Current Network Definitions of Application
Cisco ACI Logical Object Model
Cisco ACI Endpoint Groups EPGs act as a container for collections of applications, orapplication components and tiers that can be used to applyforwarding and policy logic.
Cisco ACI Contracts Contracts allow for both simple and complex definition ofhow a given EPG communicates with other EPGs dependenton the requirements of a given environment.
Cisco ACI Application Network Profiles Application Network Profiles are the instantiation of acomplete application on the network.

Cisco ACI Stretched Fabric
Cisco ACI Stretched Fabric DesignInter-Pod NetworkPrimary SiteSecondary Site
Site-to-Site Connectivity OptionsACI stretched fabric site-to-site connectivity optionsinclude: Dark Fiber (up to 40km) Dense Wavelength Division Multiplexing (up to800km) Ethernet over MPLS (EoMPLS) pseudowire (up to800km)
Inter-Pod Network Not managed by the APIC Inter-Pod Network topology can be arbitrary, notmandatory to connect all spines Main Requirements:o 40G/100G interfaces to connect to the spine nodeso DHCP Relay to enable spine/leaf nodes discovery across Podso OSPF to peer with the spine nodes and learn VTEPreachabilityo Increased MTU support to handle VXLAN encapsulated traffico QoS (to prioritise intra APIC cluster communication)
Failure Scenarios
Single Link Failure between SitesInter-Pod NetworkPrimary SiteSecondary Site
Loss of a Single APIC ControllerInter-Pod NetworkPrimary SiteSecondary Site
More that three APICs in a cluster? The Data Base is distributed as active 2 backup instances(shards) for every attribute

Cisco ACI Dual Fabric

Site-to-Site Connectivity OptionsACI Dual Fabric Site-to-Site connectivity optionsinclude: vPC over dark fiber vPC over DWDM VXLAN or OTV

Integration in a Dual Fabric Design
Conclusion Cisco ACI offers two different DR approaches:o Stretched Fabric - Multi-Pod Design- Single APIC Cluster for multiple DCs- In event of 1 APIC Controller failure, you no longer canconfigure (read-only APIC mode)o Dual Fabric - Multi-Site Design- One APIC Cluster per Site- Establish policy orchestration between sites for trueActive/Active implementationBusiness needs define which approach toimplement!
