## 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](https://bootstrap.grid.tf/).
|
||
|
|
- 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.
