Major network elements chosen for the data centers included Cisco 7500 routers, Cisco Catalyst 6509 Ethernet switches and other data servers—each with unique connection requirements. After initial installation, it was highly likely that servers would be added and changed while at some point in the near-future, software would require upgrades. Experience taught network planners that new routers, switches and servers alone presented only part of a sound design for data centers on the 10/100Base-T and Gigabit Ethernet network. Network planners knew from experience that an infrastructure without proper connectivity and cable management would defeat the goal of creating highly efficient, reliable and cost-effective data centers. Specifically, network planners, following an across-the- company mandate to reduce operating costs and make smarter use of capital, determined that each data center must have the following characteristics: CASE STUDY • Quick addition, upgrade, or rearrangement of any Ethernet switch or data server with minimal service disruption • Better use of floor space, and • Highest quality and reliability of services SOLUTION—ETHERNET DISTRIBUTION FRAME Network planners met these challenges by incorporating a central patching location called an Ethernet Distribution Frame (EDF). By creating a centralized, familiar craft interface between Ethernet switching bays and data servers, network planners ensured that adding servers, upgrading switches and making other changes in the data center could be done quickly and with minimal service disruptions. The EDF provides a logical and easy-to-manage infrastructure through two design characteristics: • All network elements have permanent equipment cable connections that are, once terminated, never handled again. • All changes, circuit rerouting, .
