Critical  RAID Server Failure Outage RAID Data Recovery Services

 When an organization's RAID server enterprise storage system fails, it can be the first scene in an unfolding nightmare. The damage and data losses caused by such a failure are not only disruptive to productivity but financial losses incurred to a company can be astronomical.

If such a data disaster is not immediately managed by an expert RAID Data recovery professional, data loss can become permanent. SalvageData's RAID data recovery team is experienced and skilled at handling the most difficult of RAID recovery scenarios.

With past success for trusted customers such as NASA, NYU and the U.S. government, SalvageData has successfully tackled and resolved the most complex RAID failures known to occur. This valuable experience gained by our company has established a level of competency in this area difficult to match, even by prominent competitors. Because our own lab environment employs many separate hard drive configurations and file systems on several different computers and RAID arrays, our team of professionals remain  as to the latest NAS, SAN and Server RAID tools and data recovery strategies.

There are a litany of reasons that cause a RAID system failure. Sometimes it's human error, a power fluctuation error, software or hardware problems. It's also common for failures to result from a disk or controller, triggered by a power failure or surge. If not addressed quickly and expertly, this can lead to a disruption of logical volumes, which very often destroys the file system structure, as well as its data.

That's why it is critical for you to contact SalvageData's professionals immediately if you have experience a RAID array failure. They will advise you on how to proceed. Our RAID engineers will walk you through the process of submitting a case, making sure you fully recover your mission-critical data.

 SalvageData supports and performs data recovery for all RAID server makes and types, including the most widely used RAID 0, RAID 1 and RAID 5 configurations.

	RAID Types and Varying Configurations

The different types of supported RAID configurations are:

RAID 0

RAID O uses what is called a data striping technique. Multiple hard drives are combined into one large volume. Because it splits the data and accesses both drives in parallel, RAID O reads and writes faster than a non-RAID configuration. RAID 0 doesn't offer data redundancy and requires a minimum of two hard drives to be totally restored as a requirement for completing a successful RAID recovery.

RAID 1

RAID 1 mirrors, or copies the content of one drive onto another twin drive. If one of your drives should fail, mirroring guarantees optimal data integrity and instant access to your data. Another advantage of RAID 1 is that it allows you to use just 50 percent of your NAS device's available capacity. A requirement for RAID 1 is a minimum of two hard drives and when using more they must be even numbers. The advantage of this type of RAID configuration is that recovery takes less time, resources and tools - assuming that the mirrors functioning correctly when the failure occurred.

RAID 5

RAID 5 offers the best mix of data backup, capacity and performance. Although RAID 5 does stripe all available drives into a single large volume, space equal to one of its hard drives is used to store parity data. If correctly configured, when one hard drive fails, it will use the parity data to rebuild your data. RAID needs a minimum of 3 hard drives. Another backup option RAID 5 offers is hot spare. This reserves an additional hard drive that takes over immediately if another drive fails. Total RAID capacity is calculated by subtracting the space of two drives from the sum of all the hard drives. If you want to use hot spare with RAID 5, you must have a minimum of 4 hard drives. In order for us to perform a successful RAID recovery, we need all of the drives that are part of the array.

Non-RAID

A RAID configuration is not necessary in order to configure your server. However, such non-RAID configurations, which are often referred to as JBOD (Just a Bunch Of Disks), offer no data redundancy and are generally slower than RAID configurations. Recovering data from a non-RAID configuration can vary in complexity based on its hardware configuration.

	The RAID Recovery Experts for All Platforms and Configurations

SalvageData's team of recovery technicians and engineers pride themselves on being proficient with the latest hardware platforms, in addition to the most used legacy systems. Often we only require the drives, controller and storage devices in order to perform a RAID recovery. We treat every RAID data recovery project sent to our lab as a high priority because we understand how important the lost data is to your organization. We are expertly qualified to service all the following hardware and server RAID manufacturers listed below. Nonetheless, please call us any time if you have questions about any specific RAID configuration or data recovery. 

Using advanced data recovery methods we can safely and securely restore your business-critical data and mission-critical files from the following types of data media failure and situations: 

• RAID controller failure
• Rebuild failure
• Damaged striping
• Multiple drive failure (or multiple drives go offline)
• RAID array or volumes that won't mount after a server crash
• Configuration damage or corruption
• Addition of incompatible drives
• Hardware conflicts
• Software corruption
• Viruses or malicious intent
• Software or operating system upgrades
