Abstract. Due to the imperative need to reduce the costs of manage-
ment, power and cooling in large data centers, operators multiplex sev-
eral concurrent applications on each physical server of a server farm
connected to a shared network attached storage. Determining and en-
forcing per-application resource quotas on the fly in this context poses a
complex resource allocation and control problem spanning many levels
including the CPU, memory and storage resources within each physical
server and/or across the server farm. This problem is further complicated
by the need to provide end-to-end Quality of Service (QoS) guarantees
to hosted applications.
In this paper, we introduce a novel approach towards controlling applica-
tion interference for resources in shared server farms. Specifically, we de-
sign and implement a minimally intrusive method for passing application-
level QoS requirements through the software stack. We leverage high-
