Why ZFS for Independent Storage

OpenZFS allows storage systems to be structured deliberately from the start.

It integrates data integrity, snapshots, and replication within a single architecture that runs on industry-standard hardware. This allows teams to define failure domains, scale capacity incrementally, and replace hardware without redesigning the storage layout.

For organizations that expect their storage systems to grow and change over time, that clarity reduces operational risk.

Trusted by Engineering Teams Across Europe

"Cooperation with Klara has saved us considerable time and helped us pass security qualifications—ultimately resulting in an even better OPNsense firewall. We always appreciated the professional attitude of the people at Klara and their in-depth knowledge of various parts of the kernel."
— Ad Schellevis,CIO,Deciso B.V.

"At Plantformance, we leverage ZFS extensively in our products, pushing it to its limits. When we encountered a critical, undocumented memory consumption issue for which there was no available solution, we turned to Klara Systems.
Their team responded immediately with a clear proposal. They were able to rapidly diagnose the problem and engineer a custom patch for our software stack.
We were impressed not only by the speed and efficiency of their work but also by the fact that their solution was robust enough to be subsequently upstreamed into the OpenZFS project for the benefit of the entire community. The collaboration was seamless and incredibly effective. We highly recommend Klara Systems for any complex ZFS or open-ZFS software challenges."

Our Services

Why Klara

Klara combines upstream OpenZFS expertise with practical production experience. We support organizations that require clear architecture, predictable performance, and direct access to engineers who understand the storage stack in depth.

  • Reduced Time Spent Troubleshooting
    Instead of relying on community forums, teams work directly with engineers experienced in OpenZFS architecture, performance analysis, and production debugging.
  • Scalable Storage Architecture
    We design and refine OpenZFS environments so expansion, migration, and hardware refresh can be planned and executed in controlled stages.
  • Operational Stability
    Our support includes troubleshooting, upgrades, and structured change management to reduce disruption in live environments.
  • Integration with Existing Infrastructure
    OpenZFS deployments are aligned with your current compute, networking, and operational tooling rather than introduced as isolated systems.
