Hardware requirements for multiple 1GB NICs



  • Looking to use a quad port 1GB NIC card on a superMicro 1.66 GHz two core superMicro MBD-X7SPA-HF-O Intel Atom D510 motherboard.

    My concern is the hardware. This is for a home network. The only high volume traffic would be gaming on xbox or streaming movies. Will the hardware be able to keep up with the NIC?



  • What is the bandwidth of your link? Checking the hardware sizing guide your CPU should be good for over 200 Mb/s. The NICs themselves then matter - are these RealTek, Intel, something else? Are they connected by PCI or PCI-Express…?

    Thanks for reply CH. I was hoping to take advantage of 1 GB connection. Looking to buy this intel quad port card: http://www.newegg.com/Product/Product.aspx?Item=N82E16833106050



  • Quoting from that hardware guide I linked to:

    501+ Mbps - server class hardware with PCI-X or PCI-e network adapters. No less than 3.0 GHz CPU.

    Your card, and PCIe interface, will handle the bandwidth, but your motherboard and processor are unlikely to.

    Thanks for hardware sizing guide. I'll keep that in favorites.



  • XBox and streaming don't need gigabit, they certainly don't need multi-gig setups. Save yourself some trouble and cash and use dot1q (802.1Q Vlan tagging) with a capable switch.



  • It's a home network and you want to run Xbox and streaming video over it? What on earth do you need gigabit NICs for unless you're going to try and make pfsense your switch too which isn't the best idea. The question you need to answer is "what is the speed of your internet connection?" That alone will determine what hardware you need and whether you really need that quad port gigabit card. That's what Cry Havok was asking, and I seriously doubt you have a 1 GB connection to the internet. Semantics here but even if you have a "1 GB" connection, a gigabit card will be the bottleneck as it is only 1 Gb which is further reason why I don't think you have an internet connection that can fully utilize a gigabit card let along a quad port card.
