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.
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.
Data storage is a very important function of the data center, storing a large amount of terminal data.
Cabling, switches, routers, and firewalls are all facilities of data center network devices that connect servers to each other and to the outside network.
