Setting Up SATA RAID, Optane™ or AHCI Mode
Note that your system can be set up as a RAID OR to support Intel® Optane™,
it cannot be set to support both systems.
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 performance). AHCI mode can be
supported by one or two hard disks/solid state drives. Make sure you install the In-
tel® Rapid Storage Technology application if you have set up your HDDs/SSDs
in AHCI mode (see “Intel® Rapid Storage Technology” on page 6 - 55)
Intel® Optane™
Intel® Optane™ is a combination of a compatible memory device and Intel Rapid
Technology software. This combination is designed to speed up your system per-
formance by caching boot data, executables, frequently accessed data and system
page files to an non volatile, low latency Intel® Optane™ SSD.
Contact your distributor or supplier to see if your system supports this technology.
RAID
To configure your RAID (Redundant Array of Independent Disks) system in Strip-
ing (RAID 0) or Mirroring (RAID 1) modes (see Table 6 - 1, on page 6 - 4) you will
require at least two identical (see sidebar) HDDs/SSDs.
RAID Hard Disks/
Solid State Drives
All HDDS/SSDs in a
RAID should be identi-
cal (the same size and
brand) in order to pre-
vent unexpected system
behavior.
SATA Mode
Selection
The SATA mode selec-
tion should be made be-
fore installing your
operating system.
DO NOT change your
selected SATA mode
unless you intend to re-
install your operating
system. Make sure you
have backed up all your
data before doing so.
