We will describe a sample DC in this section to show the actual use of the technologies discussed in the preceding sections.
A data center is the most crucial part in an organization's IT network. All services in the organization's IT environment, including business critical databases and applications, are hosted within the data center. Any outage in these services or applications can lead to a loss of revenue for the organization and therefore building redundancy into the overall data center design is paramount. This redundancy has to be built to cater to all failure scenarios including network failure, firewall failure, server failure, and so on. We will discuss the various techniques and designs used to build redundancy in the DC in the sample DC configurations.
A sample DC design from a physical topology perspective is shown in the following...
