Simple question, all my computers now have SSDs and transfers are maxing at like 130MB/s on my network which is about right for gigabit networks. Is it even possible to get faster bandwidth than this without breaking the bank? I have heard of NIC bonding but don't know how/what/whatever to get that working. Any help is appreciated.

http://en.wikipedia.org/wiki/10-gigabit_Ethernet Newegg has decent enough 10gige NICs for like $400, so guess it depends on whether it's worth it to you? That seems way more useful/less of a headache than bonding and poo poo just for double the bandwidth.

bonding won't help you with a single datastream. It's 10gbe or perhaps a few used FC HBAs off of ebay, depending on your technical prowess (which judging by the existence of this thread, is not as high as it would need to be).

You can get Infiniband stuff pretty cheap, a lot cheaper than most 10g equipment at any rate. HCAs are usually under $50 on ebay depending on how fast you want it.

The easiest thing for you would definitely be 10GbE copper, but you'll have to be willing to pay for it.

10Gbe copper is gross and won't actually hit 10Gb after the cable is longer than a few meters I believe.

Except that as soon as you go SFP+ you have to either take your chances on lovely Chinese SFPs actually managing to get around the switch-makers' protections and register themselves as authentic, or pay out the rear end for the OEM SFPs. I cannot loving wait for 10Gbe copper to come down in price - I'd much rather pay a slight premium for Cat7 than hundreds or thousands of dollars PER PORT just so I can have the privilege of buying expensive fiber cable to plug things in. And I don't need SFP/fiber connections in my top of rack switch except to trunk back to the main stack anyway, so their argument that it's more flexible than RJ45 ports is loving stupid. Or of course I can use Twinax, which has the same length limitations as Cat6 (or worse, I think Cat6 will do 20-30 meters and Twinax stops after 15) and STILL has compatibility problems because Cisco/Brocade etc. don't want to let go of the sweet sweet razor blade cash for buying their proprietary modules, most likely made in the exact same factories as the knockoffs but without the special codes embedded that proclaim them "authentic". The whole business is a loving racket and should be ended post-loving haste.

Captain Foo posted:Approved optics has real good prices and I've never had a compatibility issue, though I think I've only used them for sfp not sfp+ Well the other problem is that the switch makers are always playing catchup with blocking the third parties, which means that a new release of software will inevitably render some previously-compatible third-party SFPs incompatible. Depending on how often you update your switches this may or may not be a problem, but if you have a large deployment of third-party SFPs and upgrade, suddenly that "free" switch upgrade (which these days is less and less free, at least with Cisco) just cost you a mint in new SFPs. Plus potential downtime and complete confusion if you're not aware of the issue, since if you have a mix of SFPs, SOME may stop working and others may be fine, and you'll have no idea why. And of course the companies say up front "we absolutely don't support third party SFPs because they could not work". Hey listen. I get that. The third party stuff may not be held to the same quality standards. But don't tell me that the supposed quality difference is worth literally 10 times as much. When it's clearly just gouging me is when I get pissed off and start calling it a racket. (Also, I've never heard of any real quality differences in these things in terms of packet errors or speed issues). It's the same issue as Ford or Toyota claiming you need to use their parts and only their parts, and I believe there were laws passed to prevent them from disallowing warranty service etc. Though maybe I'm misremembering. But there's certainly nothing currently to prevent switch makers from doing it, until RJ-45 becomes more prevalent in 10 GBe switches.

believe it or not, you can have 10gbase-t at home for a reasonable price. http://www.cdw.com/shop/products/NETGEAR-ProSafe-Plus-XS708E-10-Gigabit-Switch-8-ports/2947237.aspx?enkwrd=XS708E It's not cheap, but it's pretty impressive that they are able to give you 10gbase-t for $1k.

I'm more interested in the price drop when it becomes ubiquitous. Even if its PCIe capped at 2G-5G I'd be fine with that on first gen integrated stuff. Anything better than 1G and bonding.

I can't be bothered to lookup the timelines, but it certainly seems that 1000BaseT has now been ubiquitous for longer than 10- or 100-. It first started coming out on motherboards in like 2000? My laptop in 2003 certainly had it.

In my last job I bought probably more than 200 'lovely' Chinese SFP+ modules for around $40 each for SR and $60 for LR. Of those, around 3 were DOA and none of the others had any problems. All we had to do was enable 'service unsupported transceiver' on our Cisco gear, then we had full diagnostics and monitoring, it reported the wavelength in IOS, and we didn't have any problems. I have since seen the same SFPs (exact same casing) from several 'manufacturers', so I imagine they are widely rebranded.

Going off of ebay I could probably build out a 4gb fiber network for my servers and my desktop for about $150-$160. Think it would be fun or worth learning about? I could get a switch for about $80-$100 and then the cards for about $20 each. It would be kind of useful for setting up high availability virtual machines and also doing backups and stuff. Would it be worth doing for fun?

Looks like you can get bulk SFP 4gig modules at a pretty good price. If you could track down a few blank SFP NICs on the cheap this might be possible for less than a couple hundred. Dunno where to find blank SFP adapters though, they all seem to come with modules included. EDIT: I was able to find on eBay 16 4gig modules and a 8-port switch filled with 2gig modules for less than 50 bucks total. Seems like that + a couple cheapish single-port NICs would be enough. Wonder what the cable costs are. I've got a 75 meter run and a 10 meter run I'd need to do. EDIT2: After doing more reading I'm wondering if it's even possible to just plug in faster SFP modules into a switch or if the switch needs to have some type of support for that module? Are they plug-and-play? revmoo fucked around with this message at 13:47 on Jun 4, 2014 |

Most Ethernet switches don't support 4Gb GBICs (The only exception I know of is Adtran, and they're proprietary and need Adtran equipment on both sides). As far as I've seen, the Netgear 10gbe stuff is the cheapest. http://www.pcnation.com/web/details.asp?affid=808&item=QV6894&gclid=CP73wqO8qb8CFSJo7AodZUkA5Q Cat6 works for 10g up to 37/55 meters (depending on crosstalk conditions), and Cat6a can do the full 100.

You could do 10G SFP+ Direct Attach for a home network since runs are <10m, right? I've always used up to 25ft Ethernet cables for my setups. Of course you still need to pay for a switch and NICs, and I guess the cables become a non-trivial expense after a certain point, but you don't need to pay for SFP+ modules. This also lets you buy an SFP+ module if you need a longer run or compatibility with hardware that doesn't support Direct Attach. SFP+ Direct Attach gives me something of a nerdboner, it's just hilarious that we made a socket for modular transceivers, and then were like "wait, why do we need transceivers again?" and just hooked the sockets together with a cable, letting them talk to eachother directly using the protocol originally designed for the socket to talk to the transceiver.

Direct attach cables are a pain in the rear end to wall fish or do anything with that's not in a rack. Also, they're more expensive than Cat6, and they have compatibility issues over 5M (since anything over 5M typically requires active cables). HP actually makes 15M active cables now, BTW. If you asked me 2 years ago, I'd say do direct attach. Now? Just use 10G Base-T (unless you have a device that doesn't have that option). Direct attach is still worth it for 40G QSFP+, though.

adorai posted:bonding won't help you with a single datastream. In the majority case this is definitely true. If we're talking theoretical maximums then you could use more than one gigabit link with multipath TCP and get a throughput higher than 1Gbit/s. The tooling cost for this setup and the workloads it would be good for limit its usefulness to a point where buying a pair of 10Gbit/s Ethernet cards is probably cheaper.
