CSI for PowerFlex on OpenShift with Multiple Networks

Managing multiple networks for storage workloads on OpenShift is not optional: it is essential for performance and isolation. Dell PowerFlex , with its CSI driver, delivers dynamic storage provisioning, but multi-network setups require proper configuration.

This guide explains how to enable multi-network support for CSI PowerFlex on OpenShift, including prerequisites, network attachment definitions, and best practices for high availability.

Enable Storage Multi-tenancy on Kubernetes with PowerScale

Dell PowerScale is a scale-out NAS solution designed for high-performance, enterprise-grade file storage and multi-tenant environments. In multi-tenant environments, such as shared Kubernetes clusters, isolating workloads and data access is critical.

PowerScale addresses this need through Access Zones, which logically partition the cluster to enforce authentication boundaries, export rules, and quota policies. The Dell CSI driver maps Kubernetes StorageClass resources to specific Access Zones, providing per-tenant isolation at the storage layer.

This setup is particularly useful when multiple teams share a common PowerScale backend but require strict separation of data and access controls. This approach proved extremely valuable when building a GPU-as-a-Service AI Factory .

Use Harvester with Dell Storage

Co-authored with Parasar Kodati.

Dell CSI drivers for PowerStore, PowerMax, PowerFlex, and PowerScale have all been tested and are compatible with KubeVirt . This guide provides instructions for installing Dell CSI for PowerMax on Harvester , though the steps are very similar regardless of the storage backend.

Tested on :

  • Harvester v1.3.1
  • CSM v2.11
  • PowerMax protocols : Fibre Channel, iSCSI, and NFS

Network Design for PowerScale CSI

Co-authored with Sean Zhan.

Network connectivity is an essential part of any infrastructure architecture. When it comes to how Kubernetes connects to PowerScale, there are several options to configure the Container Storage Interface (CSI). This post covers the concepts and configuration you can implement.

Kubernetes Node Non-Graceful Shutdown and Remediation: Insights from Dell Technologies

Co-authored with Michael Wells Jr.

Kubernetes has become a pivotal technology in managing containerized applications, but it is not without challenges, particularly when dealing with stateful apps and non-graceful shutdown scenarios. This article explores how to handle such situations and, more importantly, how to enable automated remediation.
