These are called levels. Originally, there were five RAID levels, but many variations have evolved, including 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.

Hardware RAID controllers can be configured through card BIOS before an operating system is booted, and after the operating system is booted, proprietary configuration utilities are available from the manufacturer of each controller.

Unlike the network interface controllers for Ethernet , which can usually be configured and serviced entirely through the common operating system paradigms like ifconfig in Unix , without a need for any third-party tools, each manufacturer of each RAID controller usually provides their own proprietary software tooling for each operating system that they deem to support, ensuring a vendor lock-in , and contributing to reliability issues.

For example, in FreeBSD , in order to access the configuration of Adaptec RAID controllers, users are required to enable Linux compatibility layer , and use the Linux tooling from Adaptec, [35] potentially compromising the stability, reliability and security of their setup, especially when taking the long term view.

Some other operating systems have implemented their own generic frameworks for interfacing with any RAID controller, and provide tools for monitoring RAID volume status, as well as facilitation of drive identification through LED blinking, alarm management and hot spare disk designations from within the operating system without having to reboot into card BIOS.

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 consumer-marketed drives with RAID 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.

While RAID may protect against physical drive failure, the data is still exposed to operator, software, hardware, and virus destruction.

Many studies cite operator fault as a common source of malfunction, [75] [76] such as a server operator replacing the incorrect drive in a faulty RAID, and disabling the system even temporarily in the process.

An array can be overwhelmed by catastrophic failure that exceeds its recovery capacity and the entire array is at risk of physical damage by fire, natural disaster, and human forces, however backups can be stored off site.

An array is also vulnerable to controller failure because it is not always possible to migrate it to a new, different controller without data loss.

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.

Permite tasas de transferencias extremadamente altas. Esto quiere decir que si por ejemplo perdemos un byte de uno de los discos, siempre podremos recuperarlo mediante el byte de paridad que se ha generado anteriormente.

El RAID 5 ha logrado popularidad gracias a su bajo coste de redundancia. Un bloque se compone a menudo de muchos sectores consecutivos de disco.

Sin embargo, los bloques de paridad se leen cuando la lectura de un sector de datos provoca un error de CRC. Estos discos pueden estar conectados y preparados hot spare o en espera standby spare.

Un disco de reserva no es realmente parte del conjunto hasta que un disco falla y el conjunto se reconstruye sobre el de reserva.

Como puede verse en el diagrama, primero se crean dos conjuntos RAID 0 dividiendo los datos en discos y luego, sobre los anteriores, se crea un conjunto RAID 1 realizando un espejo de los anteriores.

Con la cada vez mayor capacidad de las unidades de discos liderada por las unidades serial ATA , el riesgo de fallo de los discos es cada vez mayor.

Un disco de cada conjunto RAID 5 puede fallar sin que se pierdan datos. Si uno falla, todos los datos del conjunto global se pierden.

El tiempo necesario para recuperar detectar y responder al fallo de disco y reconstruir el conjunto sobre el nuevo disco representa un periodo de vulnerabilidad del conjunto RAID.
