TOS Block Analysis

This project refers to the paper: An In-Depth Comparative Analysis of Cloud Block Storage Workloads: Findings and Implications.

Preface

This repository contains the following folders:

• src: The C++ source code of our analysis
• r: The R scripts for further processing and plotting
• etc: Property files we use during analysis

When we run the analysis, these directories can be created:

• bin: The executables of the analyze scripts
• result: The results generated by analyze*.cc files
• processed: The results further processed by process*.cc files
• figure: The figures generated by the R scripts

Run the analysis

• Download the AliCloud traces from https://github.com/alibaba/block-traces
• Download the TencentCloud traces from http://iotta.snia.org/traces/27917
• Download the MSRC traces from http://iotta.snia.org/traces/388
• Modify scripts/common.sh to specify the paths of AliCloud, TencentCloud, and MSRC traces
  • And also the paths of storing the final traces files (separated by volumes)
• Run prepare.sh to:
  • split the AliCloud and TencentCloud traces into csv files, divided by the volume names
  • check whether all the trace files are ready
• Run run.sh to analyse the traces and get the results for in total 22 findings.
  • The results will be put into the directory result/ and processed/.
  • The number of findings mentioned in the paper will be printed by the R scripts.
  • If you want to get the results for individual findings, go to scripts/ and run the corresponding scripts.
