White Paper: Simplify VMware vSphere* 4 Networking

Advances in Intel® Ethernet 10 Gigabit (10GbE) Server Adapters and VMware vSphere* 4 enable migration away from legacy Gigabit Ethernet (GbE) networking. As the industry move toward 10GbE becomes more mainstream, IT organizations are considering its use for initiatives such as LAN/SAN consolidation and unification. Many of these organizations have found success with the practical first step of converging multiple LAN connections using 10GbE. This transition lowers the number of physical connections required, thus reducing overall complexity and cost, while providing advanced security and traffic segmentation.

Networking virtualized hosts with GbE is typically based on relatively large numbers of dedicated physical connections, which are used both to segregate different types of traffic and to provide sufficient bandwidth. Using 10GbE connectivity can help overcome shortcomings of the approach, including the following:
• Excessive complexity. Large numbers of server adapters and the attendant cabling make administration less efficient and increase the likelihood of connection and configuration errors.
• High equipment costs. Using many GbE network adapters requires the purchase of the actual adapters, as well as the use of large numbers of motherboard slots, switch ports, cables, and so on.
• Increased energy use. Powering many individual GbE server adapters and switch ports directly increases power usage and raises server-room cooling requirements .

This paper provides network architects and decision makers with guidance for moving from GbE to 10GbE networking in their virtualized data centers. It begins with a review of the current state of the typical virtualized data center and discusses some of the challenges and opportunities associated with maximizing the value of virtualization. Next, it explores the factors that underlie the excessive complexity associated with GbE networking and describes how 10GbE can address that complexity. It then provides some best practices for achieving optimal networking results in virtual infrastructures. Finally, it addresses some concerns decision makers might have with regard to security and performance.
