Where does Cisco UCS handle Fibre Channel traffic failover?
Cisco UCS handles Fibre Channel traffic failover on the host by using multipathing software. Multipathing software, such as EMC PowerPath or multipath I/O (MPIO), monitors the health of the paths and automatically redirects traffic to a healthy path if a link or device fails. This setup ensures redundancy and high availability for storage connections.
Answer is B, the Multipath software monitors the health of paths and automatically fails over traffic to a healthy path if a link or device fails.
Answer should be C
No Answer is B. that's the correct Typically, host software—such as NIC teaming for Ethernet and EMC PowerPath or multipath I/O (MPIO) for Fibre Channel—provides failover across the two fabrics (Figure 4).
It depends. Each vHBA has a checkbox to enable failover to the other fabric. But best practice is to leave that option unchecked and have your end host do it (for example VMware Round Robin, etc). I would go B but with who knows with Cisco.
