Extension FAQ

  • What is a benchmark extension?

    Benchmark extensions are optional additions to an existing benchmark that are designed to showcase a feature or set of features, and to provide vendors with a means to differentiate their products across dimensions other than the existing performance or price-performance metrics of the benchmark.

  • Is this extension part of the GoldStar program?

    Yes, This is one of the five extensions included in the initial release of the GoldStar program.

  • Are the snapshots application consistent?

    This test is limited to crash-consistent snapshots, which provide an image of a storage system and the data it manages at the time that the snapshot is taken. An assessment of application-consistent snapshots would require the modeling of an explicit application context, and is beyond the scope of SPC benchmarks.
