What nobody wired their abode with fiber ?
Am i the only one here I ran a bunch of fiber from the telco rack
What's in the telco rack? This is in your house? What's on it?
Demarc and lightning suppressors for T1, 2xISDN BRI, DSL, cable, satellite, a USR Courier V.Everything for backup paging, a USR Courier I-Modem for 56K-capable OOB dialin to the network, which will have some people today scratching their heads, but made sense back in 2000. I killed our ISDN service earlier this year because VoIP has become a better choice for voice and because I hadn't been stranded in any hotels without Internet or 3G coverage in like half a decade; the OOB dial-in simply wasn't being used any more, and I deemed it obsolete. Technically that's all on the plywood and not on the rack itself. The rack is where all the house ethernet terminates, and also holds switches for the house ethernet, an Adtran 550 for format conversion (BRI/POTS/etc -> T1) to our Asterisk environment, the Asterisk box that has a T1 card to handle that, some KVM-over-IP gear in the DMZ, two managed power strips, two rack ATS's, and three APC 1400's (one of which backs up the two primary units). Most of my stuff runs between moderately old to seriously ancient, because a lot of it is gear that's been recycled out of data center production use.
to the server rack to reduce the risk of damage to expensive servers ... it's likely to be meaningless but it is just a little extra precaution. The server rack is at least a little bit isolated from everything else.
Servers have fiber cards? Or is it fiber between switches only?
http://www.sol.net/tmp/nanog/serverrack.jpg No laughing, it's in the messy phase, I'll get all ticked off in a few months and clean it all up again. But that only happens every year or two. Three switches in the top of the server rack, with a 2xGE LACP trunk running in a loop through them; four multimode fibers go from there to the telco rack as part of that loop to the switches in the telco rack. Then there's fiber over to the workshop bench switch to keep that electrically isolated as well. The OOB management network also has a 10Mbps fiber between the telco rack and the server rack. So I think it never got to the point where I was using more than seven of the dozen runs. I never really originally intended to make much use of the server rack; it was meant as a place to stick rack mount gear being played with or fixed, and as a home for the house fileserver. However, as luck would have it, in 2004? 2005? I had reason to re-examime the way we were running things, and it became clear that there was an obvious split between stuff that was high-bandwidth-100%-availability and low-bandwidth-just-should-be-available, and so I closed our Milw POP and moved the high bandwidth stuff out to Ashburn, and the low bandwidth stuff here. Saved hundreds of dollars per month plus also reduced heating bills in the winter. :-) Some of that's been reduced through virtualization of course, but growth in the network always seems to kind of balance that out somewhat. ...
