1. Introduction
This section presents a brief overview of the SAS RAID controller, ARC-
1212/1222 series. (PCIe to SAS/SATA RAID controllers)
1.1 Overview
SAS builds on parallel SCSI by providing higher performance,
improving data availability, and simplifying system design. The
SAS interface supports both SAS disk drives for data-intensive
applications and Serial ATA (SATA) drives for low-cost bulk storage
of reference data. The ARC-1212/1222 support directly attach 4/8
SAS ports via one internal /two internal Min SAS connector. Each
port on the SAS controllers supports SAS and/or SATA devices.
Since there is no expander support on those boards, this can
meet the customer inquiry SAS solution (using same enclosure) to
replace SATA solution. The ARC-1212/1222 RAID controllers only
support directly attach to 4/8 SAS/SATA drives without supporting
the expand function.
The ARC-1212/1222 RAID controllers are low-prole PCIe cards,
ideal for 1U and 2U rack-mount systems without needing the ex-
pansion capability. These controllers utilize the same RAID kernel
that has been eld-proven in existing external RAID controller
products, allowing Areca to quickly bring stable and reliable RAID
controllers to the market
Unparalleled Performance
The SAS RAID controllers raise the standard to higher performance
levels with several enhancements including Intel new high-perfor-
mance I/O Processor, a DDR2-533 memory architecture and high
performance PCIe x8 Link host interface bus interconnection. The
low prole controllers by default support on-board 256MB of ECC
DDR2-533 SDRAM memory with optional battery backup module
The test result is against overall performance compared to other
SAS RAID controllers. The powerful Intel new I/O processors inte-
grated 4/8-port SAS I/O ports on chip delivers high performance
for servers and workstations.

INTRODUCTION
11
Unsurpassed Data Availability
As storage capacities continue to rapidly increase, users need
greater level of disk drive fault tolerance, which can be implement-
ed without doubling the investment in disk drives. The RAID
6 can offer fault tolerance greater that RAID 1 or RAID 5 but only
consumes the capacity of 2 disk drives for distributed parity data.
The SAS RAID controllers with extreme performance RAID 6 engine
installed provide the highest RAID 6 feature to meet this require-
ment. The controller can concurrently compute two parity blocks
and get very similar RAID 5 performance.
The SAS RAID controllers can also provide RAID levels 0, 1, 10, 3,
5, 6, 30, 50, 60, Single Disk or JBOD for maximum conguration
exibility. Its high data availability and protection derives from
the following capabilities: Online RAID Capacity Expansion, Array
Roaming, Online RAID Level / Stripe Size Migration, Global Online
Spare, Automatic Drive Failure Detection, Automatic Failed Drive
Rebuilding, Disk Hot-Swap, Online Background Rebuilding, Instant
Availability/Background Initialization, Auto Reassign Sector, Redun-
dant Flash Image and Battery Backup Module. Greater than Two
TB Support allows for very large volume set application in 64-bit
environment such as data-mining and managing large databases.
Maximum Interoperability
The SAS RAID controller support broad operating system including
Windows Vista/Server 2003/XP/2000, Linux (Open Source), Free-
BSD (Open Source), Solaris (Open Source), Mac and more, along
with key system monitoring features such as enclosure manage-
ment (SGPIO) and SNMP function. Our products and technology
are based on extensive testing and validation process; leverage
Areca SATA RAID controller eld-proven compatibility with operat-
ing systems, motherboards, applications and device drivers.

INTRODUCTION
12
Easy RAID Management
The controllers contain an embedded McBIOS RAID manager that
can access via hot key at M/B BIOS boot-up screen. This pre-boot
McBIOS RAID manager can use to simplify the setup and manage-
ment of RAID controller. The controller rmware also contains a
browser-based McRAID storage manager which can be accessed
through the Ethernet port or ArcHttp proxy server in Windows,
Linux, FreeBSD and more environments. The McRAID storage man-
ager allows local and remote to create and modify RAID set, vol-
ume set, and monitor RAID status from standard web browser. The
Single Admin Portal (SAP) monitor utility can support one applica-
tion to scan 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.

2.2 Board Layout
The controller can support a family included 4/8 ports models with
1/2 internal SFF-8087 connectors. This section provides the board
layout and connector/jumper for the SAS RAID controller.

HARDWARE INSTALLATION
17
Tools Required
An ESD grounding strap or mat is required. Also required are stan-
dard hand tools to open your system’s case.
System Requirement
The SAS RAID controller can be installed in a universal PCIe slot
and requires a motherboard that:
ARC-1212/1222 series SAS RAID controller requires:
• Comply with the PCIe x8
It can work on the PCIe x1, x4, x8, and x16 signal with x8 or x16
slot M/B.
Installation Tools
The following items may be needed to assist with installing the
SAS RAID controller into an available PCIe expansion slot.
• Small screwdriver
• Host system hardware manuals and manuals for the disk or
enclosure being installed.
Personal Safety Instructions
Use the following safety instructions to help you protect your
computer system from potential damage and to ensure your own
personal safety.
• Always wear a grounding strap or work on an ESD-protective
mat.
• Before opening the system cover, turn off power switches and
unplug the power cords. Do not reconnect the power cords until
you have replaced the covers.

HARDWARE INSTALLATION
18
Electrostatic Discharge
Static electricity can cause serious damage to the electronic com-
ponents on this SAS RAID controller. To avoid damage caused by
electrostatic discharge, observe the following precautions:
• Do not remove the SAS RAID controller from its anti-static
packaging until you are ready to install it into a computer case.
• Handle the SAS RAID controller by its edges or by the metal
mounting brackets at its each end.
• Before you handle the SAS RAID controller in any way, touch a
grounded, anti-static surface, such as an unpainted portion of the
system chassis, for a few seconds to discharge any built-up static
electricity.
2.3 Installation
Use the following instructions below to install a PCIe SAS RAID
controller.
Step 1. Unpack
Unpack and remove the PCIe SAS RAID controller from the pack-
age. Inspect it carefully, if anything is missing or damaged, contact
your local dealer.
Step 2. Power PC/Server Off
Turn off computer and remove the AC power cord. Remove the
system’s cover. For the instructions, please see the computer sys-
tem documentation.
Warning:
High voltages may be found inside computer equipment. Before
installing any of the hardware in this package or removing the
protective covers of any computer equipment, turn off power
switches and disconnect power cords. Do not reconnect the
power cords until you have replaced the covers.

Figure 2-2, Insert SAS RAID controller into a PCIe slot
Step 3. Install the PCIe SAS RAID Cards
To install the SAS RAID controller, remove the mounting screw and
existing bracket from the rear panel behind the selected PCIe slot.
Align the gold-ngered edge on the card with the selected PCIe
slot. Press down gently but rmly to ensure that the card is prop-
erly seated in the slot, as shown in Figure 2-6. Then, screw the
bracket into the computer chassis. ARC-1212/1222 series cards
require a PCIe x8 slot.
Step 4. Mount the Drives
You can connect the SAS/SATA drives to the controller through
direct cable and backplane solutions. In the direct connection,
SAS/SATA drives are directly connected to SAS RAID controller PHY
port with SAS/SATA cables. The SAS RAID controller can support
up to 4/8 PHY ports. Remove the front bezel from the computer
chassis and install the cages or SAS/SATA drives in the computer
chassis. Loading drives to the drive tray if cages are installed. Be
sure that the power is connected to either the cage backplane or
the individual drives.

Figure 2-3, SAS Cable Connect to HD
In the backplane solution, SAS/SATA drives are directly connected
to SAS/SATA system backplane. The number of SAS/SATA drives is
limited to the number of slots available on the backplane.
Step 5. Install SAS Cable
This section describes SAS cable how to connect on controller.
