Chapter 8. Production Planning and Performance Tuning for Ceph
In this chapter, we will cover the following recipes:
The dynamics of capacity, performance, and cost
Choosing the hardware and software components for Ceph
Ceph recommendation and performance tuning
Ceph erasure coding
Creating an erasure coded pool
Ceph cache tiering
Creating a pool for cache tiering
Creating a cache tier
Configuring a cache tier
Testing a cache tier
Introduction
In this chapter, we will learn some very interesting concepts with regard to Ceph. It includes the Hardware/Software recommendation, performance tuning for Ceph components (that is, Ceph MON, OSD), and clients including the OS tuning. Finally, we will understand the Ceph erasure coding and cache tiering, covering different the techniques of both.
