10 Gigabit networks

Has anyone here taken the plunge in the home yet? I know I got laughed at last year when I suggested that we would start seeing 10Gb home networks over the next couple of years, but seeing as the cards can now be had for <£200 I was wondering if anyone had gone for it yet?

I'm guessing that since WHS v2 has gone raid, people are getting some pretty epic throughput on their Raid 5 arrays - must be someone looking to remove the network bottleneck?

Also... I noticed that a lot of the 'switches' available on fleabay appear to be modular - anyone have a quick reference guide on what would be needed to set up a basic card-switch-card style setup (or even card-card if that's possible with the 10Gb cards?)
 
I've been kind of tempted, got an 8 drive RAID 5 on my file server on a hardware controller, benched around 450MB/s reads, 350MB/s writes iirc.
To be honest though, I don't need it. 110MB/s does me fine for the few times i need to shift stuff around and i'm running 2Gb/s teamed nics so there's always plenty of bandwidth for other devices. I'll move to 10Gb/s when thunderbolt/light-peak add in cards come out and make it dirt cheap to do so.
 
Intel 10 Gigabit CX4 Dual Port Server Adapter - Network Adapter - 2 ports

Not too fussed that it's CX4 personally as I only have a couple of meters to travel.
 
Kind of my point.

It matters not that the actual NICs are coming down in price, a decent switch will still cost an utter fortune.

Why is 6a necessary? According to Wikipedia, Cat 6 also works with 10 Gbps, just with a reduced maximum distance (55 m).

Ah yes, Wikipedia, that fountain of knowledge that is 100% correct at all times and is certainly never updated by random people around the world. No guarantees that 6 will work with 10GBASE-T, and many many reported problems.

A good read.

Damn, just rewired the house as well! What's 6 good for then?

1000BASE-T. It was slated as having more available bandwidth available above and beyond 1000BASE-T, but at the time, no-one expected the next logical step to be 10GbE.

10gbit nics are realy used when you have multiple gigabit clients using one server at the same time. Rarely have 10gigabit point to point, maybe between a DB and a server. But not that i have come across.

Most of the enterprise networks i have seen do not even have gigabit to the clients yet. But as enterprise networks upgrade their cabling to cat6 and enable gigabit to the clients, they will have to upgrade their server nics to at least 10gbit.

This one company still had one or two of its servers on 100mbit.

So what's special about the electronics?

What's special about any enterprise level networking equipment?

It's cutting edge, it's not under huge demand at "lesser" levels, so the price asked is the price people are willing to pay for the technology.
 
If you are thinking about transferring a lot of data at a fast speed, it might be cheaper and easier to just use pci-e SSD card and physically take it out and walk over to the other pc :D Maybe even usb 3 would be an option as well.
