This patent application is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to a computer program product, system, and method for modifying an assignment of nodes to roles in a computing environment.
"Cloud storage refers to data storage as a service where storage resources are provided to clients on demand. Cloud storage infrastructures support a multitude of users and services over geographically distributed storage areas. Nodes implementing the cloud storage infrastructure may be assigned certain roles, such as an interface role to provide services to access data in the cloud storage infrastructure from outside the system, a storage role to provide storage services to users, and a management role to manage the cloud storage infrastructure, including the configuration and provisioning of resources and access by users.
"Customers with substantial data storage and access needs are provided a cloud infrastructure having multiple nodes for accessing the data and multiple nodes for reading and writing the data onto the back end storage. The customer may purchase nodes for interface and storage capabilities. As customer needs change, customers may need to purchase more node hardware to expand the interface and storage capabilities."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "Provided are a computer program product, system, and method for modifying an assignment of nodes to roles in a computing environment. There are a plurality of resource thresholds for each of a plurality of roles, wherein each role defines a type of operations and node resource usage for the nodes, and a measurement of node resource usage for the nodes. For at least one of the node, operations are performed comprising: determining at least one of the roles assigned to the node; determining a role resource threshold for each role assigned to the node; determining whether the measured node resource usage at the node exceeds the determined role resource thresholds for each role assigned to the node, wherein the role having the determined resource threshold exceeded by the node resource usage comprises a role to adjust; and determining a modification of the assignment of nodes to the role to adjust.
