10 | THE DATA CENTER JOURNAL www.datacenterjournal.com Cost Analysis e conventional approach requires extensive renovations to the data center room, such as the addition of dedicated cooling, vapor barriers, or modification for fire suppression to convert the space into an IT-ready room. Utilizing the data from a third-party data center design firm, we can calculate the capital costs and the operating costs of the two design approaches (See Table 1). As expected, while the integrated solution required a slightly greater investment for infrastructure equipment (approximately $4,000 over a conventional approach), the utilization of an integrated solution offered significant savings (28 percent or $17,000) in costs for fire sup- pression system and room preparation. Moreover, the room can still be used by people, since the integrated system is fully enclosed and therefore "room neutral." In addition to the facility-related sav- ings, the investment in containment and dedicated cooling equipment optimized for this environment also would yield signifi- cant savings on the efficiency front. Because the integrated solution employs a closed-loop cooling design as opposed to traditional dedicated cooling, the cooling system can utilize higher tem- perature return air and operate at higher efficiency. As a result, the integrated solution consumes nearly 30 percent less energy annually compared to the conven- tional infrastructure configuration. In light of these costs, the installation of an intelligent integrated solution would dictate a five year total cost of ownership of $184,000 or $25,000 (12 percent) less than its conventionally designed counterpart. is figure is a direct result of the savings gained by: • Avoiding costly room upgrades for vapor barriers and room fire suppres- sion systems • Sizing of fire suppression only for the volume of rack space, not the entire room • Pre-engineering and integration of EPO, power distribution, fire suppression, and air containment • Utilizing containment and air man- agement systems which provides for increased efficiency and capacity of the cooling system(s) • Using a backup air management system for higher availability or enhanced con- trol over a graceful shutdown e combination of the above results will also provide an improved infrastruc- ture lifecycle cost Critical questions to consider before choosing this type of solution: How much capacity will the solution need to support? A single row integrated solution is ideal for accommodating three-to-ten racks of equipment (up to approximately 36kW of IT load). For larger and higher load deployments, multiple row-based (for permanent installation) and/or modular (for temporary or mobile deployments), enclosures and systems may be more appropriate. Will you be starting "from scratch" or does your facility already have IT-ready infra- structure in place? If you have infrastructure in place and are not seeking a rapid deployment or a redeployable solution, implement- ing best-practices in cabinet or row based building blocks may be more suitable. How important is scalability to your IT needs? Many integrated solutions allow for capacity, support, and rack space addition and reconfiguration. Depending on the rate of space or capacity growth planned, appropriate self-contained integrated solutions or open infrastructure solutions should be considered. CONCLUSION Today's data center managers face new challenges not traditionally ad- dressed by the IT industry. Operating in accordance with aggressive business drivers dictated by the market, data center managers are responsible for minimiz- ing the total cost of ownership of the data center infrastructure as they meet multiple business requirements. New, integrated infrastructure solu- tions have emerged in a variety of configu- rations to address organizations' unique business needs while increasing efficiency, maintaining availability and speeding deployment. ese intelligent, integrated infra- structures allow managers to operate their data centers faster, smarter, easier and at lower costs, compared to traditional approaches to data center design, with resources aligned for optimal utilization and efficiency.
