As a bare minimum, the total system memory should be at least one gigabyte. The amount of recommended <acronym>RAM</acronym> depends upon the size of the pool and which <acronym>ZFS</acronym> features are used. A general rule of thumb is 1 GB of RAM for every 1 TB of storage. If the deduplication feature is used, a general rule of thumb is 5 GB of RAM per TB of storage to be deduplicated. While some users successfully use <acronym>ZFS</acronym> with less <acronym>RAM</acronym>, systems under heavy load may panic due to memory exhaustion. Further tuning may be required for systems with less than the recommended RAM requirements.
最低需求,总系统内存应至少有 1 GB,建议的 <acronym>RAM</acronym> 量需视存储池的大小以及使用的 <acronym>ZFS</acronym> 功能而定。一般的经验法则是每 1 TB 的储存空间需要 1 GB 的 RAM,若有开启去重复的功能,一般的经验法则是每 1 TB 的要做去重复的储存空间需要 5 GB 的 RAM。虽然有部份使用者成功使用较少的 <acronym>RAM</acronym> 来运作 <acronym>ZFS</acronym>,但系统在负载较重时有可能会因为记忆用耗而导致当机,对于要使用低于建议 RAM 需求量来运作的系统可能会需要更进一步的调校。
