Hi Billy!

    Thank for valuable information. We also like more AMD, than anything else : ))). What boxses do you use (v20z/v40z)? What disk array is used as a shared storage? We are going to try StorEdge3510FC, cause we use them now, but not sure that these arrarys are 100% compatible with Linux (i mean host bus adapters - we haven't found any appropriate yet). It might be 3511FC.

What Linux do you use? How many nodes has your RAC?

Sorry for so many questions - the case is quite important for us, and we don't have too much time to make a decision - deadline in three weeks...
