OverviewDocs:http://docs.ceph.com/docsCeph is a distributed file system that adds replication and fault tolerance while maintaining POSIX compatibility. The most characteristic of Ceph is the distributed meta-data server, which distributes the file location by crush (controlled Replication under scalable Hashing) this quasi-algorithm. The core of Ceph is the Rados (reliableautonomic distributed Object Store), an object cluster store, which itself provides high availability, error detection, and

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

With the development of science and technology in the times, no matter what kind of enterprises have strict requirements on their own hardware facilities, the most popular switch is the so-called optical fiber switch, that is, a separate network of the entire storage can be connected to the enterprise LAN of the server. It is characterized by the use of fiber channels with high transmission rates to connect to the server network, or the internal components of the SAN network, so that the entire

architecture completes the main metadata management in the system by the OSD, reducing the client overhead. 3, Meta Data server (Metadata Server,mds) MDS controls the interaction of client and OSD objects, providing several features: (1) Object storage access. The MDS constructs, manages the view that describes the distribution of each file, and allows the clien

Blackberry Internet access has always been a big problem in mainland China. Many of my friends have asked me this question. I will describe it in detail here today. Problem: Blackberry cannot access the Internet, or I can access the Internet on machine A, but not on machine B? Analysis To solve this problem, we must understand the principle of Blackberry surfing the Internet. First, we will introduce the Internet access problems of other devices. Most mobile phones can directly use cmwap or cmne

, the fiber channel switch. Scalability not only refers to the capacity for increasing network bandwidth, but also whether to use the number of ports of existing fiber channel switches to effectively build a large-scale storage network. With the increasing demand for storage networks, users urgently need a high-performance, powerful storage network platform that can meet the bandwidth and port quantity requirements by scaling. Such a platform must be able to provide investment protection, that i
