Proprietary file system and logical volume manager by Oracle
This article is about the proprietary filesystem. For its open-source alternative, see
OpenZFS .
Oracle ZFS isOracle 's proprietary implementation of theZFS file system andlogical volume manager forOracle Solaris . ZFS is a registered trademark belonging to Oracle.[ 2]
In update 2 and later, ZFS is part of Sun's own Solaris 10 operating system and is thus available on bothSPARC andx86 -based systems.
After Oracle's Solaris 11 Express release, the OS/Net consolidation (the main OS code) was made proprietary and closed-source,[ 3]
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.
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]
