Appendix B: Case studies > The Case of Limited Capacity - Pg. 448

448 APPENDIX B Case studies THE CASE OF MANAGING A GROWING DATA CENTER GrowingUp, Inc. has been increasingly successful since its formation not so long ago. The CIO of GrowingUp realizes that his data center will continue to grow as business continues to be successful. He also understands how quickly data center growth can make the management of critical systems and their data a losing battle for his engineers and their managers. The CIO makes the decision to plan ahead for future growth and management. Creating a task force of engineers and technical leads, the CIO is able to properly design and implement a fully dynamic data center that will allow not only for proper growth, but also the proper monitoring of that growth and the systems and data involved. The results are a truly dynamic data center that is easily auditable and reportable, not only to the engineers who designed it, but also internal and external audit and regulatory organizations. THE CASE OF LIMITED CAPACITY Undersized, Inc. was in a pickle. It needed to implement new accounting and payroll systems, but had nearly reached the capacity of their data cen- ter and could only add a few more servers. The two new applications would require 18 servers be added in order to support production, develop- ment, and testing environments. Undersized, Inc. had plenty of floor space open, but no employees had thought about the company's power and cooling resources until they were faced with the grim prospect of pulling additional power and adding more air-handling units. The costs promised to be enormous and were not forecast into the company's annual budget. The IT department at Undersized, Inc. needed to devise a plan quickly that would support the new applications, not exceed the capacity of its data center, and be far less expensive than upgrading its power and cooling infrastructure. The accounting and payroll applications were very similar in their hard- ware requirements. Each would require a database server and two applica- tion servers per instance. Two applications, times three instances (production, development, and testing), times three servers left them with a need for 18 new servers, but capacity for only six. Faced with the chal- lenge of getting more out of less the IT team turned to thoughts of virtualization with Hyper-V. They worked closely with the software vendors to define their recommended requirements for memory and proc- essors. They also confirmed that the vendors would support running their applications in a virtual environment.
