    摘要: Configuration requirements for an Availability Management Framework (AMF) configuration are generated from high level user requirements that specify a subset of properties of an AMF configuration. The user requirements are first mapped into entity prototypes defined in an extended Entity Types File (ETF) model. A computer system identifies additional entity prototypes and dependency thereof that support functionalities of the mapped entity prototypes under a set of grouping conditions. The computer system calculates the required number of component service instances (CSIs) and service instances (SIs) that satisfy the user requirements. The calculation is based on the subset of the properties specified by the user requirements and measurements associated with the entity prototypes in the extended ETF model. The computer system then forms configuration requirements including the required number of CSIs and SIs for generating the AMF configuration that satisfies the user requirements.

    摘要: An Availability Management Framework (AMF) configuration describes how configuration entities of a highly available system are grouped and includes information on service provision and service protection policies against resource failure. The AMF configuration defines a set of failure types for each component and each node, and specifies a failure rate and a recommended recovery for each failure type. A method for evaluating service availability receives the AMF configuration as input, and analyzes it to obtain an actual recovery that the highly available system is to perform when the given component fails. The method maps the AMF configuration to a stochastic model that captures the dependencies among the components and among the configuration entities at multiple levels of the hierarchy. The method utilizes the model to calculate the service availability of the AMF configuration based on the failure rate, the actual recovery and the dependencies.

    摘要: Among other things, embodiments described herein enable systems, e.g., Availability Management Forum (AMF) systems, having service units to operate with balanced loads both before and after the failure of one of the service units. A method for balancing standby workload assignments and active workload assignments for a group of service units in a system which employs an N+M redundancy model, wherein N service units are active service units and M service units are standby service units is described. An active workload that the N active service units need to handle is calculated and each of the N active service units in the group is provided with an active workload assignment based on the calculated active workload. Standby workload assignments are distributed among the M standby service units substantially equally.

    摘要: Among other things, embodiments described herein enable systems, e.g., Availability Management Forum (AMF) systems, having service units to operate with balanced loads both before and after the failure of one of the service units. A configuration can be generated which provides for distributed backup roles and balanced active loads. When a failure of a service unit occurs, the active loads previously handled by that service unit are substantially evenly picked up as active loads by remaining service units.

    摘要: Redundancy models are compared to determine or assist in determining an Availability Management Framework (AMF) configuration of a highly available system based on quantified service availability of the system. Each redundancy model defines assignments of service-instances to service-units. An analysis model of the system is constructed to capture recovery behaviors of the system for each redundancy model. Service availability of the system is quantified based on the analysis model under one or more scenarios including failure scenarios and recovery scenarios. Based on a comparison of service availability levels provided by the redundancy models and subject to constraints of the HA system, one of the redundancy models is identified that provides a required level of service availability for the system.
