The purpose of a data centre is basically to store and send large amounts of data and host systems and websites. It is vital to be secure, maintain high performance and operates focussing on energy consumption and minimising device numbers and costs, the system should be able to remain as simple as possible.
A data centre should support networking requirements for modern technologies such as cloud computing and virtualisation. The data centre should also be scalable and easily meet the requirements of network communications in peak usage.
The purpose of the network in a data centre is to connect the technology inside to the outside world, and to connect the internal systems together. Data centre networking creates a network infrastructure that is secure, stable, reliable and keeps in line with industry regulations.
A data centre network generally includes:
- Networking equipment (routers, switches, modems, etc.)
- Network cabling (LAN/WAN and network interface cabling)
- Network security (security protocols/encryption algorithms, firewalls, IDS)
- Internet connectivity (satellite, DSL, wireless, optical)
