Requirements for an active/active configuration

An active/active configuration requires proper configuration of OS and NIC teaming. An active/active configuration also requires two Virtual Connect modules and resources that meet the following requirements. For an example of an active/active configuration for an enclosure group with a single logical interconnect group, see Sample active/active configuration for single logical interconnect group.

About networks

For a single logical interconnect group configuration, create a pair of networks for each VLAN you want to connect.

  • At least one network for the first interconnect module

  • Another network for the second interconnect module using the same VLAN ID and

  • Smart Link selected on both networks.

For a multiple logical interconnect group configuration, you can use the same network in both logical interconnect groups.

For a single logical interconnect group configuration, designate a network name for a paired network using the naming convention <purpose>_<VLAN ID>_<side> where:

  • <purpose> could be dev,mgmt, or prod
  • <side> could be A or B, 1 or 2, or right or left

Uplink Sets

For a single logical interconnect group configuration, create a pair of uplink sets to associate the networks with the uplink ports on the interconnect module.
  • One set of networks assigned to the uplink set with uplinks on the first interconnect module

  • The other networks assigned to the uplink set with uplinks on the second interconnect module

  • Uplink ports in each uplink set are restricted to one interconnect

For a multiple logical interconnect group configuration, create an uplink set on the first interconnect module and an uplink set on the second interconnect module with the same networks.

For a single logical interconnect group configuration, assign names to uplink sets using the naming convention <uplink set name>_<side>, where:

  • <side> could be A or B, 1 or 2, or right or left

About network sets (optional)

One or more pairs of network sets. Each set should include only networks that are intended to be used in the same server profile connection.

For example, if Net_101_A is in uplink set US_A, which has ports from the interconnect module in bay 1, Net_101_A must be associated with the downlink port connected to the interconnect module in bay 1 (for example, LOM1:1-a)

For a single logical interconnect group configuration, designate a network set name using the naming convention <purpose>_<side>, where:

  • <purpose> could be dev,mgmt, or prod
  • <side> could be A or B, 1 or 2, or right or left

About server profiles

The physical ports to which you want to map the network or network sets. Map the profile connections to the downlink ports on the same interconnect module as the uplinks on the uplink set. This ensures that the networks associated with the uplink ports in the uplink set match the networks assigned to the profile connections in the downlink ports.

Do not select Auto for the port.
