Thunderbolt Networking
-
I just read the article, and what they are describing is exactly what happens in my SAN when you transfer over a ton of really tiny little files (like a 500MB folder of fonts). It slows to a crawl, and then once it powers through the Fonts folder, it zooms back up to 4-700MB/sec (all through 8Gb fibre).
I wonder if this also has to do with r/w behaviors of SSD storage, and what types of files he is transferring.

So does this mean that I should stop holding my breath, waiting for 10 Gigabit Ethernet to come standard on a Mac?

If you boys read this article, you will see the following statement towards the end of the article –
“Assuming stability and consistency will be improved, is Thunderbolt networking useful in the first place?
Obviously, outfitting Macs with Thunderbolt 10 Gigabit Ethernet adapters and hooking them up to a 10GE switch is the superior solution. With an equally superior price tag. In situations where a fast network is only needed to copy files between two computers, using a $30 or $40 Thunderbolt cable is much more convenient at a fraction of the price. I can also imagine a Mac Pro being outfitted with a 10GE adapter, and then one or two other Macs connecting to the 10GE network through a Thunderbolt connection to that Mac Pro. And if Thunderbolt networking catches on, we may even see Thunderbolt ports on NAS devices.”
SO – what does this all mean. I know exactly what this means. Someone today told Steve Bayes about NFS enabling “Add SAN Location” and all of a sudden, you can do shared storage, and his response was “why don’t you just use XSAN”. Of course, we all know the answer – because it costs TOO MUCH DAMN MONEY to configure an XSAN system. Of course, I build 10GbE shared storage systems, so this is what I want people to do – but the people that are excited about this article only want ONE THING – to be able to have a shared storage system for $40 dollars, and not have to hire anyone to do it – just plug in your $40 cable, (maybe a $100 non existant Thunderbolt hub) with your $2000 Promise Pegasus, and do everything that a $60,000 XSAN system can do. WELL YOU CANT HAVE IT. Keep holding your breath.

We talked about this several days ago on the COW in the thread regarding IP over Thunderbolt.
I think the article you quoted may have added some confusion. The article talks about the TB Bridge as anEthernet network, but he did not select Ethernet as his TB Bridge option, He enabled Thunderbolt2 in the sample screenshot so I think he was running IP over Thunderbolt, not Ethernet. Ethernet is an option he could have selected.
Or have I got this all wrong and the article is clear with the only confusion being in my head.

I can’t really see the world swapping millions of miles of ethernet and 23 years of development for some new thing that’s largely Apple-centric and as yet hardly developed at all. Its a bit like the thread a while back that speculated that the new MacPro would make a good server for datacentres. Not a chance in a million years, and those who thought it might work obviously have never seen the pics of such places or looked at the specs of the machines used there. Koolaid fuelled idiocy. I think that maybe Thunderbolt will be largely ignored in the big world, much like Firewire 800, apart from those companies that can see a profit in overcharging for special cables etc.

I don’t anyone was suggesting this would be useful for the “world”
[Bernard Newnham] “Koolaid fuelled idiocy.”
Enough with the Koolaid, this is being discussed as a possibly interesting development for small edit shops, no-ones suggesting it will change the world

Enough with the Koolaid, this is being discussed as a possibly interesting development for small edit shops,”Even with small edit shops, there are currently only three lengths of Thunderbolt cables for the foreseeable future (and none of those is over 3M/6.6ft), so it seems pretty limited by that.

“Didn’t know that! I would assume this will change but I’d imagine the cost will be very high.
