Lotus Foundations Branch Office contains a Lotus Domino server that may be used like any other Lotus Domino server, but there are some Lotus Foundations Branch Office licensing differences:
- It must be used as a ″spoke″ within an existing Lotus Domino Enterprise server ″hub and spoke″ infrastructure
- It must connect into a hub that is a Lotus Domino Enterprise server or IBM Lotus Domino Messaging Server
- It can be used with up to 500 users
- The Lotus Foundations Branch Office server cannot be clustered
- It does not include bundled packages normally included in other Lotus Domino® packages, such as IBM® WebSphere® Application Server, IBM WebSphere Portal Server, IBM Tivoli® Directory Integrator or IBM DB2® Enterprise Edition packages
I can live without clustering and the Websphere/Tivoli/DB2 bundle but the gotcha is in the hub and spoke rule. A Foundations server can't be a hub so you can't create a hub and spoke topography consisting of just two Foundations servers. To be fair to IBM, they are selling this unit as a Branch Office solution so you're getting exactly what you paid for.
Where I'm unclear at the moment is how LFBO works in an organisation with (say) 900 users equally divided between three sites with the primary site as a Domino Enterprise server talking to a couple of remote LFBO servers on the spokes. It might need some technical juggling to reconcile the Foundations security model with the existing Domino Enterprise server address book, especially if you are migrating two thirds of your existing Domino ids into Foundations ids.
One things for sure... this model will take more than 30 minutes per server to set up and bed down.
