Solaris Volume Manager (SVM; formerly known as Online: DiskSuite, and later Solstice DiskSuite) is a software package for creating, modifying and controlling
RAID

-0 (concatenation and stripe) volumes, RAID-1 (mirror) volumes, RAID 0+1 volumes, RAID 1+0 volumes, RAID-5 volumes, and soft partitions.
Version 1.0 of Online: DiskSuite was released as an add-on product for
SunOS
SunOS is a Unix-branded operating system developed by Sun Microsystems for their workstation and server computer systems from 1982 until the mid-1990s. The ''SunOS'' name is usually only used to refer to versions 1.0 to 4.1.4, which were based ...
in late 1991;
the product has undergone significant enhancements over the years. SVM has been included as a standard part of
Solaris since Solaris 8 was released in February 2000.
SVM is similar in functionality to later software
volume managers such as
FreeBSD Vinum volume manager, allowing ''metadevices'' (virtual disks) to be concatenated, striped or mirrored together from physical ones. It also supports soft partitioning, dynamic
hot spares, and growing metadevices. The mirrors support dirty region logging (DRL, called resync regions in DiskSuite) and logging support for RAID-5.
The
ZFS file system, added in the
Solaris 10 6/06 release, has its own integrated volume management capabilities, but SVM continues to be included with Solaris for use with other file systems.
