  DELL  Power Edge  RAID Recovery.

We successfully recover Dell Power Edge RAID Servers. Dell PowerEdge RAID servers are configured using PERC in association with Powervault DAS.   The models we are familiar with are  MD1000, MD3000,  AX4/5, and use SATA, and SAS hard drive storage interfaces. Occasionally our technical team are faced with SCSI legacy systems.

Dell Power Edge Data Recovery Typical Fault Conditions.

Dell PERC controllers are renowned for quickly taking “failed drives” offline.  Just a blip  involving  S.M.A.R.T. error will result in a drive being removed from the array.  These circumstances occur at the same time on matched drives and result in a  degraded System that may not be able to auto rebuild.  Whilst troublesome for the organisation the system is invariably recoverable  The drives that have dropped out of the array  are usually readable using Datlabs  specialist hardware and applications.

Datlabs RAID team will image all hard drive’s / volumes in the the array and verify their accuracy. This preserves the original array and its stored data . Our engineers will then determine the  health and precise order and configuration of  the volumes within the array and in this process remedy any faults affecting the failed hard drives.,   The array can then be rebuilt and its data transferred to return media or the clone array prepared for replacement.

If you are in need of  a Professional RAID Data Recovery Service.

If you’re looking for professional data recovery from a failed Dell RAID  then Datlabs have the experience and facilities to rebuild and retrieve your data.

DELL Poweredge RAID Failure.

Datlabs RAID Rapid Response Team are available 24 x 7  and have unparalleled experience in DELL PowerEdge RAID configured Servers with success rates second to non.

Our team have recovered:

  • Failure of one or more hard drives
  • Server hardware failure
  • Faulty PERC controllers
  • Incorrectly Rebuilt Arrays
  • Systems Reconfigured in error.

fault tolerance is  different for differing configs.

  • RAID 0 configs are not tolerant drive failure. If any physical drive in the array fails, all RAID 0 logical drives in the same array also fail.
  • RAID 1 and RAID 10 configurations tolerate multiple drive failures if no failed drives are mirrored to one another.
  • RAID 5 configurations tolerate one drive failure.
  • RAID 50 configurations tolerate one failed drive in each parity group.
  • RAID 6 configurations tolerate two failed drives at a given time.
  • RAID 60 configurations tolerate two failed drives in each parity group.
  • RAID 1 (ADM) and RAID 10 (ADM) configurations.

Before replacing drives ensure that the array has a current valid backup.

Confirm that the replacement drive is of the same type as the degraded drive (either SAS or SATA and either hard drive or solid state drive) also that the replacement drive has a capacity equal to or larger than the capacity of the smallest drive in the array. The controller will immediately fails if a drive is introduced that has insufficient capacity.

Systems with External Data Storage.

Ensure that the server is the first unit to be powered down and the last unit to be powered up.

Replacing RAID Hard Disk Drives.

Drives are replaced when they have failed or when the  system needs a capacity upgrade.

In fault-tolerant configuration, hot-plug hard drives can be replaced when server is ON, but in case of a Non-hot-plug hard drive, it should be replaced when server is OFF.

Fault Tolerance.

If fault tolerance is compromised, the controller cannot reconstruct the data, and the data is likely to be lost permanently.

Time Required For A Rebuild.

The time required for a rebuild depends on several factors:

  • The priority that the rebuild is given over normal I/O operations
  • The amount of I/O activity during the rebuild operation.
  • The average bandwidth capability (MBps) of the drives.
  • The availability of drive cache.
  • The brand, model, and age of the drives.
  • The amount of unused capacity on the drives.
  • For RAID 5 and RAID 6, the number of drives in the array.
  • The stripe size of the logical volume.
  • Firmware versions of the Smart Array Controller and Hard Disk Drive.

A System could be unprotected against hard disk drive failure for an extended period during rebuild and upgrade. When possible, perform rebuild during periods of low system utilization.
