'''Oracle ZFS''' is [[Oracle Corporation|Oracle]]'s proprietary implementation of the [[ZFS]] [[file system]] and [[Logical volume management|logical volume manager]] for [[Oracle Solaris]]. ZFS is a registered trademark belonging to Oracle.<ref>{{cite web | url =https://tsdrapi.uspto.gov/ts/cd/casestatus/sn85901629/content | title =Status Information for Serial Number 85901629 (ZFS) | publisher =United States Patent and Trademark Office | access-date =October 21, 2013 | archive-url =https://web.archive.org/web/20131021232022/https://tsdrapi.uspto.gov/ts/cd/casestatus/sn85901629/content | archive-date =October 21, 2013 | url-status =dead }}</ref>

==History==
{{See also|ZFS#Implementations|OpenZFS#Implementations}}

===Solaris 10===
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===
After Oracle's Solaris 11 Express release, the OS/Net consolidation (the main OS code) was made proprietary and closed-source,<ref>{{cite web
| url = http://techie-buzz.com/foss/oracle-has-killed-opensolaris.html
| title = Oracle Has Killed OpenSolaris
| publisher = Techie Buzz
| date =August 14, 2010
| access-date =July 17, 2013
| archive-url = https://web.archive.org/web/20131015165133/http://techie-buzz.com/foss/oracle-has-killed-opensolaris.html
| archive-date =October 15, 2013
| url-status = live
}}</ref> 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===
On September 2, 2017, [[Simon Phipps (programmer)|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.<ref>{{Cite web
