많은 PowerEdge를 구매하시는 분들이,
Dell에 기본적으로 11Gb OnBoard NIC가 있슴에도 불구하고
Broadcom NetXtreme II 5709 듀얼 포트 1GbE NIC를 13만원 정도 들여서 추가장착을 하시더라구요.
Broadcom NetXtreme II 5709 듀얼 포트 1GbE NIC를 구매해서 장착하시는 이유가 뭐죠???
OnBoard NIC 보다 좋은 점이 어떤 것이 있는거죠???

Virtualization - you can configure up to 4 virtual machines on the server and assign each virtual machine its own dedicated gigabit network connection.
Multiple networks - if your server is an intermediary between multiple networks, you would need a separate NIC for each.
Teaming - you can "team" multiple NIC's together to increase total bandwidth or provide failover/fault tolerance of a network connection; for failover, it is wise to have an add-in card together with the onboard in case one or the other fails. Your network hardware (i.e. your switch) must support this.
Some simply like to have an extra NIC for ease of troubleshooting network issues and/or fast fix for malfunctioning/failing onboard NIC.
