Gigabyte file transferring in just a few seconds what if I told you it was between two separate machines and then what if I told you we did it for less than $100 worth of used parts off eBay and less than an hour of tweaking within Windows well it's true and you could do it too I by power and MSI's new lineup of gaming laptops feature Intel's 7th generation core i7 processors check them out at the link below our Jour excuse me our journey began when I spotted a post on the Linus Tech tips for Forum where a user was showing off a local networking setup that boasted speeds three to four times higher than the one that we used in our guide to 10x in your network speed on a budget and at a lower price using secondhand Enterprise networking gear called infiniband so I sprung into action drafting an email to Jake that went something like hey this looks really cool but I'm super busy can you figure out what the junk is going on with this and he was like okay this looks pretty simple I order the cards in the post and a qsfp copper direct attached cable plug them in and it's Off to the Races right wrong the quad data rate or QDR 40 gbit infiniband cards we got off eBay were made by Q Logic a company that was acquired by Intel who doesn't provide Windows drivers and while showing these speeds on Linux would have been really cool the majority of our audience runs Windows so round two fight we began with high hopes for the MH rh2 A- xsr even though we couldn't find it on melanox website only to have them dashed by an inaccurate product listing the second one we bought is a d double data rate card and I've been informed that 20 gbit transfer speeds are so last week l i not to be dissuaded from spending my money by the first two unsuccessful attempts Jake ordered a third pair of infin band adapters melanox mhq 19B dxtrs for 25 bucks each and a 5 m or 15t qsfp copper direct attach cable for 30 bucks putting our total cost at $80 and still under $150 for a much longer link with a 45t cable running you about $90 the cards are PCI Express Gen 2 and should fit in any reasonably modern computer so install then in Windows device manager you should see melanox connect X2 IPI B adapter if they don't show up then install the wiof archive version 4.95 then update it to 5.10 for the most stable results theoretically this will update your cards to the latest firmware but if it didn't we will have a blog post on the LT Forum that outlines the detailed steps for forcing this manually as well as some other details about the process check it out below with the cards recognized we have functioning infiniband NYX but no subnet manager which assigns an ID to the Nyx and creates a routing table based off that so effectively then there's no way for them to receive or send anything since one of the most likely use cases for something like this would be a high-speed SMB or I scuzzy server and a preferred client somewhere else on the network we opted to install op SM on the test bench representing our file server again you can find the full details in the blog post we're getting close to the end now we need to assign IP addresses to our infiniband adapters but since they can't be used to communicate with the other Ethernet and Wi-Fi devices on our Network we want to put them on a separate subnet and keep our normal Ethernet plugs plugged into the motherboard so if your home network is1 21680 something then you could go with 192.168.1 something let's say 20 for our server and 21 for our game machine almost there except the new network pop up on both machines run a quick ping test to make sure they can see each other then to ensure that the higher speed link is used when transferring data between the two machines adjust their priority by changing automatic metric to some number we chose 20 for our onboard Ethernet and 10 for our infiniband and Bam you should have a 40 gigabit link though please note it'll show up as 32 gbit due to 810

versions of Windows we didn't see quite the results we were hoping for latencies were still super low which makes sense since infiniband is an Enterprise technology intended for storage area networks but we capped out at about one Gigabyte per second for our maximum bandwidth file transfer tests similar to 10 GB Ethernet so what gives well the answer is RDMA on Windows server or Linux we could expect much better perhaps a followup later let us know in the comments if you'd like to see that either way we're pleased as punch with the results because compared to 10 GB Ethernet we do lose the interoperability with other Ethernet gear but we gain the same transfer speeds as long as all we're looking for is point to point and a whole lot of money to put back into our wallets so this is an interesting one we've got today this is the tma2 modular headphone system from II it lets you create your own headphones providing a vast range of interchangeable options through their configuration at you can change the headband you can change the speaker units you can change the ear pads and even the cables although that last one is sort of more normal everything else though is like freaking
