I'm looking to pickup 3 identical NICs and use 2 in Win XP and eventually Vista boxes, and one on my NAS (unRAID) in linux. My current setup involves a Cable Modem into my WRT150N router running DD-WRT, and then Cat 6 running out to a Gig-E switch (Netgear GS108 v2) which connects via Cat 6 to the 3 PCs. The router also connects directly to a vonage box, PAP2 I think. Now, the GS108 switch supports Jumbo Frames with a 9000 MTU AFAIK. This is a list of NICs known to work well with the unRAID software: # Intel PRO/1000 Gigabit Ethernet (At least one report of this being broken) # Marvell Yukon Gigabit Ethernet # Netgear GA311 Gigabit Ethernet # Realtek Gbit - RTL8169S-32 chip # D-Link DGE-528T Gigabit Ethernet I was leaning towars the Netgear GA311NA, because I like netgear products and I assumed they would work well together easily. However, I can't find anything on netgear's website or newegg or ncix etc that says it supports Jumbo Frames. This really is a must, as I'm serving large video files and copying stuff around a lot (4.5GB - 15GB files) I want to get the best performance out of my network so that I'm not swearing at it (as I am right now, it is too slow.) So, does the GA311 support Jumbo Frames with an MTU of 9000? If so, is it a decent NIC? If not what is my best choice? Thanks!
