  • Patent number: 10789106
    Abstract: A virtual machine is assigned to a target physical server based on virtualization parameters for maximizing utility of a multiple virtual machines and physical servers. Resource allocation is performed for and deployment of the virtual machine to the target physical server based on capabilities of the target physical server and multiple virtual machine resource requirements. The virtualization parameters include a minimum parameter, a maximum parameter and a shares parameter. Processing resources are allocated based on utility priority of applications operating on the virtual machine using the shares parameter of contending virtual machines to determine a processing cycle ratio for distributing processing cycles between different utility priority applications operating on the contending virtual machines.

  • Patent number: 10108460
    Abstract: A method and system for integrated server-storage deployment planning for virtual appliances is provided. One implementation involves determining a performance cost in deploying the virtual appliance to different pairings of candidate host and storage subsystems. A host and storage subsystem pair is preferentially selected among the candidate pairings, a pairing of a host and storage subsystem with certain performance cost to satisfy performance requirements of the virtual appliance. Deployment planning may further involve deploying a virtual appliance on one or more appropriate spatially proximate hosts and storage subsystems that exhibit certain preferable connectivity and path capacity to satisfy the performance requirements of the virtual appliance.

  • Patent number: 9740365
    Abstract: A method, system, and computer program product for visualization-centric performance-based volume allocation in a data storage system using a processor in communication with a memory device is provided. A unified resource graph representative of a global hierarchy of storage components in the data storage system, including each of a plurality of storage controllers, is generated. The unified resource graph includes a common root node and a plurality of subtree nodes corresponding to each of a plurality of nodes internal to the plurality of storage controllers. The common root node and the plurality of subtree nodes are ordered in a top-down orientation. Scalable volume provisioning of an existing or new workload amount by graphical manipulation of at least one of the storage components represented by the unified resource graph is performed based on an input.

  • Patent number: 8909890
    Abstract: A scalable, performance-based, volume allocation technique that can be applied in large storage controller collections is disclosed. A global resource tree of multiple nodes representing interconnected components of a storage system is analyzed to yield gap values for each node for a specific time period. The gap value for each node is an estimate of the amount of the additional or increased workload that can be allocated in the subtree of that node without exceeding the performance and space bounds at any of the nodes in that subtree for the specific time period. The gap values of the global resource tree are further analyzed to generate an ordered allocation list of the volumes of the storage system.

  • Patent number: 8682850
    Abstract: A method and apparatus are provided for enhancing the impact of data de-duplication by preferential selection of the master copy to be retained based on current loads and performance metrics of the storage media devices. The computer system is configured to take as input the identified duplicate copies of data and evaluating their locations in storage devices to determine the cumulative affects of retaining one of the identified duplicate copies as a master copy and optionally allocating a new location if needed. Once a master copy has been designated, the remaining identified duplicate copies are removed from storage.

  • Patent number: 8412890
    Abstract: A scalable, performance-based, volume allocation technique that can be applied in large storage controller collections is disclosed. A global resource tree of multiple nodes representing interconnected components of a storage system in a plurality of component layers is analyzed to yield gap values for each node (e.g., a bottom-up estimation). The gap value for each node is an estimate of the amount in GB of the new workload that can be allocated in the subtree of that node without exceeding the performance and space bounds at any of the nodes in that subtree. The gap values of the global resource tree are further analyzed to generate an ordered allocation list of the volumes of the storage system (e.g., a top-down selection). The volumes may be applied to a storage workload in the order of the allocation list and the gap values and list are updated.

  • Patent number: 8341623
    Abstract: A storage placement planning system receives a resource graph describing SAN's resources and virtual machine applications requiring a particular amount of a processing resource element and a storage resource element. The system then determines a coupled placement of the processing element and storage element for each of the applications on a coupled pair of the resource nodes based on a specified throughput and a distance factor between coupled pairs of resource nodes. The coupled placement is determined using an algorithm that implements a cost function that determines affinities between processing nodes and storage nodes for each of said applications of a particular workload. The coupled placement for each of said applications identifies the particular amount of processing resource element placed on a first node for providing a processing resource and the particular amount of storage resource element placed on a second node for providing a storage resource for that application.

  • Patent number: 8321396
    Abstract: A by-line extraction system detects a set of potential headlines from a title meta-tag of a crawled document, selects a candidate headline from the set of potential headlines, and extracts the by-line information from the document using the location of the selected candidate headline. The system constructs the set of potential headlines based on the title meta-tag. The system selects a candidate headline by evaluating the set of potential headlines in order of the lengths of the potential headlines. The system extracts the by-line information from the document by using the location of the selected candidate headline to extract a string representing a date, a name, or a source located within a minimum distance from the location of the potential headline.
