ZFS Rules

Best of open source in storage: "Our first storage Bossie goes to ZFS, or Zettabyte File System , introduced with Solaris 10 and made available to the open source community in OpenSolaris. NFS is not quite dead or obsolete yet (in fact it’s still improving with Version 4 in the make), but eventually NFS has to give way to ZFS. ZFS has so many innovative features that it may take some time before storage admins can wrap their arms around it. Imagine never having to check your systems for data integrity because it’s guaranteed by the file system. Add built-in logical volume management and RAID management, then stretch capacity to a galactic dimension, a one followed by 21 zeroes. In short, ZFS hides many dirty details of storage administration, and it can scale as far as it is physically possible to go. As we noted in our review, ZFS is the best file system we've ever seen, and it belongs to the open source community. Just don’t expect to find it in your favorite Linux distro quite yet." -- InfoWorld

It would be nicer if they knew NFS and ZFS were two very different beasts.

Jim,

I'm not quite sure I understand your direction here. ZFS and NFS fill two different positions in the file system ecosystem. NFS is a cross platform NETWORK FS. ZFS is only available to the local system and does not support sharing either via SAN or network.

NFS is an industry standard supported by a wide variety of vendors in OS and NAS products.

Please elaborate.

Hi ... I'm just quoting InfoWorld on their award for ZFS. If they are totally wrong re NFS, I'll put a note in the blog pointing to these comments.

Actually ZFS includes iSCSI support, though it is not a network FS itself.

Patrick, ZFS does NOT include iSCSI support anymore than ZFS includes NFS support. For both NFS and iSCSI the "share" information is stored as a property of a ZFS dataset and ZFS calls the NFS and iSCSI sharing code as a consumer. The same will be true of other network filesystems soon.

Seem to be comparing apples and oranges here. Perhaps ZFS will replace UFS (and even VxFS if VERITAS don't keep up), but how it'll replace NFS I just can't see.
