https://community.hpe.com/t5/disk-enclosures/recommended-cache-ratio/m-p/2577273#M2684 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.
