Replication Licensing:
HP delivers replication by license, either as a standalone replication solution, or as part of the HP
StoreOnce Catalyst licensing (see the following section below). With HP StoreOnce Backup,
replication is licensed by VTL/NAS target, this means that with one replication license:
1 source appliance can replicate to a single HP StoreOnce VSA*
8 source appliances can replicate to a single HP StoreOnce 2620
24 source appliances can replicate to a single HP StoreOnce 4210 or 4220
50 source appliances can replicate to a single HP StoreOnce 4420 or 4430
96 source appliances can replicate to a single HP StoreOnce B6200 48 TB target
