Abstract: Increased workload performance is obtained by coordinating a multi-resource computer system such that demands for resources are arbitrated across all available resources and all applications such that the proper resource will be adjusted regardless of which resource is needed to improve workload performance. In operation, a measurement is taken for each available resource to determine the enhancement achieved by adding a certain quantity of a resource. In one embodiment, resource consumption and performance data is collected over a period of time and that data is used to adjust resource requests for a workload in order to improve the workload's performance. The resource request is modified to deliver the most workload benefit for each resource modification.

Abstract: The present invention provides for redistributing workloads among computers to optimize resource utilization. Utilization by software workloads of computer resources is monitored to yield utilization data. A utilization chronology is updated using the utilization data. The chronology is analyzed to yield resource utilization predictions. The workloads are redistributed among the resources at least in part as function of said predictions.

Abstract: When a computer system process is acting contrary to the rules established for that process for the resource it is running on, the process is moved to a quarantined section and its continued operation is isolated from other processes. While in isolation, the quarantined process is tested and appropriate action, such as, for example, rehabilitation, change of the rules, or termination, is performed. The divided quarantined sections are used for each misbehaving process.

Abstract: Systems and methods are disclosed in which the software license for server partitions are flexible in that, as between two (or more, if desired) partitions the software licensed resources assigned to one partition can be used by the other partitions, providing a total number of resources do not exceeded the software license limit. In one embodiment, a workload manager monitors workload utilization to be sure that the total number of CPUs working on the application does not exceed the maximum under the software license. Users are notified when the workload's policy is about to be exceeded. In one embodiment, this could be a warning while in another embodiment additional software licenses can be activated, or a limit can be placed on the CPU use.

Abstract: In one embodiment, a method comprises executing a plurality of virtual machines on a plurality of nodes of a cluster computing system, wherein at least one application is executed within each of the plurality of virtual machines, generating data that is related to performance of applications in the virtual machines, analyzing, by a management process, the data in view of parameters that encode desired performance levels of applications, and migrating, by the management process, a virtual machine on a first node to a second node of the plurality of nodes in response to the analyzing.

Abstract: In one representative embodiment, a system for operating load balancers for multiple instance applications comprises a plurality of cluster nodes for executing applications, wherein at least a subset of the plurality of cluster nodes executes multiple applications and includes respective resource allocation modules for assigning resources between the multiple applications in response to performance data associated with the multiple applications, a plurality of load balancers for distributing application transactions between the plurality of cluster nodes, and a configuration process that analyzes performance data associated with the multiple applications and dynamically configures the plurality of load balancers in response to the analysis.

Abstract: Systems and methods are disclosed for dynamic management of workloads in clusters. In one embodiment, the system comprises a first cluster comprising a first plurality of nodes, each node of the first plurality of nodes including a first application, and a first load balancer to route transactions for the first application to one of the first plurality of nodes. The system also comprises a second cluster comprising a second plurality of nodes, each node of the second plurality of nodes including a second application, and a second load balancer to route transactions for the second application to one of the second plurality of nodes. One or more intersecting nodes are included in the first and second plurality of nodes, each intersecting node including one or more workload managers to dynamically allocate one or more computer resources to the first application and the second application.
