Although failures would rise in proportion to the number of drives, by configuring for redundancy, the reliability of an array could far exceed that of any large single drive.

Although not yet using that terminology, the technologies of the five levels of RAID named in the June paper were used in various products prior to the paper's publication, [3] including the following:.

Many RAID levels employ an error protection scheme called " parity ", a widely used method in information technology to provide fault tolerance in a given set of data.

For example, a fast SSD can be mirrored with a mechanical drive. For this configuration to provide a significant speed advantage an appropriate controller is needed that uses the fast SSD for all read operations.

Adaptec calls this "hybrid RAID". A number of standard schemes have evolved. These are called levels. Originally, there were five RAID levels, but many variations have evolved, notably several nested levels and many non-standard levels mostly proprietary.

The elements of a RAID may be either individual drives or arrays themselves. Arrays are rarely nested more than one level deep.

The final array is known as the top array. Many configurations other than the basic numbered RAID levels are possible, and many companies, organizations, and groups have created their own non-standard configurations, in many cases designed to meet the specialized needs of a small niche group.

Such configurations include the following:. The distribution of data across multiple drives can be managed either by dedicated computer hardware or by software.

A software solution may be part of the operating system, part of the firmware and drivers supplied with a standard drive controller so-called "hardware-assisted software RAID" , or it may reside entirely within the hardware RAID controller.

Software RAID implementations are provided by many modern operating systems. Software RAID can be implemented as:.

Some advanced file systems are designed to organize data across multiple storage devices directly, without needing the help of a third-party logical volume manager:.

If a boot drive fails, the system has to be sophisticated enough to be able to boot from the remaining drive or drives.

The second-stage boot loader for FreeBSD is capable of loading a kernel from such an array. Software-implemented RAID is not always compatible with the system's boot process, and it is generally impractical for desktop versions of Windows.

However, hardware RAID controllers are expensive and proprietary. To fill this gap, inexpensive "RAID controllers" were introduced that do not contain a dedicated RAID controller chip, but simply a standard drive controller chip with proprietary firmware and drivers.

During early bootup, the RAID is implemented by the firmware and, once the operating system has been more completely loaded, the drivers take over control.

Consequently, such controllers may not work when driver support is not available for the host operating system. An advantage of this model over the pure software RAID is that—if using a redundancy mode—the boot drive is protected from failure due to the firmware during the boot process even before the operating systems drivers take over.

Data scrubbing referred to in some environments as patrol read involves periodic reading and checking by the RAID controller of all the blocks in an array, including those not otherwise accessed.

This detects bad blocks before use. Frequently, a RAID controller is configured to "drop" a component drive that is, to assume a component drive has failed if the drive has been unresponsive for eight seconds or so; this might cause the array controller to drop a good drive because that drive has not been given enough time to complete its internal error recovery procedure.

Consequently, using RAID for consumer-marketed drives can be risky, and so-called "enterprise class" drives limit this error recovery time to reduce risk.

The utility enabled TLER time limited error recovery , which limits the error recovery time to seven seconds. Around September , Western Digital disabled this feature in their desktop drives e.

Similar technologies are used by Seagate, Samsung, and Hitachi. For non-RAID usage, an enterprise class drive with a short error recovery timeout that cannot be changed is therefore less suitable than a desktop drive.

Muhammad ibn Maslamah pretended to be dead. A Muslim who happened to pass that way found him and assisted him to return to Medina.

The raid was unsuccessful. Small scale raiding warfare was common in Western European warfare of the Middle Ages. Much of a professional soldiers' time could be spent in "little war", carrying out raids or defending against them.

This last is notable not just for its success and scope but the fact that the raiders deliberately captured records in order to carry out a post-operational analysis of the impact of the raid on the enemy economy.

The largest raids in history were the series undertaken during and following the Mongol invasion of Central Asia.

In the operational level of war , raids were the precursors in the development of the Operational Manoeuvre Groups in the Soviet Army as early as the s.

Raiding by sea was known at the time of the Pharaohs , when the shipborne forces of the Sea Peoples caused serious disruption to the economies of the eastern Mediterranean.

In the early Middle Ages , Viking raiders from Scandinavia attacked the British isles , France and Spain , attacking coastal and riverside targets.

Much Viking raiding was carried out as a private initiative with a few ships, usually to gain loot, but much larger fleets were also involved, often as intent on extorting protection money English: Danegeld as looting and pillaging.

It remained a common element of the medieval naval warfare. A major raid on Cadiz to destroy shipping being assembled for the Spanish Armada was carried out by Sir Francis Drake in In need of language advice?

In practice, the drives are often the same age with similar wear and subject to the same environment. Since many drive failures are due to mechanical issues which are more likely on older drives , this violates the assumptions of independent, identical rate of failure amongst drives; failures are in fact statistically correlated.

In a study of about , drives, the probability of two drives in the same cluster failing within one hour was four times larger than predicted by the exponential statistical distribution —which characterizes processes in which events occur continuously and independently at a constant average rate.

The probability of two failures in the same hour period was twice as large as predicted by an exponential distribution. The recovery of UREs involves remapping of affected underlying disk sectors, utilizing the drive's sector remapping pool; in case of UREs detected during background scrubbing, data redundancy provided by a fully operational RAID set allows the missing data to be reconstructed and rewritten to a remapped sector.

Drive capacity has grown at a much faster rate than transfer speed, and error rates have only fallen a little in comparison.

Therefore, larger-capacity drives may take hours if not days to rebuild, during which time other drives may fail or yet undetected read errors may surface.

The rebuild time is also limited if the entire array is still in operation at reduced capacity. Even though individual drives' mean time between failure MTBF have increased over time, this increase has not kept pace with the increased storage capacity of the drives.

The time to rebuild the array after a single drive failure, as well as the chance of a second failure during a rebuild, have increased over time. Triple parity schemes, or triple mirroring, have been suggested as one approach to improve resilience to an additional drive failure during this large rebuild time.

A system crash or other interruption of a write operation can result in states where the parity is inconsistent with the data due to non-atomicity of the write process, such that the parity cannot be used for recovery in the case of a disk failure the so-called RAID 5 write hole.

Recently mdadm fixed it by introducing a dedicated journaling device to avoid performance penalty, typically, SSDs and NVMs are preferred for that purpose.

This is a little understood and rarely mentioned failure mode for redundant storage systems that do not utilize transactional features. Database researcher Jim Gray wrote "Update in Place is a Poison Apple" during the early days of relational database commercialization.

There are concerns about write-cache reliability, specifically regarding devices equipped with a write-back cache , which is a caching system that reports the data as written as soon as it is written to cache, as opposed to when it is written to the non-volatile medium.

If the system experiences a power loss or other major failure, the data may be irrevocably lost from the cache before reaching the non-volatile storage.

For this reason good write-back cache implementations include mechanisms, such as redundant battery power, to preserve cache contents across system failures including power failures and to flush the cache at system restart time.

Retrieved November 18, Patterson recalled the beginnings of his RAID project in Patterson leads a team that defines RAID standards for improved performance, reliability and scalability.

We were not the first to think of the idea of replacing what Patterson described as a slow large expensive disk SLED with an array of inexpensive disks.

For example, the concept of disk mirroring, pioneered by Tandem, was well known, and some storage products had already been constructed around arrays of small disks.

Since a large number of bits are handled in parallel, it is practical to use error checking and correction ECC bits, and each 39 bit byte is composed of 32 data bits and seven ECC bits.

The ECC bits accompany all data transferred to or from the high-speed disks, and, on reading, are used to correct a single bit error in a byte and detect double and most multiple errors in a byte.
