Improved DAOS encryption security
DAOS object encryption now offers more secure encryption algorithms and the ability for Domino cluster mates to share encryption keys so that encrypted DAOS objects can be shared across servers.
Sharing DAOS tier 2 objects across servers
Beginning with HCL Domino 12, you can conserve storage space by sharing DAOS tier 2 objects across servers.
Improved DAOS container management
In HCL Domino 12 DAOS has changed the way that it fills subdirectories. It now backfills existing sub-directories (e.g. 0001, 0002) continuously. This change eliminates the partially filled or empty subdirectories that could occur in previous versions of Domino.
