Although they tend to provide a series of similar functions, they can also provide significantly different functions. CEpH is no exception.

Ceph was originally a PhD research project on storage systems, implemented by Sage Weil in University of California, Santa Cruz (UCSC). But by the end of March 2010, you can find Ceph in the mainline Linux kernel (starting with version 2.6.34). Although Ceph may not be suitable for production environments, it is useful for testing purposes. This article explores

Ceph provides three storage methods: Object Storage, block storage, and file system. The following figure shows the architecture of the Ceph storage cluster:We are mainly concerned about block storage. In the second half of the year, we will gradually transition the virtual machine backend storage from SAN to
