vSAN Hardware Compatibility List Checker

The vSAN Hardware Compatibility List Checker is a tool that verifies all installed storage adapters against the vSAN supported storage controller list. The tool will verify if the model, driver and firmware version of the storage adapter are supported.

Using a supported storage controller and firmware is important in a vSAN deployment to ensure normal operations, optimal performance, and to reduce the chances of hardware/firmware issues. This tool can be useful to ensure that a storage device and its firmware went through certification testing supported by VMware and its partners.

Some scenarios where the tool can be useful:

  • Verify if new server and storage adapter are supported for a vSAN deployment
  • Verify if re-purposed server, storage adapter are supported for a vSAN deployment

For a full vSAN system check, please check vSAN health UI through vSphere web client after a vSAN deployment.
