INTRODUCTION
1. Introduction
This section presents a brief overview of the 12/16 bays external Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem.
1.1 Overview
SAS 2.0 builds on parallel SCSI by providing higher performance,
improving data availability, and simplifying system design. The SAS
2.0 interface supports both 6Gb/s SAS disk drives for data-intensive applications and 6Gb/s Serial ATA (SATA) drives for low-cost
bulk storage of reference data. The Fibre/SAS/iSCSI to 6Gb/s SAS
RAID controllers attach directly to SATA/SAS midplanes with 3 x
Z-PACK HM-Zd high speed connectors or increase capacity using
one additional SFF-8088 external connector. When used with SAS
expanders, the controller can provide up to (122) devices through
one or more SAS JBODs, making it an ideal solution for enterpriseclass storage applications that called for maximum configuration
flexibility.
The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem provides three
kinds of host interface link to the host board on the server system. This subsystem utilizes the same RAID kernel that has been
field-proven in existing internal/external SATA/SAS RAID controller
products, allowing to bring stable and reliable SAS RAID external
subsystem.
The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem provides a
2U/3U rack-mounted external storage chassis capable of accommodating up to 12/16 6.0-Gb/s, Serial-Attached SCSI (SAS) drives or
6.0-Gb/s Serial ATA (SATA) drives. The redundant controller model
provides fault-tolerant links across separate host interface, while
the single controller model provides a single, straight-through data
path.
Unparalleled Performance
The high speed host interfaces make Fibre/SAS/iSCSI to 6Gb/s
SAS RAID subsystem well suited for professionals who need large
capacity and exceptional performance with connectivity. The Fibre/
6
INTRODUCTION
SAS/iSCSI to 6Gb/s SAS RAID subsystem incorporates onboard
high performance 800MHz RAID-on-Chip storage processor and
DDR2-800 SDRAM memory to deliver true hardware RAID. The
subsystem each includes one DIMM socket with default 1GB of ECC
DDR2-800 register SDRAM with optional battery backup module,
upgrade to 4GB using x8 or x16 devices. The test result is against
overall performance compared to other external SAS RAID subsystems. Applications demand for higher computing power, networking
bandwidth and support for virtualization applications are driving
RAID subsystem for improved architecture internal bus interface
and RAID performance. The powerful new ROC processors integrated 16 x 6Gb/s SAS ports on chip delivers high performance for
NAS, server RAID solutions, supercomputing, near-line backup,
security systems, streaming and cloud computing applications.
Unsurpassed Data Availability
Designed and leveraged with Areca’s existing high performance
solution, this controller delivers high-capacity at the best of cost/
performance value. It supports the hardware RAID 6 engine to allow two HDDs failures without impact the existing data and performance. Its high data availability and protection derives from the
many advanced RAID features.
The Fibre/SAS/iSCSI to SAS RAID subsystems allows easy scalability from JBOD to RAID. It can be configured to RAID levels 0,
1, 1E, 3, 5, 6, 10, 30, 50, 60, Single Disk or JBOD. With innovative
new RAID-on-Chip 6Gb/s SAS feature and support for SATA, SAS
and SSDs, the Fibre/SAS/iSCSI to SAS RAID subsystems provides
small- to mid-sized enterprises with superior levels of RAID performance and scalability for external storage. Using cost-effective
SATA disk drive and completely integrated high-performance and
data-protection capabilities, it can meet the performance and features of a midrange storage product at an entry-level price.
Easy RAID Management
Configuration and monitoring can be managed either through the
LCD control panel, RS232 port or Ethernet port. The firmware also
contains an embedded terminal emulation via the RS-232 port.
The firmware-embedded web browser-based RAID manager allows
7
INTRODUCTION
local or remote to access it from any standard internet browser via
a 1Gb/s LAN port. The firmware contains SMTP manager monitors
all system events and user can select either single or multiple user
notifications to be sent via "Plain English" e-mails. The firmwareembedded SNMP agent allows remote to monitor events via LAN
with no SNMP agent required. The controller also supports API
library for customer to write its own monitor utility.
The controller also supports API library for customer to write its
own monitor utility. The Single Admin Portal (SAP) monitor utility
can support one application to manage multiple RAID units in
the network. The Disk Stress Test (DST) utility kicks out disks
meeting marginal spec before the RAID unit is actually put on-line
for real business. The hardware monitor can monitor subsystem
environment and show the warning message.

1.3.2.6 Power Supply/Cooling Fan LED
The enclosure supports two separate power modules. Each of
them contains an integrated power supply and two cooling fans.
The LEDs on the JBOD enclosure’s power supplies indicate
status of the power supply: one for AC_OK (green) and other
FAULT(red). The following figure is shown LEDs on the power
supply module.
13
INTRODUCTION
The following table describes the power LEDs status.
Power LED Status
Indication
AC_OK (Green LED)
The AC_OK LED indicates that the AC line is present and
above the minimum AC input voltage threshold
FAULT (Red LED)
The FAULT LED is driven by the microprocessor and will
indicate that a power supply fault has occurred.
The power supply cooling shall be provided by the internal tandem
fans, powered by the common 12V rail voltage. Fan speed is controlled by PWM input signal. And the power supply firmware shall
determine the fan RPM required to provide forced air cooling using
data from a thermal sensor in the power supply that reflects the
output loading.
The cooling fans included on the power supply run on separate control circuits from the power supply. Therefore, if one power supply
fails, the failed power’s fan continues to work on the power supplied from the other good power supply.
Note:
A power supply/cooling fan module can be removed from a
powered-on enclosure; however, the expander controller may
automatically shut down the enclosure if overheating occurs.
1.4 SAS RAID Subsystem Alarm
An audible alarm is activated if any of the fault conditions occur,
such as Voltage, Temperature, Fan, Power Supply or from SES2.
The “Alert Beeper Setting” function on the RAID System Function
is used to disable or enable the RAID subsystem alarm tone
generator. The “Mute The Alert Beeper” function on the "RAID
System Function" is used to control the Fibre/SAS/iSCSI to 6Gb/s
SAS RAID subsystem beeper. It turns the beeper off temporarily.
The beeper will still activate on the next event.
14
INTRODUCTION
Note:
It is rare for both Fibre/SAS/iSCSI to 6Gb/s SAS RAID
subsystem to fail simultaneously. However, if this occurs, the
RAID subsystem can not issue critical or non-critical event
alarms for any subsystem component.
1.5 Expansion Connection
The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem is a device
that contains one expander port. Expander port may support being attached to SAS initiator ports, SAS and/or SATA target ports,
and to other expander ports. The Fibre/SAS/iSCSI to 6Gb/s SAS
RAID subsystem can connect up to 7 expander enclosures to the
host system. The maximum drive no. is 122 through this RAID
subsystem with 7 expander enclosures. Enclosures installed with
SAS disks or SATA disks can be included in the same dasiy-chain.
The following figure shows how to connect the external Mini SAS
cable from the Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem
to the external SAS JBOD enclosure. Daisy-chains longer than
the limitation of subsystems are not supported even if it may be
workable.

compatible terminal or a PC running a VT-100 terminal
emulation program. You can attach a serial (Character-Based)
terminal or server com port to the SAS RAID subsystem for
access to the text-based setup menu. There are two multiple
function on those RJ11. The J3 jumper is on the controller
board used to define the RS 232 port connectors (VT-100 for
expander/Debug and VT-100 for controller) function.

• LAN Port Connection
The SAS RAID subsystem has embedded the TCP/IP & web
browser-based RAID manager in the firmware(method 3).
User can remote manage the SAS RAID subsystem without
adding any user specific software (platform independent) via
standard web browsers directly connected to the 10/100/1000
Ethernet RJ45 LAN port. Connect Ethernet port of the SAS RAID
subsystem using the included Ethernet cable and then to a LAN
port or LAN switch.

HARDWARE INSTALLATION
2.6.3 Power Up the RAID Subsystem
There is one main power on/off switch located on the rear side of
the RAID subsystem. This on/off power switch is used to apply or
remove power from the power supply to the RAID subsystem.
Turning off subsystem power with this switch removes the main
power but keeps standby power supplied to the RAID subsystem.
Therefore, you must unplug the power cord before subsystem
servicing.
The cooling fan included on the power supply run on separate
control circuits from the power supply. Therefore, if one power
supply fails, the failed power’s fan continues to work on the power
supplied from the other good power supply.
The installation is complete. You can use your SAS RAID subsystem.
Note:
A power supply/cooling fan module can be removed from a
powered-on subsystem; however, the subsystem should shut
down if overheating occurs.
2.7 Configuring RAID Subsystems
There are often multiple ways to accomplish the same configuration
and maintenance tasks for your SAS RAID subsystem. The SAS
RAID subsystem is normally delivered with LCD preinstalled. Your
SAS RAID subsystem can be configured by using the LCD with
keypad, a serial device (terminal emulation) or LAN port. Turn
to the relative section of RAID configuration in the user manual
for information about detail configuring RAID arrays. The user
manual is included on the shipping CD that came with your RAID
subsystem.
32
HARDWARE INSTALLATION
2.7.1 Configuring Method
• Method 1: LCD Panel with Keypad
You can use LCD front panel and keypad function to simply create
the RAID volume. The LCD status panel also informs you of the
disk array’s current operating status at a glance. For additional
information on using the LCD to configure the RAID subsystem
see the Chapter 4 of LCD Configuration Menu on the user
manual. The LCD provides a system of screens with areas for
information,status indication, or menus. The LCD screen displays
up to two lines at a time of menu items or other information.
When the SAS RAID subsystem is fully booted up and running
under normal conditions, the LCD screen shows the company
name and IP address, as shown below:
• Method 2: RS-232 Port Connection
For additional information on using the RS-232 port to configure
the SAS RAID subsystem see the Chapter 5 of VT-100 Utility
Configuration on the user manual.
Note:
It's a good ideal to turn on your SAS RAID subsystem before
turning on the host computer. This will insure that the host
computer recognize the volumes and drivers in the SAS
RAID subsystem.
33
HARDWARE INSTALLATION
• Method 3: LAN Port Connection
For additional information on using the LAN port to configure
the RAID subsystem see the Chapter 6 of Web Browser-Based
Configuration on the user manual.
2.7.2 Format, Partition and Mount the SAS RAID
Subsystem Volumes
Safety checks the installation. Connect all power cords. Turn on
the AC power switch at the rear of host computer then press the
power button at the front of the host computer.
After you create a unit, it needs to be partitioned, formatted,
and mounted by the operating system. There are various steps,
that depend on what operating system you are using (Windows,
Linux, FreeBSD or Mac, etc.). Detailed steps for each operating
system are provided on their disk utility. After that, the SAS RAID
subsystem can be fully used.
