TBBT: Scalable and Accurate Trace Replay
for File Server Evaluation
Ningning Zhu, Jiawu Chen, and Tzi-Cker Chiueh, Stony Brook University
This paper describes the design, implementation, and
evaluation of TBBT, the first comprehensive NFS trace
replay tool. Given an NFS trace, TBBT automatically
detects and repairs missing operations in the trace, derives
a file system image required to successfully replay
the trace, ages the file system image appropriately, initializes
the file server under test with that image, and finally drives the file server with a workload that is derived
from replaying the trace according to user-specified parameters.
TBBT can scale a trace temporally or spatially
to meet the need of a simulation run without violating
dependencies among file system operations in the trace.
