Currently, resource allocation to applications in state- of-the-art platforms occurs through different perfor- mance optimization loops, run independently at dif- ferent levels of the software stack, such as, at the database server, operating system and storage server, in the consolidated storage environment shown in Figure 1. Each local controller typically optimizes its own local goals, e.g., hit-ratio, disk throughput, etc., oblivious to application-level goals. This might lead to situations where local, per-controller, resource allocation optima do not lead to the global optimum; indeed local goals may conﬂict with each other, or with the per-application goals [14]. Therefore, the main challenge in these mod- ern enterprise environments is designing a strategy which adopts a holistic...
