A virtualization infrastructure that allows multiple guest partitions to run within a host hardware partition. The host system is divided into distinct logical or virtual partitions and special infrastructure partitions are implemented to control resource management and to control physical I / O device drivers that are, in turn, used by operating systems in other distinct logical or virtual guest partitions. Host hardware resource management runs as a tracking application in a resource management “ultravisor” partition, while host resource management decisions are performed in a higher level command partition based on policies maintained in a separate operations partition. The conventional hypervisor is reduced to a context switching and containment element (monitor) for the respective partitions, while the system resource management functionality is implemented in the ultravisor partition. The ultravisor partition maintains the master in-memory database of the hardware resource allocations and serves a command channel to accept transactional requests for assignment of resources to partitions. It also provides individual read-only views of individual partitions to the associated partition monitors. Host hardware I / O management is implemented in special redundant I / O partitions. Operating systems in other logical or virtual partitions communicate with the I / O partitions via memory channels established by the ultravisor partition. The guest operating systems in the respective logical or virtual partitions are modified to access monitors that implement a system call interface through which the ultravisor, I / O, and any other special infrastructure partitions may initiate communications with each other and with the respective guest partitions. The guest operating systems are modified so that they do not attempt to use the “broken” instructions in the x86 system that complete virtualization systems must resolve by inserting traps. System resources are separated into zones that are managed by a separate partition containing resource management policies that may be implemented across nodes to implement a virtual data center.

In accordance with an exemplary embodiment of the present invention, association forming entities are: a) maintained as objects in a like manner to the data objects being associated; and 6) are themselves partitioned objects comprising two or more association fragments, each association fragment being mostly concerned with the interfaces to a particular data object participating in the association. In accordance with an exemplary embodiment of the present invention, each association fragment affiliated with a particular data object is stored in a location that enhances the ease of interaction between the association fragment and the data object. For example, where a first data object and second data object are maintained in data stores at some distance from one another, physically or logically, then a first association fragment will be located with or near to the first data object and a second association fragment will be located with or near the second data object, at least within the same partition. This arrangement may be preferable because the volume of interaction between a data object and its respective association fragment may far outweigh the interaction needed between the two association fragments. This arrangement may also be preferable as the volume of interaction between a client application and both the data object and respective association fragment may exceed the interaction needed between the two association fragments. Some interactions will employ only one of the association fragments with the net result being a reduction in communications requirements and an improvement in performance. The present invention further provides for defining logical domains which are arbitrary and entirely orthogonal to partitions.
