Routers, switches, firewalls, servers, storage systems, application delivery controllers etc., as the essential infrastructure for data center design, together form the core components of the data center: computing, storage, and network. Three core components help ensure data security and availability.
Computing resources
The processing and memory for running applications on a server may be virtualized, physical, distributed among containers or distributed among remote nodes. But these servers can do data processing, storage, and network connectivity for applications.
Storage infrastructure
Data storage is a very important function of the data center, storing a large amount of terminal data.
Network infrastructure
Cabling, switches, routers, and firewalls are all facilities of data center network devices that connect servers to each other and to the outside network.
