Single Server Dual Connectivity
The PCIe between the server board and the SIOC card is connected using BIOS.
The CMC controls the correct association of the server ID with the virtual network interfaces it creates.
This features allows you to configure a new single server dual VIC chassis property on the Cisco IMC by enabling it or disabling it using the web UI or command line interface.
Based on the Cisco IMC hardware configuration, a specific PCI connectivity is enabled on the VIC. The CMC uses the singer server dual VIC property along with the current chassis hardware configuration to identify the server ID property to be specified when you create a virtual network interface in either of the dual SIOC VICs. The VIC configuration page on the web UI displays the read-only attribute of the Server ID to which the VIC is PCIe linked, and this is used by the host server for the virtual network interface traffic.
Configuring Single Server Dual SIOC Connectivity
Before you begin
You must log in with admin privileges to perform this task.
The chassis must have a single server and two VIC adapters (SIOC).
In the Navigation pane, click the Chassis menu.
In the Chassis menu, click Summary.
In the Chassis Properties area of the Chassis Summary pane, from the Server SIOC Connectivity field, select Single Server Single SIOC or Single Server Dual SIOC.
If you have a chassis with a single server and dual SIOCs, the Server SIOC Connectivity field displays Single Server Dual SIOC.
Click Save Changes.
This configures the server for dual or single connectivity.
