Installing InfoScale on OpenShift
InfoScale provides robust, high-performance storage management for Red Hat OpenShift, supporting enterprise-grade reliability for containerized workloads and OpenShift Virtualization. The solution enables flexible deployment across standard, air-gapped, and specialized environments such as Two-Node Arbiter (TNA) and Two-Node Fencing (TNF) clusters. Key architectural features include Flexible Storage Sharing (FSS), support for both shared and hyperconverged storage models, and advanced data protection through encryption and optimized fencing strategies.
Deployment requires careful preparation of the OpenShift environment, including ensuring network synchronization via NTP, reserving specific ports for communication (LLT, VVR), and configuring kubelet graceful shutdown inhibitors to prevent resource conflicts. Administrators must ensure FQDN matching, install necessary dependencies like Cert Manager, and verify that stale kernel modules are purged. Installation is managed via Custom Resource (CR) YAML files, allowing for the configuration of multiple clusters, each capable of supporting up to 16 nodes.
For operational integrity, InfoScale leverages disk-based or CPS-based fencing to maintain high availability and data consistency. Integration with OpenShift Virtualization is fully supported, utilizing CSI StorageClasses and SnapshotClasses for enterprise-level virtual machine storage. The platform provides extensive flexibility in volume layout and performance tuning, ensuring consistent behavior across physical, virtual, and cloud-native storage layers.
