ell PowerEdge servers can have a wide variety of RAID configurations, but most PowerEdge
Servers are setup as a stripe set with parity ( RAID 5). The default for the RAID stripe is 64k (128 sectors). The data is striped across all the disks, and a parity block rotates between drives. This way if one disk fails, the RAID card can default to degraded mode and run without interruption. A problem arises when there is corruption within some essential parity blocks, or simply more than one drive fails at about the same time, not giving the IT professional enough time to replace the first failed drive. This results in a failed RAID volume.
Our certified Engineers are familiar with the entire PERC Controller family and have a decade of experience behind them. There are few situations that are not recoverable. The only exception is when the drives have been rebuilt in the wrong configuration. In this case, it is possible to overwrite the data, making data recovery impossible.
The RAID Engineers at acedatalab.com have the expertise to recover data at both a hardware and software level, sometimes writing custom software on the fly to fit your recovery situation. In many cases we will remove the platters from a failed drive, create a clone of this drive using custom equipment, and then recreate your original volume from this clone and the good drives.
If your RAID has crashed and you are not sure what the next step is consult with a data recovery engineer. Call us now at 305-2286163 for a free consultation.
