I recently got a freenas system up and running. I've been reading a lot into how ZFS works with RAM and caching and haven't found a definitive answer. Can you have too much RAM on a ZFS system? I know the recommendation is 8GB minimum with 1GB per 1TB but are there any adverse effects of having more?
Specs are:
2x Intel Xeon L5520
96GB Ram
20TB in RaidZ2 (12 TB usable)
6TB in mirrors (3tb usable)
Also, should I run autotune or is autotune only for systems with lower RAM than recommended?
