theecatman Posted April 14, 2016 Share Posted April 14, 2016 So will this be a good fit for moving lots of data between an unraid machine and a Windows 10 machine? Sent from my SM-N910V using Tapatalk Quote Link to comment
ucliker Posted April 14, 2016 Author Share Posted April 14, 2016 Yes that's exactly what I used them for. You need to enable a bunch of settings like jumbo packets etc but with caching and fast ssd's in my windows 10 pc I amazing speeds. You will find out really fast the gigabit networks get saturated very easily. Sent from my iPhone using Tapatalk Quote Link to comment
ucliker Posted April 14, 2016 Author Share Posted April 14, 2016 Linux tech tips did a few videos on YouTube about them with unraid. There's a bunch of setup tutorials online and on YouTube. But they work out of the box with Windows and unraid Sent from my iPhone using Tapatalk Quote Link to comment
theecatman Posted April 14, 2016 Share Posted April 14, 2016 Yes I believe I saw one of those videos, Im trying to wrap my brain around windows configuring and also unraid as far as gigabit ethernet for the web and home network vs the 10 gigabit connection does it set up a private Network?

ucliker Posted April 14, 2016 Author Share Posted April 14, 2016 Yeah you leave the gigabit as it is now. Then once the 10gig is installed you give it an IP address of like 192.168.5.1 and the other card 192.168.5.2 subnet stays the same 255.255.255.0 you leave everything else blank because that connection will not need the Internet. Then in Windows go to network connections and sharing again pull up the network adapters then hit alt and the top hidden menu bar will show. Then you give the 10gig network priority over the gigabit and your set. Also you want to enable jumbo packets on both cards. It's really not difficult I watched a video and did it in 5 mins. I tested it with an nvme m.2 ssd and 2 Samsung evos in raid 0 and maxed out the connection. If you don't have that many ssd's then make a temp RAM disk. All in all your speeds will be way faster depending on file types. I transferred 1.6TB in a little over an hour Sent from my iPhone using Tapatalk Quote Link to comment
ucliker Posted April 14, 2016 Author Share Posted April 14, 2016 Well just about maxed out but if you test RAM disk to ram disk you will Mac it out Sent from my iPhone using Tapatalk Quote Link to comment
nightanole Posted April 14, 2016 Share Posted April 14, 2016 HOW long is the cable? Quote Link to comment
ucliker Posted April 14, 2016 Author Share Posted April 14, 2016 3M/10ft each there's 2 Sent from my iPhone using Tapatalk Quote Link to comment
ucliker Posted April 14, 2016 Author Share Posted April 14, 2016 You can get longer ones but I think the longest is 30ft but I my be wrong. These are sfp+ copper not fiber. Same. Speeds way cheaper Sent from my iPhone using Tapatalk Quote Link to comment
theecatman Posted April 14, 2016 Share Posted April 14, 2016 Wow that's impressive, I won't be transferring too SSD but to 6gbs Satas, and it should still be hopefully double the 110mbs or more than I am getting now? I believe you don't have to use a 10gbe cable I thought i read somewhere a good Cat5e or Cat6e works between the cards?, I have to zoom in better but are the connectors on the cards SAS or ethernet ?

BMTN Posted April 15, 2016 Share Posted April 15, 2016 Strange the link you posted is for only 1 card with no cables. Can you triple check, I can't seem to find two cards with two cables for $75.00. Quote Link to comment

StevenD Posted April 15, 2016 Share Posted April 15, 2016 This is the "For Sale" section of the forum. I believe the OP is trying to sell two cards and a cable. The link to Amazon was so you can see the specs on the card. Quote Link to comment
ucliker Posted April 15, 2016 Author Share Posted April 15, 2016 Guys I am selling the 2 cards and 2 cables. Like theecatman said I posted that link as a reference Sent from my iPhone using Tapatalk Quote Link to comment
Drider Posted April 15, 2016 Share Posted April 15, 2016 DIBS! Two questions first: Do you have the Half Height Brackets? Is it $75.00 for both Cards & the Cables? Thanks, and awaiting to pay pending answers! EDIT: Sent PM as well. Quote Link to comment
ucliker Posted April 15, 2016 Author Share Posted April 15, 2016 Yes $75.00 is the price for everything. No unfortunately I do not have the low profile brackets. You can find them occasionally on eBay/ If I have a card I really want to use I modify the bracket or find a video card bracket and modify that. Quote Link to comment
Drider Posted April 16, 2016 Share Posted April 16, 2016 I've been trying to send you PM's but I'm not sure they're going through. I'll take them, if you're not getting my PM's you can Email me at a burn email account I set up: Thanks. EDIT: Removed Burn E-mail. Quote Link to comment

Akio Posted May 6, 2016 Share Posted May 6, 2016 just a quick one: here's the step-by-step guide how to find/check/update your firmware for the Mellanox cards. https://blog.workinghardinit.work/2013/10/07/upgrading-firmware-of-mellanox-roce-cards-for-final-windows-server-2012-rdma-testing/ and the offical firmware page for mellanox http://www.mellanox.com/page/firmware_table_ConnectX2EN really be scratching my head over these cards not showing up in unraid, so just flashed my card from 2.9.1000 -> 2.9.1200 hope it makes a difference but i doubt it. any guidence of them for unraid install? in short commands were mst status flint -d /dev/mst/mt26448_pci_cr0 query flint -d /dev/mst/mt26448_pci_cr0 -i C:/fw-ConnectX2-rel-2_9_1200-MNPA19_A1-A3-FlexBoot-3.3.400.bin burn Quote Link to comment
ucliker Posted May 6, 2016 Author Share Posted May 6, 2016 what system are you running? I have never had to do anything to get my mellanox cards to work in unRAID. I had to jump through hoops to get them to work in FeeNAS. So you flashed the firmware which means they are showing up in the bios etc. But they are not showing up as network cards in freenas??

Akio Posted May 6, 2016 Share Posted May 6, 2016 sorry i should had more depth to the previous post. running win10 pro64 on my gaming rig. cards were seen and able to config them easily as an extra NIC in windows. i put them to a different subnet just for upload to my server. i was able to update them both in windows 10 via the command prompt as administrator. they arent being seen in my freenas server (micro-x11ssh) my main storage for media. so i cant help there and given up trying ot get them to work. Apparently freebsd10+ has them working so i assume freenas10 will..... but ths is unraid forums ^^ naughty naughty. i havent tested unraid yet i need to dig up the cli commands again. (had my headache with switching different OS's in the past 2 days. if unraid sees them via CLI i will be a step further. having 2nd thoughts about using unraid my main storage nas atm, simply because 11hrs to do a parity check means this server isnt gonna be switched off much. (currently running on the asrock dual e5-2670 ive recently finished- will be posting update on that soon as i can tomorrow) also have a 5m cisco DAC passive sfp+ cable in place ready. spare 250gb sam evo 840 ready for unraid testing. and a 850 model in my gaming rig too. hoping to hit some good speeds Quote Link to comment
