Building a Data Center Network
A data center has a series of complex facilities. Besides a computer system and cooperating devices (such as communications devices and storage systems), a data center requires redundant data communication connections, environment control devices, monitoring devices, and security devices.
Figure 1-8 shows a typical data center network topology. On this network, switches connect to each other and to servers using Ethernet technology and have various services deployed to provide low-latency, high-reliability services under highly concurrent scenarios.
As services in a data center require high network performance, 10G or even higher-speed Ethernet has been widely used in data centers. Data centers create chances for use of advanced Ethernet technologies and promote development of Ethernet technologies.
