lobbes: Ah, warm ocean is best ocean. I could never enjoy the cool northern ocean I grew up next to, even in the summer. My extreme lack of fat insulation always led to my body becoming a flesh anchor. "Just relax, you'll float" "huh? Relax how?"

BingoBoingo: Each hot aisle has at least one on each side pulling in hot air for cooling. . ' . ' . Is an approximation of the arrangement
BingoBoingo: Given the size and ratio of coolers to cabinets there seems to be a healthy amount of excess capacity. There is more than one per aisle.
mod6: do they have one per isle?
BingoBoingo: In other halls they operate in montevideo they have the vertical room for raised floors, but in this building the vertical distance from structural concrete to more structural concrete is the limiting factor.
BingoBoingo: In this hall, as per the post and previous mentions in the logs cooling comes from the monster chillers in the aisles. More specifically these guys https://www.vertivco.com/en-us/products-catalog/thermal-management/in-row-cooling/liebert-crv-in-row-cooling-system-19-40kw/
mod6: Another, perhaps interesting set of images would be to take a pic of the front of the cabnet from off to the side a bit -- to show the perfereated tiles in the the floor (if it's done this way) ; and the same for the back.
BingoBoingo: Also next trip I am bringing a measuring tape. The hash marks go up to 20 in the middle of the cage before counting down again. I assume this means a 39 or 40 inch deep cabinet, but will measure myself to confirm.
mod6: Thank you Sir. From the box butts picture, from what i can tell, looks pretty much what I expected / standard. i.e. the 'fast'-rails that we've purchased should work ok. a few more images will help tho. thanks!
mod6: BingoBoingo: plz to request another 2 images. one with front door all the way open, as far back into the isle as can be taken. i.e. try to see if you can take a full frontal with the door open. and the same for the backside.

ben_vulpes: TomServo: i personally run machines for longevity, but i can see why mircea_popescu and BingoBoingo would want to run their lowendboxen hot and cram as much into 'em as possible.
ben_vulpes: what, they heat up, crack their pcbs, shut down. run your fans, this won't be a problem.
ben_vulpes: i ain't justifying shit, i'm saying that i'm not concerned about the health of the rack from a few hot boxes.
ben_vulpes: thereby actually improving cooling conditions
ben_vulpes: if we don't neglect it, i'd expect entrained flow in the same direction as the convective cooling flux, eg from front of rack to back
ben_vulpes: air currents within the DC might actually ruin this, but for the sake of the gedankenexperiment, let's neglect those for now
ben_vulpes: that argon between them doesn't move; the viscosity of the gas keeps it locked in place and it acts as a superior insulator to the glass.
TomServo: but the air between machines isn't moving, right? if not by convection?
ben_vulpes: heaven help us if the machine bodies actually drive a) because someone isn't cooling adequately, and if the gap is sufficiently small (as anyone with dc experience can attest) we'll probably have "stagnation" conditions, where the air is not actually circulating between the machines
ben_vulpes: the concern is convective heat transfer between servers. for that to happen there must be a) great enough gradient of heat between the machines and b) enough space between machines for air currents to get moving
ben_vulpes: since we're doing thermofluids tonight...
TomServo: ben_vulpes: not sure about any air gap, all the racks i've seen are pretty pretty tight
mod6: lol of course they do
TomServo: That was my point, I don't see it being worth the effore given cpu cheapness.. even with the VAT.
ben_vulpes: intel calls that an "unplanned restart" these days lol
mod6: sure, got maybe a bit more throughput, but the tradeoff was certainly not worth it if not, for instance, gaming.
trinque: heat's one issue, general system stability another. who's going to fiddle with BIOS voltage settings?
ben_vulpes: moreover it'd be what, mostly radiant with a bit of conductive through the air gap between servers, which can probably be approximated as stagnant and a good insulator
ben_vulpes: i know but if the convective flux is adequate there really shouldn't be that much heat conducted from machine to machine
trinque: ben_vulpes: wasn't thinking of it, just heat through the metal case
ben_vulpes: cooked, yes, but you hoover from the aisle in the front and dump into the aisle in the back. so long as everyone's dumping out the back, nobody should be sucking exhaust gases.
trinque: mircea_popescu: in re: cores, depends what you're running. most of my existing servers are many separate services doing tasks that don't block each other, whereas if running trb it's doubtful the thing benefits from even one extra core, except insofar as the rest of the OS's doings get shuffled off to it.
trinque: also given the difficulty of getting parts on site, might want to optimize for longevity, then CPU cycles
TomServo: If not full throttle, is it really worth the effort compared to throwing in another system?
mircea_popescu: eh, there's cpus that are made for overclocking. such as this one. it'll run fine for years, if kept cool.
lobbes could possibly swing the ~600. will keep eyes tuned to logs
mircea_popescu: not clear yet, intuitively there's a ~600, a ~1.5k, a ~4k and a ~9k chunk. but we see.
mircea_popescu: and in unrelated, wanker's worldview of perhaps entomological interest, http://theferrett.livejournal.com/1498823.html
mircea_popescu: well, if you're stuck with an overloaded rack for the few days till you get the other one up for instance, it's nice to know you've got a 20% afterburner you can run on.
TomServo: Seems to be begging for heat and reliability issues when the goal should be reliability.
TomServo: I think you're on the right track not paying the price premium on the latest and greatest and eating the power.
a111: Logged on 2018-02-06 11:09 mircea_popescu: take something like, i dunno, epyc-7351 say. costs 7x, has 4x the cores, 4.5x the ram speed, 4.5x the l2/3 cache and 50% the power. basically i'm getting less than twice as much processor per watt, if i pay 7x the money. meh.
mircea_popescu: TomServo ok, but i'm more interested in... do you have some way to discern whether more cores or more clock speed are more valuable ?
a111: Logged on 2018-02-06 13:21 mircea_popescu: BingoBoingo : the logic is, ima want 5 of the dozen ; the rest could each at least in principle support 100 "shared" sorta sites each, at $20 a month or whatever you end up charging. that's, if you manage to fill up the lot, $14`000 per month in revenue.
mircea_popescu: to my (admittedly aloof) reasoning, even if filled with 20 of these, the rack would have plenty of swim space on the sides, and should at least theoretically be ok. i dunno, i guess we find out.
TomServo: Ah, then I misunderstood.
mircea_popescu: as to the vertical exhaust, it was more of a "do you have it" curio than anything.
mircea_popescu: (for the confused : microATX, introduced cca 1996, is 244x244 mm ; same witdh but shorter than the plain ATX ; meanwhile mini-ITX is 170x170, whereas mini-ATX is 150x150 mm, so even smaller.)
