Ex5 came out and I went to a lunch and learn in Portland to check them out. There are some pretty amazing changes going on with the new architecture. I also like that they have a new SAN that is just solid state drives.
The biggest change besides the faster processors is that they have tons of RAM slots. This way you can create a lot more VMs.
At the end I asked them why they are still using Intel chips instead of their own Cell chips, and they did not want to answer the question. I should look further into this.
They use them in the PS3 game console and work amazing. What reason could they have for not using them in a server?
