UC Berkeley installed 3 CEVs (Controlled Environment Vaults) below ground on campus about 10-15 years ago. One of them houses one of the two main fiber penetrations to campus, including DWDM gear, patch-panels, border routers, even packetshapers (back when those were relevant in a large EDU environment), servers, WiFi portals, etc. This stuff has all been in place for at least 10 years and has worked really well, modulo the caveats below. Two of the vaults have 6-7 19" telco racks, and one (the one with the big fiber entrance) also has a 23" rack in addition to the others.
Caveats:
[ 17 pages of caveats elided ]
I realize I am wordy, but four bullet points (one of which involves apparel) != "17 pages of caveats". Nice try. The rest of the email was inline replies to Justin's points.
So, the elephant in the room at this stage of the thing is this:
Why don't you just *put this stuff in a building*, and, y'know, never demolish it?
Have you ever been involved in University space wars? Especially in a new building? The 9-layer OSI model gets pretty top-heavy when you factor that in. If anything, the caveats helped to keep others from wanting to use the space. But I will say that the general difficulty of getting equipment in and out of the CEVs generally discouraged UCB from doing more CEVs beyond the 3 originals. That _one_ caveat weighed pretty heavily. michael
