Query: Sapphire: Automatic Configuration Recommendation for Distributed Storage
  Systems   Modern distributed storage systems come with aplethora of configurable
parameters that controlmodule behavior and affect system performance. Default
settings provided by developers are often suboptimal for specific user cases.
Tuning parameters can provide significant performance gains but is a difficult
task requiring profound experience and expertise, due to the immense number of
configurable parameters, complex inner dependencies and non-linearsystem
behaviors. To overcome these difficulties, we propose an automatic
simulation-based approach, Sapphire, to recommend optimal configurations by
leveraging machine learning and black-box optimization techniques. We evaluate
Sapphire on Ceph. Results show that Sapphire significantly boosts Ceph
performance to 2.2x compared to the default configuration.
