I just ran into a thread on VMTN that is exactly what we are hosting a chat on later today. The VMTN thread is titled Physical Hardware Recommendation, but I am calling the same topic Selecting a Virtualization Server. Very coincidental that this thread was started today and it even specifically asks about 2950s and R900s. So for the record - this VMTN thread was not a planted thread by me or some secret Dell conspiracy. I do have to confess that it was Scott that spotted this thread first and he deserves the credit (Again!).
