So, Barcelona based Opterons are finally out, does anyone have hands-on experience of their performance in ESX 3.5 compared to their Xeon siblings?
I am particularly interested in these new Opterons because of their nested page table support, or rapid virtualization indexing, what it is called now. As I understand NPT/RVI is supported in ESX 3.5?
It's pretty good! Check out Dell's recent submissions for VMmark scores. At 2.5GHz the new Opterons are very close to 2.93 Xeons. I personally have been involved with those parts with RVI enabled on virtualized Exchange mailboxes. The numbers are very encouraging given how long we've waited for those parts. The numbers will be published by one of our partners in coming weeks.
