I have been convincing customers.  You can, too.
1. There needs to be more than one path out of the box (high availability)
2. Each path is via a separate OSA port
3. Do not connect all OSAs to the same switch
4. Define multiple virtual routers sharing the OSA connections.
5. The primary for each OSA terminates is assigned to one of your virtual
routers.  The others are defined to be secondaries.
6. If you have more requirements for primary OSA connections, buy more OSA
ports.  Don't interfere with the other primaries.
7. Order more OSA features than you think you will need.

In short, design a virtual network with the same care you would a real
network.  The amount of redundancy is proportional to the value of the
service.

That is really the important thing, isn't it?  When the voices stop, I
mean?  (Chuckie's ghost told me to say that...Oh, great, now I'm seeing
ghosts!  Chuckie will be upset with me....)
