RAID 50 storage arrays combine the redundancy, speed and efficient use of storage in RAID 5 arrays, with the speed of striping from RAID 0. At least 6 disks are required to set-up a RAID 50 array.
RAID 50 disk configuration is a set-up where the data is striped at a block level across two or more RAID 5 arrays; where the data has distributed parity information across a minimum of three hard disks. The RAID 0 striping gives you extra speed, while the distributed parity provides fault tolerance, whereby one disk in each RAID 5 can fail without causing the array to fail. The data on a failed disk can be rebuilt from the parity information stored on the remaining working disks within the individual RAID 5 configuration.
When a RAID 50 array fails, RAID 50 recovery is still possible because of the redundancy built into each RAID 5 array. However if more than one disk in any individual RAID 5 array fail at the same time, then the missing data from the failed disks may not be rebuilt without expertise and RAID 5 data recovery experience.
RAID 50 data recovery requires a thorough understanding of the disk sequencing, RAID stripe lengths and XOR parity information along with experience in file systems and data structures. The combination of RAID 0 striping across RAID 5 arrays, adds an additional complexity to the understanding of the how the arrays are configured.
DiskEng RAID 50 data recovery specialists can recover your data from RAID 50 storage arrays. For many years now our RAID 50 recovery specialists have been recovering data from a wide range of complex RAID arrays.
Some popular RAID array systems that we have recovered data from:
- NetWare RAID arrays
- NTFS RAID arrays
- MAC RAID arrays
- UNIX RAID arrays
- XFS RAID arrays
- And others.
If your RAID 50 volume is inaccessible, there is no need to panic, as our RAID 50 recovery experts have recovered data from hundreds of RAID servers over the years. For expert advice and successful recovery speak to our data recovery specialists today.
