Designing Cisco Data Center Unified Fabric
Question No: 71
Given the requirements, which Cisco Nexus product is Cisco recommended?
A rich feature set that makes it well suited to top-of-rack, middle-of-row, or end-of-row access-layer applications.
Data center racks with standards-based 1 and 10 Gigabit Ethernet and FCoE features, and virtual machine awareness features that allow IT departments to consolidate networks.
A combination of high port density, lossless Ethernet, wire-speed performance, and extremely low latency that makes the switch family well suited to meet the growing demand for 10 Gigabit Ethernet.
