CEPH – OPEN SOURCE SCALE-OUT STORAGE

In the following we would like to give you an insight into our training agenda. Please do not hesitate to contact us if you have any questions. We are also happy to include other topics or tailor the course to your individual needs. We can also offer in-house training.

Ceph is a high performance open source storage solution. Thanks to its massive and simple scalability, Ceph is suitable for almost all application scenarios. These include virtual servers, cloud, backup, and much more.

TRAINER

We pay special attention to direct practical relevance in all courses. Therefore all our trainers have extensive knowledge in dealing with Ceph, Linux, networks and software development. As developers of the innovative Ceph Storage Management Software, we can fall back on knowledge from a multitude of projects and thus offer the best possible range of services. We strongly believe that this is unique in the market.

MATERIALS PROVIDED

Digital documentation
Virtual training center

TARGET GROUP:

Our course is aimed at IT administrators who need to ensure 24/7 operation of the storage environment. Typically, they are in regular contact with developers, users or run their own storage applications. As previous knowledge we expect basic knowledge in Linux.
