SDA Fabric Boarder -> Hardware Roadmap -> Nexus 9k ?

[roward]

My customer is planning a Campus + Mini DC refresh at one of their sites… Nexus 7700 is too big for their needs, they are planning to use two N9ks in the DC, ISR4k or ASR1k for the WAN and Cat9300 in the access…. Could you steer them to any particular N9k model to enable an internal SDA boarder node implementation in the future without buying a pair of cat9500s?

Same question another way:

Quick question on SDA roadmap for internal Fabric Boarder nodes: Right now we have support on Nexus 7700 (with the right Sup/Cards)… will there be any support on Nexus 9k for the smaller DC environment?...

Kind regards,

Rob.

Hi Rob.

There are no plans to support Nexus 9K as part of DNA and/or SDA.

Since SDA fabric is an overlay based solution, it is possible to use N9K (or others) as underlay transport devices. Note that additional underlay capabilities/enhancements are being added to the C9K series for SDA.

So, in the topology that you describe above: the ideal design (w/o C9500's) would be to use the ASR1K or ISR4K as the SDA Control-Plane (CP) + Border nodes, connected (via 1/10G) to the Catalyst 9300 Edge nodes.

This is a tested/supported design, useful for small fabric domains.
