High-end HP Proliant, Integrity, 9000, and Alpha servers can have a wide variety of RAID configurations, but most Proliant 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 RAID data recovery Engineers are familiar with the entire family of HP Servers, including Proliant, Integrity, Non-stop, HP9000, and even Alpha servers (yes, when we hear Alpha, we think of DEC). Our Engineers have a century
of combined experience behind them. There are few situations in which hard disk data recovery is not possible. The only exception is when the drives have been rebuilt in
the wrong configuration. In this case, overwriting may have occurred making
data recovery impossible.
The RAID Engineers at ESS Data Recovery 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, our data recovery specialists 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 clones and the
good drives.
If your Hewlett Packard Server has crashed and you are not sure what the next step is
consult with a data recovery engineer. Call us now at 1.800.237.4200 for
