good to hear, I tried to online configure a quad xeon here at dell germany, but the 6550 is not available for online configuration. at dell usa it works. I will give them a call tomorrow.

There are many asynchronous, trigger based solutions out there (eRserver etc..), but what we need is basically a master <-> master setup, which seems not to be available soon for postgresql.
Our current dual Xeon runs at 60-70% average cpu load, which is really much. I cannot afford any trigger overhead here. This machine is responsible for over 30M page impressions per month, 50 page impressums per second at peak times. The autovacuum daemon is a god sent gift :)
I'm curious how the recently announced mysql cluster will perform, although it is not an option for us. postgresql has far superior functionality.
They have 5 internal drives (4 in RAID 10, 1 spare) on U320,

Could you tell me what you paid approximately for this setup?
How does it perform? It certainly won't be twice as fast a as dual xeon, but I remember benchmarking a quad P3 xeon some time ago, and it was disappointingly slow...
