Bandwidth required at WAN for nexus dashboard insight data ?

Jainul · ‎10-10-2022

I have 4 service node (Nexus Dashboard) and have multi-site scenario. Can I use it all 4 in a single site ? Is there any challenges in doing so?

And from the above scenario when I implement all nexus dashboard in a single site. How much bandwidth is required for nexus dashboard insight traffic at the WAN link when devices (2*Spine and 20*Leaf) sends data through WAN to other site nexus dashboard? So that I can plan the bandwidth on the WAN link accordingly. Need help urgently

Thanks in Advance.

@Gary25Bell Do you know someone .

@Jainul Hi Jainul, you can setup 3 maters nodes and 1 worker node as a cluster in a single site.

Each Nexus Dashboard cluster typically consists of 1 or 3 master nodes. For 3-node clusters, you can also provision a number of worker nodes to enable horizontal scaling and standby nodes for easy cluster recovery in case of a master node failure. For maximum number of worker and standby nodes supported in this release, see the "Verified Scalability Limits" sections of the Cisco Nexus Dashboard Release Notes.

For a details deployment model and bandwidth, you must always use the lowest RTT requirement when deploying the Nexus Dashboard cluster and services. For example, if you plan to co-host the Insights and Orchestrator services, site connectivity RTT must not exceed 50ms.

Service	Connectivity	Maximum RTT
Nexus Dashboard cluster	Between nodes	150 ms
Nexus Dashboard Orchestrator	Between nodes	150 ms
Nexus Dashboard Orchestrator	To sites	For APIC sites: 500 ms For NDFC sites: 150 ms
Nexus Dashboard Insights	Between nodes	50 ms
Nexus Dashboard Insights	To sites	50 ms
