Subject:	Multiple Archiver Appliances on same host, different NICs

We are setting up a new host with enough resources to run 3 AA instances.

It makes sense to use more than a single NIC to handle a large network load.

The idea is to separate the AA instances and NICs, to cover different subnets with some overlap.

I'd rather not use a container like Singularity right off the bat, although that might end up beieng the best practice after all.

In the appliances.xml file I know that I set the appliance id and inet which points to

directories in Tomcat.

Can I use a FQND like, appliance01.als.lbl.gov:17665 and another

entry, appliance02.als.lbl.gov:17665 and do forth ? Where the appliance ID is also the IP address.

Of course "appliance01" would have to match the Tomcat context directory as well, where all the WAR files are deployed.

Or, do I just multihome the host and the Linux kernel handles it ? Then use different port ranges for each instance in the appliances.xml file.

Not really sure how to ask this question, thanks in advance for your patience.
