Since I'm new to this type of hardware, its not clear to me:
the "cable" referred to here is: Fiber? or CAT6? Its not clear. I would assume fiber, but again its not clear..

So most of these things are MAD expensive and I did ask, especially as the higher the speed, the higher the cost.
From a rough look, it is a bank holiday here.
Switch approx 10K Euro (2X switch, 20KEuro)
Nic's approx 800Euro (4X nics, 3K2Euro)
Cables aapprox 50Euro (8X cables, 400Euro)
Call it 24K Euro, for 2 servers, to talk together at that speed.
The big thing I'm looking at now is heat and power, and the damn thinks look low power and low heat (240W and 7W, switch/ nic), so an approx total off 200Watts...
Not bad. Probably comparable to 16Gb Fibre for cost and power. Can't find heat numbers.
10GbE is pricey and power hungry...

Wow! Thanks for the pricing, Joe.
Has anybody actually used Infiniband for connectivity to a SAN, in a Lab or Production?
Any impressions you'd care to share?

Its mostly iSCSI, SAS or Fibre on the SAN's, so in this case, if the NIC on the SAN was capable then you could use 40Gb connectivity, otherwise you will be using the max speed of the slowest NIC/ port/ cable in the chain.
Hope that makes sense.

| @Tim, the only person I've talked to about it was a person in RedmondT. His experience with Infiniband was like he'd found the greatest drug that could ever be invented. I'm having fun playing with 10 GbE in my lab and I can't imagine the speeds you can get with Infiniband + RDMA. |

Thanks for sharing, Joe and Aidan.
Was wondering if Infiniband had begun to make it's way into common usage, in the average IT organization.
But, that's not the case 
10GbE sounds pretty spectacular from where I sit - this High Performance gear is just fascinating.
