Intel Rapid Storage Technology (RST), until 2010 called Matrix RAID, is a firmware-primarily based RAID solution constructed into a wide variety of Intel chipsets. As of 2020, it includes a RAID machine capable of RAID tiers 0, 1, 5, and 10, a block stage SSD caching accelerator ("Smart Response Technology") with support for write-again and write-through modes for pace or statistics safety of any disk or RAID array, and aid for wise caching, rapid restoration from positive problems, and for PCI Express based totally drives. Intel RST is available ineditions, RST for computers, and RSTe (VROC is part of Intel RSTe[1][2]) for organisation scenarios, although for many chipsets, the person can choose as both versions will function efficiently.[3]
Intel RST is furnished by using a mixture of firmware, chipset and CPU competencies, and software program. As such, the chipset, the firmware included within the BIOS, and the software program installed by the user, ought to be compatible variations. Online boards and groups exist which evaluate the advantages of various variations of those, propose as to satisfactory compatibility for distinctive hardware, and regulate existing firmware and software to permit optimal combos or updates past those supplied through the hardware manufacturers.[4]
Like all RAID (Redundant Array of Independent Disks), Intel RST RAID employsor more bodily difficult 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 boom the rate at which records is written to and/or study from a disk. Intel RST RAID does now not offer new RAID tiers. It lets in specific areas (e.g. partitions or logical volumes) on the identical disk to be assigned to different RAID devices, unlike a few different RAID controllers. Intel recommends to put any important programs and information on a RAID 1, 5, or 10 volume, with redundancy to guard in opposition to statistics loss. The RAID zero extent in Matrix RAID gives rapid access to massive documents wherein statistics loss isn't always a vital difficulty but speed is; examples include video enhancing, change documents, and documents which are backed up. Intel Matrix RAID, Intel Rapid RAID, and Intel Smart Response Technology are collectively defined as Intel Rapid Storage Technology.[five]Operating system guide[edit]
"Rapid Storage Technology" (RST), together with advent of RAID volumes, works beneath Windows 7 and more moderen variations of Microsoft Windows. The older "Intel Matrix RAID" is supported below Microsoft Windows XP.
Linux helps Matrix RAID and Rapid Storage Technology (RST) thru device mapper, with dmraid tool, for RAID 0, 1 and 10. And Linux MD RAID, with mdadm tool, for RAID zero, 1, 10, and five. Set up of the RAID volumes should be executed through the use of the ROM option within the Matrix Storage Manager, then further configuration can be achieved in DM-RAID or MD-RAID.[6]
FreeBSD and MidnightBSD guide Intel Matrix RAID using the "ataraid" motive force, controlled through the atacontrol command.[7][eight] However, with older variations[when?] of FreeBSD there were essential reliability problems which consist of array tool renaming whilst a disk in an array is replaced,[9] an array being considered wholesome if the gadget reboot/crashes at some point of an array rebuild,[10] and kernel panics whilst a disk is lost or is eliminated from the bus.[11][12] Some of these problems, whilst skilled in aggregate, could result in the loss of an entire array (even inside the case of RAID 1).
VMware ESXi 4 does now not help any RAID feature nor Intel Matrix RAID based on Intel ICHxR controllers.[thirteen]
PGPDisk does not guide Intel Matrix RAID based on Intel ICHxR, and does not guide standalone drives if the "RAID" mode is enabled on the motherboard.Matrix Storage Manager alternative ROM[edit]
The Intel Matrix Storage Manager (IMSM) choice ROM is a part of Matrix RAID that has to be used in the BIOS to create new RAID arrays.[14]As of 2014 Intel uses "Rapid Storage Technology" -"Option Rom"- on its new chipsets, losing the "Matrix" name.[15][16]An Intel document notes that Matrix RAID garage modified to RST (Rapid Storage Technology) starting with model nine.5.[17]

Since release eleven.2.0.0000, TRIM instructions can be examine with the aid of Windows RAID drivers made for 7 collection chipsets. There is no RAID mode TRIM support on drivers for older chipsets.[22]
Intel states that RST aid turned into brought for the X79 chipset in RST version eleven.6.zero.0000 and after.[23]
On a few 6 collection chipsets there is a change for the ROM inside the BIOS, so as to permit TRIM help at the 6 collection chipset.[24]
For the X79 chipset, positive motherboard manufacturers have delivered each RAID ROMs within the BIOS, the RST and RST-E ROM. X79 is the Enterprise version, known as RST-E. With the RST ROM delivered to the BIOS, this permits TRIM feature to pass through the controller and TRIM SSD drives when RAID is enabled. This workaround changed into wanted before RST-E driver model three.eight become shipped which surpassed thru TRIM instructions to a RAID array with out changes to the RST-E ROM. There is not any guide for TRIM within the RST-E version of the ROM while RAID is enabled and the RST-E driver version is less than 3.eight.[25] It is possible to feature an RST ROM to the BIOS to allow TRIM passthrough in RAID mode by means of the use of the RST ROM and driver.[24]
The most recent Option ROM version is a thirteen collection ROM, this ROM will now not be used by motherboard producers for the X79 chipset BIOS, and it may be injected right into a BIOS to use at the X79 with modded code, for the ones MFG's who have added a ROM switch, this is where the MFG has added both RST and RSTe to the RAID alternative of a BIOS, but there needs to be a code introduced for TRIM commands to be despatched, whilst you inject the RST and update the RSTe with RST option ROM in X79 forums that don't incorporate the ROM switch, TRIM may be dysfunctional.
There are modded RST 13 series Option ROMs (legacy) to be had at sure BIOS modding websites that have been made useful to be used in the X79 chipsets.
When booting in a BIOS surroundings (legacy) and some / EFI, the RST choice ROM is used. When booting in a true UEFI environment the Option ROM isn't used as a SataDriver with the RST model takes over. In BIOS mode the legacy/BIOS booting is below CSMCORE. In real UEFI mode the RST is controlled under SataDriver in BIOS.
The Intel RAID ROM is the firmware within the motherboard BIOS that is used to create the RAID array.
