  • Patent number: 9647910
    Abstract: Methods and apparatuses for managing a service system virtually built are provided. A management server assigns identifiers that are unique to a service system to components used to build the service system, and records connections of the components and the time of building the service system. When detecting a change in the connections of the components, the management server records the changed connection and the time of the change, collects monitoring information and monitoring times from a data center, and records the monitoring information associated with the monitoring times. When receiving information designating a time from a terminal, the management server identifies and outputs the configuration of the service system and the monitoring information at the designated time based on the identifiers of the components associated with the designated time.

  • Patent number: 9207939
    Abstract: There is a need for providing the Xeon CPU with a two-level VM that is independent of VMM types and prevents the throughput from degrading when the OS operates the privilege register. A machine is provided with a processor and memory. The machine includes a first virtual machine manager for managing a virtual machine, a second virtual machine for managing an operating system, first management information, and second management information. The processor is provided with a register and a shadowing function. The machine uses a virtualization method. The first virtual machine manager detects a call from the second virtual machine manager. The first virtual machine manager enables the shadowing function when it is determined that an instruction for enabling the shadowing function caused the call.

  • Publication number: 20150280987
    Abstract: In a multi-tenant information processing system, when initially constructing a tenant, design items depending on the tenant are specified for each device constituting the tenant, and design values of the design items are calculated without overlapping with those of other tenants. In a tenant design item management table, the design items set for the devices and information indicating whether the design items depend on the tenant, are stored for each device. In a design algorithm management table, calculation formulae for making the design values to be different for each tenant are stored corresponding to the design items. A tenant design unit refers to the tenant design item management table, specifies the design items depending on the tenant among those corresponding to the devices constituting the tenant, calculates the design values of the design items according to the calculation formula, when initially constructing the tenant.

  • Patent number: 9137118
    Abstract: To identify a logical topology of each virtual network among logical topologies of a plurality of virtual networks configured in physical devices. A management server includes a controller for managing logical topology information of all virtual networks each of which includes a plurality of virtual resources configured in a plurality of physical devices coupled to a network; wherein the controller: searches the logical topology of all the virtual networks from the entire virtual network based on the information of branch point resource which is a kind of virtual resource for mutually coupling the plurality of virtual networks and constitutes a branch point for each virtual network; extracts a series of virtual resources that terminates at the branch point resource; and identifies the series of extracted virtual resources as a partial topology, which eventually represents the topology of a virtual network inside the entire virtual network.

  • Publication number: 20140317313
    Abstract: In a network where network address translation (NAT) has been introduced, a problem occurs in which, when an IP host operating in a network is automatically categorized with automatic IP host discovery using an ARP cache, a plurality of IP hosts with the same IP address are recognized as one IP host by NAT. To resolve this problem, a network management server specifies network sub-topology on the basis of topology information, public addresses translated by NAT, and IP host corresponding relationships.
