![]() No cache memory protection in the event of a power failure.OS reboot may not work with a failed disk.OS may still be crashed by a failed disk.Hot-swapping support is limited by OS and server model.Flexible, can be mixed with non-RAID partitions.To avoid this situation, a dedicated Battery Back-up Unit (BBU) can be attached to the controller to keep the contents of the cache memory available in the event of a power failure. Leaseweb offers RAID on all servers containing 2 or more disks - a hardware RAID if the server model features a hardware RAID controller, or else a software RAID. Server re-installations with software or hardware RAID are offered at no additional cost. If you wish to reinstall your server, and the desired RAID option is not available through our Customer Portal & API, you can request it via a support ticket. Patterson, Garth Gibson, Randy H.Re-create Deleted or Damaged Disk Array (RAID) Virtually Further readingĪrs Technica: The skinny on RAID - May 2000, by Matt "Panders" Anderson & Ken "Caesar" FisherĮECS Department, University of California, Berkeley: A Case for Redundant Arrays of Inexpensive Disks (RAID) - December 1987, by David A. There are many reasons for a Redundant Array of Independent Disks (RAID) system to fail (RAID controller failures, software RAID emulator errors, etc.). UNERASER provides an easy way to assemble array disks together and make damaged or deleted data accessible. You can combine together a disk that was previously used as a part of a RAID system in a temporal (virtual) disk array. With this virtual configuration, you are able to perform all drive file recovery manipulations as though it is regular drive. You can even to create a Disk Image for the whole RAID and store it to the safe location. It is important that you specify the parameters of the RAID system that you know existed before the fault so that you can virtually reassemble the same system. It is also important to list the disks in the correct order when making a virtual disk array. In most cases, the correct order is unknown. The only way to discover the correct order is to try all available combinations until you reach the one that works. If you are dealing with only two disks, it is simple.
