Cinder is a block storage service for OpenStack™ platforms that is designed to present storage resources to end users for consumption by the OpenStack Nova Compute Project. KumoScale™ storage resources are provisioned to OpenStack platforms through a Cinder driver plug-in and a connector to Nova compute.
KumoScale software currently supports OpenStack version Wallaby. KumoScale software can be integrated with other OpenStack versions by applying a patch. The KumoScale Cinder driver has been contributed to the OpenStack community and works with Linux™ operating system kernel versions that fulfill the following requirements:
- Support for the NVMe-oF™ protocol
- Deployed with client-side mdraid[1] (MD)
This document describes the configuration steps required to integrate KumoScale software into an existing OpenStack deployment and how to provision KumoScale volumes to an OpenStack environment.
Setup
The following illustration (Figure 1) depicts how KumoScale software integrates to an OpenStack environment:
