INTRODUCTION

1. Introduction

This section presents a brief overview of the 6Gb/s SAS RAID control-

ler, ARC-1882 series. (PCIe 2.0 to 6Gb/s SAS RAID controllers)

1.1 Overview

SAS 2.0 is designed for much higher speed data transfer than pre-

vious available and backward compatibility with SAS 1.0. The

6Gb/s SAS interface supports both 6Gb/s and 3Gb/s SAS/SATA

disk drives for data-intensive applications and 6Gb/s or 3Gb/s

SATA drives for low-cost bulk storage of reference data. The

ARC-1882 family includes 8 ports low prole as well as 12/16/24

internal ports with additional 4 external ports models. The ARC-

1882LP/1882i/1882x support eight 6Gb/s SAS ports via one inter-

nal & one external/two internal/two external mini SAS connector.

The ARC-1882ix-12/16/24 attaches directly to SATA/SAS midplanes

with 3/4/6 SFF-8087 internal connector or increase capacity using

one additional SFF-8088 external connector. When used with 6Gb/s

SAS expanders, the controller can provide up to (128) devices

through one or more 6Gb/s SAS JBODs, making it an ideal solution

for enterprise-class storage applications that called for maximum

conguration exibility.

ARC-1882LP/1882i/1882x 6Gb/s RAID controllers are low-prole

PCI cards, ideal for 1U and 2U rack-mount systems. These control-

lers utilize the same RAID kernel that has been eld-proven in ex-

isting external RAID controller products, allowing Areca to quickly

bring stable and reliable PCIe 2.0 6Gb/s SAS RAID controllers to

the market.

Unparalleled Performance

The 6Gb/s SAS RAID controllers raise the standard to higher per-

formance levels with several enhancements including new high

performance dual core ROC Processor, a DDR3-1333 memory

architecture and high performance PCIe 2.0 x8 lane host interface

bus interconnection. The low prole controllers by default sup-

port on-board 1G of ECC DDR3-1333 SDRAM memory. The ARC-

1882ix-12/16/24 controllers each include one 240-pin DIMM socket
