The purpose of StorPerf is to provide a tool to measure block and object storage performance in an NFVI. When complemented with a characterization of typical VF storage performance requirements, it can provide pass/fail thresholds for test, staging, and production NFVI environments.

The benchmarks developed for block and object storage will be sufficiently varied to provide a good preview of expected storage performance behavior for any type of VNF workload. The elements of the project include:

• Test Case definition
• Metrics definition
• Test Process definition
• Tool development

Some of these are expanded further below.

• Meetings: TBD
• Original etherpad proposal: https://etherpad.opnfv.org/p/StorageBenchmarkProposal
• Jira: TBD
• Gerrit: TBD
• Git: TBD

StorPerf testing addresses both block storage and object stores, though using different test suites. There is limited value in testing locally attached storage, so this is primarily about testing distributed/external storage environments.

There are three applicable use cases for these storage performance benchmarks:

1. An OPNFV test lab manager wants to characterize expected storage behavior in a test NFVI deployment. This will include both a preconditioning phase for each storage environment as well as the broadest set of test cases across all identified storage services. This will provide VNF test applications with information about expected storage performance. This will integrate with existing test lab tool chains.
2. A Service Provider wants to validate storage performance in an NFVI staging environment prior to production deployment. This will validate expected performance expectations using pass/fail conditions using the same preconditioning and test cases as for a test lab. This will integrate with project Bootstrap.
3. A Service Provider wants to isolate performance problems in a production NFVI environment. This will use a much narrower set of test cases to minimize impact on the production environment. This will utilize a manual deployment and control of the test VMs.
