About active/standby configurations

An active/standby configuration is an Ethernet network configuration where servers in the enclosure have two NIC ports connected to the same Virtual Connect network. A single uplink set has uplinks in both interconnects. The uplinks in one interconnect are active; the uplinks in the other interconnect are standby and available in the event of a network or interconnect failure. Communications between servers do not leave the interconnect module. For external communications, all servers in the enclosure use the active uplink, regardless of which NIC is actively passing traffic.

An active/standby configuration:

  • Provides predictable bandwidth.

  • Does not oversubscribe top-of-rack switch (ToR) bandwidth.

An active/standby configuration has the following requirements:

  • A minimum of one Ethernet network and one uplink set for each external VLAN ID you define.
