Intel Rapid Storage Applied science
(RST), until 2010 chosen
Matrix RAID, is a
firmware-based RAID
solution built into a broad range of
Intel
chipsets. Every bit of 2020, it includes a
RAID
system capable of
RAID levels
0, one, five, and 10, a
block level
SSD
caching accelerator
(“Smart Response Engineering“) with support for
write-back
and
write-through
modes for speed or data protection of whatsoever disk or RAID assortment, and support for intelligent caching, speedy recovery from certain problems, and for
PCI Limited
based drives. Intel RST comes in two variants,
RST
for desktops, and
RSTe
(VROC
is a part of Intel RSTe
<sup>[ane]


[2]</sup>
) for enterprise scenarios, although for many chipsets, the user can choose equally both variants will operate correctly.
^[3]

Intel RST is provided past a combination of
firmware,
chipset
and
CPU
capabilities, and
software. As such, the chipset, the firmware included in the
BIOS, and the software installed past the user, must be compatible versions.
Online forums
and communities be which compare the benefits of different versions of these, suggest equally to best compatibility for specified hardware, and modify existing firmware and software to allow optimal combinations or updates beyond those provided by the hardware manufacturers.
^[iv]

Like all
RAID
(Redundant Array of Contained Disks), Intel RST RAID employs two or more physical
hard disks
which the operating system will treat as a single disk, in order to increase redundancy which avoids information loss (except RAID 0), and/or to increment the speed at which data is written to and/or read from a disk. Intel RST RAID does not provide new
RAID levels. It allows different areas (east.chiliad. partitions or logical volumes) on the same disk to be assigned to different RAID devices, unlike some other RAID controllers. Intel recommends to put any critical applications and data on a RAID 1, 5, or 10 volume, with redundancy to protect against data loss. The RAID 0 volume in Matrix RAID provides fast admission to large files where data loss is non a critical consequence but speed is; examples include video editing,
swap files, and files that are backed upwards. Intel Matrix RAID, Intel Rapid RAID, and Intel
Smart Response Technology
are together described as
Intel Rapid Storage Technology.

Operating system support

[
edit

“Rapid Storage Engineering” (RST), including creation of RAID volumes, works under
Windows 7
and newer versions of
Microsoft Windows. The older “Intel Matrix RAID” is supported under
Microsoft Windows XP.

Linux
supports Matrix RAID and Rapid Storage Technology (RST) through
device mapper, with
dmraid
tool, for RAID 0, 1 and 10. And
Linux Md RAID, with
mdadm
tool, for RAID 0, 1, 10, and 5. Fix of the RAID volumes must be done by using the ROM option in the Matrix Storage Managing director, so further configuration tin can be done in DM-RAID or Doctor-RAID.
^{[half dozen]}

FreeBSD
and
MidnightBSD
back up Intel Matrix RAID using the “ataraid” commuter, managed through the atacontrol command.
<sup>[7]


[8]</sup>

However, with older versions<sup>[

when?

]</sup>
of FreeBSD there were critical reliability issues which include array device renaming when a disk in an array is replaced,
^[nine]

an array existence considered healthy if the machine reboot/crashes during an array rebuild,
^[10]

and kernel panics when a disk is lost or is removed from the double-decker.
<sup>[11]


[12]</sup>

Some of these problems, when experienced in combination, could consequence in the loss of an entire assortment (even in the example of RAID 1).

VMware ESXi
4 does not support any RAID function nor Intel Matrix RAID based on Intel ICHxR controllers.
^[13]

PGPDisk
does not support Intel Matrix RAID based on Intel ICHxR, and does not support standalone drives if the “RAID” mode is enabled on the motherboard.

Matrix Storage Manager option ROM

[
edit
]

The Intel Matrix Storage Manager (IMSM)
pick ROM
is a part of Matrix RAID that has to exist used in the
BIOS
to create new RAID arrays.
^[xiv]

Every bit of 2014
^[update]

Intel uses “Rapid Storage Technology” -“Option Rom”- on its new chipsets, dropping the “Matrix” proper name.
<sup>[15]


[16]</sup>

An Intel document notes that Matrix RAID storage inverse to RST (Rapid Storage Engineering science) beginning with version 9.5.
^[17]

There have been several commuter versions:

Since release xi.2.0.0000,
TRIM
commands tin be read by Windows RAID drivers fabricated for 7 series chipsets. There is no RAID mode TRIM support on drivers for older chipsets.
^[22]

Intel states that RST support was added for the X79 chipset in RST version 11.6.0.0000 and later.
^[23]

On some 6 series chipsets there is a modification for the
ROM
in the BIOS, which will allow TRIM support on the half-dozen serial chipset.
^[24]

For the X79 chipset, certain motherboard manufacturers accept added both RAID ROMs in the BIOS, the RST and RST-E ROM. X79 is the Enterprise version, chosen RST-E. With the RST ROM added to the BIOS, this allows TRIM function to pass through the controller and TRIM SSD drives when RAID is enabled. This workaround was needed before RST-E driver version 3.eight was shipped which passed through TRIM commands to a RAID array without modifications to the RST-E ROM. There is no back up for TRIM in the RST-E version of the ROM when RAID is enabled and the RST-E driver version is less than 3.8.
^[25]

It is possible to add together an RST ROM to the BIOS to enable TRIM passthrough in RAID style past using the RST ROM and driver.
^[24]

The newest Option ROM version is a xiii series ROM, this ROM will not be used past motherboard manufacturers for the X79 chipset BIOS, and information technology tin can be injected into a BIOS to employ on the X79 with modded code, for those MFG’due south who have added a ROM switch, this is where the MFG has added both RST and RSTe to the RAID pick of a BIOS, simply in that location needs to be a code added for TRIM commands to be sent, when you inject the RST and supervene upon the RSTe with RST option ROM in X79 boards that exercise not contain the ROM switch, TRIM can be dysfunctional.

In that location are modded RST xiii serial Selection ROMs (legacy) available at certain BIOS modding sites that have been made functional for employ in the X79 chipsets.

When booting in a BIOS environment (legacy) and some / EFI, the RST selection ROM is used. When booting in a true UEFI environment the Option ROM is non used as a SataDriver with the RST version takes over. In BIOS mode the legacy/BIOS booting is under CSMCORE. In truthful UEFI mode the RST is controlled under SataDriver in BIOS.

The Intel RAID ROM is the firmware in the motherboard BIOS that is used to create the RAID assortment.

Notation: The RST drivers can exist used for RAID and also on a single drive every bit it contains an AHCI commuter. In that location is a issues in the version 12.5.0.1066 RST commuter, which cause TRIM commands not to laissez passer through the RAID commuter to the drives. TRIM is disabled using this driver.

Rapid Storage Technology enterprise (Intel RSTe)

Intel Rapid Storage Technology enterprise (Intel RSTe)
^[26]

provides performance and reliability for supported systems equipped with Serial ATA (SATA) devices, Serial Attached SCSI (SAS) devices, and/or solid state drives (SSDs) to enable an optimal enterprise storage solution. The principal divergence between RST and RSTe is that the RST is used for desktop systems and the RSTe is mostly used for server systems.
<sup>[27]

description needed

RST supports regular SATA controllers from desktop systems.

If the BIOS of the motherboard has RSTe characteristic then the user cannot install Intel Rapid Storage Technology software (error message: This platform is not supported). The user has to install RSTe software.

There have been several Option ROM versions:

In 2010,
Intel
announced that the RTSe branding would be replaced, with RSTe consolidated into Intel’southward VROC (Virtual RAID on CPU) product line.

Intel VROC (Virtual RAID on CPU)

This section needs expansion. You can assistance by adding to it. (February 2020)

Intel VROC is a office of Intel RSTe. This was mostly designed with
NVMe
SSD’due south in mind and it is direct attached to the Intel Xeon Scalable processors. For the full functionality information technology uses a newer Intel applied science called Intel VMD (Intel Volume Direction Device).

Intel VMD is a technology from the Intel Xeon Scalable processors serial and is used to provide hot-plug, surprise-removal, and LED management of NVMe SSD’due south for server usage. Intel VROC is targeted for Linux operating systems, Microsoft Windows Server, Microsoft Windows 7 and Microsoft Windows ten. For customer PC’southward (with Intel Core, Pentium and Celeron processors) Intel RST is still the advised software package to use.
