ZFS
open-in-new
<p>ZFS (previously Zettabyte File System) is a <a href="/facts/File_system/FdPm90uc">file system</a> with <a href="/facts/Volume_manager/ku3Ivefk">volume management</a> capabilities. It began as part of the <a href="/facts/Sun_Microsystems/VJ9EzEFd">Sun Microsystems</a> <a href="/facts/Solaris_(operating_system)/KPfT98EJ">Solaris</a> <a href="/facts/Operating_system/8XTuvMh2">operating system</a> in 2001. Large parts of Solaris, including ZFS, were published under an <a href="/facts/Open_source_license/FlFTwHmd">open source license</a> as <a href="/facts/OpenSolaris/7q5ouhPa">OpenSolaris</a> for around 5 years from 2005 before being placed under a closed source license when <a href="/facts/Oracle_Corporation/0z14FygH">Oracle Corporation</a> acquired Sun in 2009–2010. During 2005 to 2010, the open source version of ZFS was <a href="/facts/Software_port/7s6tFs8B">ported</a> to <a href="/facts/Linux/9FvCKSTq">Linux</a>, <a href="/facts/Mac_OS_X/Y93vVpTm">Mac OS X</a> (continued as <a href="/facts/MacZFS/B3BnIxHY">MacZFS</a>) and <a href="/facts/FreeBSD/RKsFTm7F">FreeBSD</a>. In 2010, the <a href="/facts/Illumos/helcbXv6">illumos</a> project <a href="/facts/Fork_(software)/D6khxhpr">forked</a> a recent version of OpenSolaris, including ZFS, to continue its development as an open source project. In 2013, <a href="/facts/OpenZFS/HcC7EaMU">OpenZFS</a> was founded to coordinate the development of open source ZFS. 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. OpenZFS is widely used in <a href="/facts/Unix-like/YAKrAxzd">Unix-like</a> systems. </p>
