HP StoreOnce Backup System Concepts and Configuration Guidelines (BB877-90913, November 2013)

10GbE Ethernet ports on StoreOnce Backup systems
10GbE Ethernet is provided as a viable alternative to the Fibre Channel interface for providing
maximum iSCSI VTL performance and also comparable NAS performance. 10GbE ports also
provide good performance when using StoreOnce Catalyst low and high bandwidth backup as
well as Catalyst copy or VTL/NAS replication between appliances. When using 10GbE Ethernet
it is common to configure a “Network SAN”, which is a dedicated network for backup that is
separate to the normal business data network; only backup data is transmitted over this network.

As well as CIFS and NFS shares the devices configured could equally be Catalyst stores.
When a separate network SAN is used, configuration of CIFS backup shares with Active Directory
authentication requires careful consideration, see the next section for more information.
Network configuration for CIFS AD
When using CIFS shares for backup on a StoreOnce device in a Microsoft Active Directory
environment the appliance CIFS server may be made a member of the AD Domain so that Active
Directory users can be authenticated against CIFS shares on the StoreOnce Backup system.
However, in order to make this possible the AD Domain controller must be accessible from the
StoreOnce device. Broadly there are two possible configurations which allow both:
• Access to the Active Directory server for AD authentication and
• Separation of Corporate LAN and Network SAN traffic
