Migrating vSphere VMs to SUSE Virtualization: The Storage Mapping You Declare Up Front
Every VM migration onto Harvester now starts with a storage mapping, declared once, before the first disk moves. That single form decides whether live migration works, whether multi-disk snapshots are usable, and whether you can change your mind later. Here is what belongs in it, and why landing on the bundled default is a decision you pay for twice.

Storage Tiering After the vSAN Exit: What Decides Which Data Sits on Flash
vSAN made the hot-versus-cold decision for you, at the disk group, with a ratio you fixed at build time. Leaving takes that decision away and hands nobody a replacement. Storage policies do not fill the gap, because they declare capability rather than placement. Here is who actually decides what lives on flash afterwards, and why the return trip out of cold storage is the part that turns into an incident.

K3s vs K8s vs RKE2 vs Talos: Compared by What Each Assumes About Storage
Every Kubernetes distribution comparison scores the same things: install time, footprint, upgrade model, air-gap story. None of them score the one default that decides whether the cluster can run production VMs, and it is set before you deploy a single workload. Here is what k3s, upstream Kubernetes, RKE2, and Talos each assume about storage out of the box, and what that assumption costs on Day 2.

Private Cloud Architecture After VMware: What the Storage Layer Has to Provide
Nine posts in this series answered the question what replaces this VMware feature. None answered the question underneath it: what are you actually building? The buyer's own word for it is private cloud, and most of the properties people miss when they leave vSphere turn out to be storage properties. Here are the six that matter, which ones your new platform gives you by default, and which ones the storage layer still has to supply.

Data Residency Requirements: The Sovereignty Decisions Your Storage Layer Makes
Sovereignty appears in the exit business case as a slide, then disappears into the architecture. It re-emerges as six storage decisions that nobody planned: where replicas land, where snapshots go, who holds the keys, who can reach the data plane, where telemetry is exported, and where the DR site sits. Most of them are made by a default rather than by a person. Here is the list, what vSphere decided for you before, and which defaults can cross a boundary without anyone noticing.

Migrating VMware to Red Hat OpenShift: The Storage Decisions MTV Makes For You
The Migration Toolkit for Virtualization asks you for one thing on the storage side: a StorageClass.

Here is what MTV actually does to your disks, which defaults hurt, and what the destination storage layer does and does not change.

What Replaces the VMware Datastore When You Leave vSphere
A datastore is a place you put virtual machines into. Its Kubernetes counterpart is not a place at all, it is a rule the cluster provisions from.

The Other VMware Exit: Storage for Providers Who Move Customers, Not Workloads

Leaving VMware Without a Hypervisor: Bare-Metal Kubernetes and the Storage Problem
Every VMware exit plan assumes the exit lands on another hypervisor. A third path exists: no hypervisor at all, containers straight on physical servers. It is a real option, and it removes something most teams do not notice they were relying on. Not the hypervisor, the datastore. Here is what bare-metal Kubernetes does to storage, why it strands capacity by default, and how the three exit paths actually compare.

VMware and Hyper-V Together: Storage for the Mixed Estate You Actually Have
Almost every VMware exit plan is written as if the source were a single vSphere cluster. Real estates are mixed: a vSphere cluster, an inherited Hyper-V failover cluster, cloud instances that started as a pilot, and a rack of physical servers nobody ever virtualized.

What Replaces VMware HA, DRS, and Fault Tolerance When You Leave vSphere
vSphere HA looks like a compute feature. It is not.
