If you have multiple physical cards at your disposal you might as well use ports on different cards - at least that way if something dies it'll be easy to diagnose whether it was the whole box or just one NIC. As Tiernan says, assuming both cards are connected to suitably fast PCIe or PCIX interfaces, it's not going to make much difference to performance one way or t'other. (personally I'd avoid the Marvell ports if I could - I had very poor performance with Marvell chipsets a few years back) Kind regards, Chris -- This email is made from 100% recycled electrons ___ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
Re: [pfSense] Dual Port NIC ports
My PFSense machine has a single Dual Port gigabit Intel Nic and 2 Quad port nics, as well as a single port nic and an onboard nic. All, bar the dual port nic are on PCI-Express ports. The Dual port nic is a PCIX card in a PCI slot... I think once you have the bandwidth on the motherboard to support it, you should be grand. Checking Wikipedia, the slowest PCI-Express connections are 250Mbytes (2 Gigabits) per second for a 1x slot. And then multiply that by the number of Xes in the slot (the cards I have are 4x cards and are on either 4 or 8x slots. 4x card is 8Gigabits a second). Different generations give different speeds too... more details here: http://en.wikipedia.org/wiki/PCI_Express Long story short, I don't think it matters as long as you have a fast enough bus... biggest advantage is lower space requirements... biggest disadvantage I can think is if you lose one card, you lose booth ports... --Tiernan -Original Message- From: List [mailto:list-boun...@lists.pfsense.org] On Behalf Of Joe Laffey Sent: Saturday 21 February 2015 23:26 To: pfSense Support and Discussion Mailing List Subject: [pfSense] Dual Port NIC ports Hi, Is there any advantage or disadvantage to using the the two port on a dual port NIC vs. one port each on two different dual port NICs?

Re: [pfSense] Dual Port NIC ports
Is there any advantage or disadvantage to using the the two port on a dual port NIC vs. one port each on two different dual port NICs? Hopefully, the dual-port Intel Nics are pci-e, and so will be the fastest. The legacy Intel NIC could be PCI, and will be a bit faster than the Marvel nics. I use the slower nics for connecting to stuff like waps, or less critical nets. ___ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold

No, assuming they’re PCIe NICs and have a correct MSI-X implementation. Anything older than these technologies shouldn’t be going into a “new build”. at rates above 1Gbps? Yes, depending, ... but I’m not ready to discuss it. ___ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
