glusterfs vs ceph

any modification or use of a dedicated API to access data in Gluster. This is useful when deploying gluster in a public cloud environment, gluster the cloud service provider-specific API, and then provides a standard POSIX interface.2. Design goalsGlusterfs's design ideas differ significantly from existing parallel/clustered/Distributed file systems. If there is no essential breakthrough in the design of glusterfs, it is difficult to compete with lus

soon be able to solve your massive storage needs. Other Distributed File systems Ceph is not unique in Distributed file system space, but it is unique in the way it manages a large-capacity storage environment. Other examples of distributed file systems include Google file system (GFS), General Parallel, file System (GPFS), and lustre, which refer only to a subset. The idea behind Ceph provides an interest

First, pre-installation preparation 1.1 Introduction to installation Environment It is recommended to install a Ceph-deploy management node and a three-node Ceph storage cluster to learn ceph, as shown in the figure. I installed the Ceph-deploy on the Node1. First three machines were prepared, the names of which wer

Extended development of ceph management platform CalamariI haven't written logs for nearly half a year. Maybe I am getting lazy. But sometimes writing something can help you accumulate it. Let's record it. I have been familiar with some related work since I joined the company for more than half a year. Currently, I am mainly engaged in the research and development of distributed systems. The current development is mainly at the management level and ha

In the previous blog post, we completed the Sonarqube deployment through Kubernetes's devlopment and service. Seems to be available, but there is still a big problem. We know that databases like MySQL need to keep data and not lose data. And the container is exactly the moment you exit, all data is lost. Once our Mysql-sonar container is restarted, any subsequent settings we make to Sonarqube will be lost. So we have to find a way to keep the MySQL data in the Mysql-sonar container. Kubernetes o

Deployment Installation Regarding the installation ceph the whole process encounters the question, as well as the reliable solution, the personal test is effective, does not represent the general colleague's viewpoint.I am using the server, so I did not engage in any user issues.

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 Ceph. although it is still version 0.94,

This is a creation in Article, where the information may have evolved or changed. In the article "using Ceph RBD to provide storage volumes for kubernetes clusters," we learned that one step in the integration process for kubernetes and Ceph is to manually create the RBD image below the Ceph OSD pool. We need to find a way to remove this manual step. The first th

Record information such as "Data A: Location (a)", query records when accessing data, obtain a location, and then read. Calculation. When storing and data A, its storage location (a) is calculated instantly. It is more convenient to feel this way. The common calculation is a consistent hash (consistent hashing),
