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

Scenario 1, single fabric with dual switches, recommended
Figure 40 illustrates the logical connectivity between the hosts and the VTLs and their FC ports. The
arrows illustrate accessibility, not data flow.
FC configuration
• Multiple switches within a single fabric
• All hosts can see the robots over two separate switches
• Zoning by WWPN
• Each zone to include a host and the required targets on the HP B6200 Backup System
• Equivalent ports from each node can see the same switch
B6200 VTL configuration
• Default library configuration is 50% drives presented to Port 1, 50% presented to Port 2
• Up to 120 WWNs can be presented to Port 1 and Port 2
• On B6200 failover all WWNs of failed node are automatically transferred to the corresponding
port on the other node. This is transparent to the hosts.
