  • Patent number: 9130850
    Abstract: A monitoring system is configured to perform a cause analysis of an event which occurs in any of a plurality of node apparatuses. The monitoring system is configured to store a plurality of rules indicating a correspondence relationship between one or more condition events regarding any of the plurality of node apparatuses, and a conclusion. The monitoring system is configured to specify the first conclusion associated with the detected condition event based on the rule, and perform a detection possibility judgment on whether the monitoring system can detect the condition event or not, for each of one or more condition events out of a plurality of condition events, and calculate the first index value indicating the certainty of the first conclusion being the cause, based on the existence of detection of one or more condition events associated with the first conclusion and the result of the detection possibility judgment.

  • Publication number: 20150234671
    Abstract: A management system is able to reduce a migration load, which is associated with a requested change in a system which receives a virtual machine generation request that designates a template. The system searches for a physical computer having physical resources included in the template, sends a resource allocation request to the searched physical computer in accordance with the received virtual machine generation request and the template, collects a resource usage status of each physical computer, receives an identifier of a generated virtual machine and a change request to change the template. Then, the system calculates a resource type and resource amount, which need to be added by changing the template, based on the collected resource usage status; and determines whether a first physical computer for controlling the generated virtual machine has the additional resource amount of the calculated resource type as an unused resource amount or not.

  • Patent number: 9021078
    Abstract: The management system identifies a first event regarding a first node apparatus estimated to occur when a first maintenance work is performed on a first node apparatus based on maintenance work information that indicates a correspondence relationship between each maintenance work of one or more maintenance works for any of the plurality of node apparatuses and an event regarding a node apparatus to be the target of each maintenance work, which is estimated to occur when the maintenance work is performed. The management system identifies the range of effect and phenomenon of the case where the first maintenance work is performed on the first node apparatus, by performing simulation based on one or more rules indicating a correspondence relationship between one or more conditional events and a causal event and displays the identified range of effect and phenomenon.

  • Patent number: 8656011
    Abstract: A management apparatus stores attribute/protocol management information denoting each attribute/protocol relationship. The management apparatus, for each of multiple addresses prior to inputting the credential used to detect the communication apparatus, (A) issues a query that specifies an address, (B) upon receiving a response to this query from the communication apparatus at the address specified in this query, writes, to a storage resource, query result information denoting the corresponding relationship between the address specified in this query and the communication apparatus attribute acquired based on the response, (C) identifies the management protocol corresponding to the communication apparatus attribute denoted by the query result information from the attribute/protocol management information, and (D) decides the optimum management protocol for the address based on the identified management protocol.

  • Publication number: 20130080604
    Abstract: The present invention is for efficiently managing large numbers of apparatuses using multiple management protocols. A management information acquisition part 1A uses multiple different management protocols P1 and P2 to acquire management information for each of the management protocols from each apparatus 3. Anode configuration information management part 1B identifies apparatus configuration information acquired from the same apparatus of the respective apparatuses 3 by comparing the apparatus configuration information, and collectively manages these multiple pieces of apparatus configuration information as a single piece of apparatus configuration information. A component information management part 1C identifies multiple pieces of component information related to the same component, and manages these identified multiple pieces of component information after associating these pieces information with each other.

  • Patent number: 8209511
    Abstract: A storage management apparatus performs migration considering an I/O load that will be generated during migration between a source array group and a destination array group. To migrate data from the source array group to the destination array group, a bandwidth that is available for use between the source and destination array groups is calculated. A volume that is within the source array group, and that has a write I/O amount that is smaller than the calculated bandwidth, is selected as the source volume for the migration, wherein the write I/O amount is the information transmission amount of information that is written. Data is thus migrated from the selected volume to the movement destination array group.
