10Gb on budged with fiber — what should IP choose?
Hello Freebsd-net, I want to attach my DIY-NAS (FreeBSD-based) to my desktop (Windows-based) with 10Gb link. I could not afford 10Gb switch for sure. So, it will be point-to-point connection only for my desktop and not other computers in my house. Also, I could not use my current twisted pair wiring, as I need connection to router for my desktop too :) Cable ducts ion my house is overcrouded, so, I think only fiber is way to go, there is no chance to add CAT6 cable between my room and storage room with server, and copper SFP-to-SFP patchcord is out of question! So, I need cheap PCIe cards with SFP+ slots which is not very picky about modules (I'm on budget!), with good FreeBSD support and drivers for Win'10 (which is another problem with very old cards). What should I choose? There are A LOT of old 10Gb cards on eBay. Should I choose Mellanox ConnectiX-2? Chelsio-T3? Something else? Intel X520 looks as safe variant, but it is much more expensive and, as far as I know, it supports only expensive branded SFP+ modules, too. P.S. You could never stop upgrading your home NAS. -- Best regards, Lev mailto:l...@serebryakov.spb.ru ___ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
Re: 10Gb on budged with fiber — what should IP choose?
Intel is overpriced and still riding their Ethernet reputation from well over a decade ago with little to show for it. I would recommend cxgbe anything, so Chelsio T420 and up. The T520-SO-CR is within reason for demanding home office/small office users to purchase new and I've deployed over a thousand of these at work with flawless performance. T420 are a bit cheaper on i.e. US ebay if that is viable to you but not by too much. I bought a T420-BT that way for home use and have no complaints. For non-TOE use at 10g, the difference between T4 and T5 doesn't matter too much, pcie 2.0 vs 3.0. You can use DAC twinax cables to connect 10G SFP+ ports together. This will save several watts of power and heat on each side vs 10G Base-T. Sometimes DACs have interop problems, usually with switches. Optics are more forgiving, although again the switch side may have extra hoops like approved vendors. As far as a switch, I got a good deal on the beta UniFi version of https://www.ubnt.com/edgemax/edgeswitch-16-xg/ for my home network. Now that it is full price, I would recommend the EdgeMax version unless you have other UniFi gear. They are inexpensive as far as the physical connectivity versus the rest of the market but not quite cheap yet. These aren't exactly pro grade, the interop seems pretty poor in general, but that's the price you pay for the price you didn't pay :) Regards, On Sun, Jan 15, 2017 at 2:32 AM, Lev Serebryakov wrote: > Hello Freebsd-net, > > I want to attach my DIY-NAS (FreeBSD-based) to my desktop (Windows-based) > with 10Gb link.

How good is FreeBSD's mellanox support?

iSER is supported as initiator, however iSER target is missing, you then have to run a non-FreeBSD iSER target :-/ I'm not sure for SRP.

Ok I'm going to guess not then as it didn't last time i looked.

This function is used only by ipsec_getpolicybysock() to fill security policy index selector for locally generated packets (that have INPCB). The function incorrectly assumes that spidx is the same for both directions. Fix this by using new direction argument to specify correct INPCB security policy - sp_in or sp_out.

Re: 10Gb on budged with fiber — what should IP choose?
You should be able to find T420-CR or T420-BT for half that. The primary difference is that cxgbe is still a supported driver, and it's been high quality from the start unlike a lot of other vendors. You are engaging in archeology with the other cards you mentioned, and may spend way more value in time than you would in the purchase cost of two NICs :) On Sun, Jan 15, 2017 at 6:47 AM, Lev Serebryakov wrote: > Hello Kevin, > > Sunday, January 15, 2017, 1:03:16 PM, you wrote: > > > Intel is overpriced and still riding their Ethernet reputation from well > > over a decade ago with little to show for it.
