Yes.

Well.. I would fricken well hope so as we're busy buying another half dozen AMD64 based blades after purchasing 30+ already. ;-)

No major issues at all. Uptime is excellent. Had a few minor h/w issues Sun had to resolve (faulty h/w). Performance is also excellent. I used a V440 Sun/Solaris box to prototype the system on before it was production deployed on the AMD64 Linux RAC - a single AMD64 node running a serialised process seems a lot more "snappier" in response than the V440 was running the same process.

OCFS for the cluster registry and voting files. Raw devices managed by ASM for the database.

I would not use OCFS for the database. Raw devices and ASM are easier to configure and use.. and likely performs a tad faster too.

Well, I'm the wrong person to ask. I'm biased. Using AMD only for all my PC systems since the P2 was released in the 90's. Currently have two AMD64 systems at home (running btw the exact same Linux version as the AMD64 10G RAC). Intel inside? Stuff that!! AMD instead! :-)
