Historically, Cisco Nexus Series Switches network transport relied on two incompatible technologies: Fiber Channel (FC) and Ethernet. This separation posed challenges for customers looking to simplify their data center infrastructure. They faced the daunting choice of either dismantling their FC investments or extending FC networks, both of which were costly and complex.
To address these challenges, Cisco introduced Fiber Channel over Ethernet (FCoE) and launched the Nexus 5000 Series switches, which support FCoE. This innovation enables the consolidation of FC and Ethernet traffic, allowing Ethernet connections at various speeds to operate on a single switch.
The Cisco Nexus 5000 series switches come with several noteworthy features:
The Cisco Nexus 5000 series provides several advantages for data centers, especially in access layer applications:
The Cisco Nexus 5000 switches are divided into two series:
