Openshift Storage: Don’t Settle for Less Than SDS

Jul 01st, 2025 | 6 min read

Running scalable, high-performance workloads on OpenShift takes more than container orchestration. You need a storage layer that keeps up. That’s where software-defined storage (SDS) comes in.

As applications grow, so do demands on storage, especially for databases, machine learning pipelines, and stateful services. Traditional storage systems like NFS and Ceph can get you part of the way, but they weren’t built for the flexibility and speed modern OpenShift environments demand.

Learn why SDS is essential for OpenShift, where older systems fall short, and how Simplyblock delivers a faster, smarter storage solution built for today’s workloads.

Why Software-Defined Storage Is Critical for OpenShift

OpenShift makes it easy to build and scale containerized applications. But containers, by nature, are stateless. That means they need persistent storage that can scale, migrate, and adapt to the changing workloads.

Here’s where SDS becomes a must-have:

  • Flexibility – SDS runs on any infrastructure: cloud, bare metal, or hybrid
  • Scalability – Scale storage on demand without rebuilding or reconfiguring apps
  • Performance – Get consistent throughput and low latency, even as clusters grow
  • Automation – Let Kubernetes handle provisioning and scaling without manual work

Examining real-world scenarios, such as database performance optimization, it becomes clear that a rigid storage approach can quickly reach its limits when workloads grow or shift unexpectedly.

Key Benefits of Using Software-Defined Storage with OpenShift

Choosing the right storage isn’t just about capacity—it’s about how well it supports the way OpenShift runs. Here’s what you gain with a modern SDS solution like Simplyblock:

  • Faster Application Performance
  • Elastic Scaling
  • Always On
  • Infrastructure Agility
  • Lower Operational Overhead

Whether you’re supporting mission-critical apps or looking to optimize Kubernetes storage costs, a modern storage layer makes a measurable difference.

Core Features That Matter in OpenShift Storage

If you’re building on OpenShift, your storage solution needs to meet Kubernetes-native standards while delivering enterprise-grade performance. Simplyblock checks all the boxes:

  • Native CSI Integration
  • NVMe/TCP Support
  • Dynamic Provisioning
  • Multi-Zone High Availability
  • Built-in Monitoring
  • Storage Class Flexibility

Also worth noting: Simplyblock supports OpenShift deployments as well as hybrid and multi-cloud environments.

Use Cases: When OpenShift Needs High-Performance Storage

Wondering where SDS like Simplyblock makes a real impact in OpenShift environments? Here are a few practical examples:

  1. Databases and Stateful Services
    From PostgreSQL to MongoDB, these workloads demand speed and persistence.
  2. AI/ML and Data Pipelines
    Keep inference and training jobs fast with NVMe-backed storage.
  3. CI/CD Infrastructure
    Handle build logs, caches, and volume churn without bottlenecks.
  4. Edge Deployments
    Run OpenShift consistently in remote or air-gapped environments.
  5. Hybrid or Multi-Cloud Workloads
    With multi-cloud support, you can deploy OpenShift across regions or providers without re-architecting storage.

Choosing the Right Storage for OpenShift Isn’t Optional

When OpenShift workloads scale, storage becomes a pressure point. Whether you’re running databases, CI/CD pipelines, or AI workloads, your storage system needs to be fast, resilient, and built to match Kubernetes-native patterns.

Legacy tools like Ceph and NFS are still widely used, but they weren’t designed for today’s hybrid, high-performance cloud environments. And as clusters grow, the limitations become more obvious: added latency, manual configuration, and scaling challenges.

That’s where Simplyblock comes in. It removes the operational complexity and gives OpenShift the performance headroom it needs, without the baggage of legacy infrastructure.

Here’s a quick breakdown of how Simplyblock stacks up against traditional options:

Why Simplyblock Works Better with OpenShift

Simplyblock is built for modern infrastructure. It’s lightweight, fast, and specifically designed for cloud-native platforms like OpenShift. Instead of bolting on legacy storage, Simplyblock brings a fresh architecture that fits how OpenShift operates today.

Here’s what makes it stand out:

NVMe over TCP (NVMe/TCP)

Simplyblock uses NVMe/TCP—a protocol that delivers local-disk performance over Ethernet:

  • Blazing fast IOPS and low latency
  • No specialized hardware required
  • Works across standard infrastructure setups

Native CSI Support

With full Container Storage Interface (CSI) integration, Simplyblock works seamlessly with Kubernetes and OpenShift.

  • Dynamic provisioning
  • Snapshots and cloning
  • Volume lifecycle automation

It aligns natively with OpenShift Storage features, including persistent volume claims and storage class automation.

Built for Cloud-Native Workloads

Where Ceph and NFS fall short, Simplyblock supports:

  • Stateful containers
  • Cloud-native databases like PostgreSQL and MongoDB
  • CI/CD pipelines
  • AI/ML and analytics platforms

For organizations invested in OpenShift, Simplyblock provides a modern storage layer that keeps pace with the platform’s flexibility and scale.

Making the Right Storage Choice for OpenShift

Storage can be the bottleneck—or the advantage—in your OpenShift setup. While Ceph and NFS are still widely used, they weren’t built for the demands of modern, cloud-native environments.

Software-defined storage gives OpenShift the flexibility, scalability, and speed it needs to grow. And Simplyblock takes that a step further, combining the performance of NVMe/TCP with seamless Kubernetes integration through CSI.

If you’re serious about scaling OpenShift with less effort and better performance, it’s time to rethink your storage layer.

Questions and answers

Why is persistent storage critical for OpenShift workloads?

 Persistent storage is essential for running stateful applications like databases, analytics, and backups in OpenShift. It ensures data survives container restarts or rescheduling. Platforms like Simplyblock provide Kubernetes-native storage optimized for performance, scalability, and data resilience across clusters.

What is CSI (Container Storage Interface) in OpenShift?

 CSI is a standardized API that enables Kubernetes and OpenShift to dynamically provision and manage external storage like block or file volumes. Simplyblock’s CSI driver offers advanced features such as snapshots, cloning, and multi-tenant isolation. Learn more in our CSI glossary.

What is block storage, and why is it used in OpenShift?

Block storage provides fast, low-latency access to raw volumes, ideal for databases, container workloads, and VM disks. With Simplyblock’s NVMe-over-TCP integration, OpenShift users benefit from superior I/O performance and simplified volume management.

How does NVMe-over-TCP improve OpenShift storage performance?

NVMe-over-TCP enables ultra-fast storage access over standard Ethernet without special hardware. This protocol slashes latency and boosts IOPS, outperforming legacy solutions like iSCSI and making it perfect for modern workloads in OpenShift.
