Rolling Review Introduction: Switching Infrastructure: Page 6 of 8

Our data center consolidation project is driven by a need to reduce costs and centralize data for management and regulatory reasons. That makes data center availability critical to our IT plans. The chosen network design must increase the fault tolerance of our data center. In addition, we measure service levels for network performance, defined by availability, jitter, error rate and throughput. Network performance is used to assess the effectiveness of our IT infrastructure. The vendor should provide a network design and explain how its solution will maximize performance.

Our Objectives
We want our new network to support our IT plans for the next five years. We are adding more employees and more applications that are consuming bandwidth on the network. Equally important, our real-time media initiatives must have good response times across the LAN. We are not, however, planning on adding more IT staff, so automation and integration into our support systems are critical. We want to achieve the following goals:

• Unify our infrastructure to simplify management and deployment.

• Better support real-time media like voice and video.

• Support network access control so that security isn't compromised by roaming users.
