All, We have a pair IBM P690 machines running AIX 5.3. I was wondering if anyone is running RAC on these machines. Is it true I would need to use RAW devices because of RAC? "Normal" file systems would not work for RAC. And can the machines be geographically apart from each other (like within a mile)? Last I heard the physical distance was a problem, but things change fast around here. Thanks Tom Mercadante
