Typical configurations
The following typical configurations are described:
Inter-Switch Links
Direct connection without ToR switches
Virtual Link Aggregation
Multiple connection types
EN4023 in the VCS network
In all scenarios, each port of the compute node's NIC can be divided into up to four virtual NICs (vNICs), adding
more granularity in configuring virtualized network environments, if needed.
Inter-Switch Links
In this topology, EN4023 switches are connected to the Brocade VDX switches via Inter-Switch Links (ISLs)
forming a scale-out self-aggregated data center edge fabric that is based on Brocade VCS technology. Such a
fabric, where STP is eliminated, is highly resilient and efficient, and it allows network administrators to manage
the entire network as a single logical switch.
The connectivity topology, which can be used with the EN4023 switches and the Brocade VDX upstream
network devices, is shown in the following figure.
