Abstract

A computer server comprises: a CPU pool comprising a plurality of CPUs (Central Processing Units); two or more partitions for allocating the plurality of CPUs in a mutually exclusive fashion and running operating systems (OS) independently from each other; and a resource managing and monitoring unit for CPU allocation and recovery in each of the two or more partitions, based on the number of CPUs currently available and the number of CPUs currently in use. The resource managing and monitoring unit monitors partition status data (which includes data relating to the number of CPUs currently in use, the number of CPUs secured, the capping state, and the maximum number of available CPUs) in order to measure the percentage of CPU resources used in each of the two or more partitions.

Description

technical field [0001] The present invention relates to a computer server, and more particularly, to a computer server capable of supporting CPU (Central Processing Unit) virtualization. Background technique [0002] Recently, computer servers can execute various operating systems in a single piece of hardware through CPU (Central Processing Unit) virtualization. A partition can be defined as a unit for independently executing an operating system. In CPU virtualization, computer servers become less efficient when CPU usage is not accurately measured. SUMMARY OF THE INVENTION [0003] In some embodiments, a computer server includes: a CPU (Central Processing Unit) pool including a plurality of CPUs; at least two partitions provided exclusively with the plurality of CPUs and independently executing an operating system; and a resource management and monitoring unit that manages CPU allocation and retrieval for at least two partitions based on the number of currently availab...
