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.
