History

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, [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

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]
