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.

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.

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.

In one embodiment, a method for workload management using instant capacity (iCAP) processors comprises generating performance data related to workloads on multiple servers, determining processor resources appropriate for the workloads using the performance data, communicating a request from a first server to reallocate processor resources in response to the determining, deactivating at least one iCAP processor on a second server in response to the request, and activating at least one iCAP processor on the first server in conjunction with the deactivating.

In one embodiment, a system comprises a plurality of partitions that provide isolated operating environments for execution of software processes, wherein the plurality of partitions are arranged in a tiered manner with different partition types at different tiers, a data structure for representing the plurality of partitions, wherein the data structure comprises multiple nodes corresponding to the plurality of partitions and links between the nodes representing how the plurality of partitions are arranged in the tiers, and an arbiter software module for allocating resources between the plurality of partitions, wherein the arbiter software module receives requests to allocate resources to the plurality of partitions and traverses the data structure to determine which requests to satisfy.

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.
摘要:
A virtual machine (VM) is created using an alternate root disk (DRD) that has complete isolation between the booted system environment (BSE) running on the host operating system and the BSE running on the VM's operating system. The VM's root disk and BSE are separately bootable from the host system's root disk and BSE, thereby allowing for updates and modifications to the VM's root disk and BSE without interference with the host system's root disk and BSE regardless of how many times the updating BSE must be rebooted during the updating procedure. At most a single reboot is required in order to transfer the work in progress from the VM to the host system.
