Question

A storage administrator is deploying an iSCSI SAN where each server has two NICs connecting to two separate physical switches, and the storage array presents its targets on two subnets. The goal is to achieve both redundancy AND active/active load distribution across both paths to the same LUN. Which host-side configuration should be implemented to meet this requirement correctly?

Accepted Answer

Configure host multipathing (MPIO) with each NIC bound to a separate VMkernel/iSCSI port on a different subnet

Answer

Configure NIC teaming (LACP) across both NICs and present a single iSCSI initiator interface to the array

Answer

Bridge both NICs into a single Layer 2 domain and rely on Spanning Tree for path failover

Answer

Use a single NIC with jumbo frames enabled and configure the array for target-side failover only
