1. Introduction
This section presents a brief overview of the 2-port PCIe x1 SATA RAID
Controller.
1.1 Overview
The ARC-1200 SATA RAID controller is a PCIe x1 bus to SATA Disk
Array host controller. It can provide two SATA ll ports on a single
controller. When properly congured, the SATA RAID controller can
provide a high degree of performance and fault tolerance with data
mirroring for maximum protection. The ARC-1200 is the industry's
most compelling PCIe x1 to SATA ll RAID solution which economi-
cally delivers full-featured true hardware RAID to desktop and
workstations as well as entry-level servers.
Unparalleled Performance
The SATA RAID controller raises the standard to higher perfor-
mance levels with several enhancements including high-perfor-
mance 500MHz storage Processor, a new DDR2 memory architec-
ture (DDR400), 3Gb/s SATA ll ports, and NCQ support in a high
performance PCIe x1 bus interconnection. The ARC-1200 default
supports on-board DDR2-400 SDRAM memory. The test result is
against overall performance compared to other standard SATA con-
troller.
Unsurpassed Data Availability
With Areca entry-level RAID controllers incorporate onboard stor-
age processors to deliver true hardware RAID. Hardware RAID
cards have their own local RAID processor onboard, plus dedicated
onboard cache for full hardware ofoading of RAID-processing
functions. The ability of hardware RAID controllers to rebuild an ar-
ray in the event of a drive failure is superior to what software RAID
controllers offer.
The SATA RAID controller can provide RAID levels 0, 1, Single Disk
or JBOD RAID for maximum conguration exibility. Its high data
availability and protection derives from the following capabilities:
