Oracle VM Server for SPARC (previously called Sun Logical Domains, or LDoms) is Oracle's server virtualization and partitioning technology on Oracle's SPARC servers. Oracle VM Server for SPARC leverages the SPARC hypervisor to subdivide supported platforms' resources (CPUs,memory, I/O, and storage) by creating partitions called logical or virtual machines to take advantage of the massive thread scale offered by SPARC servers and the Oracle Solaris operating system. And all this capability is available at no additional cost.
Where to Start
Oracle offers a full portfolio of virtualization solutions to address your needs. SPARC is the leading platform to have the dynamic domain capability that provides the physical isolation needed to run independent operating systems. Many customers have already used Oracle Solaris Containers for application isolation.Oracle VM Server for SPARC provides another important feature with OS isolation. This gives you the flexibility to deploy multiple operating systems simultaneously on a single SPARC T-Series server with finer granularity for computing resources. For SPARC T-Series processors, the natural level of granularity is an execution thread, not a time-sliced microsecond of execution resources. Each CPU thread can be treated as an independent virtual processor. The scheduler is built into the CPU, without the extra overhead for scheduling in hypervisor. What you get is a lower overhead and higher performance virtualization solution.
