At present, there are some differences in the definitions of hyper-converged architecture among different manufacturers. According to the definition provided in the article "The Fundamentals of Hyper-converged Infrastructure" published by ActualTech Media, it is as follows: • Hardware-wise: The hyper-converged architecture integrates the independent computing, storage, and network hardware in large enterprise IT systems and combines them into a single server node, incorporating multiple hardware devices. • Software-wise: All system resources in the hyper-converged architecture are managed through a unified shared software management interface and shared with upper-layer applications. Besides the above definitions, the general public's main understanding of the hyper-converged architecture is: a unified management platform that transforms DAS (Direct Attached Storage) into a resource pool and eliminates the necessity of storage arrays. However, the main drawback of this definition is that the main goal of the hyper-converged architecture is to simplify the management of the data center and eliminate the problem of separate management in the data center, while eliminating storage arrays is only one of the more obvious characteristics of the hyper-converged architecture. • In simple terms, the hyper-converged infrastructure runs server virtualization software and storage virtualization software on business nodes, aggregates all computing nodes through the network into a unified virtual computing and virtual storage resource pool, and provides the IT infrastructure required by the data center in the form of a resource pool. • Broadly speaking, in addition to computing and storage virtualization, the hyper-converged infrastructure can also integrate network virtualization, security virtualization, and upper-layer business application services. The current consensus in the industry is that software-defined virtualized computing and distributed storage are the minimum set of the hyper-converged infrastructure.
