Intel R Rapid Storage Technology Enterprise
Diagram of an Intel RST setup
Intel Rapid Storage Technology (RST), until 2010 called 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, 1, v, and 10, a block level SSD caching accelerator ("Smart Response Technology") with support for write-back and write-through modes for speed or data protection of whatsoever disk or RAID array, and back up for intelligent caching, speedy recovery from certain issues, and for PCI Express based drives. Intel RST comes in 2 variants, RST for desktops, and RSTe (VROC is a part of Intel RSTe[one] [ii]) for enterprise scenarios, although for many chipsets, the user can choose as both variants will operate correctly.[three]
Intel RST is provided by a combination of firmware, chipset and CPU capabilities, and software. As such, the chipset, the firmware included in the BIOS, and the software installed by the user, must be compatible versions. Online forums and communities exist which compare the benefits of different versions of these, advise equally to best compatibility for specified hardware, and modify existing firmware and software to let optimal combinations or updates beyond those provided by the hardware manufacturers.[4]
Like all RAID (Redundant Array of Independent Disks), Intel RST RAID employs 2 or more than physical difficult disks which the operating organisation volition treat every bit a unmarried disk, in order to increment redundancy which avoids data loss (except RAID 0), and/or to increase the speed at which data is written to and/or read from a deejay. Intel RST RAID does not provide new RAID levels. It allows different areas (east.g. partitions or logical volumes) on the aforementioned disk to exist 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 book in Matrix RAID provides fast admission to large files where data loss is non a critical issue but speed is; examples include video editing, swap files, and files that are backed up. Intel Matrix RAID, Intel Rapid RAID, and Intel Smart Response Technology are together described as Intel Rapid Storage Technology.[5]
Operating system support [edit]
"Rapid Storage Technology" (RST), including creation of RAID volumes, works nether Windows vii 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, ane and 10. And Linux Doc RAID, with mdadm tool, for RAID 0, 1, 10, and 5. Set up of the RAID volumes must be done by using the ROM option in the Matrix Storage Director, then further configuration tin can exist done in DM-RAID or MD-RAID.[half-dozen]
FreeBSD and MidnightBSD support Intel Matrix RAID using the "ataraid" driver, managed through the atacontrol command.[7] [8] However, with older versions[ when? ] of FreeBSD there were disquisitional reliability issues which include assortment device renaming when a disk in an assortment is replaced,[9] an array beingness considered good for you if the machine reboot/crashes during an array rebuild,[10] and kernel panics when a disk is lost or is removed from the jitney.[11] [12] Some of these problems, when experienced in combination, could result in the loss of an entire array (even in the example of RAID ane).
VMware ESXi 4 does not support any RAID function nor Intel Matrix RAID based on Intel ICHxR controllers.[13]
PGPDisk does non 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 Director (IMSM) pick ROM is a role of Matrix RAID that has to be used in the BIOS to create new RAID arrays.[14] As of 2014[update] Intel uses "Rapid Storage Technology" -"Option Rom"- on its new chipsets, dropping the "Matrix" name.[15] [16] An Intel document notes that Matrix RAID storage changed to RST (Rapid Storage Technology) beginning with version ix.5.[17]

Since release 11.ii.0.0000, TRIM commands can be read past Windows RAID drivers fabricated for 7 series chipsets. In that location is no RAID mode TRIM support on drivers for older chipsets.[22]
Intel states that RST back up was added for the X79 chipset in RST version 11.6.0.0000 and subsequently.[23]
On some 6 serial chipsets there is a modification for the ROM in the BIOS, which will allow TRIM back up on the 6 series chipset.[24]
For the X79 chipset, certain motherboard manufacturers accept added both RAID ROMs in the BIOS, the RST and RST-Due east 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 earlier RST-East commuter version 3.eight was shipped which passed through TRIM commands to a RAID array without modifications to the RST-E ROM. In that location is no support for TRIM in the RST-Eastward version of the ROM when RAID is enabled and the RST-Eastward driver version is less than three.viii.[25] It is possible to add an RST ROM to the BIOS to enable TRIM passthrough in RAID mode past using the RST ROM and driver.[24]
The newest Option ROM version is a xiii series ROM, this ROM will non exist used by motherboard manufacturers for the X79 chipset BIOS, and it can be injected into a BIOS to use on the X79 with modded lawmaking, for those MFG'southward who have added a ROM switch, this is where the MFG has added both RST and RSTe to the RAID selection of a BIOS, merely there needs to be a code added for TRIM commands to be sent, when you inject the RST and replace the RSTe with RST choice ROM in X79 boards that do not comprise the ROM switch, TRIM can be dysfunctional.
There are modded RST 13 series Pick ROMs (legacy) available at sure BIOS modding sites that have been made functional for use in the X79 chipsets.
When booting in a BIOS environment (legacy) and some / EFI, the RST option ROM is used. When booting in a truthful UEFI environment the Selection ROM is not used as a SataDriver with the RST version takes over. In BIOS mode the legacy/BIOS booting is under CSMCORE. In true UEFI mode the RST is controlled nether SataDriver in BIOS.
The Intel RAID ROM is the firmware in the motherboard BIOS that is used to create the RAID array.
Notation: The RST drivers can be used for RAID and too on a single drive as it contains an AHCI driver. There is a problems in the version 12.5.0.1066 RST commuter, which cause TRIM commands non to laissez passer through the RAID driver to the drives. TRIM is disabled using this driver.
Rapid Storage Engineering enterprise (Intel RSTe) [edit]
Intel Rapid Storage Technology enterprise (Intel RSTe)[26] provides performance and reliability for supported systems equipped with Serial ATA (SATA) devices, Series Attached SCSI (SAS) devices, and/or solid state drives (SSDs) to enable an optimal enterprise storage solution. The principal difference between RST and RSTe is that the RST is used for desktop systems and the RSTe is mostly used for server systems.[27] [ description needed ] RST supports regular SATA controllers from desktop systems.
If the BIOS of the motherboard has RSTe feature and then the user cannot install Intel Rapid Storage Engineering science software (error message: This platform is not supported). The user has to install RSTe software.
In that location accept been several Choice ROM versions:
| Version | Release date | Notes |
|---|---|---|
| v4.3.0.1010 | 2014 | This version is installed on some Intel C236 Chipset-based motherboards (e.g. Asus P10S WS) |
In 2019, Intel announced that the RTSe branding would exist replaced, with RSTe consolidated into Intel'southward VROC (Virtual RAID on CPU) product line.[1]
Intel VROC (Virtual RAID on CPU) [edit]
![[icon]](https://cdn.statically.io/img/www.herodictionary.com//upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Wiki_letter_w_cropped.svg/20px-Wiki_letter_w_cropped.svg.png){kind=small} | This section needs expansion. You can help by calculation to information technology. (February 2020) |
Intel VROC is a part of Intel RSTe. This was mostly designed with NVMe SSD'south in mind and information technology is directly attached to the Intel Xeon Scalable processors. For the full functionality it uses a newer Intel engineering science chosen Intel VMD (Intel Volume Management 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's for server usage. Intel VMD is targeted for Microsoft Windows, and Linux operating systems. For client PC'south (with Intel Core, Pentium and Celeron processors) Intel RST is still the advised software package to apply.[28]
Criticism on Intel RST applied science [edit]
The software created by Intel to manage the RAID configuration is under par.
E.g. when using a RAID 1 configuration, Windows shall testify a temporary message when i of the disk are down, yet if this is not noticed (because the user is not at the estimator), the user might not discover the disk failure in time.
Furthermore the Intel RST software does not consistently log status changes (repair/rebuilds) in the Windows Eventlog, making it difficult for 3rd party monitoring software to warn users when the RAID status changes and the data might exist in jeopardy.
Other strange decision Intel has made, is to remove the e-mail service warning from the latest version (v19.10) of the software. On earlier versions (18.x) the email warning can be configured, but lacks the modern fields like password and SSL/TLS hallmark to be used with modern e-mail service providers like Gmail, Microsoft'southward Outlook and e-mail accounts from other providers.
Besides when field tested (with an older mail server *without hallmark*), no warnings were e-mailed. This email service was also inconsistent because the disk degradation was non eastward-mailed, but consequently the finished rebuild of the RAID was e-mailed, without the user ever being warned the computer was rebuilding the RAID drive.
Intel as well used to accept a command line software (CLI) for their RST RAID, which 1 could employ to asking the status of the RAID drives, however this software was deprecated.
The decision might exist made that Intel is deliberately undermining the reliability of the RAID, by crippling the methods to warn the user before data is lost.
