Oracle Rac and IBM P-series machines

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
