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.

Kubernetes is no longer just a container orchestrator. As organizations modernize infrastructure, there’s growing interest in using Kubernetes to manage virtual machines (VMs) alongside cloud-native workloads—while still meeting familiar expectations like disaster recovery (DR).
In this post, we’ll walk through a practical, GitOps-friendly DR approach for VMs running on Kubernetes using:
CAP_SYS_ADMIN Without Breaking StorageMany Kubernetes storage drivers still rely on the powerful—and notoriously over‑broad—Linux capability CAP_SYS_ADMIN to perform host‑level operations. While it enables critical actions like filesystem mounts, it also substantially expands the attack surface of your cluster.
This post explains why CSI node plugins often end up needing CAP_SYS_ADMIN, what breaks when you remove it, and several concrete hardening strategies using tools like seccomp, AppArmor, SELinux, and controlled privilege elevation.

The Dell CSM Kubernetes Operator packages the CSI driver and other storage services (Container Storage Modules) for observability, replication, authorization, and node resiliency. This single operator supports PowerFlex, PowerStore, PowerScale, and Unity platforms (see Support Matrix ). This post lays out best practices for deployment and lifecycle management of Dell CSMs.
With all the Dell Container Storage Interface (CSI) drivers and dependencies being open-source, anyone can tweak them to fit a specific use case. This post shows how to create a patched version of a Dell CSI Driver for PowerScale.

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.
To patch a Helm chart without modifying the template manually, you can combine Kustomize's patch transformer and Helm chart generator .

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.

With the 2023 addition of Kubernetes on LinuxOne, you can scale, reduce TCO, and build the hybrid cloud your IT management requires. Combined with Dell PowerMax storage and its CSI driver, you get container orchestration with enterprise storage on mainframe hardware.
delve with KubernetesSome time ago I faced a bug where it was untrivial to understand the precise workflow.
One of the beauties of the open-source is that the user can also take the pilot seat ;-)
In this article, we will see how to compile the Dell CSI driver for PowerFlex with a debugger, configure the driver to allow remote debugging, and attach an IDE.
