Migration for Capacity
The ARX can keep all filers at or above the same minimum free space, so that
overburdened filers can offload their files to other filers. This is called auto-migration
off of the filer that is low on free space. You configure this by declaring a share farm
and establishing the auto migration rule in the share farm. The internal policy engine
balances capacity by migrating popular files from an over-filled share to the shares
with more free space. For example, consider a scenario where several larger filers are
under-utilized and two DAS-enhanced file servers are nearly filled to capacity:
NAS NAS NAS
file servers (DAS
