Using a Fabric Extender with a Cisco Nexus 5000 Series or Cisco Nexus 6000 Series Switch

This chapter describes the Cisco Nexus Fabric Extenders (FEXs) and includes these sections:

Information About Using a Fabric Extender with a Cisco Nexus Switch

The Cisco Nexus Fabric Extenders (FEXs) support 100M/1G/10G Ethernet environments while allowing transparent migration to 10-Gigabit Ethernet virtual machine aware unified fabric technologies. The Cisco Nexus FEXs behave as remote I/O modules for a parent Cisco Nexus switch. The FEX is an extension of the parent Cisco Nexus switch fabric, with the FEX and the parent Cisco Nexus switch together forming a virtual modular system.

A Cisco Nexus FEX forwards all the traffic to the parent Cisco Nexus Switch over 10/40-Gigabit Ethernet uplinks. Passing all traffic to the parent switch allows traffic to be shaped according to policies established on the parent Cisco Nexus switch with a single point of management.

Cisco Nexus 2300 Series

The Cisco Nexus 2300 Series FEXs are stackable, hardware capable, 1 RU FEXs that support 32 or 48 100M/1G/10G host ports as well as four to six 40G uplink ports towards the parent switch. The 40G uplinks support bi-di optics for seamlessly connectivity. The platform has a deep 32MB shared buffer for increased performance.

The Cisco Nexus 2332TQ and Cisco Nexus 2348TQ provide 32 and 48 100M/1G/10GBASE-T host ports, respectively, while the Cisco Nexus 2348UPQ provides 48 1/10G host unified ports. The unified ports provide native Fibre Channel as well as 1/10G Ethernet and FCoE connectivity options.

You can order the platform with port side exhaust or port side intake air cooling. The port side exhaust cooling model is compatible with data center hot-aisle and cold-aisle designs. This orientation places the ports on the hot aisle aligned with the server ports. Port side intake airflow is used in network rack designs in the data center such that the ports face the cold aisle. The Cisco Nexus 2300 Series is built for non-stop operation, with redundant hot-swappable power supplies and redundant hot-swappable fans.

The Cisco Nexus 2300 Series platform is managed and configured by the upstream switch. The FEX software ships with the Cisco Nexus switch software. The FEX downloads the software image from the switch the same way that a module would download it from the supervisor in a modular chassis.


Note For the most current list of supported features, refer to the latest Cisco Nexus 2000 Series Fabric Extenders Release Notes at every release.


This section includes the following topics:

Chassis

The Cisco Nexus 2300 Series platform has a one-rack-unit (1 RU) form factor that takes up relatively little space, making it easy to incorporate into rack designs. The FEX is mounted in a standard 19-inch (48.26 cm) rack. All switch ports at the rear of the unit are in close proximity to server ports, and all user-serviceable components are accessible from the fan side panel.

You can order it with port side exhaust or port side intake air cooling, and with AC or DC power supplies. The port side intake cooling model is intended for installations or deployments where the ports are in the cold aisle, and the fans and power supplies are in the warm aisle.

Figure 1-1 shows the fan side view of the Cisco Nexus 2300 Series chassis. For the port side view, see these figures, depending on the FEX model:

You can order the Cisco Nexus 2300 Series platform with AC power supplies that have port-side exhaust or port-side intake airflow for cooling or DC power supplies that offer port-side exhaust and port-side intake airflow. The port-side intake airflow components have a black stripe on their front surface for easy visual identification. The port-side exhaust airflow components do not have a black stripe.


Note Colored handles on each power supply clearly indicate the airflow direction.



Caution Be sure that all of the power supply and fan modules in the same chassis have the same airflow direction and that the air intake for those modules is positioned on a cool aisle. If you install a module that uses a different direction of airflow than the other modules in the same switch, the switch can overheat and shut down. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can over heat and shut down.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use a blank filler panel (part number N2200-P-BLNK) to cover the empty slot. Figure 1-38Figure 1-9 shows a blank power supply filler panel.

The Cisco Nexus 2248PQ is managed and configured by the upstream switch. The FEX software ships with the Cisco Nexus 5500 Series switch software. The FEX downloads the software image from the switch the same way that a module would download it from the supervisor in a modular chassis.

This section includes the following topics:

Chassis

The Cisco Nexus 2248PQ FEX chassis has a height of 1.72 inches (4.37 cm), a width of 17.3 inches (43.94 cm), and a depth of 17.7 inches (44.96 cm). It weighs 17.5 pounds (8.0 kg). Its one-rack-unit (1 RU) form factor takes up relatively little space, making it easy to incorporate into rack designs. The FEX is mounted in a standard 19-inch (48.26 cm) rack. All of the switch ports at the rear of the chassis are in close proximity to server ports, and all user-serviceable components are accessible from the fan side.

You can order port-side exhaust airflow or port-side intake airflow for cooling. If you are going to install the chassis with its fan side facing the cold aisle, you must order the chassis with port-side exhaust air flow. If you are going to install the chassis with its back end facing the cold aisle, you must order the chassis with port-side intake airflow.

Ports

The Cisco Nexus 2248PQ FEX supports a total of 48 1/10-Gigabit Ethernet/Fibre Channel over Ethernet (FCoE) ports (SFP+) and 4 QSFP+ (16 10-Gigabit) fabric ports. The Cisco Nexus 2248PQ provides two types of ports: ports for end-host attachments and uplink ports. Uplink ports are differentiated with yellow for connectivity to the upstream parent Cisco Nexus 5000 Series switch.

The Cisco Nexus 2248PQ 10GE Fabric Extender supports FCoE and Data Center Bridging (DCB) which increases the reliability, efficiency, and scalability of Ethernet networks by allowing the switches to support multiple traffic classes over a lossless Ethernet fabric, enabling consolidation of LAN, SAN, and cluster environments.
