wholesale gemstone jewelry china What is the relationship between software definition storage and distributed storage?

wholesale boutique jewelry and accessories What is distributed storage
This does not have a clear definition about distributed storage, and there is no unified statement in the name. In most cases, it is called Data Store or Storage System.
The definition of the Data Store in Wikipedia is: distributed storage is a computer network, which usually stores information in multiple nodes in data replication.
The definitions given in Baidu Encyclopedia are: distributed storage system, which stores data decentralized on multiple independent devices. The distributed network storage system adopts scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate the storage information. It not only improves the reliability, availability and access efficiency of the system, but also easy to expand.
although the definitions of distributed storage are not exactly the same, one thing is unified, that is, distributed storage to disperse data in multiple nodes, and nodes provide storage services through network interconnection. This is clearly distinguished from the traditional centralized storage method of placing data sets.
What is software definition storage
sds full name is Software Defined Storage, literally meaningful translation is software definition storage. Regarding the definition of SDS, you can refer to the Global Network Storage Industry Association (SNIA). Sina officially included software definition storage (SDS) in research objects in 2013.
sina definition of software definition storage (SDS) is: a virtual storage with service management interface. SDS includes the function of storage pooling, and can define the data service characteristics of the storage pool through the service management interface. In addition, SINA also proposes that software definition storage (SDS) should have the following characteristics:
high degree of automation -by simplified management, the operation and maintenance overhead of the storage infrastructure
Standard interface -support API management, release and operation and maintenance Storage device and service
On virtualized data path -support multiple standard protocols, allow applications to store data through block storage, file storage or object storage interface to write data
The extension process does not affect the availability and does not cause performance decline
transparentness -storage should provide users with the available resources and overhead of management and monitoring storage
distributed storage and software definition storage N Software definition storage (SDS) focuses on storing resource virtualization and software definition. First of all, in terms of form, software definition storage (SDS) is different from traditional "hardware definition" storage. It does not rely on exclusive hardware and can allow storage to storage Software is running on the universal server, which can avoid hardware binding and effectively reduce the cost of hardware procurement; have standard API interfaces and automated tools to effectively reduce the difficulty of operation and maintenance. Storage resource virtualization, support a variety of storage protocols, integrate enterprise storage resources, and improve the utilization rate of storage resources. However, in terms of definition, the software definition storage (SDS) is not necessarily distributed or concentrated in terms of deployment. ) It is more distributed). The internal SDS storage may be run by stand -alone and does not store data through the network decentralization. This form of software defining storage (SDS) scalability may have relatively limited limitations.
distributed storage, its biggest feature is multi -node deployment, and data is placed through the network. The characteristic of distributed storage is strong scalability. Through multi -node balance load, the reliability and availability of the storage system are improved. Contrary to software definition storage (SDS), distributed storage is not necessarily software -defined, and it may be binding hardware. For example, IBM XIV storage, it is essentially a distributed storage, but it is actually delivered by dedicated hardware to deliver Essence Then there is still a hardware binding, which has a higher cost.
