This paper provides design guidelines for implementing a unified data center fabric using Cisco Nexus 5000 Series Switches and QLogic second-generation Converged Network Adapters (CNAs). Unified fabric implies that multiple types of network traffic can be present on the same physical link: for example, the fabric may transport both LAN and SAN traffic simultaneously over 10 Gigabit Ethernet. To achieve this unified approach, Fibre Channel over Ethernet (FCoE) is used to transport storage traffic over an Ethernet network. The Cisco Nexus 5000 Series offers the first unified fabric switches in the networking industry. They are field proven, with more than 1000 customers and more than a year in the market.
