I'm venturing into the land of Oracle RAC for the first time and will be installing an 11.2.0.3 2-Node cluster from scratch. The storage will be allocated from a Dell Compellent (not sure if that's relevant to my question or not). The official documentation recommends the use of ASMLib but I seem to remember a lot of folks on here thinking that was a bad idea or at least not a no brainer.
What's the current recommendation / bestest idea on ASMLib use?
Also, any recommendation on the number of LUN's to start off with for each disk group? (+data, +fra) Oracle recommends a minimum of 4 but I'm not sure how they arrived at that number or whether more would be advantageous. That's probably an "it depends" question so what info do I need to make that determination?
Thanks,
Chris
