The Ceph distributed storage platform is a complex array of subsystems, and its overall performance is influenced by factors as diverse as local block storage IOPS and streaming writes, network throughput and latency, CPU utilization on servers and clients, Ceph configuration, and many other factors. When optimizing Ceph for performance, the many variables involved can make the task daunting. Fortunately, though, the intrepid storage administrator needs only a handful of tools to quickly establish performance metrics at all levels of the stack — and some of these tools are even built right into Ceph.

This presentation covers important Ceph performance metrics and tools, provides a walkthrough of bottom-up Ceph benchmarking, and provides guidance on how to properly interpret results and tune for performance optimization.
