This paper presents Q-OPT, a system for automatically tuning the configuration of quorum systems in strongly consistent Software Defined Storage (SDS) systems. Q-OPT is able to assign different quorum systems to different items and can be used in a large variety of settings, including systems supporting multiple tenants with different profiles, single(More)
