One of the common needs of a cloud platform is to scale resources as compute and storage needs expand. Over time there is often a need to add additional compute resources, as the required VM (Virtual Machine) growth has exceeded planned capacity. Likewise, storage resources must expand to keep up with demand. Compute nodes are used for hosting VMs, and storage nodes are used for hosting Red Hat Ceph Storage version 1.3.2, which manages block, image, and ephemeral storage, in the Dell Red Hat OpenStack Cloud Solution.
This technical guide explains the process of adding a Dell PowerEdge R730/R630/R430 compute node or R730XD storage node to an existing cluster in the Dell Red Hat OpenStack Cloud Solution Version 5.0.
