IMPORTANT: If replication needs to take place through a firewall, the network administrator will need to open (TCP) ports 9387 (Command protocol) and 9388 (Data protocol) to allow the replication traffic to pass to and from the HP StoreOnce Backup systems. Bandwidth Limiting tab This tab allows users with an Admin login to apply a general bandwidth setting and to configure bandwidth limiting windows. Bandwidth limiting can be used to avoid saturating the WAN with low bandwidth replication, thus freeing up bandwidth for other processes and applications that you may have running. A minimum of 2Mbps per concurrent job is recommended. At least 512kbps per concurrent job is required for reliable operation. These limits apply to all outbound replication jobs from this local appliance. 1. Display the Bandwidth Limiting tab. 2. Check the General Limiting Enabled box. You can now work out the recommended general bandwidth limit, which is a simple calculation of: (Max WAN Speed) x (Max Desired WAN Usage%). 102 Replication functions
