Ceph PCIe SSD Performance Part 1

Description

Because Ceph is primarily a replication-based technology and does full data journaling, write performance is often a higher priority than read performance. One of the most effective ways to improve write performance is to use solid state drives (SSDs) in the cluster design. The most straightforward way to do this is to put Ceph object storage daemon (OSD) journals on SSDs. This brief focuses on how different PCIe and SATA-based SSDs can be used to store Ceph journals and improve write performance.
