The Cisco Nexus 93180LC-EX Switch is a data plane switch that provides 24 40 Gbps QSFP ports and six 40/100 Gbps QSFP or QSFP28 uplink ports.
This switch can be used for the ToR network and for extra switch pairs to support Isilon connectivity.
The Cisco Nexus 93180LC-EX Switch is for solutions that include:
Odd-numbered ports 1, 3, 5, through 23 can be configured as 4x10 Gbps breakouts to facilitate 10 Gbps connections to SFP+ based devices. When one of these ports is configured as a breakout, the even-numbered port below it is disabled. Ports 25 and 27 are dedicated as 100 Gbps vPC peer links, and ports 26 and 28 are disabled. Uplink ports 29 through 32 can be configured as 40 Gbps, 100 Gbps, or 4x10 Gbps breakouts to facilitate connections to external networks.
Cisco UCS uplinks
Uplinks from the Cisco UCS 6332-16UP Fabric Interconnects to the Cisco Nexus 93180YC-FX Switch use:
Each pair of Cisco UCS FIs consumes four QSFP ports on each Cisco Nexus 93180LC-EX Switch for a standard uplink topology. Six QSFP ports on each Cisco Nexus 93180LC-EX Switch provide enhanced bandwidth uplink technology.
Storage array NAS connections
A Cisco QSFP-40G-SR4 transceiver provides connectivity from the 10 Gbps NAS ports on a VxBlock System 1000 storage array to the Cisco Nexus 93180LC-EX Switch.
A combination of MPO-to-LC hydra cables, MPO trunks, and MPO-to-LC cassettes are used to provide fiber connectivity to the endpoint.
The NAS device is populated with 10 Gbps optical SFP+ modules. A direct-attach QSFP cable that is provided with the node connects to a 40 Gbps Isilon node. NAS devices are cross-connected to both switches.
One connection from each AMP node is made to each ToR Cisco Nexus 93180LC-EX Switch using Cisco QSFP-40G-SR4 transceiver.
A combination of MPO-to-LC hydra cables, MPO trunks, and MPO-to-LC cassettes are used to provide fiber connectivity to the endpoint. Fiber connectivity provides four 10 Gbps LC fiber connections from each QSFP module. These connections are used for data-plane traffic, such as connections to the VMware vSphere ESXi Management network from workloads residing on the AMP.
vPC peer link
Two 100 Gbps copper direct-attach connections form the vPC peer link between the Cisco Nexus 93180LC-EX Switches.
The following connections to the external network are supported:
Minimum uplinks per switch pair
Maximum uplinks per switch pair
OM4 MPO MMF
100 M for OM3,
150 M for OM4
MPO MMF terminated with LC
100 M for OM3,
150 M for OM4
Integrated Data Protection connections
Most Dell EMC Integrated Data Protection solutions include a pair of dedicated Cisco Nexus 93180YC-EX Switches, which are uplinked to the Cisco Nexus 93180LC-EX Switches using 40 Gbps QSFP direct-attach cables.
For small deployments, the Cisco QSFP-40G-SR4 transceiver uses the same connection method as NAS to provide direct connectivity from the data protection components to the switches. This method provides four 10 Gbps LC fiber connections from each QSFP module. In-band management connections from the Integrated Data Protection components use 1 Gbps GLC-T SFP+ to Cat6 connections.
For small Isilon deployments, the Cisco Nexus 9336C-FX2 Switches can connect:
