Heatwave shmeatwave: Brit IT departments cool their racks – explicit pics

Stoneshop
Flame

Re: I've done this too

Over 20 years ago, so no smartphone pics.

Aircon popped in computer room. Getting toasty rapidly.

Close to 35, in my case: I'm in the computer room for some reason when I hear the dull roar soundscape changing. After a couple of seconds it dawns on me that it's the aircon rumble that's absent now. Which means that there's now close to 100kW going in every second that's not taken out, which is clearly suboptimal for the continued operation of the equipment present. I sprint out the door and into the sysadmin pen, and alert those present. Half get assigned to raiding the offices and confiscating any fan they see, the others shut down and switch off all the systems and storage not deemed absolutely essential. It's the one time I've seen a thermograph move, climbing 10 degrees in as many minutes.

We lost maybe three RA81 HDAs and one logic board out of well over a hundred, and one memory board from one of the systems.

Re: Ceiling or floor?

Those 10U wall racks aren't usually that big a problem regarding heat, though. Half the height is patch panels, one or two cable management panels, three or four switches at maybe 100W each. A decent rack design can deal with that.

Mine (10U) takes 130W max, and internally it's about 5 degrees above ambient

Additional cooling

One contract I had was with a branch of the Dutch Ministry of Agriculture, housed in (then) 40-year old barracks. Single story, low tarpaper roof, and even on just moderately sunny days the offices were already uncomfortably toasty. Cooling to the computer room was half-knackered, as one of the two units had a pinhole leak that apparently wasn't fixable, which had caused them to use up their freon-based coolant quota already. This lack of cooling caused serious swings in the computer room temperature, with a resultant well-higher than average component failure rate.

Their method of trying to keep the temperature within acceptable values was by installing garden sprinklers underneath the heat exchangers, and turning them on when temps in the computer room hit 25 degrees. Time to turn the tap off was often well into the evening, requiring one of the sysadmins to clock several hours of overtime. On really warm days boosting the cooling capacity like this was insufficient, and relief had to be brought by opening the back door and pointing half a dozen floor-standing fans at it.

(My suggestion to dump a few buckets of white paint on the roof, or tack a couple of rolls of alu-coated foil over it was dismissed, as 'this is just a temporary building'. It had been temporary since the mid-1950's, and it continued to be temporary for at least five more years after I left)

One night

on call-out, I was woken with the request to go fix an 11/730 with a broken power supply. "Where?" "New-$Placename". Now, $Placename was in my region, so my initial reaction was "OK, but are there any sites there?" "Oh yes, it's the regional ATC for light airplanes." "Hmm, is that really in $Placename?" (I would surely have heard about it). "No, NEW-$Placename. It's near $City".($City was in my region too, so New-$Placename probably was, as well. Never been to that site, though, but that was something that happened occasionally). "Present your passport and your badge at the gate, they know to expect a DEC FS guy"."Oh?" "Yes, it's part of the military base there". "Ah, OK, right. I'll be off now."

So, in my car, past $City, to the site. Gate guards let me in, no problem. "Drive on for some 200 meters, there's a building on the right, the sysadmin will be at the door". "OK, thanks". It's 02:00 or so, pitch dark.

I find the building, park, get shown in, down a lot of stairs, and past several blast doors. Deep in some hardened room there's the 730. The replacement PSU arrives, I extract the broken one, fit the new one, test and that was that. The sysadmin takes me back up all those stairs and out the door, to my car. It's now 05:30, and in the first morning light I see the building has a couple of manned machine gun nests around it. Which was, eh, rather stunning as a couple of hours back I had walked past one quite closely without noticing.

And to top it off that site was actually the responsibility of another region office, but oh well.

Re: Fgs

There is not much point in having a nuclear arsenal if we can only aim it when the yanks say its ok.

With nuclear stuff I doubt that it would matter much if one was a couple of miles off, and as it would probably trigger MAD (from more than two adversaries, as it is now) there's not that much need for extreme precision anyway. The US and USSR managed fine (for particular values of 'fine') without GPS precision for decades that way.

Re: Lets...

If one wants to find an organisational failing, it might be in the area of psychology - i.e not putting safeguards in place to ensure the human driver is fully engaged with the job in hand. Perhaps requiring then to give a running commentary on the road situation, as is done in training for advanced driving licences (police drivers etc).

In Japan train drivers are required to acknowledge all signals they pass by pointing at them; this is being recorded and reviewed. And yes, this is on top of Automatic Train Control, which would slow or halt the train anyway if the driver ignored the signal.

The story is clearly dealing with, er, legacy issues if not actually happening several decades ago, given that custom date format which is something you decide to use if you're strapped for space Maybe the environment has been upgraded and space is not the issue it was, but the date format, and probably oodles of other cruft, is still there. And the environment may well still act as if it's sequential access, like it was when the first line of code was punched.

What is The Standard Date Format?

Way back, when harddisks were Fscking Expensive, I inherited a record[0] catalog database for a library, written in Turbo Pascal. To save space on its very minimal 20MB harddisk, dates were coded as 5 bits day, 4 bits month, and 7 bits year counting from 1900, stored in a 16-bit word. That wasn't too bad, since the only date info used at that point were the date of purchase and maybe a date of retirement of the physical item. However, soon after I took over maintenance we decided to also use the database for recording transactions as well. For this a larger PC was acquired for the princely sum of a tick over Dfl.10000, with a 80MB disk, so space became less of a issue. As the database layout had to change anyway, I decided to store dates as Julian making it a no-brainer to calculate date differences (which one could consider somewhat crucial for a library).
