We are looking for a method to encrypt the FC-IP tunnels between our B20 Peer to Peer tape libraries which are located about 1000kms apart. At present we use Brocade Edge 3000s - the plan was to swap these for Brocade 7500's as they offer IPsec - we already have done this on the disk replication side as True Copy is simple Fibre Channel. We now think there may be a conflict between IPsec on the FC-IP tunnel and Tape Acceleration - unconfirmed in writing but I have seen/heard some evidence to support that the features are mutually exclusive.
We also see potential problems with link outages - the Edge 3000s handle swapping from the primary to alternate IP paths transparently - with the 7500 devices, we are told that the CHPID will go offline and require intervention to re-establish - there are also potential problems with VTC recovery in this scenario. Any other Peer to Peer users care to share their working configs???
