Kubernetes Storage for Stateful Workloads

High-performance, CSI-native persistent storage for modern Kubernetes platforms

simplyblock gives Kubernetes teams an NVMe/TCP block-storage layer built for databases, analytics services, AI pipelines, and other stateful workloads that cannot tolerate storage drag. Use familiar CSI-based workflows, snapshots, and cloning while staying flexible across hyper-converged, disaggregated, or hybrid deployment models. If your platform direction later becomes Red Hat or private cloud, the storage path does not need to reset.

simplyblock supports Kubernetes storage programs that need a practical path into OpenShift, software-defined storage, and private cloud without changing the underlying storage direction.

Where It Fits

Where simplyblock Fits Best in Kubernetes Platforms

Kubernetes storage becomes a platform issue when performance, stateful workloads, and long-term operating shape all need to line up. That is where simplyblock is strongest.

Stateful Workloads and Data Services

Support PostgreSQL, analytics services, message brokers, and other latency-sensitive applications that need more than default persistent volumes.

Platform Engineering and CSI Operations

Keep provisioning, snapshots, cloning, and persistent-volume management aligned with the way Kubernetes platform teams already operate clusters.

OpenShift and Private-Cloud Path

Use the broader Kubernetes page as the starting point, then move into OpenShift or private cloud storage when the platform standard becomes more specific.

Deployment Models

Choose the Kubernetes Storage Shape That Matches the Platform

Platform teams rarely want one fixed operating model forever. simplyblock supports the deployment shape that fits now and the architecture changes that come later.

Hyper-Converged

Keep compute and storage close when operational simplicity, fast rollout, and a smaller initial footprint matter most.

Disaggregated

Separate compute from storage when cluster growth is uneven or platform teams need more independent scaling and performance control.

Hybrid

Run both patterns where workload mix, cluster roles, or team boundaries demand more than one storage shape.

Core Capabilities

What simplyblock Brings to Kubernetes Storage

The strongest Kubernetes storage fit is not just about raw speed. It is about performance, CSI operations, and architectural flexibility working together.

CSI-Native Persistent-Storage Operations

Manage block storage through Kubernetes-native workflows instead of handling storage as an external silo.

  • Dynamic provisioning through StorageClasses
  • Snapshot and clone workflows for faster environment handling
  • Better fit for day-2 Kubernetes platform operations

Low-Latency NVMe/TCP Data Path

Use NVMe/TCP over standard Ethernet for low-latency block storage that supports demanding databases and stateful application patterns.

  • High-throughput data path without proprietary fabrics
  • Better latency profile for storage-sensitive workloads
  • Practical performance story for modern Kubernetes clusters

Snapshot, Clone, and Recovery Workflows

Keep environment creation, rollback, backup, and restore closer to the storage layer so platform teams can move faster with less manual effort.

  • Faster rollback and recovery motions
  • Cloning for test and staging environments
  • Better support for resilient stateful operations

One Direction Across Platform Evolution

Start on upstream Kubernetes, then extend toward OpenShift, private cloud, or broader software-defined storage goals without rethinking the core storage layer.

  • Support Kubernetes today and OpenShift later
  • Keep platform architecture flexible over time
  • Reduce storage rework during platform transitions

For platform and storage leaders

What the Storage Decision Changes for the Kubernetes Platform

Kubernetes storage sets the ceiling for stateful workload performance, the quality of day-2 platform operations, and how easily the platform can evolve into OpenShift, virtualization-adjacent workloads, or private cloud.

  • Standardize storage operations early

    Give platform engineering teams one consistent path for provisioning, snapshots, and cloning instead of a patchwork of volume behaviors.

  • Keep the OpenShift option open

    Avoid selecting a Kubernetes storage stack that becomes friction when the platform later standardizes on Red Hat.

  • Protect stateful workload performance

    Match the storage layer to the actual latency and throughput needs of databases, analytics services, and AI-adjacent pipelines.

  • Reduce future migration overhead

    Choose a storage direction that can move with the platform rather than forcing a redesign every time the infrastructure model changes.

Outcomes

The Key Benefits of simplyblock for Kubernetes Persistent Storage

These are the operational gains Kubernetes teams care about when persistent storage needs to scale with the platform instead of slowing it down.

Seamless Integration

simplyblock integrates with Kubernetes through CSI, enabling dynamic provisioning and persistent-volume management without disrupting existing platform workflows.

Deployment Flexibility & Scalability

simplyblock offers the broadest deployment flexibility of the industry. With hyper-converged, disaggregated, and hybrid setups, simplyblock optimizes for demanding Kubernetes workloads without locking the platform into one operating shape.

Enhanced Performance

Using NVMe/TCP, simplyblock delivers low-latency, high-throughput block storage for stateful applications like databases, analytics services, and performance-sensitive platform components.

Cost Efficiency

By implementing features like thin provisioning and intelligent data tiering, simplyblock optimizes storage utilization, reducing costs associated with overprovisioning and underutilization of resources.

Kubernetes storage as the broader foundation

This page owns the broader Kubernetes storage story. If your program is specifically Red Hat-aligned, the more specific next page is OpenShift Storage for Stateful Workloads. If you are replacing VMware and vSAN along the way, continue into VMware Migration to OpenShift and Kubernetes.

When Kubernetes storage becomes a platform decision

Kubernetes storage rarely stays a narrow infrastructure decision for long. Once platform teams need predictable performance for stateful workloads, consistent snapshot and cloning workflows, and a path into OpenShift or private cloud, storage becomes part of the wider platform architecture.

That is why simplyblock fits best when the storage question sits between day-2 Kubernetes operations and the longer-term platform direction.

Questions and Answers

What storage works best for Kubernetes stateful workloads?

Kubernetes stateful workloads usually need CSI-native block storage with predictable latency, snapshots, cloning, and straightforward day-2 operations. simplyblock is built for that pattern and supports databases, analytics services, and other storage-sensitive applications.

Is simplyblock only for OpenShift or does it also fit upstream Kubernetes?

simplyblock fits upstream Kubernetes as well as OpenShift-aligned environments. The Kubernetes page is the broader starting point, while OpenShift becomes the more specific path when Red Hat tooling and operating patterns are part of the platform standard.

Why do teams look at NVMe/TCP for Kubernetes storage?

NVMe/TCP gives teams a high-performance block-storage data path over standard Ethernet. That makes it attractive for Kubernetes environments that need low latency and high throughput without proprietary storage fabrics.

Can simplyblock support hyper-converged and disaggregated Kubernetes deployments?

Yes. simplyblock supports hyper-converged, disaggregated, and hybrid deployment models, which lets platform teams start with the shape that fits today and adapt architecture as workloads and economics change.

When should a Kubernetes storage evaluation move into OpenShift or private-cloud planning?

That shift usually happens when the storage decision becomes part of a broader platform standardization effort, a VMware-exit program, or a private-cloud plan. In those cases, the next step is often OpenShift storage or private cloud storage.
