Oracle ZFS is Oracle's proprietary implementation of the ZFS file system and logical volume manager for Oracle Solaris. ZFS is a registered trademark belonging to Oracle.[2]
History
[edit]Solaris 10
[edit]In update 2 and later, ZFS is part of Sun's own Solaris 10 operating system and is thus available on both SPARC and x86-based systems.
Solaris 11
[edit]After Oracle's Solaris 11 Express release, the OS/Net consolidation (the main OS code) was made proprietary and closed-source,[3] and further ZFS upgrades and implementations inside Solaris (such as encryption) are not compatible with other non-proprietary implementations which use previous versions of ZFS.
When creating a new ZFS pool, to retain the ability to use access the pool from other non-proprietary Solaris-based distributions, it is recommended to upgrade to Solaris 11 Express from OpenSolaris (snv_134b), and thereby stay at ZFS version 28.
Future development
[edit]On September 2, 2017, Simon Phipps reported that Oracle had laid off virtually all of its Solaris core development staff, interpreting it as a sign that Oracle no longer intends to support future development of the platform.[4]
