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

Single port configurations
The example shows the simplest configuration of a single subnet containing just one 1GbE network
port, generally this configuration is likely to be used:
• Only if the network interface is required only for management of the appliance or
• Only if low performance and resiliency backup and restore are acceptable.
A single 10GbE port could also be configured in this way (on 4420/4430 appliances), providing
both a backup data interface and management interface. This could deliver good performance,
however, bonded ports are recommended for resiliency and maximum performance.
