Hardware and Performance / Does NIC Selection Matter?
« on: May 15, 2022, 08:39:35 pm »
Assuming you've got a legitimate symmetrical gigabit ISP connection, is it possible to pick a NIC so bad it bottlenecks your connection?
Previously I had just used a R210 with it's built in Broadcom 5709 2 port for LAN and WAN. I realize these probably run through the DMI, so 4x PCIe 3.0 lanes so that should be fast enough.
I'm moving up to an R330 for my next build and I can't even find the built in NICs anywhere listed. I know it's another Broadcom chipset, maybe a 5720 but I only found one reference for that.
Is it better to split up the connections between two different NICs?
Should I follow a particular brand or chipset?
Would there be any benefit to using an SFP+ port to my core switch even if outbound is to be the bottleneck?
I see options sometimes like "Hardware packet offloading" are they worth using?
I currently have the following NICs laying around if one is preferable.
Intel 82571EB
Intel 82574L
Intel 82575GB
NetXen/Qlogic NX3031
Broadcom 5708
Broadcom 5709
