Oracle and SUN When it comes to dealing with storage, Solaris 10 provides admins with more choices than any other operating system. Right out of the box, it offers two filesystems, two volume managers, an iscsi target and initiator, and, naturally, an NFS server. Add a couple of Sun packages and you have volume replication, a cluster filesystem, and a hierarchical storage manager. Trust your data to the still-in-development features found in OpenSolaris, and you can have a fibre channel target and an in-kernel CIFS server, among other things. True, some of these features can be found in any enterprise-ready UNIX OS. But Solaris 10 integrates all of them into one well-tested package.

RE[2]: ZFS is a dead end.

Can't say I disagree. The layering violations are more important than some people realise, and what's worse is that Sun didn't need to do it that way. They could have created a base filesystem and abstracted out the RAID, volume management and other features while creating consistent looking userspace tools.

Please stop parroting one Linux developer's view. Go look at the ZFS docs. ZFS is layered. Linux developers talk crap about every thing that is not linux. Classic NIH syndrome.

ZFS was designed to make volume management and filesystems easy to use and bulletproof. What you and linux guys want defeats that purpose and the current technologies in linux land illustrate that fact to no end.

The all-in-one philosophy makes it that much more difficult to create other implementations of ZFS, and BSD and Apple will find it that much more difficult to do - if at all really. It makes coexistence with other filesystems that much more difficult as well, with more duplication of similar functionality. Despite the hype surrounding ZFS by Sun at the time of Solaris 10, ZFS still isn't Solaris' main filesystem by default. That tells you a lot.

That's just plain wrong. ZFS is working fine on BSD and OS X. ZFS doesn't make coexistence with other filesystems difficult. On my Solaris box I have UFS and ZFS filesytems with zero problems. In fact I can create a zvol from my pool and format it with UFS.
