I have seen that Sun has quad 10gbE adapters: http://www.sun.com/products/networking/ethernet/10gigethernet/index.xml I am not sure if FreeBSD supports that? could you please explain ANY CASE when 4*10GbE/s could be utilized. it's 5 GIGABYTES/s each direction. computer memory subsystem is rarely faster To be fair, the adaptor on the link is a dual port device (I looked with interest!), and Sun states the maximum is 16Gb/s aggregrate. A machine that is multi homed on 10G networks could use all ports. It doesn't mean it has to do 10G of traffic all the time. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
10gb network interface suggestions
Hi, I want to ask if anyone here in this list has any experience with 10gbE on FreeBSD? My questions: 1) Which 10gbE to use? I see that intel has a good support for 10gbE on FreeBSD with its own driver for FreeBSD: http://downloadcenter.intel.com/Detail_Desc.aspx?ProductID=2992DwnldID=14688lang=eng But also I am open to other brands. Especially If anyone has experience on that this matter would be very very helpful. I have seen that Sun has quad 10gbE adapters: http://www.sun.com/products/networking/ethernet/10gigethernet/index.xml I am not sure if FreeBSD supports that? 2) Do you suggest fiber or copper? 3) Which bus option to use ? As far as I see intel has both (Pci Express and PCI-X not sure if their PCI Express cards are PCI Express 2.0 for pcie2 http://en.wikipedia.org/wiki/PCI_Express shows significant performance boost) http://www.intel.com/network/connectivity/products/server_adapters.htm?iid=nc+server#s1=10%20Gigabit%20Ethernets2=alls3=all 4) Especially since I am new to 10gbE I also request if someone can suggest me 10gbE switch. There are lots switches but not sure. One of my colleague told me that enterasys is good ad 10gbE but not sure.

As far as I see intel has both (Pci Express and PCI-X not sure if their PCI Express cards are PCI Express 2.0 for pcie2 http://en.wikipedia.org/wiki/PCI_Express shows significant performance boost) anything slower than PCIe 4-lane is slower than single 10GbE port. PCI-X is AFAIK 500MB/s so you won't get much ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

There are lots switches but not sure. One of my colleague told me that enterasys is good ad 10gbE but not sure. Regards. This was useful to find something to be used at work -- the fact that every device has a speed in terms of MHz, and a bandwidth, in terms of Mbit to use. You can buy a 10gbE device, but if the bus does NOT support 10gbE, buying the device is pretty pointless you'll never reach 10gbE http://en.wikipedia.org/wiki/List_of_device_bandwidths Enjoy. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
