What is RAID?

RAID is short for Redundant Array of Independent Disks. In the beginning, these were called Inexpensive Disk Arrays. It is a technology that allows for enhanced storage capacity through redundancy by combining several low-cost hard drives into one logical device.

raid data recovery what is raid cbl tech sg

All of the drives in the array are interdependent on one another, therefore this makes the array more reliable overall. Though RAID storage is very effective at storing data with a level of fail-safes in the technology, RAID is not perfect and therefore there is always a risk of losing some of your files and data. A RAID Data array literally refers to a cluster of multiple hard disk drives which are bundled together to form one logical drive.

Using RAID can improve the speed at which data is accessed and written, while simultaneously elevating the level of safety afforded to the data that is stored. Redundancy means having two copies of everything so if one copy goes down, there’s another one ready to take its place. Many different RAID Data Server Array level configurations have been developed, including some nested ones.

Originally there were 5 RAID Data Server Array level types, but many more variations exist today, including some nested and others, not standardized by any organization. There are RAID Data Array Systems that range from RAID 0 to RAID 100.

So, what does the RAID level actually tell us about the array?

Well, the number refers to the type of RAID used. For instance, RAID 0 means no redundancy at all, so you can lose everything without losing any data. A RAID 1 would be mirrored, meaning that every writer goes to two places simultaneously. A RAID 5 would be striped across multiple disks, giving you better performance than a single disk.

RAID System Overview

The RAID System was developed with two main goals in mind: to increase the reliability of stored files and to improve the speed at which they could be accessed.

A RAID array combines many disk drives into one logical system through specialized hardware or software to have a safer place to store data. Hardware-based RAIDs may be integrated directly into the motherboard or they may be added in expansion slots. They are commonly used in server environments where high reliability is needed. In contrast, software-based RAIDs are often found in personal computers (PC) and workstations. These systems are also known as “RAID 0” because each drive contains an equal amount of data.

3 Functions within a RAID Setup

  • Mirroring: The copying of data from one drive to another.
  • Striping: The splitting of large amounts of data across multiple disks.
  • Error Correction: Where redundant data is stored to allow problems to be detected and possibly fixed also known as fault tolerance

Due to the complexity of the way a RAID server can be set up, one function or all functions may be utilized to run the RAID system smoothly.

The purpose of RAID

RAID is used in server systems, but can also be used on desktop workstations. It is especially useful in computer systems that store large amounts of data, such as video and audio editors.

the purpose of raid server array cbl sg

In order to improve performance, ensure data security, and provide the array system the ability to scale as a whole, RAID data array systems were designed to operate as a single logical unit and function together as a cohesive unit. The results were a unique redundancy scheme that offered high levels of fault tolerance and the ability to read and write even when one of the disks failed. RAID data controllers have the capacity to keep reading and writing data even after the hard disks have been removed from the online service.

Understanding Technical RAID Terms

RAID: An array-based technology that allows multiple hard disks to be used together to provide increased storage capacity and improved performance. It uses redundancy to protect against drive failure.

NAS: Network Attached Solutions Devices (NAS) acts as a personal cloud for a business where information is stored securely and easily among users. Like a RAID server, NAS uses a RAID configuration for redundancy and increased speed. However, unlike a RAID server that is connected directly to the computer, it will naturally be slower than a standard RAID system array

SAN: Storage Area Network (SAN) is a dedicated, high-performance storage system that provides block-level transfer of data between servers and storage devices. A SAN is a networked storage device that allows computers to share files directly with Direct Attached Storage (DAS) speeds. It combines the speed of direct access with the reliability of shared access.

DAS: Direct attached storage (DAS) is similar to an external hard disk except that it connects directly to a computer via a cable instead of using removable media. It may use any type of connection, including ATA, SATA, SCSI, SAS, USB, FireWire, eSATA, or Thunderbolt.

Parity: Hard drives that are utilized in a RAID array to provide fault tolerance are referred to as parity drives.

Mirroring: Disk mirroring, commonly known as RAID 1, replicates data over two or more disks.

Striping: Disk striping is a technique that is utilized in RAID level 0 and enables the system to write data across numerous hard drives rather than only in a single drive. Partitions are created on each and every storage drive using this procedure.

Byte: Byte-level striping means that each file is split up into parts of one byte in size.

Block: Each file is divided into pieces that are one block in size. The default size for a block is 512 bytes, however, the size can be changed if desired. The stripe size is a term that’s typically used to refer to the size of this block.

Left / Right Symmetry: The symmetry in a RAID controls how the data and parity are distributed across the drives. There are four main styles of distribution, left asymmetric, left symmetric, right asymmetric, and right symmetric, and which one is used is dependent on the RAID. Some companies make custom array systems based on what is required in the business.

Hot Spare: When a primary component breaks, a hot spare, which is also known as a hot standby, is a backup component that can be rapidly put into service.

Degraded mode: A word that describes the condition of a RAID array system when it is operational despite the presence of one or more failed disks in its system.

Optimal mode: A status that can be assigned to a RAID array system to indicate that it is functioning appropriately and free of errors when it is in Optimal Mode.

Common RAID System Setups

RAID LevelDescription
RAID 0A RAID 0 is the classic striping configu­ration, where data is written to all drives at once. However, this performance comes with a risk, if one drive fails, then a serious loss could occur.

If drive 2 failed and the second stripe was lost, a file that was made to use data stripes 1 through 4 would likely become corrupted.
RAID 1This is the RAID configuration that sets up a mirrored set of disks. It has no performance benefits, but if one drive goes down, you’ll be able to recover from it using the other.
RAID 2RAID 2 is comprised of data striping at the bit-by-bit (or byte) levels with a dedicated parity disk. It was originally designed for hard disks that did not have built-in ECC (error correction code). Because of this, RAID 2 is rarely used today.
RAID 3RAID 3 stripe data at the byte and the blocks respectively. RAID 3 is rarely used today because of its poor performance when using byte-stripe stripers.
RAID 4RAID 4 is better than RAID 3 when using a striped array, however, it still has slow write speeds due to the need for updating the parity on each write.
RAID 5RAID 5 is generally regarded as offering the best of both worlds – reliability and flexibility at a reasonable cost. It works by dividing the data into chunks (called stripes) across multiple drives, then adding an extra drive for redundancy. Parity information is added to each stripe, which means that if any single disk fails, the data can be recovered from the remaining ones.

Because in RAID 5 it distributes to both the right and the left, determining the direction of parity is simple.

Asymmetric RAIDs skip parity blocks when writing new files, but once they encounter a parity block, they shift laterally and descend into the next stripe sets in symmetric RAIDs (RAID 1). Once the data encounters a parity block, it shifts laterally and descends to the next stripe set in symmetric RAIDs.
RAID 6A RAID 6 system is an expansion of a RAID 5 system. It uses the same method of distributing and dividing up the files, but adds another file to distribute across the remaining available space. This means that even if two hard drives failed at once, the RAID would not lose any of its stored files. However, in smaller RAIDs, the chances of two hard drives failing at once are lower, but as the number of hard drives increase, the likelihood of simultaneous failure rises.

For write speeds, RAID 6 is very similar to RAID 5; however, for read speeds, RAID 6 is slower than RAID 5.
RAID 0+1Standard RAID levels can be combined to create hybrid or nested RAID levels to increase performance and/or redundancy. RAID types that provide redundancy are typically combined with RAID 0 to increase performance.

RAID 01, also known as RAID 0+1, is a RAID level that uses a mirror of stripes to both copy and share data across disks. The usable capacity of a RAID 01 array is the same as that of a RAID 1 array made of the same drives, where half of the drives are used to mirror the other half.

A conventional RAID 01 arrangement has to have at least four disks in order to function, however greater array sizes are also common.
RAID 10 (RAID 1+0)RAID 10, also known as RAID 1+0 or RAID 1&0, is similar to RAID 01 except that the two used standard RAID levels are layered in the opposite order; thus, RAID 10 is a stripe of mirrors.

A big advantage of this is if a disk fails, its replacement doesn’t affect the operation of the remaining disks. But if that disk fails and isn’t replaced, then all the disks become unusable—if that happens, they lose all their stored information.

You could use RAID 5 as an example here, by stacking multiple drives (RAID 0) into a single disk array (RAID 1), and then doing the same thing again (to create RAID 2). However, you could also use other configurations, such as RAID 3, which combines two mirrored disks, or RAID 6, where six drives are combined to form three independent redundancy groups.
RAID 50 (RAID 5+0)A RAID 50 array includes both the stripe size of RAID 0 and the redundancy of RAID 5. It uses 6 disks. If any disk fails, there would be no data lost. However, if 3 disks failed, then 1 disk from each of the 3 RAID 5 arrays would need to be replaced.

To ensure reliable operation, RAID arrays often include spare drives that can be used to replace failed ones quickly.
RAID 60 (RAID 6+0)RAID 60, also known as RAID 6+0, is an advanced form of RAID 0 which combines the straight block-based stripe of RAID 0 with the mirrored redundancy of RAID 6. It requires at least 8 hard drives.
RAID 100 (RAID 10+0)A RAID 100 is a stripe of RAID10 arrays. It is logically equivalent to a wide RAID 10, but is usually implemented by software RAID 0 over hardwared RAID 10. Being striped two ways, it is often referred to as a “plaid RAID”.

6 Possibilities of RAID Data Loss

Single And Multi Drive Issues

RAID Data systems are designed to be able to handle individual disk failures, but when a RAID Data system fails, the workload of the surviving disks increases, which leads to increased risks of further disk failures. If we fail to detect these issues early enough, we may not be able to fix them before they become catastrophic. CBL Data Recovery has teams of professional RAID Data Recovery experts that are able to recover your data from faulty or corrupted disks and able to rebuild your file systems from fully failed to partially restore RAID Data systems

Power Issues

RAID systems can be adversely affected by sudden interruptions in electrical supply, which may result in lost data. RAID systems running in a degraded mode are particularly susceptible to such disruptions because they allow for the incorporation of new disks without having to wait for them to synchronize. In the event of a blackout or a building power trip, it is wise to have a separate electrical unit that will be powering your RAID system array.

Here at CBL Data Recovery, we are equipped with the knowledge and also industry standard equipment to perform your data recovery quickly, securely, and seamlessly. Contact a RAID Data Recovery Expert.

Natural Disasters

If a RAID system is destroyed by fire, flood, earthquake, or any other natural event, rebuilding the RAID requires special equipment, expertise, and know-how to decontaminate and rebuild the drive array. Ontrack has state of industry tools and clean room environments to safely recover from physical damage.

Human Errors

Regardless of whether by accident or intention, losing files due to reformatting, re-installing, or overwrit­ing can happen to any company of any size, no matter how experienced they may be with similar situations. Our CBL Data Recovery RAID server data recovery experts equipped with industry-standard technology can overcome even the most damaging errors.

Cyber Attacks

Cyber attacks unlike ransomware attacks are unwanted attempts to steal, expose and/or destroy sensitive customer and employee records caused by unauthorized access to computers and their networks. This lead to significant losses in terms of both time and money for your business. CBL Data Recovery experts can help you safely recover your data from malicious cyber attacks

Ransomware Attacks

Malicious software that encrypts a victim’s data prevents them from accessing their computers, or any data stored thereon. Locking important user data up so they cannot be accessed by anyone until a ransom is paid. A ransomware attack or denial of service (DoS) attack can cause the computer itself to be locked, or the data stored on it to be deleted, encrypted, or corrupted. If you’re hit by a ransomware attack, our CBL Data Recovery RAID server data recovery experts can help you in your situation.

What are the signs of RAID failure?

A RAID server array failure is one of the most common problems faced by IT professionals. A RAID array is a redundant storage system used to protect data against hardware failure.

signs of raid failure raid data recovery scbl tech sg

When you lose power to your computer controlling the RAID system, it automatically restarts and checks whether there are any errors in the hard disk drives. If there are no errors, it continues to work normally. However, if there is an error, the system stops working. Below are typical signs of a RAID failure:-

The noticeable signs of a RAID failure :

  • Alarm and beep sounds
  • Error messages appear
  • Noise coming from RAID hard disk drives
  • The red light on hard disk drives attached to the RAID lights up

The less noticeable signs of a RAID failure :

  • RAID Array / Controller Card Malfunction
  • Failure to boot
  • Registry Configuration in Server Is Lost
  • RAID Container Crash
  • Missing Files
  • Deleted Files and Data
  • Data & Database Corruption
  • Unable to Access Files
  • Logical Drives Disappearing
  • Lost Connection to RAID Server, Volume, Logical Unit Number (LUN)
  • Specific Volume Failure
  • System Speed
  • Inaccessible System
  • Multiple Hard Disk Drives Failing at the Same Time
  • Conflicts of Incompatible Hardware
  • Software & Operating System Updates
  • Corrupted RAID Management Software
  • Corrupted Software
  • Intermittent Failing of Hard Disk Drives
  • Failure of Array Rebuild
  • Damaged Striping
  • Array / Volumes That Won’t Mount After a Server Crash

How to Fix a Raid Array That Has Failed?

If you experience a RAID failure, first check for physical damage to your disks. Next, try to determine whether the problem was caused by hardware or software issues. If the issue is related to the operating system, then you should contact your vendor. Finally, if the issue is still not resolved after contacting your vendor, do not hesitate to contact CBL RAID Server Data Recovery Experts.

Running the wrong data recovery plan might leave your RAID array system damaged. It is necessary to collect as much information before performing a data recovery plan.

For the best opportunity to recover the lost data, it is essential to find out:-

  1. What happened during the time just before the RAID failure happened?
  2. Which data is crucial for the progress of your business?
  3. Is there another way of obtaining a backup of this data?

For emergencies please contact our experienced RAID Server Data Recovery Experts.

6 RAID System Array Care Tips

  1. If you replace a failing hard disk with another that was previously part of an array, be sure to completely wipe out the new disk before using it
  2. If a drive in your RAID array starts making unusual sounds like screeching or beeping, stop using it immediately as it may damage other parts of the array system, and contact a professional for assistance.
  3. Restoring files from a backup image can also lead to irreparable loss of data. Therefore, before attempting to recover lost data, make sure that you have made another backup of your data.
  4. Running defragmentation programs on disks that you suspect have failed may corrupt and damage the whole hard disk drive.
  5. If you’re running a RAID array, don’t run any volume recovery software during a blackout. Doing so could cause damage to the array.
  6. Attach RAID servers to backup power generators in the event you experience a power trip or a building-wide blackout, your RAID array system will not be affected for the time during the power loss.
