Veritas Volume Manager

The Veritas Volume Manager (VVM or VxVM) is a proprietary logical volume manager from Veritas (which was part of Symantec until January 2016). It is available for Windows, AIX, Solaris, Linux, and HP-UX. A modified version is bundled with HP-UX as its built-in volume manager. It offers volume management and Multipath I/O functionalities (when used with Veritas Dynamic Multi-Pathing feature).

A lawsuit alleging Microsoft leaked trade secrets and violated a contract over code used in Windows Vista. Microsoft once licensed a version of Veritas Volume Manager for Windows 2000, allowing operating systems to store and modify large amounts of data. Symantec acquired Veritas on July 2, 2005, and claimed Microsoft misused their intellectual property to develop functionalities in Windows Server 2003, later Windows Vista and Windows Server 2008, which competed with Veritas' Storage Foundation, according to Michael Schallop, the director of legal affairs at Symantec. A representative claims Microsoft bought all "intellectual property rights for all relevant technologies from Veritas in 2004". The lawsuit was dropped in 2008; terms were not disclosed.
