Workload Automation
Cisco DFA workload automation refers to the ability to manage data center resources
dynamically on demand. It offers a framework to automate workload life-cycle. Cisco
DFA automates the provisioning of port profiles associated with a virtual machine or
physical server. Port profiles can be configured through the Cisco Prime DCNM CPOM
GUI or using the REST API provided by the Cisco Prime DCNM CPOM. The Cisco Prime
DCNM CPOM is also integrated with cloud stack tools such as Cisco UCS Director
OpenStack and VMware vCloud Director (vCD) to learn tenant network configurations
(Figure 3). Automation of virtual and physical services (L4-L7) are handled by Cisco
PNSC in a similar manner.

When a virtual machine is provisioned, the Cisco DFA leaf node autodetects the
virtual machine, pulls and applies the policies associated with the virtual machine,
on the connected port. The fabric tracks a virtual machine and moves these port
profiles within the fabric automatically. The Cisco DFA fabric is capable of applying this
automation workflow to a physical server alike.

Optimized Networking
Cisco DFA fabric uses a standard control-plane protocol to distribute the gateway
functions, thereby providing a scale-out architecture that limits the fault domain and
increases the resiliency of the fabric (Figure 4).

architecture, Cisco DFA uses a fabric encapsulation.
Virtual Fabrics
Cisco DFA allows creation of tenant-specific virtual fabrics and allows these virtual
fabrics to be extended anywhere within the physical data center fabric. It uses a
24-bit (16 million) segment identifier to support a large-scale virtual fabric that can
scale beyond the traditional 4000 VLANs (Figure 5).
