INTRODUCTION
1. Introduction
This section presents a brief overview of the SATA RAID Series controller, ARC-1110/1110ML/1120/1120ML/1130/1130ML/1160/ 1160ML/1170 (4/8/12/16/24-port PCI-X SATA RAID Controllers) and ARC-1210/1220/1230/1230/1231ML/1260/1261ML/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
IIperipheral devices (depending on model) on a single controller. The ARC-11xx series for the PCI-X bus and the ARC-12xx Series for the PCI-Express bus. When properly configured, these SATA controllers 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 controllers utilize the same RAID kernel that has been field-proven in Areca existing external RAID controllers, allowing Areca to quickly bring stable and reliable RAID controllers to the market.
Unparalleled Performance
The SATA RAID controllers provide reliable data protection for desktops, workstations, and servers. These cards set the stan- dard with enhancements that include a high-performance Intel I/O Processor, a new memory architecture, and a high performance PCI bus interconnection. The 8/12/16/24-port controllers with the RAID 6 engine built-in can offer extreme-availability RAID 6 functionality. This engine can concurrently compute two parity blocks with per- formance very similar to RAID 5. The controllers by default support 256MB of ECC SDRAM memory. The 12/16/24 port controllers sup- port 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 4/8 channel SATA PCI-X controller
