Are there any companies in China using the open-source ceph distributed storage system at present?

1. Finally, Ceph is an open source distributed storage and a part of the main Linux kernel (34). Now, let's discuss the architecture of Ceph and the core elements of high-end. Then I will expand to another level, explain some key aspects of Ceph, and provide a more detailed discussion.

2. CephCeph first originated from the work and results of Sage's doctoral studies in 2004, and then contributed to the open source community. After years of development, it has been supported by many cloud computing and storage manufacturers, and has become the most widely used open source distributed storage platform.

3. Ceph: Ceph is an open source distributed storage system that adopts a scalable object storage model. It has the characteristics of high reliability, high scalability and high performance, and excels in large-scale data storage.

4. Introduction to Ceph Ceph is a unified distributed storage system designed to provide better performance, reliability and scalability. The Ceph project originated from Sage's study.Work during the doctoral period (the earliest results were published in 2004), and then contributed to the open source community.

What are the database management systems

At present, the commonly used database management systems include oracle, Sybase, VisualFoxPro, Informix, SQL Serve R, Access, etc.

Database management systems include Oracle, Sybase, Informix, MicrosoftSQLServer, Microsoft Access, etc. Oracle is the abbreviation of Oracle Database, or Oracle RDBMS.It is the relationship database management system of Oracle Company. It is a product that is in the first position in the database domain.

Non-relational database management system (NoSQL): Common non-relational database management systems include MongoDB, Cassandra, Redis, Couchbase, etc. Embedded database management system: Common embedded database management systems include SQLite, HDerby, etc.

Mysql MySQL is one of the most popular relational database management systems. In terms of WEB applications, MySQL is also one of the best RDBMS application software.

oracle, Haowu is in a hegemonic position, characterized by a sound system, high processing efficiency, safety and reliability;In the face of different application scenarios, it has targeted solutions, such as a single-instance database for small enterprises, a RAC scheme for high-reliability applications, a DATAGuard scheme for main and backup, and a goldengate for data synchronization.

Relational database management systems include: Oracle, MySQL database. Oracle, formerly known as SDL, was founded in 1977 by Larry Ellison and two other programmers. They developed their own fist products and sold them in large quantities in the market. In 1979, Oracle introduced the first commercial SQL relational database management system. .

Save What is a storage server?

1. Storage server refers to a server with different configurations designed for a specific goal. It is specially used for enterprises to store and manage a large amount of data. It will have some additional storage space or a server with a lot of storage space.

2. A storage server is a server that will carry a lot of special services, including storage management software, additional hardware to ensure high flexibility, RAID configuration types, and additional network connections to ensure that more desktop users connect to it and other functions.

3. Storage server refers to being designed for specific goals, so the configuration method is also different. It may be a server with a little extra storage or a large amount of storage space. Different uses: the storage server is used to provide services for storing data.

4. Data storage server is a kind of server, which is mainly used to store data. It is generally an independent unit, and some are also designed as a 4U rack type. The main ways of data storage are DAS, NAS and SAN. Data storage servers generally refer to NAS network memory.

What is distributed storage

Among which Hbase is based on HDFS, while oceanbase is its ownThe distributed file system implemented internally can also be said to be a distributed database with a distributed file system as the basic storage.

Distributed storage currencies are as follows: FilecoinFilecoin, Filecoin: The network is mainly composed of independent data storage miners, retrieval miners, and storage service customers who employ miners. Customers of storage services can be searched through the storage market and retrieval The market is two distributed, verifiable and incentive markets to hire miners.

Apache Active, RabbitMQ, RocketMQ, Apache Kafka. Distributed computing: MapReduce, Apache Hadoop. Distributed storage: Bigtable.Distributed monitoring: Nagios. Distributed version control: Mercurial. Microservice and container technology: Spring boot.
