  • Patent number: 10983882
    Abstract: Example implementations described herein are directed to systems and methods involving an application running on a host computer and configured to manage storage infrastructure. The application not only manages resources already allocated to itself, but also manages the allocation and de-allocation of resources to itself. The resources can be allocated and de-allocated based on the type of process being executed, wherein upon occurrence of a failure on a primary storage system, higher priority processes that are executed on connected failover storage system nodes are given priority while the lower priority processes of such failover storage system nodes are disabled.

  • Publication number: 20210105181
    Abstract: Visibility of relevance of detailed configurations is improved while deterioration of the visibility of a general configuration between nodes is suppressed. A node coordinate calculation process calculates, upon calculation of deployment coordinates of each node, a degree of importance of an infrastructure resource and a degree of importance of an application, and weights the distance between the application node and the infrastructure node with the reciprocal of the degree of importance of the infrastructure node. Then, the node coordinate calculation process determines deployment of the application node such that the application node is deployed in the proximity of a comparatively important infrastructure node, and determines deployment of the application node on the basis of the degrees of importance of the applications such that a comparatively important application is deployed closely to the infrastructure node.
