Technical white paper | AHCI and RAID on HP EliteDesk and EliteOne 800 Business PCs

Introduction

This white paper covers the Advanced Host Controller Interface (AHCI) and Redundant Array of Independent Disks (RAID)

drive technologies that are provided on the HP Compaq EliteDesk/EliteOne 800 Business PC products. This white paper

provides a basic overview of AHCI and RAID technology, factory configurations, other supported RAID configurations, and

basic instructions on how to migrate non-RAID to RAID configurations in the field. HP also provides a Smart IV Hard Drive

technical white paper for Smart IV Technology on HP Business Desktop Hard Drives on www.hp.com. The HP Compaq Elite

800 also supports disk caching, which is described in a separate white paper “Configuring HP EliteDesk/EliteOne 800

Systems for Intel Smart Response Technology” available on

www.hp.com.

AHCI is a hardware mechanism that allows software to communicate with Serial ATA (SATA) devices. It is enumerated as a

PCI device and it transfers data between system memory and SATA devices.

HP EliteDesk/EliteOne 800-series Business PC products provide support for AHCI in single and multiple drive configurations.

RAID (Redundant Array of Independent Disks) employs two or more drives in combination for fault tolerance and

performance. Initially used with servers, desktop PCs are increasingly using RAID by adding a RAID controller and extra IDE

or SCSI disks.

HP EliteDesk/EliteOne 800-series Business PCs take advantage of Serial Advanced Technology Attachment (SATA)

technology and the integration of RAID support into select Intel chipsets. Both the EliteDesk and EliteOne 800 business PCs

use the Q87 Express chipset.
