Persistent Storage for Kubernetes

Powering Stateful Workloads with Simplyblock's Software-Defined Storage

Kubernetes has transformed the way organizations build and scale modern applications. But persistent storage remains one of its biggest challenges — especially when stateful workloads demand speed, scalability, and simplicity.

Simplyblock is designed from the ground up for Kubernetes, Simplyblock provides high-performance, software-defined block storage that turns your cluster into a true foundation for enterprise-grade, stateful applications.

Built for Kubernetes from Day One

Smoothly Scalable

Persistent volumes that scale with your workloads

Seamlessly Integrated

Snapshots, clones, and volume expansion via native Kubernetes APIs

Fully Automated

Instant provisioning and deprovisioning the Kubernetes-way

The True Kubernetes Storage

Why Simplyblock Is the Storage Platform Kubernetes Deserves

Simplyblock is unified, adaptive, fast. Just like Kubernetes itself.

At the core of simplyblock lies our MAUS Architecture — Modular, Adaptive, Unified, Shared-Everything.
It’s the reason we outperform legacy solutions and traditional SDS platforms.

With simplyblock, it doesn't matter where you operate your Kubernetes, because it brings hyperscaler-level storage capabilities to your Kubernetes cluster. Whether on bare metal or virtualized environments, Simplyblock’s Proxmox VE integration brings Kubernetes clusters hyperscaler-grade storage flexibility.

Unified Storage Pool

Abstracts NVMe, SSD, HDD, and object storage behind a single, logical NVMe interface.

Flexible Deployment Model

Deploys hyper-converged, disaggregated, or in a hybrid model, offering the best performance for your workloads.

Near-Local Performance

Uses NVMe over Fabrics to ensure ultra-low latency—even for remote volumes.

Seamless Integration

Integrates with its own CSI driver for seamless workflows in a Kubernetes-native fashion.

Day-2 Operations: All Batteries Included

For platform engineers and DevOps teams, simplyblock makes daily operations easier:

Multi-Tenant and QoS

Multi-tenant support with isolated storage per namespace or project

Kubernetes-Native

Dynamic provisioning and resizing of volumes via Kubernetes

Always-On Storage Cluster

No downtime for cluster upgrades, extensions, or expansions

Self-Optimizing

Self-balancing storage engine for optimal performance

Persistent storage is where platform promises become real

Kubernetes only feels production-ready when persistent storage behaves the way platform teams need it to behave. That means snapshots, cloning, performance isolation, and predictable operations for stateful workloads. It also means storage has to fit both generic Kubernetes platforms and more opinionated environments like OpenShift.

Questions and Answers

How does simplyblock compare to Traditional SDS for Kubernetes storage?

Simplyblock is designed for predictable low-latency block storage, linear scaling, and simpler operations for Kubernetes workloads compared to traditional alternatives.

What changes are required to migrate from Traditional SDS to simplyblock?

Most teams migrate in phases: validate workload behavior, move stateful services gradually, and optimize policies for performance, resilience, and cost.

When is simplyblock a better fit than Traditional SDS?

Simplyblock is typically a strong fit when teams need modern Kubernetes-native storage, better performance efficiency, and easier day-2 operations at scale.
