A network administrator must create a redundant vHBA for the mission-critical virtual machines (VMs) installed on a Cisco UCS Fabric Interconnect blade server. The VMs access multiple datastores using

Attaching VSAN55 to vHBA1 and VSAN95 to vHBA2 creates a redundant configuration by isolating traffic for each VSAN onto separate virtual paths. This design ensures that if one vHBA, its associated uplink, or its path fails, the virtual machines can still access their datastores through the alternate vHBA and VSAN path, maintaining critical connectivity and meeting the redundancy requirement.

Assigning both VSAN55 and VSAN95 to both vHBA1 and vHBA2 would not provide true path separation or redundancy, as both VSANs would still be dependent on both vHBAs, potentially leading to a single point of failure if one vHBA path experiences an issue affecting both VSANs.

Enabling failover for a vHBA with both VSANs enabled implies failover within that vHBA's underlying path, but it does not create distinct, isolated redundant paths across multiple vHBAs as required for robust VSAN redundancy.

Configuring load-balancing for vHBAs with VSAN55 and VSAN95 attached is a performance-related setting that distributes I/O, but it does not inherently guarantee redundancy or continuous datastore accessibility if an uplink goes offline without proper, distinct VSAN-to-vHBA mapping.
