addressing that.

The DP+DC isn't available yet, from Sun. Only QP+DC is, for which the
bid opens at 38k, that is a bit pricey -:)

I haven't seen any benchmarks for a 50% performance difference. Neither
have I seen any benchmarks of pure disk IO performance of specific

Thanks to everyone for their pointers to suppliers of Opteron systems.
The system I'm pricing is under a tighter budget than a production machine,
because it will be for perftests. Our customers tend to run on Dells but
occasionally run on (Sun) Opterons.

Please wait a week before buying Sun v20z's or v40z's from off of Ebay

hear the v20z/v40z's are a great way to go and I'll know more in 15 days

I certainly understand your concern, but the price and support

Mischa,
What kind of budget are you on? penguincomputing.com deals with
Opteron servers. I looked at a couple of their servers before deciding
on a HP DL145.
