2 Introduction

This manual covers the DVA-08K series of RAID subsystems.
With its basic hardware redundancy and the capability of fast I/O transfer, the 2U RAID SATA
subsystem is an ideal solution to meet the ever increasing demands for addition of storage
capacity. Despite its ease of use, the subsystem does not compromise data protection for
convenience. The subsystem’s embedded firmware offers the same protection and mainte­nance functionalities as those designed for an enterprise-level RAID solution. The subsystems
provide unprecedented configuration flexibility and allow for the customization of storage
subsystems to meet specific demands. It is a rigorous and durable subsystem that can be eas­ily configured and operated.
Fully featured RAID redundancy (which provides advanced data protection) ensures that the
complete range of RAID levels (RAID 0, 1(0+1), 3, 5, 10, 30 and 50) is supported by the con­troller head. A long list of sophisticated firmware functions (dedicated/global hot-spares, bat­tery protected disk cache, configurable reaction schemes against drive errors, remote and
real-time array monitoring, and more) further guarantees the overall availability of valuable
data.
IT managers using the RAID subsystems will be able to rapidly develop a comprehensive stor­age array. And the modular nature of the subsystem minimizes the maintenance effort to use
the RAID appliance.

2.1 Product Overview

The subsystem comes with two (2) SCSI-320 host channels interfaced through four (4) VHDCI
68-pin SCSI ports. The subsystem comes in a 2U-profile rack-mountable chassis which houses
a RAID controller module featuring complete RAID configuration and data protection function­ality. The subsystem’s operation is protected by redundant, hot-swappable power supplies
and cooling fan modules. Designed for a high level availability, all major components are hot­replaceable including its Li-ION battery and the RAID-protected disk drives.
The subsystem supports high-density array capacity by its eight drive bays for SATA-II inter­face disk drives. The subsystem facilitates large I/O transfer, over its dual PCI-X buses archi­tecture, and transmission of block I/Os over flexible caching and a dedicated XOR engine. The
subsystem is ideal for direct-attached data storage, backup, and retrieval. It combines the
capabilities and block-level performance of RAID storage with the reliable SCSI transfer tech­nologies.
Configured arrays are easily combined with multiple ID/LUNs that appear to the host ports,
turning massive capacity into manageable units for data-sharing in a heterogeneous environ­ment.
The RAID 2U-profile, SCSI-to-SATA RAID storage comes in two different models. The only dif­ference between the two models is the number of SATA-II drive bays.

SCSI Host Ports

Connectivity: The subsystem features a 320MB/s bandwidth from each of its SCSI host chan­nels. The dual-stack VHDCI connectors on the rear panel facilitate the connection to multiple
host computers and combining the storage capacities of multiple RAID subsystems. Its back­ward compatibility with older SCSI protocols requires minimum investment for upgrading
equipment. Storage volumes are associated with SCSI ID/LUNs on the host channels. The
subsystem firmware provides flexible configurations of storage volumes which include, logical
drives in supported RAID 0, 1 (0+1), 3, and 5 levels, logical volumes that consist of one or
more logical drives, and the logical partitions of the previously mentioned configurations.
These volumes then appear as SCSI targets over the host links.

Bosch Security Systems F.01U.027.797 | V2 | 2008.08

i

Channels: The SCSI ID/LUN mapping method enables users to associate a storage volume
with multiple IDs or LUNs on the host channels. The mapping method can easily cope with
host-side configurations such as clustered servers or high availability path redundancy. On the
drive side, all of the eight (8) SATA-II drives are connected each through a dedicated SATA
channel. Each drive channel is routed to an enclosure drive tray that is equipped with a stan­dard SATA connector with of hot-swap capability. The methods used for assembling physical
drives, fault management, and status monitoring are identical to that used with Bosch’s long
line of RAID storage enclosures.

Active Components

The subsystem comes with:

• A single RAID controller module

• Two redundant, hot-swappable cooling modules

• Dual redundant, hot-swappable, load-sharing power supplies

• A module slot for a Li-ION battery module.

• The front section of the enclosure houses eight (8) hot-swap drive bays for SATA-II or

backward compatible with SATA-I hard disk drives.

The subsystem is shown below:

Fig. 2.1 8-bay SATA RAID Subsystem

NOTICE!

i

• BBU module: A BBU provides the protective implementation to cached data; and, unless

deselected when purchasing the subsystems, is installed into the module slot located at
the upper left corner of the controller module.

• Cooling fan module: The redundant cooling fan module is used to ventilate the subsystem

and to reduce the temperature within the subsystem.

NOTICE!

Each of the power supplies on the sides of the enclosure houses one cooling fan module in a
removeable canister. When a power supply is removed, the cooling module is also removed.
Therefore, replace the power supply unit as soon as possible whenever it becomes necessary.
Cooling fan modules can be independently removed from the chassis without affecting PSU
operation.

2.2.6 Backplane Board

An integrated backplane board separates the front and rear sections of the subsystem. The
PCB board provides traces for logic level signal traces and low voltage power paths. It con­tains no user-serviceable components.

2.3 Subsystem Components

All the active components on the subsystem can be accessed through either the front or rear
panel. The modular design of the active components facilitates their easy installation and
removal. Hot-swap mechanisms are incorporated to eliminate power surges and signal
glitches that might occur while removing or installing these modules.

2.3.1 LCD Panel

Fig. 2.6 Opening the Front Handle

The LCD panel shown in Figure 2.6 consists of a 16 characters x 2 rows LCD screen with push
buttons, a mute button, and LED status indicators. The LCD front panel provides full access to
all array configurations and monitoring. After powering up the subsystem, the initial screen
will show the subsystem model name. A different name can be manually assigned to the sub­system or different drive arrays. This will enable easier identification in a topology consisting
of numerous arrays.

Fig. 2.7 Front Panel Retention Latch

To access drive bays in the left- or right-hand side column, first flip the retention latches (see
Figure 2.7) on the enclosure front handles, and then swing the handles to the left- and right­hand sides. To close the handles (see Figure 2.8), swing the handles toward the system; gen­tly press the handles until a click is heard. The latches will keep the handles in place.

Fig. 2.8 Closing the Front Handles

2.3.2 Drive Trays

The subsystem comes with 8 drive trays (see Figure 2.9) designed to accommodate separately
purchased standard 1-inch pitch, 3.5-inch disk drives. The drive bays are accessed from the
enclosure front. Two LED’s on the front of the tray are used to indicate the drive status. A key­lock on each drive tray secures the hard drive in place, while an easily accessible release but­ton ensures fast and efficient drive hot-swapping.

Fig. 2.9 Drive Tray Front View

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
subsystem. If the drive bay superstructure is deformed or altered, the drive trays may not fit
into the drive bay.

2.3.3 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 necessary support interfaces. The controller module
contains no user-serviceable components. Except when replacing a faulty unit or 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 replace the memory module or to install the memory module. The RAID controller is
built of sensitive components and unnecessary tampering can damage the controller.

Controller Module Interfaces

The subsystems provide external interfaces to host computers and management station(s)
through the RAID controller’s rear-side faceplate as shown in Figure 2.10.

Fig. 2.10 Controller Module Faceplate

• Host Ports

SCSI-320 Host Ports: Two SCSI-320 host channels connect the subsystem to the host
computers equipped with SCSI-320 compatible adapters through the dual-stack VHDCI
connectors. The dual-stack connectors facilitate cascade connections for configurations
such as host clustering or cascading with another RAID subsystem.

i

NOTICE!

This subsystems come with preset configurations for channel mode and channel ID settings,
and should be sufficient for most applications.

• Ethernet Port

All controller modules on the subsystems come with a single 10/100BasedT RJ-45 Ether­net port. The Ethernet port is used for local or remote management through the network
using the Bosch RAIDWatch GUI manager or Telnet protocol.

• COM Port

All controller modules come with one RS-232C (audio jack) serial port. The serial port is
used for local access to the system-embedded configuration utility over the included
serial port cable.

DIMM Module

The controller module comes with a preinstalled 256MB capacity or above DDR RAM DIMM
module and can support a larger capacity up to 2GB. The DIMM module is mounted in an eas­ily accessible location on the controller board. However, when the DIMM module is being
changed, the controller module must be removed from the subsystem chassis.

2.3.4 Battery Backup Unit

The Li-ION battery backup unit (BBU) module sustains cache memory for days after a power
failure. It is installed on the upper left corner of the controller module in the rear of subsystem
chassis. Please refer to Section 3 Hardware Installation for installation details.

Fig. 2.11 BBU Module

In accordance with international transportation regulations, the BBU module is only charged
to between 35% and 45% of its total capacity when shipped. Therefore, when powering on the
subsystem for the first time the BBU will begin to charge its batteries to their 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 (its LED is still flashing), there is a problem
with the BBU module 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 controller
module will flash.
You can check the status of the battery’s charge via Bosch RAIDWatch Manager or the firm­ware utility screen.

2.3.5 Power Supply Units

The SATA-based RAID subsystems are equipped with two (2) redundant, hot-swappable, 2U,
350W power supply unit (PSUs) modules. The PSU is permanently mounted into a 2U high
(dual-level) bracket especially designed to house both the PSU and a cooling module mounted
underneath. PSUs can be found on either side of the controller module.
Each PSU comes with a single power socket for power cord plug-in and a single power switch
for you to turn the PSU on and off. Each PSU also comes with two embedded cooling fans to
provide sufficient airflow to keep the PSU cool. A single LED is used to indicate the PSU sta­tus. A handle at the back of the PSU has been especially designed to enable you to remove the
PSU from the subsystem while the system is still online. This should only be done if the PSU
has failed and needs to be replaced.

NOTICE!

Hot-swapping the PSU also removes the cooling module at the lower slot.
A retention screw at the upper right corner of the PSU module is used to secure the PSU to
the enclosure. If the PSU needs to be removed, the retention screw must be removed first.
When installing a new PSU module, make sure that the retention screw has been firmly
secured.

Fig. 2.12 PSU Module

2.3.6 Cooling Fan Modules

The SATA-based RAID subsystem is equipped with two 1U single-fan, redundant, hot-swappa­ble cooling modules shown in Figure 2.13. One 9.7cm fan is housed in each cooling module.
These modules have been designed to generate a cooling flow from the front to the rear of the
subsystem to extract the heat generated by the SATA hard drives. Two of the cooling fan mod­ules are installed directly beneath the PSUs.

Fig. 2.13 Top View of a Cooling Fan Module

Advanced Fault-Preventative Operation

The cooling fan modules support dual-speed operation modes that help to protect the subsys­tem in the event of component failure or extreme working condition.

Intelligent Dual Speed Operation

The cooling fans operate with two rotation speeds. Under normal operating conditions, the
cooling fans run at the low speed, which is sufficient for maintaining efficient airflow across
components. Under the following conditions, cooling fans raise their rotation speed to
increase the airflow:

1. Component Failure: if another cooling fan module, a PSU, or a temperature sensor fails,
the remaining cooling fan(s) automatically raises its rotation speed.

2. Elevated Temperature: if the temperature breaches the upper threshold set for any of the
interior temperature sensors, the cooling fans automatically raises its rotation speed.

3. During the subsystem initialization stage, the cooling fans operate at the high speed and
return to lower speed once the initialization process is completed and no erroneous con­dition is detected.

NOTICE!

There are two values set for the upper temperature thresholds. One is set for event notifica­tion and the other triggering higher fan rotation speed. The preset value for event notification
can be changed using the firmware-embedded configuration utility, while the fan speed trig­ger is not a user’s option.

RAID Subsystem DVA-08K | Installation Manual Introduction | en 17

2.4 Subsystem Monitoring

The SATA-based RAID subsystem comes with a number of different monitoring methods that
provide you with continual updates on the status of the system and individual components.
The following monitoring features are included in the subsystem.

2.4.1 I2C Bus

The following subsystem elements are interfaced to the RAID controller over a non-user-ser-

viceable I2C bus:

• Cooling fan modules

• PSUs

• Temperature sensors

2.4.2 LED Indicators

The following active components come with LEDs to indicate the status of the individual com­ponents:

• RAID controller

• LCD panel

• Cooling fan module

• PSU module

• BBU module

• Drive trays

2.4.3 Firmware and Bosch RAIDWatch GUI

Firmware: The firmware is pre-installed software that is used to configure the subsystem. The
firmware can be accessed either through the LCD keypad panel or a terminal emulation pro­gram running on a management computer that is connected to the subsystem’s serial port.
Bosch RAIDWatch: Bosch RAIDWatch is a premier Web-based graphical user interface (GUI)
that can be installed on a remote computer and is used to access the array through LAN or the
Internet. The manager communicates with the array via the connection of the existing host
interface or Ethernet link to the RJ-45 LAN port.

2.4.4 Audible Alarms

The subsystems come with audible alarms that are triggered when certain active components
fail or when certain (controller or subsystem) thresholds are exceeded. If you hear hastily
repeated beep tones from the subsystems it is imperative that you immediately determine and
rectify the problem.
Event notification messages indicate the completion of or the condition when proceeding with
array configuration tasks and are always accompanied by two or three successive and pro­longed beeps.

CAUTION!

Failing to respond when a critical alarm is heard can lead to permanent damage of the subsys­tem. When an audible alarm is heard, rectify the problem as soon as possible.

18 en | Introduction RAID Subsystem DVA-08K | Installation Manual

2.5 Hot-Swappable Components

2.5.1 Hot-Swap Capabilities

The 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.

2.5.2 Components

The following components are all hot-swappable:

• Power supply units (PSUs)

• Cooling fan modules

• Hard drives

• BBU module

2.5.3 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.

3 Hardware Installation

This chapter gives detailed instructions on how to install the subsystem. When installing the
subsystem, it is necessary to mount the chassis into a rack or cabinet and to install hard
drives and drive trays. Installation into a rack or cabinet should occur before the hard drives or
drive trays are installed into the subsystem. Please confirm that you received all of the compo­nents listed on the Unpacking List that came with the subsystem before proceeding with the
installation process.

CAUTION!

Please note that the installation instructions described in this chapter should be carefully fol­lowed to prevent any difficulties and damages to your system.

3.1 Installation Prerequisites

• Static free installation environment: The subsystems must be installed in a static-free

environment to minimize the possibility of electrostatic discharge (ESD) damage. (See
Section 1 Warnings and Certifications).

• Component check: Before installing the subsystems, you should first check to see that

you have received all the required components. If any items appear damaged, contact
your vendor for a replacement.

• Hard drives: Hard drives must be purchased separately prior to the subsystem installa-

tion.

• Cabling:

– The subsystems requires an external VHDCI-to-VHDCI SCSI round cable to connect

the subsystem to a host computer.

– One (1) audio-jack-to-DB9 cable is provided to facilitate the connection of the COM1

port for local terminal emulation access to the array.
– Two (2) power cords are provided for the power connections to the power sources.
– The RJ-45 Ethernet cable for network management connection is a user-supplied

item.

• Memory module: If you wish to change the pre-installed memory module, a separately

purchased module must be installed. Please contact your vendor for a different memory
module or consult the list of compatible modules.

• Rack installation: The enclosure chassis can be installed into a rack cabinet using self-

purchased mounting rails. A printed copy of installation guide is provided with the slide
rails package.

3.2 Safety Precautions

3.2.1 Precautions and Instructions

• Be sure the correct power range (100-120 or 220-240VAC) is supplied by your rack cabi-

net, UPS device, or power outlet.

• 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 severely 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.

• An enclosure without disk drives can weigh over 25 kilograms. Two (2) people are

required to install or relocate the subsystem. To avoid damage to disk drives, drives
should be removed from the enclosure before moving the subsystem.

• Handle the system modules by the retention screws, extraction levers, or the modules

metal frames/faceplates only. Avoid touching the PCB boards, connector pins, and sol­dered surfaces.

• 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.

• None of the covers or replaceable modules should be removed in order to maintain com-

pliance with safety, emission, or thermal requirements.

• Always secure every enclosure module by its retaining screws or make sure it is held in

place by its latches.

• Always make sure the subsystem has a safe electrical earth connection via power cords

or chassis ground by the rack cabinet.

• 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.

• 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.

• If it is necessary to transport the subsystem, repackage all disk drives separately. If using

the original package material, all other modules can stay within the enclosure.

3.2.2 Static-Free Installation

The subsystem contains static-sensitive electronic components that can be damaged by
improper handling and electrostatic discharge (ESD). To prevent ESD damage to any of the
components, follow these precautions before touching or handling them:

• Discharge the static electricity from your body by wearing an anti-static wristband or by

touching a grounded metal surface.

• Avoid carpets, plastic, vinyl, and styrofoam in your work area.

• Handle all components by holding their edges or metal frame. Avoid touching PCB boards

and connector pins.

3.2.3 BBU Warnings and Precautions

The BBU module sustains cache memory in the event of a power failure or in the unlikely event
if both PSUs have failed. Having the protection to cached data by a BBU is highly recom­mended. The BBU provides additional data security and helps minimize the chance of data
loss during power outage.

• Replace the BBU once it shows symptoms failing to hold the charge. Although the life

expectancy of a BBU is determined by the times it has been charged or discharged, a BBU
can approximately last for one year. If the battery recharge time is obviously longer than
the suggested 12 hours, or if the fault LED is lit, replace the battery.

• Install or replace the BBU module only with a BBU module supplied by your subsystem

vendor. Use of battery cells provided by another source will void our warranty.

• Always dispose of discharged or used batteries in an ecologically responsible manner.

Dispose used BBUs at authorized battery disposal sites only.

• Do not use nor leave the BBU near a heat source or direct sunlight. 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, over-

heat, 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 leaks, 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.
