Development potential of decentralized distributed storage
most of the current storage is centralized storage, which is stored in the traditional centralized server. If the server goes down or fails, or the server stops operating, a lot of data will be lost
blockchain, as a distributed database, can solve this problem well. This is determined by the technical characteristics of blockchain. The digital records on the blockchain can not be tampered with or forged. The smart contract enables us to work together more efficiently, so as to establish a credible digital economic order, improve the efficiency of data flow, break the isolated island of data, and create a new storage mode.
with the increasing number of nodes, the trend of qkfile market is becoming prominent, and the number of users will increase exponentially in the future. Distributed storage will have many applications in the future, such as data storage, file transfer, network video, social media and decentralized transaction. The control of the Internet is more and more concentrated in the hands of a few large technology companies. Its network is decentralized. Just like distributed storage, it is always community-centered and user-oriented. Distributed storage is the future of information technology and Internet functions. With distributed storage, we can create a more free, innovative and democratic online experience. It's time to take the Internet to a new stage
as a very popular star project this year, the future development of qkfile will promote the progress of the Internet and bring great benefits to the whole market. Distributed storage is based on the infrastructure of the Internet, and blockchain distributed storage is superimposed with artificial intelligence and big data. Today's central storage is a huge supplement. The arrival of the distributed era is not to replace the current central Internet, but to make the future data storage develop better and bring unimaginable vitality to the whole market ecology. First look at the consensus, then look at the application. Qkfile creates an infrastructure platform, just like Alibaba cloud, which is a video website for game makers and e-commerce. This is called the application layer. At this stage, in terms of performance, frankly speaking, compared with traditional cloud storage, it has little competitiveness. However, on the other hand, a new trust environment of decentralized storage is very important. In this environment, many related applications can naturally be derived, and the market potential is very large
although qkfile is still far away from real business, first of all, the economic model of qkfile has not been finalized. Secondly, qkfile needs to focus on the development of distributed storage, business logic and Web3.0. Only by opening up the track of distributed storage can it have the strength to lead the development of the whole instry. People realize the disadvantages of centralized storage, Many enterprises have begun to accept the distributed storage mode, that is, distributed storage DAPP applications touch users. So qkfile will definitely have more commercial applications in the future. The ability to create super local and efficient storage mode. When users want to store data on the qkfile network, they can get rid of the huge limitations of centralized storage and geographical location. Users can see the miners and their market prices of online storage, and miners compete with each other to win the storage contract. The user selects the competitive miner, the transaction is completed, the user sends the data, and then the miner stores the data. The miner must prove the correct storage of the data in order to get the qkfile reward. In the network, the storage security of data is verified by password proof. Miners submit their storage certificates to the network through the new block chain. Through the verification of the new blockchain released on the Internet, only the correct blockchain can be accepted. After a period of time, miners can get transaction storage fees and get blockchain rewards. Data will be spread where it is more needed. Rotating data will flow within the scope of the earth, and data acquisition will be continuously optimized. From small mining machine to large data center, all people can lay a new foundation for the construction of human information society and benefit from it through joint efforts.
first of all, you have to understand what hyperfusion is
hyper converged infrastructure (or "HCI") is also known as hyper converged architecture, which means that in the same unit device (x86 server), there are not only resources and technologies such as computing, network, storage and server virtualization , but also cache acceleration, data De plication, online data compression Backup software, snapshot technology and other elements, and multiple nodes can be aggregated through the network to achieve molar seamless scale-out, forming a unified resource pool
secondly, you must understand what is distributed storage
there is actually no clear definition of distributed storage, or even a unified name. In most cases, it is called distributed data store or distributed storage system
The definition of distributed data store in wiki is: distributed storage is a kind of computer network, which usually stores information in multiple nodes by means of data replicationthe definition given in the network is: distributed storage system, which stores data on multiple independent devices. The distributed network storage system adopts an extensible system structure, uses multiple storage servers to share the storage load, and uses location server to locate the storage information. It not only improves the reliability, availability and access efficiency of the system, but also is easy to expand
although the definitions of distributed storage are not exactly the same, one thing is unified, that is, distributed storage places data in multiple nodes, and nodes provide storage services through network interconnection. This is obviously different from the traditional centralized storage method
< H2 > difference and connectionthe definition of super converged infrastructure clearly includes software defined storage (SDS), which has the ability of hardware decoupling and can run on the general server. Super converged infrastructure is similar to the concept advocated by server San. Computing and storage are converged. Through the fully distributed architecture, the system reliability and availability are effectively improved, and it has the characteristics of easy expansion
because many readers are confused about the composition of super fusion, the following takes smartx's super fusion software smtx OS as an example to illustrate the relationship between distributed storage and other moles
Today, the global data storage capacity presents explosive growth, and the data of enterprises and Internet is growing at an annual rate of 50%. According to Gartner's prediction, by 2020, the global data volume will reach 35zb, equivalent to 8 billion 4tb hard disks. The change of data structure brings new challenges to storage system. Unstructured data accounts for nearly 80% of the storage system
with the development of the Internet, the main body of data creation has graally shifted from enterprises to indivial users, and most of the data generated by indivials are unstructured data such as pictures, documents and videos; Enterprise office process is more realized through the network, forms, bills, etc. are realized by unstructured digital archiving; At the same time, structured data based on database application still plays an important role in enterprises, storing a lot of core information
with the rapid increase of data services, the traditional single SAN storage or NAS storage mode can no longer meet the needs of business development. SAN storage: high cost, not suitable for Pb level large-scale storage system. Data sharing is not good, so it can not support multi-user file sharing. NAS storage: sharing network bandwidth, poor concurrency performance. With the expansion of the system, the performance will be further degraded. As a result, centralized storage is active again
What are the disadvantages of centralized storage and distributed storage? In the face of the two, how should we choose? Next, I will introce and analyze the differences between centralized storage and distributed storage, as well as the choices we should make in the application
selection of distributed and centralized storage; Uploading video stream to the center requires high environment of the computer room, large space of the computer room, load bearing, air conditioning and so on
the advantages and disadvantages of distributed storage and centralized management are that the physical media are distributed to different geographical locations; There is no requirement for the bandwidth of the backbone network when the video stream is uploaded nearby; Multiple low-end and small capacity storage devices can be deployed in a distributed way, with lower equipment price and maintenance cost; The small capacity equipment is distributed and deployed, and the requirements for the computer room environment are low
