Many businesses that have data requirements not met by using NAS technology will use a Dell RAID (PERC – PowerEdge RAID Controller) server for their needs. Dell servers are typically of a higher specification than most NAS devices in terms of memory, processing power and capabilities. Like most other RAID problems, faults involving data loss on Dell RAID equipment is best handled by a skilled Dell RAID data recovery company such as Data Clinic. Dell servers frequently use RAID 5 setups but also popular are RAID 6, RAID 10 and RAID 50. Data recovery from damaged Dell RAID and server arrays is a specialised discipline and needs to be done correctly the first time otherwise the data is often ruined.
Dell servers are frequently the workhorses of modern businesses and organisations. As such the data they contain is often vital and central to the role of the organisation and it’s day to day operation. Because the data RAIDs and servers contain is often critical, companies with failed Dell servers and RAID systems will often want their data recovered as quickly as possible.
In statistics provided by Data Clinic, these are the top 8 reasons for data loss on Dell RAID servers:
- Accidental File & Folder Deletion
- Failure of one or more of the hard drives in the RAID set
- Hard Drive Head Crashes
- System Infection by a Virus or Malware
- Hard Drives with the ‘Click of Death’
- Server Crashes with a Blue Screen
- Physical Damage From Fire or Flood
- Software Corruption
It’s important that you carefully assess the value of the data on your damaged Dell RAID server. If the lost data is of any value it’s important that you use a specialist data recovery company to repair the problem and recover the data. RAID data recovery from Dell servers is not like recovering data from standalone single hard drives. The data held on a RAID is spread across all the drives that make up the RAID set – so for example if there are 8 drives that make up the RAID a document is spread across all the drives and is not saved to just one drive. It’s therefore imperative that the data recovery process is completed correctly and by skilled individuals who are experienced in recovering data from failed Dell systems.
Do’s and Don’ts
- Don’t change order of the disks in the array
- Don’t rebuild the array
- Don’t run any recovery software like FSCK, CHKDSK, SCANDISK or 3rd party software.
All the above actions should be avoided as they are easily capable of damaging the data further, making it unrecoverable.
As Dell RAID data recovery experts, Data Clinic’s recovery services use bespoke procedures, and custom hardware and software to ensure they get the very best recovery of data from your failed server.
Data Clinic’s Dell RAID and server support is UK wide and operates on a 24/7 basis. Data can be recovered overnight, over the weekend or on a non emergency basis.
