OpenSolaris, illumos distributions, OpenIndiana, FreeBSD, Mac OS X Server 10.5 (only read-only support), NetBSD, Linux via third-party kernel module ("ZFS on Linux") or ZFS- FUSE, OSv Forked from OpenSolaris August 2010 12 years ago ( 2010-08) Sun Microsystems ( acquired by Oracle Corporation in 2009) OpenZFS is widely used in Unix-like systems.
#Maczfs vs zevo code#
OpenZFS maintains and manages the core ZFS code, while organizations using ZFS maintain the specific code and validation processes required for ZFS to integrate within their systems. In 2013, OpenZFS was founded to coordinate the development of open source ZFS. In 2010, the illumos project forked a recent version of OpenSolaris, to continue its development as an open source project, including ZFS. During 2005 to 2010, the open source version of ZFS was ported to Linux, Mac OS X (continued as MacZFS) and FreeBSD.
#Maczfs vs zevo license#
Large parts of Solaris – including ZFS – were published under an open source license as OpenSolaris for around 5 years from 2005, before being placed under a closed source license when Oracle Corporation acquired Sun in 2009/2010.
It began as part of the Sun Microsystems Solaris operating system in 2001. ZFS (previously: Zettabyte file system) combines a file system with a volume manager. One of the former Apple staff members who spearheaded that effort, has reconstituted his efforts as Ten's Complement.For other uses, see ZFS (disambiguation). The summary result of all of these efforts made by Sun, Apple, and the MacZFS community is the drastic advancement of the state of the art of storage technology on Mac OS. Development has ensued in the years since. The community reacted immediately to the disorienting setback by mirroring all historical resources, by opening this project page, and by starting various personal source code forks. This was severely exacerbated by overarching legal aggression from Net App toward Sun, and hence toward Sun's customers such as Apple.įorever grateful to Sun and Apple and to all of their brilliantly visionary engineers for the generous head start, the community fearlessly resumed the project's development. After a lengthy hiatus from the public eye prior to the final release of Mac OS 10.6, the company unceremoniously withdrew their involvement from the ZFS community both internally and publicly, by suddenly deleting all traces of ZFS from Mac OS and from their web sites.Įxplanations for this action involve a failure to achieve a private licensing agreement between Apple and Sun over the ZFS source code. Apple hosted the project at the now defunct the now defunct original mailing list is now mirrored at Nabble. The company distributed ZFS as a read-only kernel extension in Mac OS 10.5 and later as a fully functional suite in the developer beta builds of Mac OS 10.6. Years ago, Apple began the visionary and ambitious undertaking of porting ZFS to Mac OS.
