When shopping for a datacenter...
...make sure it has redundant A/C.
Cause it'll get up to 96°F (that's 36 ° C to.. everyone else) in Phoenix. And then things start getting melty and your hardware nodes start shutting themselves down because they're hot and stuff. Self-preservation and all, y'know.
And when you try to turn stuff back on, well, you're going to have to wait:
New datacenter has A/C. And then it has redundant A/C. And then it has ANOTHER redundant A/C.
I can't wait til May when we move.

Could of just pressed "Esc" :P
We tried that on a different node, it managed about 5 lines of kernel output and committed suicide...
You also shouldn't use CPU's that sit at 100W <_<

Indeed, we just bought a whole pile of new Supermicro systems over Easter weekend that will be used to replace our old hotness when we move.
so not sexy
Sometimes you must clean the dust, and change the thermal compound... lol
Won't do much if the ambient temperature is too high :P
From 20 (for example) to 36 isn't too much difference.
I think cooling is sufficient in the UK, You can hear the ventilation when Just outside.
Only an 80% increase
Netburst LOL.
I also like how wordy the warning is. "Temperature violation detected" instead of "System Overheat"...
Yes, for US is the hell in the earth, but +16 for a chip at... let's say 60, is 76, so isn't too much
Your nodes have dual 3.0Ghz xeons with 3GB of ram? That is from what, 2000? wow!
And in a DC without redundant AC?
damn, my 2010 server is 1 xeon
rolleyes
It's used for uptime monitoring, cacti, and munin. And that's about it. It's getting replaced with a dual-core 1.8ghz Atom with 2gb of ram and an SSD, shocking!
So a 512mb VPS could easily replace it, and I bet IPXcore would make an excellent choice for your VPS needs.
What he said..
It also generates reports, runs an X server for ilo/DRAC, controls the serial console connections for the switch & router, and contains the NIC that connects to the "backdoor" port for when Bad Things happen such as DDoS.
You guys are tough :P
Anyway, IPXcore would indeed make an excellent choice for my (and anyone else's) needs.
The majority of "DC friendly" rackmount kit works fine with an inlet temperature of 40dec C, with some able to function just fine @ 60degC - thats the temperatire range in a lot of "shipping container" setups.
It was 96f outside the data center and MUCH HOTTER INSIDE. By the time I got there It felt like 110f .
The best data centers run 2N+1 which means they have 2x the number of units that are required to run the datacenter. Most places claim N+1 or +2 which means they have spares.
But I'd point out 2N+1 can be costly to build, 100 million for 6000 sqft. It's about 25% cheaper on expanding because the power system is basically a substation so it can expand with space cheaper than building LV switch gear for each addition and bringing in new lines.
Walmart is building a new datacenter right up the street and they're sinking 100 million into 20,000 sqft usable, but the power company has a substation about 1000 feet away so there was no need for them to build in HV switch gear. What's funny is the city hailed it as a jobs success when it might employ 50 people for less than 75k each.
Now if WalMart broke into the LEB market...
PhoenixNAP/SecuredServers has a really large facility there. Additionally Singlehop is building a new Phoenix DC and they're already taking preorders for there new Phoenix location launching in May.
Challenge Accepted <_<
