Abstract: A virtual port group abstraction can facilitate automated configuration of devices in a data center. For example, a data center administrator can define a virtual port group to include a set of logical and physical interfaces for devices allocated to a particular department or other group within a company. An administrator for the department can then utilize a user interface to perform actions with respect to the virtual port group. The actions can include configuration actions, modeling actions and/or deployment actions. An action received by a network management controller such as a Software-Defined Networking (SDN) controller can be converted into the appropriate actions for the relevant logical and physical interfaces that are configured to be part of the virtual port group.

Abstract: A system for configuring a data center includes a fabric management server coupled to a management switch. A provisional Software Defined Networking (SDN) controller executing on the fabric management server can discover physical servers coupled to the management switch, receive network interface configuration information from the physical servers, and use the discovered network interface configuration information to determine a configuration for switches and servers coupled to an IP fabric. The configuration can be migrated to a full functionality SDN controller.

Abstract: A method includes deploying a network device within a fabric having a management network by attaching the network device through the management network to a port of a role allocator, wherein the role allocator includes one or more ports designated as first level port connections and one or more other ports designated as second level port connections. If the deployed network device is attached to one of the ports designated as first level port connections, the deployed network device is configured as a first level device. If the deployed network device is attached to one of the ports designated as second level port connections, the deployed network device is configured as a second level device.

Abstract: An example method includes determining, by a network controller, based on a high-level data model, vendor-agnostic device information for a first network device, translating the vendor-agnostic device information into vendor-specific device information, sending, to the first network device, first configuration information included in the vendor-specific device information to cause the first network device to switch into a maintenance mode and enable diversion of network traffic from the first network device to a second network device, responsive to verifying that the first network device has diverted the traffic, initiating maintenance procedures on the first network device while the first network device is in the maintenance mode, and sending, to the first network device, second configuration information included in the vendor-specific device information to cause the first network device to switch out of the maintenance mode and enable reversion of network traffic from the second device to the first network device.

Abstract: Techniques are described for detecting failure of one or more virtual computing environments and causing a migration of workloads. In some examples, a computing system includes a storage medium and processing circuitry having access to the storage medium. The processing circuitry is configured to communicate with a plurality of virtual computing environments (VCEs), including a first VCE and a second VCE, wherein each of the plurality of VCEs is operated by a different public cloud provider. The processing circuitry is further configured to deploy a group of workloads to the first VCE, detect a failure of at least a portion of the first VCE, and output, to the first VCE and responsive to detecting the failure, an instruction to transfer a set of workloads of the group of workloads to the second VCE to thereby cause a migration of the set of workloads to the second VCE.
