File systems are very important components in a computer system. File system simulation can help to predict the performance of new system designs.
It offers the advantages of the flexibility of modeling and the cost and time savings of utilizing simulation instead of full implementation. Being able to predict end-to-end file system performance against a pre-defined workload can help system designers to make decisions that could affect their entire product line, involving several million dollars of investment.
This dissertation presents detailed simulation-based performance models of the Linux ext3 file system and the PVFS parallel file system. The models are developed using Colored Petri Nets.
A performance study, using the models, shows that the obtained results are close to the expected behavior of the real file system. Location of Repository.
