Is there something in the pipe greater then Gig-E over CAT5?

I'm wondering whats the next standard they are working on, or have they squeezed out as much as they could get out of cat5 with Gigabit ethernet?

10G will be amazing ... I believe this should get to the desktop market in 5 yrs or so... hang tight... for now it is only available in high end $$$ cisco switches

I remember an article so far in that past I can't begin to quote it, that the wavelengths for 10g can have problems with current fiber plants that are often installed barely within spec or out of spec. Namely the bend radius not being observed.

Well, considering (some/most) building codes now require fiber run to each workstation, I wouldn't be surprised to see everything make a switch to fiber...

Only problem is you're passing the speed at which hard drives can write things so to omuch speed isn't going to make any difference when it comes to direct transfers. But I'm sure it will raise up a whole network if everything is setup with the higher speed.

that was the thought 6-10 years ago.

Its still all copper. The fiber to the desktop idea is kinda dead.

And 10G on fiber really isn't all that special. 62.5 or 50 micron multimode fiber works great (no special requirements, except for modal bandwidth) in 50-300 meter lengths.

RAM...cache....it makes a difference...

One thing many people fail to consider is that with 10G or GigE or GigE over 100Mb/s, is tha servers can process requests faster, improving overal network availability since the server can deal with multiple requests faster, such as SCSI vs. IDE...

There's already 2 gbit fibrechannel (in copper it is very similar to cat5 gigE) and they're working on 4 or 5 gbit copper fibrechannel. This could probably be adopted to make a 2, 4, or 5 gbit cat5. But seeing how Ethernet has gone from 10 mbit to 100 mbit to 1000 mbit, my guess is they'll just wait until they can do 10000 mbit / 10gigE, rather than some smaller step in the middle.

10 gig has been out for over 3 years. fiber channel is still stuggling to keep up with the network world - that's why I think it will be a dead technology in 5-6 years. It will all be over IP.

Everything will be over IP eventually, including home telephone and cell phone service.

My point is, FC has been doing 2 gbit over copper for a few years now, so there's no reason why they couldn't make a 2gigE if they wanted to. I hear that 4 or 5 gbit FC over copper is also in the works... so again, they could make 4 or 5gigE if they wanted to. But they haven't. Which is why I think the next copper step we'll see is 10gigE over copper (probably cat5e or cat6).

Storage over IP is a neat concept and I'm sure we'll see iSCSI overtake FC once 10gigE NICs become the norm. But today I think the safest bet for a new purchase is tried and true 2gbit FC. Most of the 133 MHz PCI-X and PCI-E HBAs already support dual channels, so that's already a nice 400 MB/sec connection to your FC switch / SAN.

That said, I can't wait to buy a 5-port 10gigE copper/cat5e switch from D-Link for $50.

heh, 10 gig over copper is still the push. Given that 1000 Base-T was ratified....what? 4 years ago max? I think 10 gig over copper will be common place in 6 years.
