Configuring Distributed Virtual Switches in Cisco UCS

Configuring Distributed Virtual Switches in Cisco UCS

This chapter includes the following sections:

Distributed Virtual Switches

Each VMware ESX host has its own software-based virtual switch (vSwitch) in its hypervisor that performs the switching operations between its virtual machines (VMs). The Cisco UCS distributed virtual switch (DVS) is a software-based virtual switch that runs along side the vSwitch in the ESX hypervisor, and can be distributed across multiple ESX hosts. Unlike vSwitch, which uses its own local port configuration, a DVS associated with multiple ESX hosts uses the same consistent port configuration across all ESX hosts.

After associating an ESX host to a DVS, you can migrate existing VMs from the vSwitch to the DVS, and you can create new VMs to use the DVS instead of the vSwitch. With the hardware-based VN-Link implementation, when a VM uses the DVS, all VM traffic passes through the DVS and ASIC-based switching is performed by the fabric interconnect.

In Cisco UCS Manager, DVSes are organized in the following hierarchy:

vCenter
    Folder (optional)
        Datacenter
            Folder (required)
                DVS

At the top of the hierarchy is the vCenter, which represents a VMware vCenter instance. Each vCenter contains one or more datacenters, and optionally vCenter folders with which you can organize the datacenters. Each datacenter contains one or more required datacenter folders. Datacenter folders contain the DVSes.

Configuring a Distributed Virtual Switch

Before You Begin

You must first create a datacenter in VMware vCenter. Do not create the folder inside the datacenter or the DVS in VMware vCenter.


Procedure
Step 1   In the Navigation pane, click the VM tab.
Step 2   On the VM tab, expand the All node.
Step 3   Right-click the VMWare node and choose Configure vCenter.
Step 4   On the Configure vCenter page of the Configure vCenter wizard, do the following:
  1. Complete the following fields:
    Name Description

    Name field

    The user-defined name for the VMware Virtual Center (vCenter).

    This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters, and you cannot change this name after the object has been saved.

    Description field

    The user-defined description of VMware vCenter.

    Hostname field

    The hostname or IP address of the machine that hosts VMware vCenter.

    Note   

    If you use a hostname rather than an IP address, you must configure a DNS server in Cisco UCS Manager.

  2. Click Next.
Step 5   On the Create Folder page of the Configure vCenter wizard, click one of the following:
Option Description

Next

Moves to the next page. Choose this option if the vCenter structure does not require you to include the datacenter in a high-level folder.

If you choose this option, continue with Step 7.
