Multi-port HP adapters are the optimum solution, providing extra ports to support the virtual infrastructure in one server slot and freeing input/output (I/O) slots in servers that require additional ports. HP multi-port NICs with Intel technology also allow IT administrators to configure redundant ports to improve throughput and reliability…
