Safety Precautions
Precautions and Instructions
 Prior to powering on the subsystem, ensure that the correct power
range is being used.
 If it is necessary to transport the subsystem, repackage all disk drives
separately. Shipping the subsystem with installed hard drives will
damage the backplane connectors.
 The EonStor subsystem comes with sixteen (16) drive bays. Leaving
any of these drive bays empty will seriously affect the efficiency of
the airflow within the enclosure, and will consequently lead to the
system overheating, which can cause irreparable damage.
 If a module fails, leave it in place until you have a replacement unit
and you are ready to replace it.
 Airflow Consideration: The subsystem requires an airflow clearance,
especially at the front and rear.
 Handle subsystem modules using the retention screws, ejection
levers, and the metal frames/faceplates. Avoid touching PCB boards
and connector pins.
 To comply with safety, emission, or thermal requirements, none of
the covers or replaceable modules should be removed. Make sure that
during operation, all enclosure modules and covers are securely in
place.
 Be sure that the rack cabinet into which the subsystem chassis will be
installed provides sufficient ventilation channels and airflow
circulation around the subsystem.
 Provide a soft, clean surface to place your subsystem on before
working on it. Servicing on a rough surface may damage the exterior
of the chassis.
 Dual redundant controller models come with two controller modules
that must be installed into the subsystem. Single controller modules

EonStor F16F-R/S4031-6/4 Installation and Hardware Reference Manual
x
come with a single controller module and a metal sheet is placed over
the lower controller bay at the rear of the subsystem. Since single
controller modules cannot be upgraded, this metal sheet should
NEVER be removed.
ESD Precautions
Observe all conventional anti-ESD methods while handling system
modules. The use of a grounded wrist strap and an anti-static work pad are
recommended. Avoid dust and debris in your work area.

Introduction
1.1 Product Overview
1.1.1 Product Introduction
This hardware manual briefly introduces the EonStor Fibre-to-Fibre RAID
subsystem. The F16F series comes with either six (6) or four (4) 4Gbps
Fibre channels on each RAID controller and supports sixteen (16) hot-
swappable Fibre hard drives in a 3U chassis. The series is built around the
5th-generation ASIC400 as the hardware RAID6 engine with a pre-installed
512MB cache memory or
another module of up to
2GB in size. The 4Gb/s
Fibre Channels are
interfaced through twelve
(12) SFP ports to facilitate
flexible, fault-tolerant host
or expansion links.
More significant is the loop switch architecture that eliminates LIP
overheads and improves FC loop performance. Six (6) embedded SATA
channels are used for cross-controller communications providing
exceptional bandwidth for synchronized cache operation.
The F16F series comes with redundant- or single-controller configurations
and the most advanced fault-tolerance features in the industry. Host and
drive channels are routed through separate I/O boards. Channels routed
through an I/O board are each from a different I/O processor to reduce the
chance of down time by component failure.
Dual-redundant, hot-swappable cooling and power supply modules protect
the subsystem from single point of failure. The modular nature of the
subsystem and the easy accessibility to all major components ensure the
ease of the subsystem maintenance.

1.1.3.1 Chassis Overview
The F16F-R/S4031 RAID storage subsystem is housed in a compact steel,
3U chassis divided into front and rear sections, which are respectively
accessed through the front and rear panels. An interior aluminum
framework enables evenly dispersed heat and efficient dissipation.
Infortrend’s 3U rackmount brackets are available as separately-purchased
accessories. Please see Figure 1-3 and Figure 1-4 for the components’
locations in the subsystem and read the following sections for details about
components and modules.

1-4 Product Overview

Chapter 1: Introduction
1.1.3.2 Physical Dimensions
The F16F subsystem comes in an enhanced 3U chassis with the following
dimensions:
 With handles: 482.6mm x 131mm x 504.3mm (19 x 5.2 x 19.9
inches) (width x height x depth)
 Without handles: 445mm x 130mm x 488.2mm (17.5 x 5.1 x 19.2
inches) (width x height x depth)
1.1.3.3 Channels
The F16F subsystem comes with either six (6) or four (4) 4Gbps Fibre
channels. Each channel is routed through two (2) SFP ports to provide a
total of up to twelve (12) FC ports. (See Figure 1-5) Shown below are
details of these I/O ports:
Table 1-3 F16F Model Variations
Model CH0 & CH1 CH2 & CH3 CH4 & CH5
F16F-R4031-6 4 x SFP (host) 4 x SFP (drive
extension) 4 x SFP (host or drive expansion)
F16F-S4031-6 4 x SFP (host) 4 x SFP (drive
extension) 4 x SFP (host or drive expansion)
F16F-R4031-4 4 x SFP (host) 4 x SFP (drive
extension) N/A
F16F-S4031-4 4 x SFP (host) 4 x SFP (drive
extension) N/A
 CH0 and CH1 are defaulted as host port modules. Each channel is
interfaced through two (2) SFP host ports on each controller.
 Disk drives within the F16F are linked across a Fibre Channel dual-
loop configuration controlled by a high efficiency loop switch. CH2
and CH3 can be extended to Fibre Channel expansion SBODs.
 CH4 and CH5 can be manually configured either as host or drive
channels. You can change the channel mode of CH4 and CH5 via
firmware configuration utilities. Please see Chapter 4 for details.

controller B port definitions only apply in redundant-controller
configurations when their onboard hub is disabled.
Figure 1-9: A Ports and B Ports in a Dual-controller Configuration
A simplified view of onboard hub is shown below. LD is short for “Logical
Drive.”
Figure 1-10: Onboard Hub and Access Routes
If the onboard hub is enabled, the twin ports will be “hubbed” together.
Any of the twin ports provides equal access to both of the RAID
controllers (as shown in the lower half of the above diagram).
2. The A port and B port definitions only apply in dual-controller models:
F16F-R4031-6 and F16F-R4031-4.
3. CH2 and CH3 are the extension of the drive-side dual loop. There are
no controller-specific port definitions with CH2 and CH3 I/O ports.
The dual loop is physically interfaced with dual-ported Fibre drives and
both of the RAID controllers.
