Do you need all those protocols for WAN networking, or are you planning to use 
it for HPC? If you're going HPC, you don't need managed anything. The vendors 
deceived us the same way when we asked them in 2000-2001. Don't trust the 
vendors, do your own research. Always put specs side by side and compare.
