Using ServeRAID Adapters to Avoid Data Loss
RAID-5 and RAID-1 technology provides the ability to continue operation
after the failure of a hard drive and the ability to rebuild the lost
data onto a replacement drive.
In conjunction with the bad sector remapping capabilities of the hard drives, RAID-5 and RAID-1 can also
help recreate data lost due to sector media corruption.
The RAID-5 logical drive must be synchronized initially to ensure that the RAID-5 parity used to reconstruct data
in the event of an unreadable sector is correct.
Perform data scrubbing weekly on the RAID-5 and RAID-1 logical drives to
minimize the risk of undetected and, therefore, uncorrected sector media
errors on the remaining drives in the array.
Defective sectors on hard drives are not uncommon. Data scrubbing helps you detect and correct these
errors before they become a problem.
If the ServeRAID Array is not properly set up and/or maintained, a significant risk of data loss grows
with the passage of time.
This manual examines how to avoid data loss wherever possible.
