Red Hat Ceph Storage Other Advice

Sr. Systems Engineer at a tech company with 10,001+ employees
Ceph is open source and there are large organizations running huge Ceph clusters which have published blogs on how they deployed Ceph. Do your research based on the lessons learned from these users of Ceph to decide on which configuration and architecture to use for Ceph. As organizations move to Linux container based technologies and container orchestration frameworks (especially Kubernetes), Ceph is still relevant as it provides integration into these future technologies to provide block storage for them as well. It's ultimately all about IOPS. When a failure occurs CEPH tries to 'rebalance' data on the surviving nodes which can consume a lot of IOPS affecting client IO. If there's not enough IOPS or fast data rebalancing, it can take a lot of time to rebalance data. Some of this can be improved with faster networks and faster drives like SSD or flash drives (which people can implement right now in older versions of CEPH), some of the improvements will come from how CEPH writes data using BlueStore and replicate or rebalance data between OSD nodes using RDMA (which may become stable for users in newer versions).

I have been using Ceph since 2015, in both SOHO and bigger private cloud installations. Ceph, as a distributed storage solution, is amazing and I can only rate it a 10 out of 10. However, being distributed and complex, Ceph needs engineers with a good understanding of its internals and Linux, for it to shine. Overall, it is a great product. View full review »
