InfoScale for Kubernetes with Red Hat OpenShift virtualization platform

InfoScale for Kubernetes is qualified for Red Hat OpenShift virtualization platform. It enables seamless integration of high-performance, resilient storage with virtual machine workloads. With this support, InfoScale for Kubernetescan be used to create CSI-based volumes in OpenShift that provide advanced data services such as high availability and dynamic provisioning. The storage-classes backed by InfoScale for Kubernetescan be used to provision virtual disks required by virtual machines in OpenShift virtualization. This ensures enterprise-grade storage reliability and performance for virtualized workloads.

Example of a storage profile which refers InfoScale storage class and snapshot class for creating virtual machines:

apiVersion: cdi.kubevirt.io/v1beta1 
kind: StorageProfile 
metadata: 
  name: csi-infoscale-sc   
spec: 
  claimPropertySets: 
    - accessModes: 
        - ReadWriteMany 
      volumeMode: Block 
  cloneStrategy: snapshot  
  snapshotClass: csi-infoscale-snapclass

Note:

cloneStrategy can either be a snapshot or a clone.

For creating a virtual machine using InfoScale provisioned storage, the user needs to mention appropriate storage class while selecting root disk and data disk.

Note:

Creating multiple VMs (100-200+) in a single batch is not recommended. We recommend to create a few VMs at a time and ensure that the VM state is running before creating a new set of VMs.

To create virtual machines

  1. Deploy a VIKE cluster. Create storage class ,snapshot class, and storage profile.
  2. Deploy OpenShift Virtualization operator.
  3. Navigate to Virtualization to create a new virtual machine
  4. Mention InfoScale storage class for boot disk and data disk
  5. Mention InfoScale storage class when adding the datadisk on a new or an existing VM.
