Oracle Vm Server For Sparc
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 procurement of Sun in January 2010. Oracle VM Server for SPARC was re-branded from version 2.0 onwards.
Each domain can be swiftly migrated between servers without demanding much more efforts and causing interruption, even when the servers are running. This comprehensively virtual machine is incorporated with a reconfigurable subset of hardware resources. All the processes running inside Logical Domains can be rebooted, stopped, or resumed independently.
Moreover, dynamically reconfigured domain does not demand a reboot. One can easily add or remove CPUs, I/O devices, RAM, without preparing for reboot.
Usually, all the logical domains are similar in nature and function as per the assigned work, such as control domain, root domain, guest domain, service domain, I/O domain, and so on.
Consolidation of up to 128 virtual machines on one SPARC server:
- Enhanced efficiency
- Instant and secure live migration between hosts
- Completely dynamic resource management of memory, virtual I/O, CPU, and crypto accelerators on running virtual machines
- Fully-automated CPU dynamic resource management, which directs the resources where they are required the most
- Redundant virtual networks and disks that ensures higher availability
