1. Introduction
This section presents a brief overview of the SATA RAID Series con-
troller cards, ARC-1110/1110ML/1120/1120ML/1130/1130ML/1160/
1160ML/1170 (4/8/12/16/24-port PCI-X SATA RAID Controllers) and
ARC-1210/1220/1230/1230/1230ML/1260/1260ML/1280/1280ML
(4/8/12/16/24-port PCI-Express SATA RAID Controllers).

1.1 Overview

The ARC-11xx and ARC-12xx Series of high-performance Serial ATA
RAID controllers support a maximum of 4, 8, 12, 16, or 24 SATA-
II peripheral devices (depending on model) on a single controller
card. The ARC-11xx Series are for the PCI-X bus and the ARC-12xx
Series are for the PCI-Express bus. When properly configured,
these SATA controllers can provide non-stop service with a high
degree of fault tolerance through the use Of RAID technology and
can also provide advanced array management features.
The 4 and 8 port SATA RAID controllers are low-profile PCI cards,
ideal for 1U and 2U rack-mount systems. These cards utilize the
same RAID kernel that has been field-proven in existing external
RAID controller products, allowing Areca to quickly bring stable and
reliable RAID controllers to the market.
Unparalleled Performance
Areca RAID controllers provide reliable data protection for desk-
tops, workstations, and servers. These cards set the standard with
enhancements that include a high-performance Intel I/O Proces-
sor, a new DDR333 memory architecture, and a high performance
PCI bus interconnection. SATA RAID 8/12/16/24-port controllers
with the Areca RAID 6 engine built-in can offer extreme-availability
RAID 6 functionality. This engine can concurrently computes two
parity blocks with performance very similar to RAID 5. The control-
lers by default support 256MB of ECC DDR333 SDRAM memory.
The 12/16/24 port controllers support one DDR333 SODIMM socket
that allows for upgrading up to 1GB of memory. The 12/16/24
port controllers support one DDR2-533 DIMM socket that allows
for upgrading up to 2GB of memory. The controllers use Marvell
