Logical Domains (LDoms or LDOM) is the server virtualization and partitioning technology from Sun Microsystems released in April 2007 for a range of UNIX server computers based on SPARC V9 architecture. Since Oracle Corporation completed the acquisition of Sun in January 2010, the product has been re-branded as Oracle VM Server for SPARC from version 2.0 onwards.
Each domain is a full virtual machine with a reconfigurable subset of hardware resources. Domains can be securely live migrated between servers while running. Operating systems running inside Logical Domains can be started, stopped, and rebooted independently. A running domain can be dynamically reconfigured to add or remove CPUs, RAM, or I/O devices without requiring a reboot.
Famous quotes containing the words logical and/or domains:
“Opera, next to Gothic architecture, is one of the strangest inventions of Western man. It could not have been foreseen by any logical process.”
—Kenneth MacKenzie Clark, Baron of Saltwood (19031983)
“I shall be a benefactor if I conquer some realms from the night, if I report to the gazettes anything transpiring about us at that season worthy of their attention,if I can show men that there is some beauty awake while they are asleep,if I add to the domains of poetry.”
—Henry David Thoreau (18171862)
