Cisco ACI’s Multi-Hypervisor + BareMetal Interop with VLAN and VXLAN Routing and Bridging Demonstration

In November last year, I introduced via my blog, the powerful capabilities of the ACI Fabric and the unique hardware based VXLAN implementation in Cisco Nexus 9000 Series switching platform. In this blog, I am happy to present a powerful Video based demonstration of the ACI Fabric. The demo presents a single view of an entire spine-leaf fabric based deployment, and how the fabric allows full integration and full normalization of any encapsulatio…

ACI Design Principles: The role of SDN Overlays in Application Centric Deployments – Part 1

This is a two-part blog series developed in association with Tom Edsall, a Cisco Fellow and CTO of Insieme Networks, recently acquired by Cisco Systems. The intent is to elaborate on foundational design principles of Application Centric Infrastructure (ACI), a transformational approach for next-generation and cloud deployments. While the vision of ACI is an expansive one, this blog series focuses on the role of SDN overlays, their deployment con…
