Nice!

I would add the following points in regards to High Availability:

- REQUIREMENTS (in Upper Case) document that specifies exactly what do the want

- Recovery Model

- DRP

- Virtual Server (as in Virtual Server software, not a cluster) can be deployed in 10 min from an image with all SW installed, just restore a last backup of the database.

- A DRP machine with OS and Database server may even stay shut down waiting for any database or app to be copied /restored. Financial benefits that you may have with DRP machine is that it is only one server standing by for many production servers.
