Recommended cache ratio

Are there guidelines (published or otherwise) on what to set the read/write ratios for based on server OS and its role (file server, mail server, database server, etc)?
thanks!

Re: Recommended cache ratio

The only guidance I've ever seen was a recommendation of 60% read and 40% write for a typical file server. Unfortunately you can only change the default ratio in 25% increments within the Array Configuration Utility, so your only options are really 25/75, 50/50 or 75/25. I don't think you'd ever want to run it down to 0 on either value. Good luck.
