Widely available Intel Matrix RAID / Intel Rapid Storage Technology, embedded in Intel server motherboards and modern desktop motherboards, is a pseudo-hardware controller, not a true hardware RAID controller.
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. Set up of the RAID volumes must be done by using the ROM option in the Matrix Storage Manager, then further configuration can be done in DM-RAID or MD-RAID. [10]
Under traditional RAID, an entire disk storage system of, say, 100 disks would be split into multiple arrays each of, say, 10 disks. By contrast, under declustered RAID, the entire storage system is used to make one array. Every data item is written twice, as in mirroring, but logically adjacent data and copies are spread arbitrarily.
Data scrubbing reduces the likelihood that single correctable errors will accumulate, leading to reduced risks of uncorrectable errors. Data integrity is a high-priority concern in writing, reading, storage, transmission, or processing of data in computer operating systems and in computer storage and data transmission systems.
For a short time in March 2010, users were led to believe that the Intel Rapid Storage Technology (RST) 9.6 (and later) drivers in Windows 7 supported TRIM on RAID volumes, but Intel later clarified that TRIM was supported for the BIOS settings of AHCI mode and RAID mode, but not if the drive was part of a RAID volume.
An image of this initial root file system (along with the kernel image) must be stored somewhere accessible by the Linux bootloader or the boot firmware of the computer. This can be the root file system itself, a boot image on an optical disc , a small partition on a local disk (a boot partition , usually using ext2 or FAT file systems), or a ...
In computer data storage, Smart Response Technology (SRT, also called SSD Caching before it was launched) is a proprietary caching mechanism introduced in 2011 by Intel for their Z68 chipset (for the Sandy Bridge–series processors), which allows a SATA solid-state drive (SSD) to function as cache for a (conventional, magnetic) hard disk drive (HDD).
The word "medium" refers to the physical storage layer, the medium on which the data is stored; as opposed to errors related to e.g. protocol, device/controller/driver state, etc. Medium errors are most commonly detected by checking the read data against a checksum – itself being most commonly also stored on the same device.
