    摘要: Aspects of the present invention include an N-Node virtual link trunking (VLT) system comprising a set of N nodes collectively provide a logical fabric-level view that is consistent across the set of N nodes. Embodiments of the N-Node VLT system comprise a control plane mechanism to provide Layer 2 multipathing between access network devices (switches or servers) and the core network. The N-Node VLT system provides a loop-free topology with active-active load-sharing of uplinks from access to the core. Accordingly, the N-Node VLT system eliminates the disadvantage of Spanning Tree Protocol (STP) (active-standby links) by allowing link aggregation group (LAG) terminations on multiple separate distribution or core switches and also supporting a loop-free topology. Additional benefits of an N-Node VLT system include, but are not limited to, higher resiliency, improved link utilization, and improved manageability of the network.

    摘要: A system and method for a flexible switching fabric includes a network switching device. The network switching device includes a plurality of connectors configured to couple the network switching device to other network devices, one or more front panel cards, each front panel card including one or more first ports and configured to forward network packets between the first ports, one or more fabric cards, each fabric card including one or more second ports and configured to forward network packets between the second ports, and a port multiplexing unit configured to flexibly couple the plurality of connectors to the one or more first ports and the one or more second ports to the one or more first ports. The flexible coupling between the one or more first ports and the plurality of connectors and the one or more second ports is determined based on a desired configuration for the network switching device.

    摘要: An information handling system is provided. The information handling system includes a first hypervisor running on a first host and a second hypervisor running on a second host. The first hypervisor managing a first virtual switch, and the second hypervisor managing a second virtual switch. The information handling system also includes a plurality of virtual machines (VMs), including a first VM, which is part of a first tenant, running on the first host, and a second VM, part of a second tenant, running on the second host. The first virtual switch has a mapping in memory that maps a customer-specific multicast IP address, used by the plurality of VMs to indicate a multicast group that includes VMs on the first and second tenants, to a global multicast IP address used by the first and second hosts.

    摘要: Systems and methods are provided that allow for the management of switching devices in an information handling system without having to access the switching device. An information handling system as provided herein includes at least one switching device and a controlling device in communication with the at least one switching device. The controlling device includes a network interface component configured to receive a request from the at least one switching device, and one or more processors. The one or more processors are configured to provide configuration settings and an operating system to the at least one switching device in response to the received request, record network traffic of the at least one switching device, provide the recorded traffic to an analytics engine, and debug the at least one switching device based on information received from the analytics engine.
