Open Source Development. Reimagined.

"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." 

“Klara a travaillé sur certains de nos sujets liés à FreeBSD. 

Leur expertise dans ce domaine nous a permis de faire avancer nos projets de manière efficace et au niveau de qualité attendu. 

La communication avec Klara est très bonne et efficace. Ils sont toujours disponibles pour répondre à nos questions et pour traiter de nouveaux sujets en collaboration. 

Lorsqu'un sujet est lancé, nous avons une très bonne visibilité sur leur progression. Le résultat est toujours à la hauteur de nos attentes et nous sommes ravis de cette collaboration."

“Klara handled some of our development topics related to FreeBSD. Their expertise on this subject allowed us to move our projects forward while maintaining the expected quality level.

Our communications with Klara are very good and efficient. They are always available to answer our questions and to deal with new topics in collaboration.

When a project is launched, we have very good visibility on their progress. The result is always up to our expectations, and we are delighted with this collaboration.”

“Klara handled our entire FreeBSD kernel development project. Their emphasis on communication was great. When we encountered issues, they quickly stepped in and created workable solutions.”

"Working with Klara has been exceptional. We had a hardware configuration issue that caused all ZFS member disks in our 300TB array to become unrecognized after a reboot. When our systems administrators reached their experience limit, Klara's team responded very quickly, recovering the research data in 1.5hr. 

The depth of Klara’s experience and customer base truly shine through in their ability to resolve even the quirkiest of issues. While one might hope to never need them, we’re glad we did. We now have a monthly support subscription to always have the expertise of Klara available.”

"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."

"We enlisted Klara to help us recover data on a web server that appeared to have a corrupt ZFS pool. While the root cause remains undetermined (faulty drives are suspected), the Klara team was able to recover the data and save our client days, if not weeks, of redevelopment. Communication from the team was good, and they explained what they were doing every step of the way. We won’t hesitate to work with them again in the future."

“We were struggling with stability issues on our FreeBSD Samba server after some changes to our workload. Klara was able to diagnose the issue, explain the underlying cause, and apply changes to resolve not only the stated issue but addressed a few additional concerns with our system. Their solutions gave us not only the resolution to the problem, but the knowledge to better maintain our own systems for the future.”

“The developers at Klara Inc. have been outstanding in helping Wasabi resolve ZFS issues and improve performance. Their understanding of ZFS internals is unmatched anywhere in the industry."
