Don't panic! Chances are if you are reading this you have a failed RAID array, well you have come to the right place. Xytron routinely recovers data from failed RAID arrays, however it has failed, we have solutions for you. 

Typical RAID server data failure symptoms 

Error messages you may experience with a failed RAID server

  • Failed one or more drives
  • Offline
  • Bad
  • RAID error

Xytron have recovered server Raid arrays from a few Gigabytes to terabytes, 2 hard drives to multiple hard drives. 

Please choose carefully your Raid server data recovery partner, as often rebuilding the array, or data retrieval software can render the data unrecoverable, we have developed techniques to enable the recovery of your precious / important data, do not amend your array unless you are an expert, or the data has no value to you. 

Raid systems can and do fail, often with devastating results, this is compounded as no backup system have been implemented. Xytron can recover from all RAID server configurations, here is a basic description of the most popular levels. 


Why does RAID fail? 

RAID systems can fail due to the following reasons
Power failures or power cycling
Mechanical or physical failure
Firmware or microcode failure
Malicious and or virus damage
Burnt or liquid damage

Our Raid server data recovery solutions have a no data no fee policy, so in the unlikely event that the data is unrecoverable you would pay nothing, we get paid for results.

  • Level 0 -- Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple hard drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.

  • Level 1 -- Mirroring and Duplexing: Provides drive mirroring. Level 1 provides twice the read transaction rate of single hard drive and the same write transaction rate as single disks. This offers this best RAID server data recovery.

  • Level 2 -- Error-Correcting : Not a typical implementation and rarely used, Level 2 stripes data at the bit level rather than the block level.

    Level 3 -- Bit-Interleaved Parity: Provides byte-lev el striping with a dedicated parity disk. Level 3, which cannot service simultaneous multiple requests, also is rarely used.

  • Level 4 -- Dedicated Parity Drive: A commonly used implementation of RAID, Level 4 provides block-level striping (like Level 0) with a parity disk. If a data disk fails, the parity data is used to create a replacement disk. A disadvantage to Level 4 is that the parity disk can create write bottlenecks.

  • Level 5 -- Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID. Raid server data recovery at this level is often very successful due to the configuration.

  • Level 6 -- Independent Data Disks with Double Parity: Provides block-level striping with parity data distributed across all disks.

  • Level 0+1 - A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.

  • Level 10 - A Stripe of Mirrors: Not one of the original RAID levels, multiple RAID 1 mirrors are created, and a RAID 0 stripe is created over these.

  • Level 7: A trademark of Storage Computer Corporation that adds caching to Levels 3 or 4.

  • RAID S : EMC Corporation's proprietary striped parity RAID system used in its Symmetrix storage systems.

Server RAID data recovery requires that the original computer system and RAID controller card be supplied as rebuilding the array may fail if incorrect components are used in the recovery. Please contact us today for a Raid data recovery solution or email raid@xytron.co.uk
