* Federated deduplication is an HP term referring to the ability to distribute the deduplication load
across Media servers. This feature is sometimes known as source-based deduplication or low
bandwidth backup.
Networking and Fibre Channel considerations
NOTE: See Networking considerations and Fibre Channel considerations for more information
about Ethernet and FC configurations and best practices.
The following table shows which network and fibre channel ports are present on each model of
StoreOnce appliance. Correct configuration of these interfaces is important for optimal data transfer.
A mixture of iSCSI and FC port virtual libraries and NAS shares can be configured on the same
StoreOnce appliance to balance performance needs if required.
• The HP StoreOnce B6200 Backup system does not support iSCSI virtual libraries.
• The HP StoreOnce 2700, 2620 and 4210 iSCSI Backup systems do not support FC virtual
libraries.
