Software-defined storage (SDN) is a big industry development trend, which also includes software-defined network (SDN) and software-defined data center (SDDC). Similar to SDN, software-defined storage can ensure more flexible management of storage access of the system at an accurate level.
Software-defined storage is abstracted from hardware storage, which also means that it can be turned into a * * * shared pool that is not limited by physical systems, thus making the most effective use of resources. It can also be deployed and provided through software and management, and can be further simplified through policy-based automated management.
