What's Inside

• zapraid_prototype, storing the prototype itself, implemented with C++
• zapraid_spdk, storing modified SPDK, with added SPDK bdev module for zapraid
• zapraid_femu, storing modified FEMU, with added ZNS SSD latency emulation functionality
• scripts, storing neccessary scripts for running all the experiments
• patches, storing our modifications to SPDK and FEMU

Building Guide

• Be sure to read this building guide before proceeding, and be sure to read every scripts before running it when doing experiments.

• ZapRAID SPDK

  • Build zapraid_spdk without zapraid first; configure with "--without-zapraid"
  • Build zapraid_prototype; specify the "SPDK_DIR" in src/CMakeLists.txt
  • Build zapraid_spdk again with zapraid; configure with "--with-zapraid=DIR"
  • Check scripts in scripts/ for running spdk fio and real applications

• ZapRAID FEMU

  • Follow the FEMU build guide
