    1. FreeBSD 각 버전별 ZFS

    7.0+ : original ZFS import, ZFS v6; requires significant tuning for stable operation (no longer supported)
    7.2 : still ZFS v6, improved memory handling, amd64 may need no memory tuning (no longer supported)
    7.3+ : backport of new ZFS v13 code, similar to the 8.0 code
    8.0 : new ZFS v13 code, lots of bug fixes - recommended over all past versions. (no longer supported)
    8.1+ : ZFS v14
    8.2+ : ZFS v15
    9.0+ : ZFS v28


    2. ZFS버전별 OS

    10 - Supported by Solaris 10 U7
    14 - Supported by OpenSolaris 2009.06, FreeBSD 8.1
    15 - Supported by Solaris 10 10/09 (U8), FreeBSD 8.2
    17 - Triple Parity RAID-Z
    19 - Supported by Solaris 10 09/10
    21 - Deduplication
    22 - Solaris 10 9/10 (U9)
    28 - FreeBSD 9.0, OpenIndiana/Illumos, ZFSOnLinux, ZFS-FUSE
    30 - Encryption support, - not compatible with open implementations, only in closed source for-license Solaris 11 Express release.


    3. ZFS버전별 특징

    ZFS pool의 버전별 간단한 특징을 확인하려면 zpool upgrdade -v 명령으로 볼 수 있다. 기본적인 특징을 command로 쉽게 볼 수 있도록 했다니, ZFS의 마인드가 맘에 든다.

    다음은 FreeBSD 9.0 beta(v28까지 지원)에서 확인한 결과이다.

    * FreeBSD 7.x에서 ZFS 사용 & 성능(2009, 글 좋은진호)
      7.x에서 테스트한 오래전의 글이라서 성능보다는 ZFS사용에 중점을 두고 있으세요.
