Patent number: 11556383Abstract: To more properly size resources in a destination to which IT resources will be migrated, a system for appraising a resource configuration estimates a source's load model representing a load of first resources in a first computer system which is the source of migration and estimates a destination's load model representing a load of second resources to be built by migrating the first resources to a second computer system based on the source's load model. The system compares performance requirements of the first resources against the destination's load model and finds the destination's load model that is conformable to the performance requirements. When determining design values of the second resources' configuration, the system corrects those design values based on the destination's load model estimated conformable to the performance requirements to decrease design margins of the resource configuration using a design correction value defined to meet a service level requested.Type: GrantFiled: February 26, 2021Date of Patent: January 17, 2023Assignee: HITACHI, LTD.Inventor: Atsumi Terayama

Patent number: 9575798Abstract: A non-virtual server and a virtual server make up the same tenant in an environment, in which virtual servers created by dividing a single physical server into a plurality of computer environments coexist with a non-virtual server that directly uses a single physical server as a computer environment without using server virtualization. A management computer is provided with virtual switch management information that shows a correlation between the virtual servers and an internal network to which a relevant virtual server connects, and physical switch management information that shows a correlation between the non-virtual server and an internal network to which the non-virtual server connects. The management computer creates a virtual server that belongs to the same tenant as a physical instance, identifies a first internal network to which the non-virtual server connects, and configures the tenant so that the relevant virtual server is connected to the first internal network.Type: GrantFiled: February 25, 2013Date of Patent: February 21, 2017Assignee: Hitachi, Ltd.Inventors: Atsumi Terayama, Toshio Otani, Akihisa Nagami
