Abstract
Given a multi-component system and a multi-part performability requirement, a method and apparatus for determining whether the system will satisfy the multi-part performability requirement is described. The method uses a failure-scenario generator that analyzes the most-likely failure scenarios first and operates only until a PASS-FAIL determination can be rendered.
Claims21
A method of determining whether a multi-component target system meets a given multi-part performability requirement, the method comprising:
- operating on a representation of the target system, providing a first failure-scenario analysis of said target system,
- generating a multi-part performability function of said target system using said first failure-scenario analysis,
- comparing said multi-part performability function with said multi-part performability requirement, and
- determining from said comparing whether said target system meets said multi-part performability requirement.
A computer memory comprising:
- computer code operating on a representation of the target system, providing a first failure-scenario analysis of said target system;
- computer code providing a first failure-scenario analysis of said target system;
- computer code generating a multi-part performability function using said first failure-scenario analysis;
- computer code comparing said multi-part performability function with said multi-part performability requirements;
- and
- computer code determining from said comparing whether said target system has a capability of performing said multi-part performability requirements.
A method of doing business of verifying performability of a target system having predetermined components and predetermined multi-part performability requirements, the method comprising:
- using a computer,
- (1) operating on a representation of the target system, including providing a failure-scenario analysis of said target system;
- (2) generating a multi-part performability curve using said failure-scenario analysis;
- (3) comparing said requirements with said curve;
- (4) determining from said comparing whether said target system has the capability of performing said multi-part performability requirements;
- and
- (5) generating a report indicating of results whether said target system has the capability of performing said multi-part performability requirements.
A method of reporting performability of a given data storage system under a given system performance requirements specification, the method comprising:
- generating a plurality of failure scenarios indicative of individual component failures;
- determining performance states of said system under each of said failure scenarios;
- comparing a function indicative of said performance states to said system performance requirements specification;
- and
- based on a comparison derived from said step of comparing, reporting whether the performability of the given system meets the given system performance requirements specification.
