Ceph, an open-source distributed storage platform, provides a unified interface for object-, block-, and file-level storage [33, 80, 34, 81]. This chapter presents the block-level workload characteristics of a WD WASP/EPIC microserver-based Ceph cluster. The analysis techniques presented can help you to understand the performance and drive characteristics of Ceph in production environments. In addition, I also identify whether SMR, hybrid disk, and SSD drives are suitable for the Ceph workload.

The basic architecture of Ceph was described in Chapter 1. Ceph’s core, RADOS, is a fully ...
