I am no storage expert but I would like to throw in a couple of points
Quote "For all 11g ASM/DB users, it best to create a disk group using 4 MB ASM AU size. Metalink Note 810484.1 covers this" - slide 15
If that is the case then why did Oracle provide a range of AU_SIZE in 11G ( 1M, 2M, 4M, 8M, 16M, 32M, 64M)? I do not believe one size fits all as far as au_size is concerned.
Secondly when I raised this with Oracle when we were building a new DW I ended up in a conference call with Bill Bridge the designer of ASM who recommended us to use 8M AU_SIZE.
