Oracle and SUN Today Oracle released its latest version of Solaris technology, the Oracle Solaris 11 Express 2010.11 release. It includes a large number of new features not found in either Oracle Solaris 10 or previous OpenSolaris releases including ZFS encryption and deduplication, network-based packaging and provisioning systems, network virtualization, optimized I/O for NUMA platforms and optimized platform support including support for Intel's latest Nehalem and SPARC T3. In addition, Oracle Solaris 10 support is available from within a container/zone so migration of existing systems is greatly simplified. The release is available under a variety of licenses including a supported commercial license on a wide variety of x86 and SPARC platforms.

ZFS was originaly touted on Apple website for one of previous releases of OSX (10.5 or 10.6 can't remember) Of course it didn't help that Jonathan Schwartz had to open his big mouth and announce that it was gonna be default filesystem in OSX. Jobs just doesn't like other people pre-announcing stuff. Given the rapprochement between Oracle/Apple over Java we might be lucky and see ZFS as part of 10.7 (lion).

That's more of a pipedream on my part but you never know. The recent "back to Mac" event said very little about Lion other then about some of the GUI stuff and the release name. Given that OSX currently uses DTrace and Solaris NFSv4 stack (client/server) I wouldn't be surprised if ZFS snuck back in. Helps that the NetApp case has ended. Plus ZFS is even better now then it was two years ago with stuff like DeDup and Crypto now included.


From what I understood it all came down to patents and licensing plus other stuff - stuff that could have over come if Sun (and subsequently Oracle) had the will power to do so. Even if they did get ZFS working with Mac OS X the problem I found when using it with OpenSolaris was that the performance was terrible on anything less than 2GB of RAM using a 32bit kernel on a low powered machine - which would have pretty much killed off using it on the MacBook Air. What Apple needs isn't something revolutionary but rather something that is evolutionary and does what is required without too much fanfare.

One possible replacement for HFS+ that comes to mind could be HAMMERFS from DragonflyBSD:

It includes many cool features and is licensed under a liberal license which will allow Apple to bring it over to XNU and make the necessary enhancements for Finder integration. Sure, it isn't a massive leap in the case of ZFS but the file system sticks to the tried and true way of doing things - I'd sooner have that than risk a jump into the unknown for the sake of having something on the bleeding edge.
