A customer has purchased two dual-port Fibre Channel and two dual-port Ethernet cards. Which configuration will provide the greatest amount of redundancy for two client partitions?

Question

Accepted Answer

D. Create a dual VIO server environment, each with one Ethernet and fibre card. Make sure each card A dual VIO server environment assigns each VIO server its own dedicated Ethernet and Fibre Channel adapter, so if one VIO server fails entirely, the other continues servicing client partitions without interruption. This architecture removes the single point of failure at the hypervisor I/O layer and is the recommended IBM PowerVM high-availability pattern for client logical partitions.

Answer

A. Assign each client one fibre and Ethernet card. Make sure they are cabled to a different network Assigning physical cards directly to each client bypasses VIO virtualization and provides no protection against adapter-level failure within a shared I/O path.

Answer

B. Assign each client one port on each of the fibre and Ethernet cards. Cable each to a different network Splitting ports across clients still leaves each client dependent on a single shared physical card, providing link-level redundancy but not full VIO server failover.

Answer

C. Assign all resources to a VIO server. Create an Etherchannel on the network adapters that connect EtherChannel improves network link redundancy and throughput but does not protect against Fibre Channel path failure or a complete VIO server outage.
