Q:
Combination of physical and virtualized blades
For a midsize company, what situation do you think justifies a combination of physical blades and virtualized blades? Why not just go virtual altogether?

I have run into several cases where virtualization was not an option. Some software will run terribly slow on a virtual server....Lotus Domino is such a known piece of software. It works but the drop in performance is big with older versions.
Then there is the thing with licenses. Oracle databases are generally not a good thing to run virtualized. Usually not for performance reasons but from a licensing perspective. Oracle still doesn't recognize X86 virtualization as hard partitioning. They will force you to buy licenses for all of the CPU's of the physical box.
We can specualte about Oracle's reasons. One of them could be that they are turning into a datacenter player with the acquisition of Sun...... who knows.
For larger virtual servers it also remains to be seen if the virtual sever is actually cheaper. The new Intel Nehalem blades are quite cheap and low power. You would have to get more features of the virtual platform into the busines case to make it work.
Sure, blades and virtual systems will coexist for some time.
