Multiplex File System (MPFS) is a new network file access protocol that allows heterogeneous hosts to access the shared data. The MPFS split data-metadata architecture demands new ways to evaluate performance. Current I/O benchmarks are not suitable to measure the performance of MPFS because they mainly measure the performance of NFS or CIFS. We develop a new benchmark that can measure the performance of MPFS for a variety of applications. Our benchmark uses a series of application groups to mimic the real-world applications that use MPFS. The mix of these application groups generates the workload to stress the MPFS system.
Based on our MPFS benchmark, we develop a MPFS Performance Monitor for EMC Celerra File Server (CFSPM). CFSPM is a benchmark program to measure the performance of Celerra File Server under MPFS protocol with a web-based interface. A series of MPFS performance data colleted from CFSPM is presented and analyzed in the thesis. We find that the CFSPM benchmark does meet the criteria we apply to the ideal MPFS benchmark.
