Introduction

You can perform StarlingX node management of worker hosts that comprise resource pools for hosting guest applications.

You can change the resource pool in several ways:

• You can add or remove hosts to increase or decrease the size of the pool.

• You can replace a host with another that has different resources; for example, memory, or number of CPU cores.

• You can adjust the resources on an existing host.

• You can replace a failed worker node host with an equivalent.

• You can add or remove standard and low-latency worker hosts to adjust the mix of performance profiles on a system.

Caution

When replacing or adjusting a host, ensure that the overall resource pool still meets the requirements for your system.

Complete instructions for adding a worker node are provided in the StarlingX Installation and Deployment Guide.
