vCenter single point of failure for View?

Hi, we are implementing a small View 5.1 deployment of about 200 virtual desktops. I have a design using 2 connection servers and 2 security servers with a load balancer to guard against a single point of failure.

I plan on using a SQL cluster for the back end DBs but I'm still stuck with how to protect the vCenter/Composer. I only have a single 3 node cluster to work with so I can't use multiple vCenter/Composer servers.

How do you manage this in your environments?

Thanks
