Rice University's PhD candidate writes thesis on "Storage virtualization and performance"

He plans to defend it soon. Its actually called : Performance Virtualization and QoS in Shared Storage Systems


This dissertation targets the problem of performance virtualization in shared storage systems. This is motivated by growing trends towards storage consolidation. The goal is to provide performance guarantees to an application irrespective of the behavior of other concurrent workloads. In doing so, we propose QoS scheduling mechanisms for both centrally shared storage systems and distributed storage systems such as FAB and IceCube. QoS and efficiency are two strongly opposing forces when it comes to sharing of I/O devices, and it is a challenge to achieve both simultaneously.
