Red Hat OpenShift virtualization
The Red Hat® OpenShift® provides a platform for running virtual machines and container workloads side by side. It relieves you of maintaining separate infrastructure, platforms, tools, skills, and teams for virtual machines and containers. It also enables virtual machines to be managed with the same modern practices that are used for containers.
IBM Fusion provides high-performance infrastructure, storage, encryption at rest, and resiliency to run virtual machines on Red Hat OpenShift.
The RWX (ReadWriteMany) mode is crucial because it enables Live Migration for virtual machines in Red Hat OpenShift. With RWX block storage support, virtual machines can seamlessly move between nodes within the OpenShift cluster during Live Migration while maintaining the performance benefits of the block storage.
IBM Fusion HCI System provides the infrastructure to run Red Hat OpenShift on Bare Metal- x86 compute workers, a high-speed network, and storage. The appliance is designed with redundancy in mind, allowing for servers, switches, and drives to fail without impacting virtual machines that run in the cluster. IBM Fusion HCI System uses an IPI installation of Red Hat OpenShift, which enables the cluster to run without an external load balancer.
Virtual machine resiliency can be provided in the following ways:
- High availability is achieved by using three-way replication to mirror data across availability zones. It allows workloads to continue to run even when storage infrastructure fails.
- RWX storage enables Live Migration, which allows virtual machines to be moved between nodes in the cluster.
- Backup capabilities protect virtual machines from data loss or corruption, enabling them to be restored to an earlier point in time. You can restore the virtual machines to an alternative cluster to recover from a complete cluster failure or practice recovery.
