Safety Precautions
Safety Precautions
Read these instructions carefully before you install, operate, or transport the EonStor
DS RAID system and JBODs.
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).
5

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
8
Product Overview
This manual introduces 2U, 3U and 4U RAID/JBOD system that support 3Gbps,
6Gbps SAS or 3Gbps (SATA-II) and 6Gbps (SATA-III) drive interfaces. The 2U/ 3U/
4U enclosure is designed to utilize 3.5” hard drives. Drive capacity can be expanded
by attaching expansion hard drive enclosures (JBODs).
58
Model Naming Conventions
The naming rules for RAID and JBOD models are explained in the example below:
RAID: SxxF-Rxxxx S(A) + xx(B) + F(C) + R(D) + xxxx(F) + (N)
JBOD: SxxS-JxxxxR S(A) + xx(B) + S(C) + J(E) + xxxx(F) + R(D) + (N)
Designation Description
(A) Drive-side interface: S = SAS-2 / SATA-II / SATA-III
(B) Number of hard drive bays: 12/ 16/ 24
©
Host-side interface:
F= Fibre or hybrid Fibre/ iSCSI
E= iSCSI
S= SAS or hybrid SAS/ iSCSI
(D)
Number of controllers:
R= redundant (dual)
S= single and upgradeable to dual controller
G= single and NOT upgradeable to dual controller
(E) “J” stands for JBOD.
(F) Model number
N Indicates the system uses DC power supply units

Model Variations
Comprised of RAID and JBOD models, the RAID systems store hard drives and
control the entire storage system while JBOD systems connect to a master RAID
system and can expand storage capacities by adding more hard drives. All systems
are compatible with SAS-3 and SAS-6; SATA-II 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, please contact your system vendor
immediately.
The Cache Backup Module (CBM) is an optional feature in single controller systems.
62
RAID Controller and Interface
Each RAID 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. Because of a shorter discharge
time, BBU life expectancy is extended, and data is safely kept in flash regardless of
the traditional 72 hours limitation.
The embedded firmware features intelligent algorithms, such as power-saving
modes, variable fan speeds, and exiled drive handling, making this model a greener
choice.
63
JBOD 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 JBODs, connects to a
RAID system and serves as a building block of a scalable configuration.
In terms of supported protocols, the firmware supports communications with
enclosure devices, SAS/SATA disk drives and as RAID system featuring 6Gbps SAS
expansion ports.
In terms of physical connection, the SAS interface provides ease of cabling through
Mini-SAS connectors. With a backplane adapting SAS or SATA drives, the system
supports enterprise-class SAS, cost-effective SATA-II or SATA-III hard drives, and is
ideal for adding large capacity to a storage pool.
