Leaving legacy virtualization?
Modernize stateful workloads on Kubernetes-native storage without dragging legacy architecture into your next platform.
Live webinar, Tue 24 Nov: How to replace vSAN at the edge. 16:00 CET (10:00 ET).
Leave VMware.
Keep your SAN.
Leave VMware without losing what storage did for you. One platform for block, shared file and S3 with disaster recovery built in. It runs on your existing SAN or on local NVMe drives, from the data center to the edge.
Run your VMs and databases on Red Hat® OpenShift® and Kubernetes on the storage you already have: your SAN, local NVMe drives, hyper-converged or not. One platform covers what vSAN, vMotion and Site Recovery Manager did, from the data center to the edge.
One storage platform for your VMware exit and everything after it.
Runs on your existing SAN or on local NVMe drives.
Disaster recovery built in, not licensed separately.
Block, shared file and S3 from one platform.

One platform
Start with the VMware exit. Keep the platform for everything after.
One storage layer and one operator cover block, disaster recovery, shared files, S3 and remote sites, on the storage you already have.
Run VMs and databases at NVMe speed
Low-latency block storage for VM disks and databases, with shared block volumes for VM live migration and erasure coding that needs about half the drives of three-way replication.
Recover from anything, restore fast
Metro replication with zero RPO, asynchronous replication with RPOs down to one minute, and backups to fast S3 on the same platform. No separate DR product.
Share files across nodes at block speed
A true shared filesystem (ReadWriteMany) through pNFS, with every client reading and writing directly over NVMe-oF. For AI training data, build caches and files shared between VMs.
Keep remote sites running
One- and two-node clusters for branches, stores and factories. Data stays on site, a node failure is survived, and every site is managed from one central control plane.
Runs on what you have
Keep your SAN. Keep your servers. Change what they can do.
Simplyblock sits between your workloads and your storage. Give it the LUNs of your existing SAN or the drives in your servers, and Kubernetes gets the same volumes, snapshots, QoS and disaster recovery either way. You keep the investment and move on your own schedule.

Provisioning, snapshots, expansion, and policy are reconciled by the operator, not ticketed. Declare a tier once; the control plane enforces it across restarts and upgrades.
- CRDs for every object — StorageNode, StoragePool, QoSProfile, and SnapshotPolicy, with drift detection and self-healing reconcile loops.
- Standard CSI — dynamic provisioning, expansion, snapshots, and clones through StorageClass, PVC, and VolumeSnapshot. No custom workflows for app teams.
- Scheduled policy — snapshots, retention windows, and cross-cluster replication, declared once and enforced by the control plane.
- CLI and API parity — everything the UI can do, scriptable for runbooks, rebalances, and bulk migrations.

One storage layer for OpenShift, Kubernetes, and stateful workloads.
Modern apps need fast, reliable, and scalable storage. Especially in Kubernetes or OpenShift. Storage bottlenecks slow teams down and distract from building great products. Simplyblock removes that complexity.
Our high-performance storage for Kubernetes combines NVMe over TCP (or NVME over RDMA), software-defined architecture, and SPDK acceleration to deliver blazing-fast I/O for databases, real-time services, and analytics. And because it's fully software-defined, there’s no vendor lock-in, giving you the freedom to choose and adapt your hardware as your needs evolve.
Simplyblock™ automates performance tuning, ensures tenant isolation, and delivers consistent QoS — so your teams can focus on innovation, not infrastructure.

Simplyblock
Control Center
Simplyblock can be fully managed via our CLI, our API, and the Control Center UI.
Control Center is a fully-featured user interface, enabling management, provisioning, and monitoring and ensures correct user permissions with an RBAC permission system.
Your Next Generation
Software-Defined Storage
High-performance storage without the hardware headaches. Deliver NVMe-level latency and throughput across your Kubernetes or OpenShift clusters using standard TCP networking (also supporting RoCEv2 with NVMe/RDMA). No custom drivers, no lock-in. It’s storage performance reimagined for the cloud-native world. 
Seamless integration, zero friction. Simplyblock was built from the ground up for Kubernetes or OpenShift. From CSI compatibility to automated scaling and provisioning, it fits into your DevOps workflows — not the other way around.
Blazing speed, smart orchestration. Powered by SPDK, Simplyblock removes software bottlenecks and automates tiering, QoS, and IOPS balancing. You get consistent, ultra-low latency without manual tuning. As the only SDS solution supporting NVMe/RDMA, you can achieve even more consistent tail latency.
Run on any hardware, scale independently, and avoid lock-in. Hyper-converged or disaggregated. Simplyblock is fully software-defined. Run it in the cloud or on-prem with full control over cost, performance, and footprint.
Built-in data durability and smart placement without manual tuning. Supporting various n+1 and n+2 erasure coding schemes for better efficiency. Turn up to 80% of your raw storage into usable capacity. Unparalleled efficiency compared to other solutions on the market.

Here are the key reasons why simplyblock is the data platform of your choice.
✅ Smarter Storage for Data-Intensive Workflows
Simplyblock intelligently handles high-throughput workloads by dynamically balancing performance, latency, and cost. From OLTP databases to event streaming and analytics pipelines, your data is always where it needs to be — no manual tuning required.
🚀 Performance That Grows With You
Simplyblock's storage engine is highly optimized for NVMe flash storage for Kubernetes. It provides logical volumes using the low overhead NVMe over TCP (or NVME over RoCE) protocol and combines NVMe devices into a cluster-wide storage pool. Multipathing via NVMe over TCP enables parallelized access, minimizing access latency for small and large files, making NVMe and Kubernetes a powerful combination for performance-driven workloads.

Edge Modernization for Stores and Warehouses: Designing the Two-Server Site
An edge fleet is one small site design repeated many times. Decide what must stay on site, whether a site gets one server or two, and how two servers stay available without a storage witness at the site, before you pick the pilot sites.

A Complete Storage Package for OpenShift Virtualization: What to Ask For
VM disks, recovery, shared files, and object storage are often bought as four products. On OpenShift they can come from one storage platform, and the limits of that answer are worth knowing before you ask for it.

Your Storage Works in the Lab. What to Test Before VMs Run in Production
A lab shows that storage installs and a VM boots. Before production, test a node drain, a node failure with its rebuild, performance under real load, and a full recovery, each against a limit you set in advance.

PostgreSQL on Kubernetes: Do's and Don'ts
Running databases in containers has long been considered an anti-pattern. However, the Kubernetes ecosystem has evolved significantly, allowing stateful workloads, including databases, to thrive in containerized environments. With PostgreSQL continuing its rise as one of the world’s most beloved databases, it’s essential to understand the right way to run it on Kubernetes. This session will cover the key Do’s and Don’ts to ensure optimal performance and scalability.
