filesystemio_options parameter when working with SAN

doctordbaJan 14 2014 — edited Jan 14 2014

Hi,

I'm running Oracle DB 11.2.0.3 on RHEL 5.7, all DB files located on SAN Storage (EMC vnx-5300).

I was wondering if changing filesystemio_options from 'none' to set all would make any difference because as far as i understand it

This storage signal the OS when the request is written to his cache it does not really wait to write the request to the disk (so basically it async IO anyway? even if the os\oracle thinks it's sync IO).

What do you think?

Ron
