DATA CENTER IN A CAMPUS
You all know that the data is stored in server.Nowadays the data goes on increasing so we require a lot of servers to store them. These servers are put in place under a maintainance called Data Center. Data centers are simply centralized locations where computing and networking equipment is concentrated for the purpose of collecting, storing, processing, distributing or allowing access to large amounts of data.
A data center is a facility that centralizes an organization’s shared IT operations and equipment for the purposes of storing, processing, and disseminating data and applications. Because they house an organization’s most critical and proprietary assets, data centers are vital to the continuity of daily operations.
As you can see in above figure, the individual department LAN’s are interconnected through routers and switches and the whole set up is centered at one spot i.e switch or server. Anyone in the campus can have access the data through switch as it acts as data center of campus. Suppose a student from hostel wants to access the moodle he/she can access it irrespective of time . User can sent connection request to the other user sitting in next department in no time to achieve the the task via switches.
