Block storage remains the layer where stateful infrastructure either feels fast and controllable or slow and fragile.
Databases, virtual machines, and persistent application volumes all surface storage quality very quickly, which is why
modern platform teams still care deeply about block storage even when everything above it looks cloud-native.
This page is the commercial block-storage layer in the simplyblock cluster. If the target platform is already clear,
continue into Kubernetes Storage or
OpenShift Storage.
Where SAN and cloud-volume habits start to break
The older block-storage habit is to optimize one environment at a time and accept specialist operating overhead as the
cost of control. That model breaks down when one team has to support more clusters, more workloads, and more
shared-stateful infrastructure without multiplying storage silos.
That is the point where software-defined, NVMe-first block storage becomes more useful than another round of appliance
tuning or volume-by-volume workarounds.
From block volumes to databases, Kubernetes, and private cloud
Block storage gets more strategic when it becomes the shared layer under databases, Kubernetes operators, KubeVirt
workloads, and private-cloud services. That is why this page works best as the storage-foundation page in the wider
cluster, not as an isolated technology explainer.
If the architectural proof matters most, continue into NVMe over TCP Storage. If
the bigger platform story matters more, continue into Private Cloud Storage.
