Abstract: A disclosed example of managing a network include receiving a packet at a first top-of-rack (ToR) switch via a first load-based teaming (LBT) port; determining whether a network location of a destination node of the packet is unknown; based on the network location being unknown, setting an LBT egress control value in the packet, the LBT egress control value to indicate that the packet is not to be transmitted via a second LBT port of a second ToR switch; and sending the packet from the first ToR switch to the second ToR switch via an inter-switch link between the first and second ToR switches and from the first ToR switch to at least a first host that is identified in the packet as the destination node.

Abstract: A disclosed example includes configuring a virtual network and a physical network for at least twenty-four hosts and a top-of-rack switch in less than one minute by: generating, by executing an instruction with one or more processors, network topologies of the hosts based on physical network connection information indicative of physical network connections between the hosts and the top-of-rack switch; determining, by executing an instruction with the one or more processors, whether implementing the network topologies of the hosts concurrently is valid based on an evaluation of the network topologies relative to a network topology validation rule; and configuring, by executing an instruction with the one or more processors, the top-of-rack switch based on one or more of the network topologies.

Abstract: Some embodiments of the invention provide a novel method of performing network slice-based operations on a data message at a hardware forwarding element (HFE) in a network. For a received data message flow, the method has the HFE identify a network slice associated with the received data message flow. This network slice in some embodiments is associated with a set of operations to be performed on the data message by several network elements, including one or more machines executing on one or more computers in the network. Once the network slice is identified, the method has the HFE process the data message flow based on a rule that applies to data messages associated with the identified slice.

Abstract: Example methods and systems for pre-validation of network configuration are disclosed. One example may comprise: detecting a request for network configuration to be implemented in a physical network environment; and identifying a set of physical network elements associated with the network configuration. The method may further comprise emulating the set of physical network elements to determine a physical network behaviour caused by the network configuration; and assessing validity of the network configuration based on the physical network behaviour. The set of physical network elements may be emulated using (a) multiple first physical network element emulators and (b) a second physical network element emulator that aggregates the multiple first physical network element emulators.

Abstract: Methods, apparatus, and articles of manufacture are disclosed to improve resource allocation for virtualized server systems. An example apparatus includes a resource identifier to identify a set of external storage resources when a host storage solution is not identified, a storage cost calculator to calculate a cost corresponding to the external storage resource set by comparing a parameter of an external storage resource in the external storage resource set to a requirement, a cost analyzer to determine whether the cost satisfies a cost threshold by comparing the cost to a cost threshold, and a workload domain allocator to allocate the external storage resource set to the workload domain when the cost satisfies the cost threshold.
