When an administrator first starts using the Docker container, it is often surprising that the container itself takes a non-persistent storage. When the container is removed, the container's storage is also removed. Of course, if there is no way to implement permanent storage, the use of container applications will be very limited. Fortunately, some methods can i

The block storage area requires three terms: ● _ nsconcretstackblock ● _ nsconcretglobalblock ● _ Nsconcretmallocblock The three block storage methods are described as follows: Stack, global, and heap. [Point 1] The block defined outside the function is global. In addition,

OpenStack is a cloud computing software developed by NASA and Rackspace, which is licensed by Apache License and is a free software and open source project. OpenStack is the IaaS (infrastructure, service) software that allows anyone to build and provide cloud computing services on their own. In addition, OpenStack is also used to create a "private cloud" within a firewall (private Cloud) that provides the resources shared by organizations or departments within the enterprise. The cinder provide

Objective The first two articles simply implement blockchain creation and proof of workload, but they are all in memory. The actual blockchain should be stored permanently, which makes sense. A permanent blockchain storage is started below. Knowledge points 1. GitHub Project Reference2.

Internet. In the age of value Internet, data is the cornerstone of all values. The value of the Internet, which is represented by block chain technology, is leading us into the new data age. With the popularization of IoT, Edge computing and artificial intelligence, the new data age is coming. We know that most of the current mainstream cloud storage is based on data centralized processing methods. It is

Block Storage SystemDistributed storage has excellent performance, can carry a lot of failures, it is easy to scale, so we use ceph to build a high-performance, high-reliability block storage system, and use it to support the public cloud and managed Cloud cloud host, the Cl

After studying the neutron, continue Nova's peripheral study tour. This site is a research block storage service cinder.0. Verifying the EnvironmentThe environment includes:1, a controller node, running NOVA-API, Nova-scheduler, Cinder-api, Cinder-scheduler, MySQL, RABBITMQ2, a Nova compute node, running a virtual machine3, three cinder volume nodes, each node uses Lvmiscsidriver to use local storage4.

Data such as chunks and transactions are ultimately stored in the LEVELDB database, and this article describes the storage formats for chunks and transactions in Leveldb. All code related to chunk storage and reading is encapsulated in Core/database_util.go, which allows you to figure out how chunks, transactions, and other data structures are stored in the database. Chunk

I. If you use only global or static variables or do not use external variables, the code for block blocks is stored in the global zone;Two. If an external variable is used, the code for block blocks in arc is stored in the heap area;In the MRC, Block fast code is stored in the stack area;Three. block by default, extern

As an excellent open-source database software, PostgreSQL is worth learning deeply. First, summarize the Storage Architecture of the PostgreSQL database. The traditional storage structure of relational databases uses table space management, which involves storage concepts such as extent, segment, page, and file. Table space management methods include SMS and DMS.
