D
Setting Up SATA RAID or AHCI Modes
AHCI Mode
Advanced Host Controller Interface (AHCI) is an interface specification that allows the storage driver to enable
advanced Serial ATA features such as Native Command Queuing (for maximum hard disk efficiency and per-
formance). AHCI mode can be supported by one, two or three hard disks.
RAID
You may use your hard disks (if you have included more than one hard disk in your purchase option) in combi-
nation with Striping (RAID 0), Mirroring (RAID 1) or Parity Across Disks (RAID 5) for either fault tolerance
or performance. To configure your system in Striping (RAID 0) or Mirroring (RAID 1) modes you will require
at least two hard disks; to configure your system in Parity Across Disks (RAID 5) mode you will require three
hard disks installed.
Table D - 4 - RAID Levels
RAID Level Description
RAID 0
Identical drives reading and writing data in parallel to increase performance. RAID 0 implements a striped disk
array and the data is broken into blocks and each block is written to a separate disk drive.
RAID 1
Identical drives in a mirrored configuration used to protect data. Should a drive that is part of a mirrored array fail,
the mirrored drive (which contains identical data) will handle all the data. When a new replacement drive is installed,
data to the new drive is rebuilt from the mirrored drive to restore fault tolerance.
RAID 5
Identical drives (at least three drives must be used) in a parity across disks configuration are used to protect data
and increase performance. A RAID 5 array can withstand a single disk failure without losing access to data.
