Abstract: A data center network flow migration method includes detecting a utilized loading value in each switch of a plurality of switches in the data center network by a controller according to topology information of the data center network. The controller re-establishes a plurality of link paths corresponding to the plurality of switches in the data center network according to the utilized loading value in each switch and a disjoint edge node divided spanning tree algorithm. In these re-established link paths corresponding to the plurality of switches in the data center network, if the utilized loading value of at least one link path is greater than a threshold value, the at least one link paths with the utilized loading value greater than the threshold value is rerouted by a controller according to a flow migration algorithm.

Abstract: Data center network provisioning method includes partitioning a plurality of virtual machines in the data center network into a plurality of groups according to topology information of data center network. A plurality of virtual machines in each group is assigned to a plurality of servers in the data center network. A pair-wised transmission path of the plurality of servers is assigned according to a traffic load of each switch in the data center network.

Abstract: A method of resource allocation in a server system includes predicting a resource requirement of an application by adopting a neural network algorithm. When the resource requirement of the application is greater than a virtual machine allocation threshold, turn on a virtual machine for the application and adjust the value of the virtual machine allocation threshold to be the sum of the virtual machine allocation threshold and a resource capacity of the virtual machine.

Abstract: An expansion device for storage units is applicable to a data processing system such as a blade server, to allow the number of storage units connected with the expansion device to be adjusted or increased according to user requirements. The expansion device is provided with a first interface connected with the data processing system, and with at least one second interface connected with at least one storage unit. The expansion device further includes a transmitting unit and a switching module for allowing the expansion device to be connected with storage units using different transmitting standards.

Abstract: A backup control system and method includes at least two system control modules and a power supply unit. The system control modules automatically detect the operating conditions of one another according to a determined logic of a backup control method. In the event that one system control module malfunctions, the operating condition is automatically transformed to continuing execute the control process and to enable that the power supply unit provides dynamically electric power according to loadings of the backup control system. Further, each system control module can automatically and immediately replace the other system control module to execute control processes and maintain the electronic equipment working, thereby reducing waste of electric resources.
