HDD-Only Nodes

Table of Contents

Introduction

It is possible to create an HDD-only node. This means that this node doesn't have SSD disks, but only HDD disks.

The steps are almost all the same, except for the creation of the Zero-OS Bootstrap image, which needs an extra kernel argument.

The requirements and BIOS parameters differences are also covered.

Requirements

An HDD-only node needs at least 100GB of HDD disk.

BIOS Parameters

In the BIOS, make sure to set AHCI for SATA disks.

Bootstrap Image for HDD-Only Nodes

To create an HDD-only node, the bootstrap image needs an extra kernel argument:

  • Navigate to the Zero-OS Bootstrap site.
  • Select Expert mode from the menu at the top.
  • Fill in all the needed inputs (Farm ID, network, kernel and format).
    • You can keep the default kernel
  • In the Extra kernel arguments input field, type missing-ssd.
  • Generate and download the image.
