Release Date: August 22, 2016



HCIBench stands for "Hyper-converged Infrastructure Benchmark". It's essentially an automation wrapper around the popular and proven open source benchmark tools: Vdbench and Fio that make it easier to automate testing across a HCI cluster. HCIBench aims to simplify and accelerate customer POC performance testing in a consistent and controlled way. The tool fully automates the end-to-end process of deploying test VMs, coordinating workload runs, aggregating test results, performance analysis and collecting necessary data for troubleshooting purposes.

HCIBench is not only a benchmark tool designed for vSAN, but also could be used to evaluate the performance of all kinds of Hyper-Converged Infrastructure Storage in vSphere environment.

  • Web Browser:
    IE8+, Firefox or Chrome
  • vSphere 5.5 and later environments for both HCIBench and its client VMs deployment
See the HCIBench_2.5_User_Guide.pdf for details.
