Requirements for Cisco UCS C-Series Servers
The illustration below shows the reference design for all
Packaged CCE deployments on UCS C-series servers and the network implementation
of the vSphere vSwitch design.
This design calls for using the
VMware NIC Teaming (without load balancing) of virtual machine network
interface controller (vmnic) interfaces in an Active/Standby configuration
through alternate and redundant hardware paths to the network.
The network side
implementation does not have to exactly match this illustration, but it must
allow for redundancy and must not allow for single points of failure affecting
both Visible and Private network communications.

which the UCS C-Series server is connected into a single virtual switch.
Network switches must be
configured properly for connection to VMware. Refer to the
Base for details on ensuring proper switch configuration to prevent
Spanning Tree Protocol (STP) delay in failover/fallback scenarios.

Design for Cisco UCS C-Series Servers
illustrates a configuration for the vSwitches and vmnic adapters on a UCS
C-Series server using the redundant Active/Standby vSwitch NIC Teaming design.
The configuration is the same for the Side A server and the Side B server.
Configure the ESXi
Host Network for the Virtual Machines
To configure the
network for VMs, you create a virtual switch connected to an Ethernet port on
the server, and then associate the virtual machine's network adapter to this
virtual switch. Perform the following procedure to create vSwitches for the
public and private networks on the Side A and B servers, referring to the
illustration above as an example.
