The SAFE50 storage policy creates two virtual volumes; one SAFE volume and

one BIG volume, and should be used when you need the high reliability for some

of your data (with the added overhead of mirroring) but you don’t need high reli-

ability for the remainder of your data.

SAFE50 reduces the cost of additional hard drives in operations where non-critical

data could be lost without severe consequences.

SAFE50 uses a SAFE volume that is mirrored across two hard drives to protect

your critical data in the event a hard drive failure. If one drive fails the SAFE

volume is retrievable although the BIG volume is not. When you replace the failed

drive, the SAFE volume is automatically rebuilt on to the replacement drive.

For example, if you are using a video editing application that stores the primary

source data and also uses some temporary storage for editing, you need protect-

ed storage that is covered by SAFE for the primary source data, but you do not

need protected storage for the temporary data.

Therefore, the combination of SAFE and BIG would be the most efcient utilization

of your available storage capacity. If either hard drive fails the primary data stored

on the SAFE volume would still be available whereas the temporary data stored

on the BIG volume would be lost.
