Why is there software-defined storage?

With the development of personalization, Internet of Things and Internet of Things, data is growing at an unprecedented speed, and the storage, management, optimization and utilization of data become a difficult problem. Users face the following challenges: low storage utilization rate, rigid data in some hardware components, difficulty in providing dynamically changing service levels on demand, lack of precise control, complicated process of deploying and adjusting storage resources (such as coordination between application administrators and storage administrators), and low degree of automation.

Storage-related software and hardware technologies are developing rapidly.

Software technology: the development of virtualization, distributed storage and cloud computing technology.

Hardware: SSD, CPU multi-core technology, high-speed network technology, large-capacity server and disk.

Software-defined storage has obvious advantages, taking hyper-convergence as an example.
