Typically, there are three major efficiency issues within the Data Center: the need to efficiently cool the IT load, manage the use of power and optimize the use of available space. The end goal is to increase density of bandwidth by maximizing processing capacity while minimizing the Data Center's footprint and reduce operational costs. The challenge is that these efficiencies tend to work against each other.
For example, as the IT load increases with high-density active equipment, the system's power and cooling requirements are increased — and so are the energy costs. Because these three issues are directly interrelated, complications can arise from each system being manufactured, installed and supported by different vendors. That's why a universal approach, like the one Belden offers, is so important.
Belden solutions effectively deal with the cooling, power and density paradox at the rack/enclosure level with air flow, power distribution and power and climate monitoring devices that effectively contend with high density computing environments and with high-density racks, enclosures, cabling system components and cable management solutions that help offset the cooling-power dilemma.
Also included in Belden's line of solutions are:
(A) Entrance/Telecommunications Room: The entrance room of the Data Center is the location for access provider equipment, demarcation points and interface with other campus locations. The TIA-942 standard recommends locating the entrance room outside of the computer room for security purposes.
(B) Zone Distribution Area: The optional ZDA acts as a consolidation point within the horizontal cabling run between the HDA and Equipment Distribution Area. The ZDA allows frequent reconfiguration and provides additional flexibility.
(C) Main Distribution Area & Horizontal Distribution Area: The MDA houses the main cross connect and the core routers and switches. The HDA houses cross-connects and active equipment (switches) for connecting to the equipment distribution area and storage area network (SAN). Per the TIA-942 standard, both the MDA and HDA require separate racks for fiber, UTP and coax cable.
(D) Equipment Distribution Area: The EDA is where equipment enclosures and racks house the servers and where the horizontal cabling from the HDA is terminated at patch panels. In the EDA, racks and cabinets should be arranged in a hot aisle/cold aisle configuration along with airflow systems that maintain proper separation of supply (cold) and exhaust (hot) air. Belden offers a variety of products for the EDA, including our high-end freestanding enclosures that help provide optimal airflow and ease of management.
(E) Storage Area Network: The SAN houses all data storage devices such as disk arrays, tape libraries and high-capacity optical disk libraries for applications like video surveillance. The use of a separate SAN eliminates the need to store data directly on servers, which provides better network capacity. Access to stored data must be fast, requiring high-speed connections from the HDA.
(F) Backbone Cabling & Horizontal Cabling: The backbone cabling within the Data Center provides the critical connections between the entrance room, MDA and HDA. The backbone cabling in many of today’s Data Centers supports 10 Gigabit transmission speeds for current and future applications. The horizontal cabling within the Data Center provides the
connection between the HDA and EDA and SAN, including the optional ZDA.
(G) Support Offices and Open Areas: Whether it’s cubicles, conference rooms, hallways or cafeterias, there are many areas throughout a facility or campus where people conduct day-to-day activities. From wired and wireless voice and data systems to fire alarm and security surveillance, Belden offers a variety of products that deliver these systems to where it matters most.
