1. Introduction
This section presents a brief overview of the ARC-4038 compact tower
12Gb/s SAS JBOD enclosure.
1.1 Overview
The ARC-4038 SAS-to-SAS JBOD box provides a compact external
storage chassis capable of accommodating up to 8/12 12Gb/s Se-
rial-Attached SCSI (SAS) drives or 6Gb/s Serial ATA (SATA) drives.
The box can support both 3.5-inch disk drives and 2.5-inch disk
drives, each one contained in its individual hole on the disk carrier.
The expander module on ARC-4038 is designed with an integrated
ARM Cortex-R4 processor for topology management functions such
as discovery, enclosure and drive management, and LED manage-
ment. Each ARC-4038 compact tower JBOD supports four 12Gb/s
SFF-8644 and one 6Gb/s SFF-8088 SAS host and expansion con-
nections. Out-of-band CLI can re-dene manufacture default set-
ting on those connections. Conguration and environmental in-
formation is accessible either via in-band (SES-3.0 over SMP) or
out-of-band serial port.
Unparalleled Performance
The 12Gb/s ARC-4038 offers 28 ports of connectivity in a 8/12-bay
desktop tower. It can provide internally connectivity for up to 8/12
direct attached SAS/SATA HDDs and or SSDs and 20 external ports
(using 4 x SFF-8644 and 1 x SFF-8088 connector) for storage host/
expansion connections. High performance architecture sets new
boundaries of industry performance expectations: 12Gb/s SAS or
6.0Gb/s and 3Gb/s SAS/SATA. The ARC-4038 incorporates the lat-
est enhancements in SAS along with new LSI DataBolt bandwidth
optimizer technology. This is designed to help facilitate the indus-
try transition to 12Gb/s SAS-enabled systems by allowing users
to take advantage of 12Gb/s speeds while utilizing existing 6Gb/s
drives and backplanes. Using DataBolt, the ARC-4038 buffers
6Gb/s data and then transfers it out to the host at 12Gb/s speeds
in order to match the bandwidth between faster hosts and slower
SAS or SATA devices.

INTRODUCTION

Easy Management
The ARC-4038 contains an embedded expander manager that can
access via in-band SES-3.0 over SMP protocol and out-of band RS-
232 port. An out-of-band serial port is available for managing the
conguration and monitoring the expander. The ARC-4038 expand-
er rmware and EPLD has implemented the SES-3.0 protocol and
disk activity map to the individual fault/activity status indicator on
the backplanes. It has implemented autonomous chassis manage-
ment of power supply status connectors, two fan monitor/speed
control connectors through the SES-3.0 protocol. In data center
environments, identifying issues with drives and environments are
crucial. The hardware monitor can monitor system voltage and em-
perature. The warning message will be shown in alarm buzzer and
respect LED.
Maximum Interoperability
Areca presents its ultra-high performance and high reliability
12Gb/s SAS expander module for a cost-effective and enterprise-
class JBOD storage enclosure. A 12Gb/s SAS expander module
literally expands the number of end devices that you can connect
together. Expander devices, typically embedded into an expander
module to connect system backplane, support large congurations
of SAS end devices, including SAS host/RAID adapters and SAS
and SATA disk drives. The SAS protocol denes a mechanism that
has been implemented in the SAS expanders to guarantee fair ac-
cess between drives in a domain. The ARC-4038 is ideal for 12Gb/s
SAS storage systems with external interfaces and get the benets
of more storage capacity. The type and total amount of drives you
use are based on the host interface in the server that the JBOD is
connected. Host-based RAID conguration is supported via an ex-
ternal connectors on PCIe to 12Gb/s SAS RAID controller, external
series SAS/Fibre/iSCSI to 12Gb/s SAS RAID and SAS host adapt-
ers.

Turn on the expander enclosure rst to make sure the SAS
RAID controller or SAS host adapter recognizes the drives in
the enclosure.
• Expander Port Connection
ARC-4038 SAS JBOD enclosure is a device that contains two
expander ports. Expander ports may support being attached to
SAS initiator ports, SAS and/or SATA target ports, and to other
expander ports. The SAS JBOD enclosure can support daisy-chain
how many SAS JBOD enclosures which depend on the host RAID
controller’s or server host adapter’s rmware. The following gure
shows how to connect the external Min SAS cable from the ARC-
4038 SAS JBOD enclosure to the external connectors on the ARC-
1883x. Daisy-chains longer than the limitation of subsystems are
not supported even if it may be workable.

HARDWARE INSTALLATION
17
Step 3. Connecting RS232C Monitor Port
You can connect RS-232 port to the manager clinet system. It is
easy to congure and manage the JBOD enclosure from the client
system. The ARC-4038 JBOD enclosure can be congured via a
VT-100 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 JBOD enclosure for access
to the text-based setup menu.
Step 4. Power Up the JBOD Enclosure
Turn on the AC power switch from power supply on the rear side
of the ARC-4038 JBOD enclosure.
a. Using the included power cord, connect this power cord to a
grounded electronical outlet and to the ARC-4038 JBOD enclo-
sure. (manufacture recommends that you use an uninterruptible
power supply to protect your ARC-4038 SAS JBOD enclosure.)
b. Turn on the AC power switch from the back of ARC-4038 JBOD
enclosure.
Figure 2-10, Connect the power cord to a grounded electrical
outlet and to the ARC-4038 JBOD enclosure.

HARDWARE INSTALLATION

Note:
It is a good idea to turn on your ARC-4038 Compact Tower-
JBOD enclosure before turning on the host computer. This
will insure that the host computer recognizes the volumes
and drives in the ARC-4038 JBOD enclosure. If you turn on
the host computer rst, be sure of your host subsystem
supporting hot-plug function or rescan command to recognize
the ARC-4038 JBOD enclosure again.
Step 5. Congure JBOD Enclosure
Your ARC-4038 JBOD enclosure can be congured by using a
serial device (terminal emulation). The ARC-4038 JBOD enclo-
sure can be congured via a VT-100 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 JBOD
enclosure for access to the text-based setup menu. For additional
information on using the RS-232 port to congure the JBOD en-
closure see the Chapter 3 of CLI Features.
Step 6. Turn on Host Computer Power
Safety checks the installation. Connect all power code. Turn on
the AC power switch at the rear of host computer then press the
power button at the front of the host computer.
Step 7. Format, Partition and Mount the ARC-4038 JBOD
Enclosure Volumes
After the volume set is ready for system accesses, it needs to be
partitioned, formatted, and mounted by the operating system.
There are various steps, depending 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 ARC-4038 JBOD enclosure can be fully used.

CLI FEATURES
19
3. CLI Features
This Command Line Interface (CLI) is provided for you to congure the
8 bays compact tower JBOD enclosure functions. The CLI is useful in
environments where a graphical user interface (GUI) is not available.
• Locations of RS-232C Port
The ARC-4038 JBOD enclosure uses the RJ11 port as the serial port
interface. Please use the cable included on the shipping box to con-
gure the expander controller.
• Establishing the Connection for the RS-232 Port
The CLI function can be done by using an ANSI/VT-100 compat-
ible terminal emulation program. You must complete the appropri-
ate installation procedure before proceeding with the CLI function.
Whichever terminal emulation program is used must support the
1K XMODEM le transfer protocol.
The serial port on the SAS expander controller’s back panel can
be used in VT100 mode. The provided interface cable converts the
RS-232 signal of the RJ11 connector on the SAS expander control-
ler into a 9-pin D-Sub male connector. The rmware-based termi-
nal SAS expander management interface can access the expander
through this RS-232 port. You can attach a VT-100 compatible
terminal or a PC running a VT-100 terminal emulation program to
the serial port for accessing the text-based setup menu.
3.1 Expander RS-232C Port Pin Assignment
To ensure proper communications between the SAS expander
controller and the VT-100 Terminal Emulation, Please congure the
VT100 terminal emulation settings to the values shown below:

By connecting a VT100 compatible terminal, or a PC operating in an
equivalent terminal emulation mode, all CLI administration func-
tions can be exercised from the VT100 terminal. There are a wide
variety of Terminal Emulation packages, but for the most part they
should be very similar. The following setup procedure is an example
setup VT100 Terminal in Windows XP system using Hyper Terminal
use Version 3.0 or higher.
Step 1. Open the “Taskbar Start”/”Programs"/"Accessories"/"Co
mmmunications"/"Heyper Terminal". (Heyper Terminal requires
