Solaris Volume Manager
From Wikipedia, the free encyclopedia
Solaris Volume Manager (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 in September 1991; the product has undergone significant enhancements over the years. SVM has been included as a standard part of the Solaris Operating System since the Solaris 8 release in February 2000.
SVM is similar in functionality to other software volume managers such as FreeBSD vinum, allowing metadevices or virtual disks to be concatenated, striped or mirrored together from physical ones. It also supports soft partitioning, dynamic hotsparing, and growing metadevices. The mirrors support dirty region logging (DRL, called resync regions in DiskSuite) and logging support for RAID-5.
Sun's new file system ZFS also includes volume management capabilities, but SVM will continue to be included with Solaris for use with other file systems.
