As far as RAM usage, ZFS is relatively RAM intense. I would budget about 1GB ram per 1TB of storage, 1GB per 50GB of L2ARC (if using L2ARC), and 5GB per 1TB of storage if you are using deduplication (dedupe is probably not needed except in specific workloads). For fileservers you definitely WANT ECC ram, but its not strictly required.
