Other RAID Levels
The most common implementations of RAID are RAID 0, 1 or 5. CDR also receives requests regularly for the recovery of RAID 10 and RAID 6 arrays. As disks have grown in capacity the implementation of RAID 50, or mixed RAID levels, are becoming increasingly common.
Proprietary RAID configurations
RAID 6 Arrays can be particularly challenging to recover data from. This is because many manufacturers use proprietary ‘block-maps’. A ‘block-map’ is the pattern in which data is distributed over the disks in the RAID array. Whilst Reed-Solomon and Double-XOR are standard RAID 6 implementations, a number of RAID controllers use a proprietary method. For these RAIDs it is necessary to establish the block-map l out, and then apply this within custom built software.
CDR – Manchester Data Recovery Services – has the capability to recover data from all types of RAID, including those using proprietary block-maps.
Hardware RAID levels CDR can recover data from
- RAID 0
- RAID 1
- RAID 3
- RAID 4
- RAID 5
- RAID 6
- RAID 0+1
- RAID 1+0
- RAID 100 (RAID 10+0)
- RAID 50 (RAID 5+0)
- RAID 53
- RAID 60 (RAID 6+0)
Custom RAID levels CDR can recover data from
- Double parity
- RAID 5E, RAID 5EE, and RAID 6E
- Intel Matrix RAID
- Linux MD RAID 10
- RAID 1E
- Drive Extender
- CRYPTO softraid
It is now rare to see RAID arrays configurated in RAID 2, 3 or 4. These were superseded several years ago by modern implementations, typically by RAID 5.
What services can CDR provide?
- Recover your lost data.
- Provide a disk image to allow an attempt to make the computer / server bootable.
- Advise on appropriate backup method.
- Provide a fixed price quotation in advance of receipt of any RAID array.
- Experienced staff with technical expertise can talk you through the process, including any early stage diagnosis before the RAID is received.
- Please phone 0161 408 4857 to discuss your data recovery.
