11.2 Cisco Nexus 5548 as LAN Top of Rack Switch

The Cisco Nexus 5548 is a 1RU 10 Gigabit Ethernet, Fibre Channel, and FCoE switch offering up to 960

Gbps of throughput and up to 48 ports. The switch has 32 fixed ports and one expansion slot. The Cisco

Nexus 55000 Series switch enables consistent low-latency Ethernet solutions, with front-to-back or

back-to-front cooling, and with data ports in the rear, bringing switching into close proximity with

servers and making cable runs short and simple. The switch series is highly serviceable, with

redundant, hot-pluggable power supplies and fan modules. It uses data center-class Cisco® NX-OS

Software for high reliability and ease of management. The Cisco Nexus 5500 platform is well suited for

enterprise-class data center server access-layer deployments across a diverse set of physical, virtual,

storage-access, and high-performance computing (HPC) data center environments.

The connectivity between Cisco Nexus 5548 switches and the blade IO modules is also similar to the

connectivity between the S4810 switches and the blade IO modules. The only difference is that the

blade IO modules connect to the Cisco Nexus 5548 virtual PortChannel (vPC) using QSFP+ optical

transceivers and QSPP+ optical breakout cables. The 40Gb ports on the IO modules have a Dell 40Gb

QSFP+ optical transceiver. The 40Gb QSPF+ optical breakout cables connect to the Cisco Nexus 5548

switches. The two Cisco Nexus 5548 switches are configured as vPC peers. The Dell IO modules

connecting to the Cisco Nexus 5548 are vPC port-channels with a throughput of 40Gbps. Figure 17

below shows the connectivity between Cisco Nexus 5548 switches and blade I/O modules.
