Why Clyso

Ceph Experts You Can Trust.

We work on Ceph upstream every day, so the answer to your problem is often already in our heads, or in the code we wrote.

Helping Lead Ceph

One of the three co-chairs of the Ceph Executive Council, two Ceph Steering Committee members, and four Ceph Ambassadors are from Clyso.

Proven Since 2010

350+ projects since 2010, from SAP to Fortune 500 companies, government, and NGOs.

Rapid Response

Two-hour response to severity-1 issues, around the clock if you need it, and emergency help even without a contract.

The Whole Lifecycle

Architecture, hardware design, deployment, upgrades, tuning, recovery, and Ceph on Kubernetes: our engineers contribute to Rook.

Recently merged into Ceph by Clyso engineers

After a failed Ceph upgrade on our cluster with approximately 10 petabytes of data, we needed external support. Clyso helped us to get the cluster back online in no time.

With SAP

Ceph on Kubernetes at Petabyte Scale

SAP and Clyso engineers run SAP's Ceph fleet with Rook, from bare-metal provisioning to rolling upgrades, and wrote up how in a joint whitepaper.

Emergency support

Cluster Down? We Help, Contract or Not.

Data unavailable, an upgrade gone wrong, OSDs that will not come back: our engineers have been recovering Ceph clusters for over a decade, and they start at the source of the problem.

  • Open to everyone. You do not need a support contract with us. National laboratories, storage vendors, and hosting providers have called us in.
  • Paid per incident. A flat fee covers the first four hours of troubleshooting, then hourly, and is credited toward a support subscription signed within 30 days. We start once you approve the terms in writing.
  • Already a customer? Use your support channel: your tier's response time applies.

1 TiB/s From a single Ceph cluster, believed to be the first to reach it: 68 NVMe nodes on Ceph Quincy, tuned by Clyso in January 2024, then moved into production with all data migrated in two weeks. Read How We Got There

Ceph for HPC and AI

Storage That Keeps Up With Your Compute.

Training data, checkpoints, scratch, and archives: one open platform, no vendor lock-in, and engineers who know where every microsecond goes.

  • Throughput at scale. Clusters tuned end to end, from NVMe and network to CephFS and RGW.
  • Data that survives. Failure domains, upgrades, and recovery planned before they matter.
  • Costs you can plan. Commodity hardware, sized for the workload, without license surprises.
