Supported Direct-IO configuration
Configuration rules:
One LSU can only be used by one NetBackup domain.
One or more than one LSU can be created from the same SpanFS storage domain that is also known as a view box.
One view box is a single, independent deduplication pool (deduplication domain).
NetBackup LSU and NetBackup disk pool are 1:1 mapping.
One or more than one LSU may be created from the same view box.
Some typical configurations:
Two NetBackup domains use two LSUs created from the same view box of a SpanFS cluster. This can achieve data deduplication for backups from two different NetBackup domains.
One NetBackup domain uses more than one LSU created from the same view box of a SpanFS cluster.
One NetBackup domain uses more than one LSU created from more than one view box's of different SpanFS clusters.
