How does switching capacity of Nexus 7710 and Nexus 7718 calculate?

Hi everybody.

I found the nexus 7700 Fabric datasheet there was 220G per slot.

For example, the nexus 7710.

There was 220G per slot per fabric module and result is 6*220G*8=10560G, duplex is  21120G=21T.

How does the 42T came from?

How does switching capacity of Nexus 7710 and Nexus 7718 calcula

Hi,

The 42 Tbps number Cisco are quoting is for the Nexus 7718 platform. If you look at the Cisco Nexus 7700 Switches Data Sheet you'll see it quotes:

The Cisco Nexus 7710 has six fabric module slots to provide simultaneously active fabric channels to each of the I/O and supervisor modules. Through the parallel forwarding fabric architecture, the Cisco Nexus 7710 can achieve 21 Tbps of forwarding capacity or more.

And for the Nexus 7718:

The Cisco Nexus 7700 18-Slot Switch has six fabric module slots to provide simultaneously active fabric channels to each of the I/O and supervisor modules. Through the parallel forwarding fabric architecture, the Cisco Nexus 7700 18-Slot Switch can achieve 42 Tbps of forwarding capacity or more.

So for the Nexus 7718 platform we have 220 Gbps * 6 Fabric Modules * 16 I/O slots totaling 21,120 Gbps. If we double that for full duplex we'll have 42,240 Gbps or 42 Tbps.

Hi Steve,

Thank you for you answer.

I saw in compare model page, there was 42T for 7710 and 83T for 7718.

Cisco Nexus 7700 10-Slot Switch

Cisco Nexus 7700 18-Slot Switch

42 Tbps

83 Tbps

Is that just in Roadmap ?
