Ceph environment setup (2)1. There are three layout hosts: node1, node2, and node3. Each host has three osdks, as shown in figure. osd1, and 8 are SSD disks, 4 is the SATA disk. Each of the three hosts has a Monitor and an MDS. We use osd1, 3, and 4 to create a pool named ssd, in the form of three copies, osd0, and 2, 4 to build a Pool named sata, in the form of Erasure code, k = 2, m = 1, that is, use two osdks to store data fragments, one osd to sto

Someone asked me, how did you manage to do the unified storage? I smiled, loudly told him: Ceph in hand, the world I have. Ceph is a unified distributed storage system designed for outstanding performance, reliability, and scalability. After the adoption of OpenStack as the eldest brother is a very out of hand, by everyone's extensive attention. Of course, thi

Openstack Object Storage (Swift)Swift is an OpenStack object storage (object Storage) project that is extensible and provides a redundant storage system.objects and files are distributed on disks of multiple servers in the same cluster, and OpenStack is responsible for data replication and consistency.The object st

As an architect in the storage industry, I have a special liking for file systems. These systems are used to store the user interfaces of the system. Although they tend to provide a series of similar functions, they can also provide significantly different functions. CEpH is no exception. It also provides some of the most interesting features you can find in the file system. CEpH was initially a PhD resea

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
