Deploying Storage Nodes


KumoScaleTM Storage Nodes provide storage volumes to clients. In a data center, Storage Node deployment or decommissioning is a continuous process. KumoScale Storage Nodes are deployed in three steps:

  • Install KumoScale OS onto the target/Storage Node (a customized version of CentOS® software)
  • Configure the KumoScale Storage Node
  • Update Management Services with the KumoScale Storage Node state

Installation of Storage Node

KumoScale Storage Nodes use the KumoScale OS which runs on a compatible server. Refer to the hardware compatibility list (HCL) for a list of supported servers. A typical large environment stores OS images in a central location, usually a TFTP and/or http server.  Servers are installed with the KumoScale OS image via PXE boot. 

The KumoScale software distribution includes a PXE install OS image which can be stored along with other OS images in the data center.  Deployment involves PXE booting a new server from the KumoScale PXE boot image. The KumoScale OS image (golden image) provides a fully automated process for deploying a new Storage Node. Please refer to documentation for additional details.

Configuration of Storage Node via Management Cluster

Once a KumoScale Storage Node is installed, Management Services must be made aware of its existence. This is two-step process and can be done easily via provided automation scripts (Ansible® or REST Commands). A new Storage Node is initialized and then added as a back end to the KumoScale provisioner service running in the Management Services cluster.
