3 Agenda Cisco Data Center SDN Strategy Programmable Fabric with VTS VTS Architecture VTS Functionality Network Models Usecases

4 Cisco SDN: Providing Choice in Automation and Programmability Application Centric Infrastructure Programmable Fabric Programmable Network DB DB Web Web App Web App Turnkey integrated solution with security, centralized management, compliance and scale Automated application centric-policy model with embedded security Broad and deep ecosystem VxLAN-BGP EVPN standard-based 3 rd party controller support VTS for software overlay provisioning and management across N2K-N9K Modern NX-OS with enhanced NX-APIs Automation Ecosystem (Puppet, Chef, Ansible etc.) Common NX-API across N2K-N9K Mass Market (commercial, enterprises, public sector) Service Providers Mega Scale Datacenters

5 Updates on Nexus Portfolio Offerings Extended NX-API Support Across Nexus 2K-9K Application Centric Infrastructure Programmable Fabric Programmable Network DB DB Web Web App Web App NEW! ACI Release for Nexus 9000 (Shipping June 2015 ) Microsoft Azure and System Center Integration Programmability examples: vcenter plugin, ACI toolkit etc. Simplified operations Stretched fabric, multiple destinations from 30KMs to 150KMs Group-based policy on Openstack New ACI ecosystem partners (CliQr) NEW! Virtual Topology System (VTS) for software overlay provisioning and management across for Nexus 2K-9K (2H 2015) Standards-based fabric support on Nexus 5600/7x00 with VXLAN BGP EVPN (shipping with Nexus 9000 today) NEW! Unified Open NX-OS Release for Nexus 3000 and Nexus 9000 (Q3 2015) Enhancements to NX-API object store and model driven Native 3rd party RPM applications integration (tcollector, Nagios, Ganglia, Puppet / Chef etc.) Linux utilities support for seamless tool integration across compute and network SDK for custom application integration NEW! Common NX-API across N2K- N9K (2H 2015)

6 Programmable Fabric NX-API, VXLAN BGP EVPN Fabric, and Virtual Topology System (VTS) VTS NX-API BGP-EVPN VXLAN Fabric Phy sical Virtual DCI/WAN Operations / Programmability & Automation Bare Metal VM VM OS OS Virtualized Automated DCI / WAN VTS for overlay provisioning and management across Nexus 2000 Nexus 9000 (2H 2015)

7 Virtual Topology System (VTS) Overlay Provisioning & Management System vcenter GUI Flexible Overlays Physical and virtual overlays Bare-metal and Virtualized workloads REST API Automated Seamless integration with Orchestrators Overlay provisioning and DCI/WAN integration Open and Programmable REST Northbound APIs Multi-protocol and Multi-hypervisor support VTS Programmable Fabric Scalable VXLAN Management MP-BGP EVPN control plane High performance virtual forwarding Across Nexus Portfolio Nexus 2K 9K

8 VXLAN as Data Center Overlay technology VTE P IP Transport Network VTE P VXLAN VNI VTEP VTEP Local LAN Local LAN LAN Segment Local LAN Local LAN Modes of Operation: Underlay Network: IP routing proven, stable, scalable ECMP utilize all available network paths Overlay Network: Standards-based overlay Layer-2 extensibility and mobility Expanded Layer-2 name space Scalable network domain Multi-Tenancy BGP EVPN (BGP control plane with MP-BGP Extensions) Multicast based flood and learn (No control plane)

9 Advantages of EVPN Control Plane Advantages with EVPN Control Plane Industry standard protocol for multi-vendor support Built-in Multi tenancy support Truly scalable with protocol-driven control plane architecture Fast convergence upon network failures and host movements Minimize flooding through ARP suppression Security through VTEP peer-authentication

11 VTS Functionality Discovery Discover ToRs, Servers and interconnections Manage sw itch and netw ork topology status Topology information via API or GUI Automated Provisioning VXLAN Provisioning (BGP EVPN & Flood/Learn) VXLAN Overlay management (Add/Modify/Delete) Multi-tenancy support Track and Update VNIDs as VM moves Netw ork facing resource management Flexible Overlay Management Tenant to VNID mappings and VNID status VNID to VTEP mappings VTEP to VLAN and end host mapping Trace VMs connected to VTEP VTEP status w ithin a VNID VXLAN and fabric statistics

12 VTS Functionality: Discovery & Topology View

13 VTS Overlay Configuration through GUI Create a Tenant Add Network to the Tenant Add Subnet Select the ToR and host facing ports VLAN and VNID is automatically allocated Layer-2 VXLAN segment is configured on the ToR switches

14 VTS Functionality: Overlay Visibility

20 INET2 Campus Global Transport Internet (The Backbone) Firm-Wide Campus INET1 Campus Multi-tenant cloud use case In FSI, customers have used the separated or isolated infrastructures for the sake of compliances. Firewall INET1: Inv estment Banking For example, a large US FSI has the following three infrastructures: Investment Banking Intranet (INET1) Corporate Financing Intranet (INET2) Global IT Intranet (INET3) INET1 Compute Farm INET3 Global IT Intranet The hardware resource waste resulted from three sets of infrastructures is horrendous. Leveraging Cisco s software overlay SDN will allow them to tap into the unused compute capacity and avoid hardware acquisition.
