The HP NC364T is a quad Gigabit network card with a PCI Express 1.0a interface. It fits in x4, x8 and x16 PCIe slots. The card has two Intel 82571EB processors with 256 KB memory connected to each and another 1 MB non-prefetchable memory. The card shows up as two network cards with two ports each.

The HP NC364T works perfectly under GNU/Linux. It's a great buy if you can get it on the cheap from re-purposed / recycled servers.

lspci will show one card as:

03:00.0 Ethernet controller: Intel Corporation 82571EB/82571GB Gigabit Ethernet Controller (Copper) (rev 06)
03:00.1 Ethernet controller: Intel Corporation 82571EB/82571GB Gigabit Ethernet Controller (Copper) (rev 06)

These cards were originally enterprise cards and were very expensive when they were launched. It is possible to get used cards from re-cycled servers real cheap.

Technical details

Do note that even though it's one quad gigabit adapter it's two dual-gigabit adapters as far as Linux is concerned. This is why the following output shows two cards.
