  • Publication number: 20140337471
    Abstract: A system for assisting migration between first and second information processing systems includes a table retaining communication information on communication between first nodes constituting the first information processing system; a table retaining a design requirement being a condition for a second node constituting the second information processing system; an identifier configured to identify the communication information on the first node which is to be migrated; a comparator configured to acquire the design requirement associated with the identified communication information; a mapper configured to determine based on the design requirement whether addition or deletion of the second node is necessary or not; and a generator configured to generate tenant design properties based on the determination on whether addition or deletion is necessary or not, the tenant design properties being information necessary for the migration and containing a configuration of the second node constituting the second informat

  • 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.

  • Publication number: 20140289404
    Abstract: (1) A configuration management in a management server is carried out such that setting patterns regarding creation of plural types of virtual resources and setting patterns regarding connection between the plural types of virtual resources are extracted from setting information of network devices configuring a virtual network by using plural types of virtualization technologies, (2) an ID required for creating a virtual resource and a connection relation between virtual resources are extracted from the extracted setting pattern, (3) an element corresponding to a virtual resource or a connection between a pair of virtual resources is created by using information including the extracted ID, and (4) the elements created from setting information of individual devices are aggregated to thereby create logical topology information representing a topology of the virtual network.

  • Publication number: 20140010109
    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: 20120311120
    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.
