RAID Failures In the past decade, most businesses have turned from single hard disk data storage to high speed multiple hard disks storage systems such as RAID (Redundant Array of Independent Disk). RAID systems are configured both to increase data performance and safeguard mission-critical applications. It combines multiple disks into a single logical unit in two ways:
The most common RAID configurations are: RAID0, RAID1 and RAID5. Some hardware RAIDs may also use more complex and expensive RAID controllers which support RAID6, RAID5E, RAID5EE and so on. Because of the strong promotional emphasis on the fault tolerance and auto-rebuild functions of RAIDs, users often have the perception that RAIDs will never fail. Thus, up-to-date data backups may not have been taken when users find their server has failed. To the surprise of many, RAIDs could and often did fail. The individual magnetic storage media in RAID systems suffer from the same types of failures as do conventional hard drives in personal computers and workstations. As the complexity of many server operation systems increases, this may result in additional data loss situations: Software Failures
Hardware Failures
Though raid disk arrays offer increased redundancy, capacity and performance over standard disk systems, once failed, they are often complex and more difficult to recover. It may be far from a trivial task for a user to recover the data on their own as even the most experienced system engineers who are familiar with standard RAID configurations, may lack the necessary skill sets to rescue a corrupted or inaccessible RAID volume. However, by using the RAID Scope application, the chance for vital data to be recovered will be greatly improved. In all the RAID failure scenarios mentioned above, the system configuration must be discovered and restored in order to read and extract data files such as documents and databases etc. Our technicians will capture specific information about the RAID system i.e. the operating system, hardware configuration, failure type and will transfer the corrupt system files for analysis by our technical support department to ascertain the specific configuration needed to rebuild the data. RAIDScope gives the user access to highly skilled RAID engineers who are able to recover data from all types of server configurations including RAID 5/5E/5EE, RAID 0, RAID 1, RAID10, RAID 6 and from all operating systems. |
