Availability manager orchestration systems and methods and, particularly, an open resilience framework for simplified and coordinated orchestration of multiple availability managers.

Open resilience framework for simplified and coordinated orchestration of multiple availability managers

An embodiment of the invention is directed to a method associated with a node comprising a hypervisor and guest VMs, each guest VM being managed by the hypervisor and disposed to run applications, the node being joined with other nodes to form an HA cluster. The method includes establishing an internal bidirectional communication channel between each guest VM and the hypervisor, and further includes sending commands and responses thereto through the channel, wherein respective commands manage a specified application running on the given guest VM. The messages are selectively monitored, to detect a failure condition associated with the specified application running on the given guest VM. Responsive to detecting a failure condition, action is taken to correct the failure condition, wherein the action includes sending at least one command through the internal channel from the hypervisor to the given guest VM.

Providing application based monitoring and recovery for a hypervisor of an HA cluster

Techniques for constructing and using models in accordance with service level management are disclosed. In one aspect of the invention, a technique for constructing a model (e.g., a system model) representative of a resource for use in managing a service associated with the resource, comprises the following steps/operations. A set of resource metrics is obtained in accordance with a resource abstract model (RAM) associated with the resource. Then, a model representative of the resource is constructed based on at least a portion of the set of resource metrics obtained from the resource abstract model.

Methods and systems for model-based management using abstract models

A method for evaluating a virtual machine, the method includes: monitoring, using an out of band monitor, information exchanged between the virtual machine and a hypervisor; and evaluating a state of the virtual machine by applying a statistical classification process to at least a portion of the monitored information.

System, method and computer program product for evaluating a virtual machine

A method for generating reference state information, the method includes: comparing between at least one sequence of block identifiers that are accessed during a test period and at least one corresponding reference sequence of block identifiers to provide a comparison result; determining whether to generate reference state information in response to the comparison result; and generating reference state information if determining to generate the reference state information.

Reference state information generation

Techniques are provided for generically controlling one or more resources associated with at least one computing system. In one aspect of the invention, the technique comprises evaluating one or more performance metrics associated with the one or more resources given one or more configurations of the one or more resources. The technique then causes a change in the one or more configurations of the one or more resources based on the performance metric evaluating step. The one or more performance metrics and the one or more configurations are expressed in generic formats.
