Centralized DNA deployment

[techno.it]

Hey,

We are in the process of deployment of a centralized DNAC for Assurance Purposes. Our network consists of a total of four sites. Geographically located in same country. Each site accommodates more than 3000 endpoints, 60 network devices, and a Pair of 2 WLCs. These sites are interconnected via IPsec tunnels, with latency ranging from 50 to 70 milliseconds.

DNAC cluster will be installed at HQ Data Center. And HQ Data Center has got both DC firewalls and Internet Edge Firewalls. Server farms within the Data Center are segmented by the DC firewall, and we intend to deploy DNAC within the Server block by connecting to the Servers' Top of Rack Access switches.

In this context, what would be the most optimal deployment strategies to ensure effective Assurance, Software Upgrade, SWIM, Wireless Heat Mapping, and Endpoint health monitoring?

I do not see any issue as per your RTT mentioned -

Look at the Datasheet RTT - as long as you are not beyond motioned RTT you are good.

Maximum latency supported, roundtrip time. Latency Requirements and Round-Trip Time (RTT): The latency between the DNA Center appliance and a managed device should be ~100 milliseconds RTT or less. Longer execution times could be experienced for certain events after 100 milliseconds, such as Inventory Collection, Fabric Provisioning, and Image Update (SWIM). Cisco does not support a Round-Trip Time (RTT) of more than 200 milliseconds.

Note : Choose the Right DNAC Cluster deployment  - Right sizing and  I take this as 3 node cluster.
