RAID Information > RAID
0+1
RAID Level 0+1 (0+1) requires a minimum of 4 drives
to implement. A RAID 0+1 is a striped array
with segments consisting of RAID 0+1 arrays
and having the same fault tolerance as RAID
level 0+1 plus the overhead
fault-tolerance of mirroring. In certain
instances a RAID 0+1 array can recover
from multiple and simultaneous hard drive
failure, however, a single drive failure
will cause it to run as RAID 0. Because of limited scalability and
high inherent costs, RAID 0+1 is typically
used in imaging applications general file
servers. It tends to be a high performance
solution with reduced emphasis on
reliability.
Recovering data from RAID 0+1
Hard Drive
Arrays
Because data on
a RAID array or volume is typically critical
to business continuity, when it becomes
inaccessible due to one or more hard drives
failing, a bad RAID controller, failed
upgrade or damaged striping, it is
imperative that you shut the server down and
get expert help!
Permanent loss of data
often occurs when hard drives are swapped,
moved from one position to another or placed
in other machines in an attempt to rebuild
or repair the array. Formatting a boot drive
or partition can also damage or remove
striping reducing recoverability of data and
causing permanent loss.
The RAID 0+1 data
recovery technicians at American Data
Recovery, Inc. can rebuild failed hard
drives, repair damaged RAID volumes and
recover data your company needs if you call
before the damage is too severe. Once
platters are damaged, striping overwritten
or changed completely, the chances of
getting your data back are slim.
