Well, our new supermicro server
We've been using IBM 10G switches (8124 and 8264) sfp varieties back when they
were Blade Networks. Very good performance, cost, and support. The use of
DACs/Twinax in our datacenters made our 10G overhaul budget work.
Sorry, that is IBM G8264T. G8316 is the 16x40G version.

Also, IBM G8364 (uses Broadcom Trident merchant silicon).
I believe the Force10 S4810 (also Broadcom Trident) is only SFP+?
Intel will force 10GBASE-T on all of us since they can make it backwards
compatible with 1000BASE-T. I think this will make the technology take off
over the next year or so

Well, our new supermicro servers come with 10Gbase-T standard on
the motherboard.

that with most environments, DAC is a cheaper
and provides better latency for your storage traffic.

Gotcha. With SFP+ I t
Gotcha. With SFP+ I think the only nod to backward compatibility would
be 1gbit RJ-45 SFPs, which can get a little spendy in large numbers
(although so can DACs).
As for distance, I admit I haven't encountered any DACs longer than 15
meters (~49 feet) -- not that I'm positive they don't exist.
Mostly backwards compatibility; simplicity. We're planning for some
super-high-density virtualization/storage projects mixed in with lower
bandwidth gear, and sticking to one type of cable for everything would be
convenient. I thought DAC had some distance limitations as well.
This is all speculat

Check out the Force 10 S4810 switch.
