Application Infrastructure on Demand with Cisco UCS Director and Cisco Application Centric Infrastructure
March 2015
• A
storage endpoint group hosts the storage devices that physical servers and
virtual machines use to access their boot environments and application data.
These storage devices are virtual devices supported by a storage virtual machine
created by storage management systems such as NetApp Clustered Data ONTAP.

• A
host endpoint group contains the collection of physical servers and virtual
machines allocated to the container.
Cisco ACI Deploys a Network Container
After a client makes a service catalog choice, Cisco UCS Director pushes the
network profile that contains all the application component connectivity details to
Cisco APIC. The network profile defines a virtual overlay network that includes the
endpoint groups, the contracts for communication between them, and the services
inserted between layers. Unlike in traditional networks, Cisco ACI does not obscure
the underlying physical networks and devices and provides full visibility into the
physical infrastructure that supports each VXLAN tunnel. It can identify any packet
loss or out-of-bounds latency event and send that information to the real-time
application health monitoring function. If any network event has a negative impact on
application health, the network can be reconfigured dynamically to work around any
hot spots. This reconfiguration is a simple change in the relationship between the
virtual overlay network and the underlying leaf-and-spine architecture.

In the application profile example discussed so far, the network profile defines web,
application, and database tiers with load-balancing and firewall appliances inserted.
Figure 9 shows the creation of a network container. Using promise theory, every
switch independently implements the network profile so that the fabric can operate
autonomously, even if the APIC is not available.
