Why each option
When a Cisco UCS chassis with two IOMs is discovered using a fabric port channel policy, Cisco UCS Manager creates two separate fabric port channels.
In Cisco UCS, when a chassis with two IOMs (Fabric Extenders) is discovered and a fabric port channel policy is applied, UCS Manager creates two distinct fabric port channels. Each port channel connects one IOM to its respective Fabric Interconnect, ensuring redundant and high-bandwidth connectivity.
A single fabric port channel would aggregate links from both IOMs, which is not the architectural design for connecting two IOMs to two Fabric Interconnects.
Chassis discovery and port channel policies are designed for automated configuration, and the resulting port channel should be active unless there are specific configuration errors.
Configuring each uplink as a discrete link contradicts the premise that the chassis discovery policy creates a fabric port channel.
