Safety Precautions
Read these instructions carefully before you install, operate, or transport the EonStor
DS storage system and expansion enclosures.
Installation and Operation
Install the rack cabinet and the associated equipment at a site where the ambient
temperature (special room cooling equipment may be required) stays lower than:
a. 35C ~ if your system have a BBU (all dual controller systems come with
BBU by default)
b. 40C ~ if your system does not have a BBU
Install the power source socket outlet near the enclosure where it is easily
accessible and ground the rack cabinet.
Secure airflow clearance inside and around the rack cabinet.
- Secure an 18 to 20cm clearance on the rear side.
- Do not cover the enclosure openings.
- Route the cables inside the rack cabinet.
- Do not leave drive bays empty as it will affect airflow efficiency.
Secure each enclosure module using its retaining screws.
Place power cords and other cables away from foot traffic. Do not place items on
top of power cords and make sure they do not rest against data cables.
Install all modules to the enclosure before powering-on systems.
Ensure that the correct power range is being used before powering-on.
DO NOT remove covers or replaceable modules if they are not faulty.
If the system is not going to be used for a long period of time, disconnect it from the
power mains to avoid transient over-voltage.
For power source redundancy, please make sure that the two PSUs are plugged
into two different power sources (ie. different circuit breakers).

Service and Maintenance
Service and Maintenance
Keep the faulty module in place until you have a replacement unit; an empty
module greatly affects the airflow efficiency within the enclosure.
During service operation, place the enclosure on soft and clean surface to prevent
exterior damage. Do not place tools or other items on top.
When transporting the enclosure, repackage all disk drives separately in the
original package foam blocks. Replaceable modules can stay in the enclosure if
you are using the original package; if not, repackage them separately as well.
Disconnect the power cords before servicing or cleaning the enclosure.
Use a slightly moistened paper sheet or cloth for cleaning. Avoid using liquid or
sprayed detergent.
When replacing components, insert them as gently as possible while assuring full
engagement. Vibration and shock can easily damage hard drives.
Only qualified service personnel should open the enclosure.
Contact service personnel if any of the following situations occurs:
- The power cord or plug is damaged.
- The enclosure has been exposed to moisture.
- The system has not been working properly.
- The enclosure was dropped against a hard surface.
- The enclosure shows obvious signs of breakage.
To move the enclosure, more than one person might be necessary due to its weight.
Drives should be removed from the enclosure beforehand.
Important Notice
The use of Infortrend certified components is strongly recommended to ensure
compatibility, quality and normal operation with your Infortrend products. Please
contact your distributor for a list of Infortrend certified components (eg. SFP, SFP+,
HBA card, iSCSI cable, FC cable, memory module, etc.).

ESD Precautions
ESD Precautions
Handle the modules by their retention screws, ejector levers, or the module’s metal
frame/faceplate only. Avoid touching the PCB boards or connector pins.
Use a grounded wrist strap and an anti-static work pad to discharge static electricity
when installing or operating the enclosure.
Avoid dust, debris, carpets, plastic, vinyl, and styrofoam in your work area.
Do not remove any module or component from its anti-static bag before installation
takes place.
Drives must not be stacked on top of each other without their protective drive trays.
Even when drives are fixed in the drive trays, contacting the exposed PCB or
rear-side interface may damage the drives.

Introduction
Product Overview
This manual introduces EonStor DS 1000 Gen2 systems that support 6Gbps,
12Gbps SAS or 6Gbps (SATA-III) drive interfaces. The 2U / 3U / 4U enclosure is
designed to utilize 2.5”or 3.5” hard drives. Drive capacity can be expanded by
attaching hard drive expansion enclosures.
Model Naming Conventions
The naming rules for storage systems and expansion enclosure models are
explained in the example below:
DS1024R2B DS(A) + 10(B) + 24(C) + R(D) + 2(E) + L(F) + B(G)

Model Variations
Comprised of storage system and expansion enclosure models, the storage systems
store hard drives and control the entire storage system while expansion enclosures
connect to a master storage system and can expand storage capacities by adding more
hard drives. All systems are compatible with SAS-3 and SATA-III hard drives. However
hard drive limitation(s) may vary model to model.

Major Components
NOTE
Upon receiving your system, check the package contents against the included
Unpacking List. If module(s) are missing, contact your system vendor immediately.
The Cache Backup Module (CBM) is an optional feature in single controller systems.
Controller and Interface
Each controller comes with a pre-installed DIMM module.
The traditional battery backup is replaced by an innovative Cache Backup Module
methodology (CBM) which consists of a battery backup unit (BBU) and flash backup
module (FBM). Cached data is quickly distributed to a flash backup module with the
support of a BBU in the event of a power outage. With a super capacitor and flash
backup module combination cached data will be quickly distributed to a flash backup
module for permanent storage in the event of a power outage. The advantage of a
super capacitor is its very fast charging time. The super capacitor is charged within a
few minutes and available to distribute power to the controller. So the cached data
can be saved immediately and permanently in flash backup module (FBM).
The embedded firmware features intelligent algorithms, such as power-saving
modes, variable fan speeds and exiled drive handling.
Expansion Enclosure Controller and Interface
The enclosure is managed by expander controllers that distribute data flow to
individual disk drives and report operating status through a proprietary enclosure
service via in-band protocols. The enclosure, along with other expansion enclosures,
connects to a storage system and serves as a building block of a scalable
configuration.
Expansion enclosures feature SAS interfaces that provide ease of cabling Mini-SAS
HD connectors. With a backplane adapting SAS connectors, the system is ideal for
adding large storage capacities to a storage pool.

16
Power Supply Unit with Built-in Cooling Module
Two cooling modules built into the power supply unit (PSU) protect the system from
overheating, and two hot-swappable PSUs provide constant power to the system.
The modular nature of the system and the easy accessibility to all major components
ensure ease of maintenance.

17
The Rear Panel
Dual Controller Models
Dual controller systems are indicated by an “R”in their model number (please refer
to Model Naming Conventions). Controller A is located on top and controller B at the
bottom for dual controller models. In dual controller configuration, if one controller
fails, the second controller module will take over in a manner that is transparent to
application servers.
The top controller (Controller A) is the primary controller. The bottom controller
(Controller B) is the secondary (= redundant) controller which is idle during normal
operation and takes over the management role when Controller A cannot function
properly due to hardware error, controller module removal, etc.
If the failed Controller A restarts or a replacement is installed, Controller A will
temporarily assume the role of the secondary controller.
When the storage system is rebooted, all system configurations will revert back to
the default state and Controller B returns the primary role back to Controller A.

18
Single-Controller Models
Single-controller models are designated by a “G”in their model number. The second
controller slot is filled with a dummy cage (D).
Connection between Storage Systems and Expansion Enclosures
The following rule applies when connecting storage systems and expansion
enclosure(s):
Dual-controller storage system connects to dual-controller expansion
enclosure.
Single-controller storage system connects to single-controller
expansion enclosure.

19
Chassis
The storage system chassis is a rugged storage chassis divided into front and rear
sections. The chassis is designed to be installed into a rack or cabinet.
Front Panel
Ex. 1: 3U / 16-bay
Ex. 2: 2U / 24-bay, SFF
Hard drive trays (1): Each drive tray is hot-swappable and holds a 2.5 /
3.5-inch hard drive.
LED Panel (2): It contains Service / Power / Cooling Fan / Thermal /

Mute button / service LED (3): The mute button is to mute an alarm when
sound or to indicate that the system requires service.
Rotary ID switch in expansion enclosure systems (4): The rotary ID
switch is for users to set a unique ID to each expansion enclosure when
connected in a multi-array environment.

20
Handles (5): There are handles on both sides of the enclosure for users to
pull / push the enclosure out and into the cabinet when the enclosure is
installed on a slide rail rackmount system.
Rackmount holes (6): There are two rackmount holes (one on each side
of the enclosure) for users to secure the enclosure onto the cabinet.
Hard drive status LED (7): There is a set of hard drive status LEDs on
each hard drive tray or right hand side or below of it to indicate operation
status.
