Overview: This paper published by Institute of Electrical and Electronics Engineers describes that Self-systems are self-organizing, self-configuring, self-healing, self-tuning and, in general, self managing. Ursa Minor is a large-scale storage infrastructure being designed and deployed at Carnegie Mellon University, with the goal of taking steps towards the self-ideal. This paper discusses the early experiences with one specific aspect of storage management: performance tuning and projection. Ursa Minor uses self-monitoring and rudimentary system modeling to support analysis of how system changes would affect performance, exposing simple What if query interfaces to administrators and tuning agents.
