From: John Aldrich 
Any preference on GigE NICs? I'll need at least one low-profile for my Opitplex 
755. At least one will need to have drivers built into Fedora 17/18. :D I see 
NewEgg has Intel NICs, but those are $30+ / NIC. Are they that much better or 
are you just paying for the name? I know the TrendNet 10/100 NICs used to work 
pretty well when I was working in IT and management chose to use those.

=============================================================== From: Benjamin Stewart ------------------------------------------------------ John, are you sure that 755 doesn't have an integrated gig nic?

=============================================================== From: Stephen Kraus ------------------------------------------------------ Yeah, John: According to Dell, they have Gigabit Ethernet standard

=============================================================== From: John Aldrich ------------------------------------------------------ OK. Checked my XP box... it's got a Broadcom Gigabit NIC in it as well. Next do I determine what on-board NIC I have in my Linux box? Looking at /proc/modules, nothing jumps out at me about networking.

=============================================================== From: John Aldrich ------------------------------------------------------ It does.. Now that you mention it, it probably is GigE-capable. I doubt if the one in my Linux box is, though... so I still need at least one, maybe two (for my other Windows box.) Have to see what the NIC in my XP box will do...may only need one NIC. :D

=============================================================== From: John Aldrich ------------------------------------------------------ And the Linux box is apparently using some sort of RealTek chipset...and may be Gigabit-capable... Unfortunately I don't appear to have kept the motherboard box. :( Guess there's only one way to know for sure... Gonna have to just bite the bullet and buy a GigE switch and give it a shot. :D

=============================================================== From: Dave Brockman ------------------------------------------------------ Personally, if performance matters, I avoid anything RTL. Intel or Broadcom are my primary choices for Workstation or Server NICs. When you finish checking chipsets, etc, I ruled out all Netgear and similar class junk devices. Regards, dtb

=============================================================== From: John Aldrich ------------------------------------------------------ OK, given that it appears my on-board NIC doesn't do GigE, I'm looking online at NewEgg and found a Rosewill 10/100/1000 PCI NIC for $13. Now reading the reviews, it appears that this card uses a RealTek chipset, OTOH, it is supported under Linux. There were a couple instances of bad NICs out of the box, but for the most part, they seemed to work with no problems. Other than a general dislike of RealTek, anyone know any reason why this wouldn't be a good NIC?

=============================================================== From: Matt Keys ------------------------------------------------------ That sucks for you but the good news is Intel nics aren't that expensive. :) I've ran multiple iscsi throughput tests on generally available onboard/integrated nics and most results are bad. Go with a good brand nic, such as Intel, and you'll be g2g. Regards, Matt

=============================================================== From: John Aldrich ------------------------------------------------------ Never mind... I decided not to be a cheapskate and just ordered an Intel PCI NIC along with the GigE switch that was suggested earlier.

=============================================================== From: John Aldrich ------------------------------------------------------ Yeah... that's what I decided to do. I was tempted by the Rosewill NIC, but read some bad reviews... seems they have a bad habit of shipping DOA NICs. :(

=============================================================== From: DaWorm ------------------------------------------------------ I usually use lspci for figuring out which hardware I have. lspci | grep Ethernet 01:00.0 Ethernet controller: Atheros Communications Inc. AR8121/AR8113/AR8114 Gigabit or Fast Ethernet (rev b0) 02:00.0 Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01) Same thing with lsusb for usb devices. Jeff

=============================================================== From: John Aldrich ------------------------------------------------------ Yeah...but in this case it wasn't that easy to figure out.. at least not for me. Ethtool was a better way to figure it out. Ethtool also told me that my on-board NIC was NOT GigE compatible, so that helps too. :D

=============================================================== From: Stephen Kraus ------------------------------------------------------ What model Optiplex 755 do you have, what processor and size tower?

=============================================================== From: John Aldrich ------------------------------------------------------ Quoting Stephen Kraus : It's a desktop model. E6650??? 2.33 Ghz Core 2 Duo with 5 GB RAM on Win 7 X64.

=============================================================== From: Stephen Kraus ------------------------------------------------------ Well, you have a Gigabit Ethernet. Even if Linux isn't recognizing it as such.

=============================================================== From: John Aldrich ------------------------------------------------------ Well, you have a Gigabit Ethernet. Even if Linux isn't recognizing it as such. Oh, I knew that. No, my Linux box is one I built myself. :D It's got an Asus motherboard.

=============================================================== From: "Alex Smith (K4RNT)" ------------------------------------------------------ The major chipset manufacturers have all submitted drivers to the kernel and are usually installed by default. I believe the Broadcom NIC drivers most of the times are "bge", NVIDIA's are "nge", Intel I can't quite remember off the topic of my head, it may be "e1000g", and Realtek is "rge". I'm not 100% sure of those, the driver names I remember are what Solaris identifed them as. Good luck.
