Timing-accurate storage emulation fills an important gap in the set of common performance evaluation techniques for proposed storage designs: it allows a researcher to experiment with not-yet-existing storage components in the context of real systems executing real applications. As its name suggests, a timing-accurate storage emula- tor appears to the system to be a real storage component with service times matching a simulation model of that component. This paper promotes timing-accurate stor- age emulation by describing its unique features, demon- strating its feasibility, and illustrating its value. A pro- totype, called the Memulator, is described and shown to produce service times within 2% of those computed by its component simulator for over 99% of requests. Two sets of measurements enabled by the Memulator illus- trate its power: (1) application performance on a modern Linux system equipped with a MEMS-based storage de- vice (no such device exists at this time), and (2) appli- cation performance on a modern Linux system equipped with a disk whose firmware has been modified (we have no access to firmware source code). |
