as that shown on the handle of a remaining PSU. Double-check to
avoid mixing a PSU of previous series. (See Figure 6.10)

Label on the PSU Handle
Immediate replacement: When a PSU fails, it should be replaced immediately. However,
do not remove the PSU module unless a replacement is readily available. Removing a PSU
without a replacement will cause severe disruptions to the internal airflow and the subsystem will overheat, possibly causing irreparable damage to some of the subsystem
components.
6.5.2
Replacing the PSU Module
CAUTION!
Although the PSU modules are fully redundant, it is not advisable to run the RAID subsystem
with a single PSU module for an extended period of time. If the second PSU module fails, the
subsystem will be shut down.

Cooling Module Maintenance
6.6.1
Cooling Module Overview
•
Redundant cooling modules: The RAID subsystem is equipped with two (2) redundant,
hot-swappable, dual-blower cooling modules located on the lower level of the subsystem
rear panel. These cooling modules control the internal operational temperature of the
subsystem and therefore their working integrity should be maintained at all times.
•
Detecting a failed cooling module: If a cooling module fails, the LED located at the back
of the module, an audible alarm, the firmware, the Bosch RAIDWatch panel view, or the
Configuration Client can notify you.
•
Replacing a cooling module: Once you are notified that a cooling module has failed, it
should be replaced as soon as possible. A failed cooling module should only be removed
from the subsystem when you have a replacement module immediately available that can
be installed as soon as the failed cooling module has been removed.
CAUTION!
The latches at the back of the cooling module secure the cooling module into the enclosure. If
these latches are broken, the warranty on the cooling module will be void.
6.6.2
Replacing a Cooling Module
If one of the cooling modules fails, it must be replaced as soon as possible. The cooling modules are secured to the chassis with the two (2) black latches located on the rear surface of
the module itself. To replace the cooling module, please follow these steps:
CAUTION!
•
Although the cooling modules are fully redundant, it is not advisable to run the RAID subsystem with a single cooling module for an extended period of time. If the remaining cooling module fails, the system is at risk of sustaining irreparable damage.
•
1.
Keep a failed module in its enclosure bay until a replacement unit is in hand.
To remove the cooling module, pull both side latches toward the center of the cooling
module. Withdraw the cooling module from the subsystem by gently pulling on the silver
handle at the bottom of the module. (See Figure 6.17)

6.7
Installing the new Cooling Module
Replacing a Failed Hard Drive
Hard drives for the subsystem can be purchased separately. When purchasing the hard drives,
the following factors should be considered:
Capacity (MB/GB): Use drives with the same capacity. RAID arrays use a “least-commondenominator” approach. The maximum capacity of each drive used in the array is the maximum capacity of the smallest drive. Choose big drives with the same storage capacity.
Profile: The drive trays and bays of the system are designed for 3.5-inch wide x 1-inch-high
hard drives. It is highly recommended that you do not try to use drives of any other size.
Drive type: The RAID subsystem described in this manual can use SATA-I or SATA-II hard
drives. Please ensure that you purchase the correct hard drives.
CAUTION!
The hard drives and drive trays should only be installed into the subsystem after the subsystem has been mounted into a rack cabinet. If the hard drives are installed first, the subsystem will be too heavy to lift and the possible impact during installation may damage your
drives.
CAUTION!
•
Handle hard drives with extreme care. Hard drives are very delicate. Dropping a drive
onto a hard surface (even from a short distance) and hitting or touching the circuits on
the drives with your tools may cause damage to the drives.
•
•
F.01U.027.799 | V1 | 2006.05
Observe all ESD prevention methods when installing drives.
Only use screws supplied with the drive canisters. Longer screws may damage the drive.

Hard Drive Maintenance Overview
•
Hot-swappable drive trays: The drive trays are all hot-swappable. If a hard drive fails, it
can be replaced while the subsystem is still running.
•
Handles: If the failed hard drive is behind either the left or right front handle, unfold the
handles to open the front access to the drive trays. (See Figure 6.19)
Fig. 6.19
•
Open the Front Handles
Open flap: Once the flap on the drive tray has been opened, the drive tray must be
removed from the subsystem. Failure to remove the drive tray from the subsystem after
the flap has been opened may cause data errors.
•
Remove drives slowly: When removing a drive tray from the RAID subsystem, pull the
drive tray out only about one inch and then wait for at least 30 seconds for the hard drive
motor to spin down before taking it out completely. Any impact to the hard drive while
the drive motor is spinning can damage the drive.
•
Keep a replacement on hand: If a hard drive has failed, make sure you have a replacement
hard drive readily available before removing the failed drive from the subsystem. Do not
leave the drive tray slot open for an extended period of time or the normalized airflow will
be disrupted and subsystem components will overheat and may become permanently
damaged.
6.7.2
Replacing a Hard Drive
When a hard drives fails, it needs to be replaced. To replace a hard drive, please follow these
steps:
CAUTION!
The hard drive is fragile—always handle with extreme care. Do not drop the hard drive; always
be slow, gentle, and careful when setting down a hard drive. Only handle the hard drive by the
edges, and avoid touching any components or connectors.
1.
Identify the drive tray that contains the hard drive that needs to be replaced.
2.
Open the key-lock. To remove the drive tray from the enclosure, the key-lock must be
unlocked. (See Figure 6.20) To do this, turn the key-lock on the front of the drive tray
until the groove on its face is in a horizontal orientation.
