PodArc

Django web project to build medium to large scale (not super-scale) datacenter network architectures. This database driven approach allows automation of device configurations, network topologies, and lends itself towards "SDN". Workflow is as follows...:

Build physical locations inside of the app

• Create a "Datacenter" location
• Create a "Cage" inside the "datacenter"
• Create a "Row" inside of a "Cage"
• Create a "Rack" inside of a "Row"

Create definitions of your network architecture building blocks, called "Pods"

• Using YAML, define different Pods...
• Pair of large devices
• 4x16 CLOS fabrics
• 6 TORs in a full mesh
• etc...

Finally - Build your network

• Create a "Pod" inside of a "Datacenter"
• Ghost "devices" as defined by your "pod definition" now exist in your database
• All physical interconnections now exist inside of your database (to be used later for config generation)
• Assign system MACs to "devices" for use with Zero Touch Provisioning.
• Config Generation creates individual device base configs using Jinja2 templates
• Those config files get pushed to repository and host entries are added to DHCP server for ZTP requiring download of generated configuration
• Connect "Pods" to other "Pods" to create a large datacenter network
• Uses "Pod Definition" file which reserves "network infrastructure" ports for pod interconnection
