Q:

Are data center switches hard to manage in large deployments?

by q***m on 2025-07-21 16:31:48

A:

Not at all. Most offer centralized SDN management, API support, telemetry, and integration with platforms like Ansible, making large-scale deployments manageable and efficient.

Q:

How much bandwidth can a typical data center switch handle?

by f***m on 2025-07-21 15:15:42

A:

Modern data center switches support up to 100G, 200G, and even 400G per port, with total backplane bandwidth in the Tbps range to ensure full-speed packet forwarding.
