Every single component shows how much it will heat up your place. Its this little number with the "W" at the end.
Why the hell you guys need two tollay different units for the same (Power) still eludes me, but i guess you just cant drop one with "british" in it...
So very, very wrong. W for Watt just shows how much power draw. What I'm interested in is BTUs of Heat output. A processor that uses 20W with 100% efficiency will put out 0 BTUs of heat, while a processor that consumes 70W with 20% efficiency (think early Pentium 4 processors) will put out roughly 1KBTU/hr at full load. Where does the line lie, and how can I measure the total output?
Well, since the compressor motor is on the outside of the server room, and is the primary consumer of energy, I'm going to say the answer is: "A small portion."
ermm... not exactly. Remember we are talking 31-year-old tech here. Compressor motor == in the main cabinet (takes up about 6 racks worth of floor space)
The only pieces not in the room are piping to/from and the radiator grid.
If you isolate the power going to your racks from that going to your cooling, can't you simply clamp an ammeter around the power cables going to your racks and assume that every watt going in turns to heat, then multiply watts by 3.4 to get btu/hr cooling?
Unfortunately, not quite that easy.
1 * 3-phase powers the Air Conditioning (how much of this is really leaking back into the room as heat?!?)
2 * 3-phase powers the UPS/Generator solution, which continually cycles batteries, changing the load on the line frequently, but is not smart enough to tell me exactly what type of draw is running through. Speaking rough numbers based on "percentage output usage", 65KW on main, ~10KW on secondary == 75KW, which translates to me needing roughly 255KBTU/hr or 21.25 tons of cooling.
26TB == ~5,000 DVD (Single Layer, 4.7GB per) or ~36,000 CD-ROM (700MB per). Are those JPL guys trying to convert to/from metric _again_ or was that just Zonk being Zonk?
thanks, but I am looking to expand (always get more than you need, unless budget constrains, which it does)
Speaking of which, I didn't engineer the room - it has been in place 21 years and I've been here all of 5, and all of the energy bills go to someone else.
The Liebert unit in question is rated 20 tons, but I suspect that age and failing parts have pushed it lower than that, and my average temp rises about.1F/month (72.2F last month)
I suspect that I could get by on 20T (120KBTU/hr), but I'd like to have room to expand, and going with a third unit pushes my price/unit down. Maybe it's time to get with my budget folks to see what project we can put on hold until my room is back up to snuff....
How about getting a realistic number for BTUs of cooling per HDD/stick of RAM/Processor? my 31 year old Liebert is dying, and the time has come to go to in-row rack-standing AC, but I don't know whether to stick to 2x10Ton or if I need to go for a 3x10 (underfloor in a small datacenter - 30 racks, 250ish nodes). I realize manufacturers have whitepapers out on how much cooling is recommended, but those numbers lie like dogs. "Typical installation: 1 processor, 1 stick of ram, 1 HDD, 1 Power supply" - typical config for my cluster is 4 processors, 8 sticks of RAM, and 2 HDDs on dual power supplies... anyone know where I could get this type of info besides Gartner or the like subscription $ervice$ (yep, they get you coming AND going)
You're missing the point here. Demographically and Topographically speaking, 87% of Americans live within a 20 mile radius of a major urban hub. I think 87% is a good number to shoot for as far as broadband access goes, but it's not going to happen out of the goodness of the hearts of the ISP. I'm also not saying that the government should be the ISP. You can twist statistics any way you wish, but the point still remains - availability of broadband access is still the lowest in America of any _DEVELOPED_ nation (sorry Patagonia), and its users already pay more per unit of bandwidth than any other. Why stack more taxes on top of that? A different user posted that they're paying $100/month for 8Mbit/sec. I'll even take that as a combined number (say, 1.5up, 6.5 down). The same service here (IF it's available to you) would range between $350-$1,200/month just for the subscription, not to mention getting the ISP to run line to you. I absolutely do think that the farmer 20 miles from nowhere in the middle of a cornfield should either pay for line run, or be happy with (abunchofwifirepeaters). It's one of many downsides to living in the middle of nowhere, but that option is not available to said farmer, and that's a sad state of affairs for residents of America.
When this country _still_ has the lowest percentage of its population on broadband of any developed nation (and its users pay more per kb/s of bandwidth than any other country's)? That'd be like paying a toll to ford a river when everyone else in the free world is using a 10-lane highway free of charge! The original bill was implemented to speed the proliferation of connectivity, and has failed miserably (compared to other country's efforts). What lessons can we learn from, let's say, the UK - where 94% of the population at least has the OPTION of broadband connectivity? Has a similar tax / tax exemption been in effect there? Seems we're only getting half of the question side of this equation, making it impossible to really come up with an answer...
Maybe if we all turned our add blockers off for a day we could crash the ad servers due to the new high load?:)
Alternatively, why don't we re-set-up those oldstyle sites that when you open the page, immediately begins !REFRESH of every available graphic served out by xrandom(ad)server.
I'll have to search for the story, but I believe someone set one up for a crooked camera company last year, and brought them to their knees under a $X0,000 bandwidth bill
IANAL, but isn't 'selective prosecution' is usually an issue in criminal courts, not civil. I can't see how it could possibly apply to civil cases because then you have to sue EVERYONE that causes you harm or else the one time that you did sue it would be thrown out as selective prosecution.
But if you can show a certain demographic of those you _could_ sue are getting away with a civil infringement, is this not the very definition of selective litigation?
I submit to you - and perhaps even to an "Ask Slashdot" (yes, I know - people seem to think this is useless at worst and circle-jerking at best) the following:
The member companies of the RIAA and their affiliates are well-known for massive litigation (see cases where discovery is done against Does 1-41, Does 1-36, etc...). When hard evidence comes up that a Record Executive's child escaped litigation by taking a stern talking-to, and the president's daughter gets off without even as much, what kind of example is being set, and should this issue be brought up in further cases (handled by NewYorkCountryLawyer, et. al.)?
Of course, a real submission would have a ton of links (cases v. Doe 1-XX, this story, the record exec's son's story, etc...)
Mod parent (not the OP, which is me) up - This is a thorough and cohesive explanation of what I was trying to cram into a single sentence in my OP. Thanks DM9290, I lack for words today it seems.
There is a common practice in law these days called "selective prosecution"...
While it would be amusing to see the Bushie twins dragged through a legal battle and would be a real "Nobody's safe" kinda PR for RIAA Member Companies, I doubt they would take the idea seriously unless those two got the tracks off Kazaa or some such shady means.
Why would anyone bother putting out security patches for an OS that nobody uses yet? Security through obscurity and all of that nonsense.
What I'd really like to know is why critical vulnerabilities in IE7 are thoroughly ignored, even though it's available to install on XP (and yes, hard as it is to believe, people are actually using it _instead_ of Firefox/Safari/Your Favorite Flavor here...)
I would think Priority 1 would be to protect it from environmental hazards - humidity, flooding, etc - With hundreds of boxes of the stuff, I would imagine you'd need a "vault" not unlike the buried '57 Belvedere recently unearthed in Tulsa, OK - http://www.buriedcar.com/ , but hopefully without the whole "3 feet of water" syndrome, leaving the already rust-prone vehicle completely worthless to anyone but a museum of oddities. Best of luck to you, keeping anything hermetically sealed off but still accessible over the course of even 5 years is a problem that NARA has been throwing millions of dollars at, without coming up with a solution that can scale up _and_ down...
I'm hoping they mean the Aeon Flux that was on MTV years ago, not that clusterfeck of a movie that came out 3 years ago... The animation of the movie was terrible
Also, why is this in Games instead of Entertainment? It's not like we'll be interacting with the content beyond the slo-mo buttons for jiggly fun
To the original submitter - I get these calls all the time. That particular code is not an area code, but a country code. 63 = Philippines , while 2 is the City code within the Philippines for Manila, it's also the city code for all of the cell phones in the country. Hope this helps!
Thanks for the advice, but trust me I've already looked into it. Here in VA, if you make more than $16k/year, you're on your own, unless you've got dependents (none thank god), and/or have one or more of a certain subset of physical disabilities. Maybe I should just take work at the migrant worker center, all my pay would be under the table and I'd end up netting more than I do now working for the federal government (who offers me a health plan at the low low price of 5% of my take-home pay, plus co-pays out the wang)
That must be nice. I make about $22,000 a year, making me inelegible for the plan you're talking about. Health care is available to the "impoverished" of America, but totally out of reach of those of us just keeping our heads above water.
How about this - we set him up like you say, with 1,277,000+ messages, all with the same text, but one contains a code for "Get out of jail free" - all others contain a code for "5 more seconds in lockup" - how's that sound?
