Wow really? That's the best examples of datacenters you can find? Not a single mention of PUE at all. Lots of fancy talk and equipment but no real numbers.
No, those are the first few examples I could quickly find as examples of modern data centers being designed specifically utilizing a raised floor environment. Bear in mind that I was responding to an individual who seemed to be under the delusion that having a raised floor environment somehow relegated a data center to a "less efficient" status, and I was using recent examples to illustrate his error.
You're correct that the lower the PUE for a data center, the more "throughput" (for lack of a better term) one gets for the energy being consumed. That said (and admitting that I am a fan of Google and their innovations in the field), I, like many others, am quite suspicious of their reported 1.22 PUE. I have yet to find any actual data to illustrate and corroborate how they have calculated this. If they are able to maintain that type of PUE in each fully loaded data center, that's pretty impressive. I realize that they've reported that they're able to do that, but all the stories that I've read seem to report merely that they've achieved this, and no "proof" to back it up. I suspect that we're seeing average or weighted average numbers which are incorporating some less than fully loaded facilities, which is dragging the average for the others down.
I'm definitely not arguing with you here, and I agree with all the supplemental points you added. But, in the interest of clarifying my points:
Power quality: never seen a big datacenter without a Liebert, or at least UPS in every rack. Power does not have the be contitioned except between the UPS and the machines/devices. A whole data center power conditioner is often more efficient, but unnecessary for the little guys. either way - check.
I would argue that incoming Power Quality from utility is still a key factor worth looking into. While it's true that your UPS(s) are going to correct any power quality problems, this also means that your UPS(s) have to work harder to correct the problem(s), and particularly in the case of low Power Factor, you will get less actual power available (as you will begin to encounter current limitations on the "line" side of your UPS(s) before you've reached your designed capacity on the load side.
Also, when I refer to Power Quality, I'm also referring to the frequency of power outages, spikes, and brown outs on any of your utility feeds. This will be a good indication of how much your UPS is being hit, and how much risk your equipment is potentially being exposed to. In the case of a conventional UPS with batteries, when there are frequent brown outs or spikes, it is often advisable to put a Flywheel UPS in series before the Standard UPS to absorb the small "hits" in order to extend the life of your batteries.
- Fire suppression is usually part of your building codes, and a given, as is the routine checks (at least anually) by law.
I would agree, except that there are tests that are not always required by law that should be performed. In the case of Pre-Action Sprinklers, MIC Testing is something that should absolutely be looked at. Also, in the case of any Gas Suppression Systems (i.e. FM-200), routine checks for any potential leaks could prevent a very, very expensive discharge.
While that's true, it's not really too much of an issue. The really, really heavy equipment (CRAC Units, PDUs, RDCs, etc) typically have their own stands, which are placed directly on the concrete slab below the raised floor. The advantages in flexibility with regard to airflow and cable management that exist with a raised floor environment are numerous.
Mind you, I'm not suggesting that one cannot have a successful, efficient data center without a raised floor, I am merely responding to an earlier poster who implied that non-raised floor data centers were somehow more efficient, which I maintain, is incorrect.
24" is good, 36" is better. I once had a place with 8'0".
Newer datacenters don't have raised floors because it is more energy efficient to have concrete floors.
Hogwash.
Cooling Capacity" -- what's good and what is bad? How is this measured?
Capacity is measured in BTUs, or specifically tons (12,000 BTUs to a ton). What's most important is the relationship between BTUs and KW consumptions. In a nutshell, how much heat can you remove from the building vs how much are you putting in?
Beyond the simpler questions of physical access control, connectivity, and power redundancy/capacity and SLA review
Well first of all, I don't know that I'd write any of those things off as "simple". But some other points worth looking into would be:
Raised Floor Height Cable Management (over or under floor) Cooling Capacity and Redundancy Power Quality (not just redundancy) Age and Condition of Electrical Hardware (ATSs, STSs, UPSs, Generators) Outage/Uptime History Fire Suppression System and Smoke Detection System Maintenance records Maintenance records Maintenance records
Agreed. I, like yourself, am an advocate of reasonable copyright laws, and think that there is a "happy medium". As an artist myself (though not my primary means of income...I do have a straight job), I tend to bristle at folks who seem to be anti-copyright with blatant disregard to the time and effort that goes into creating artistic works. So, in the event I came off as someone who thinks that there is no room at all for copyright reform, I digress and say that I believe that there should be copyright, though it should be a more fair arrangement than what we currently have.
Ah, I see. So you're in a position where you don't actually have any skin in the game. No wonder you don't care about protecting "your" work, it's not you that's going to potentially lose any revenue, it's the company you work for. Got it.
Things are a little different for the "little guy". Regardless of whether one's entire livelihood depends upon the work in question, I see no reason why it should be so frowned upon that one should resist being compelled to offer it for anyone to use at any time in any way, including for their own profit. I understand the argument for not wanting to allow people to artificially inflate the value of their product(s), but to exhort that any form of protection is equal to greed is a false comparison indeed.
Sorry. You are a minority. A corporate drone without creativity and/or life. Please, move along. Don't let the door hit you.....I do not support neither software patents (even though I hold some)
Oh come off it, you're full of it. If you don't support the idea, then perhaps you can explain why you hold the software patents at all?
You people with your condescending, borderline ecclesiastical defense of this "everything must be free" mentality are completely bereft of any rational perspective. I'd wager that your oh_so_much_more_evolved_than_the_rest_of_you attitude would change dramatically if the "software" you sell were subject to much more piracy, and if you were to find your ability to provide for yourself as a result.
Guys like you spout off on this tip that you'd "rather lose more sales than lose more freedoms" as though it were that cut and dried. All of you would sing a different tune if you lost all or most of your sales, and were suddenly trying to pay your bills.
Mod me down if you want, I don't care. I just get tired of this idea that anyone who creates anything should be demonized for wanting to protect it from being stolen and from wanting to be able to recoup some of his/her expenses associated with the creation.
you have surprisingly robust protections as a renter.
As someone who worked in the industry for years, and whose wife is still employed by a major, residential property management company, I must point out that the "protections" you allude to depend very directly on the verbiage of your lease agreement, as well as any local housing laws. For example, in the case of the North Carolina Lease Agreement:
INSPECTION OF PREMISES. Landlord and Landlord's agents shall have the right at all reasonable times during the term of this Agreement and any renewal thereof to enter the Premises for the purpose of inspecting the Premises and all buildings and improvements thereon. And for the purposes of making any repairs, additions or alterations as may be deemed appropriate by Landlord for the preservation of the Premises or the building. Landlord and its agents shall further have the right to exhibit the Premises and to display the usual "for sale", "for rent" or "vacancy" signs on the Premises at any time within forty-five (45) days before the expiration of this Lease. The right of entry shall likewise exist for the purpose of removing placards, signs, fixtures, alterations or additions, that do not conform to this Agreement or to any restrictions, rules or regulations affecting the Premises.
In a nutshell, your landlord can almost always come up with a "justifiable" (term used subjectively) reason to gain access to your premesis, one which could easily be defended in a court of law.
If I may refine your point, rather than the "off the shelf" 3M filters, for a Data Center, you'll want to get something like this, or a comparable filter with a MERV Rating of at least 13 in order to prevent and control contamination. It is generally a good idea to be using these types of filters as SOP in Data Center CRAC Units.
Jonathan G. Parker, 19, of Fort Loudoun, Pa., was arraigned Tuesday one count of felony daytime burglary.
IANAL, but can someone tell my what the difference is between felony burglary and felony daylight burglary? Are the charges somehow more/less severe based on the time of day or night?
JIMMY: We got a problem, that thing we took care of out at sea
HENRY: (surprised) Paulie was just talking about it.
JIMMY: Well, we gotta fish it out again.
HENRY: (shocked) What?
JIMMY: The guy just made a deal. They're gonna do coral reef tours there and I don't want anybody finding that stuff.
HENRY: (horrified) It's been six months.
JIMMY: It's still better than letting somebody find it.
HENRY: (nodding in agreement and concerned) If Paulie finds out, we got problems.
Speaking as someone who's spent most of his life in North Carolina, I can assure you, "y'all" is not a colloquial contraction of "you will". Rather it is a colloquial contraction of "you all". For example:
"Are y'all coming over for dinner tonight?" = "Are you all coming over for dinner tonight?"
Sounds like you have a metering problem. I would say that it'd be a problem in your favor, but I don't know how your utility provider will choose to rectify the difference once it comes to light (it would be a real bummer to get a large bill). What does your monthly bill say is the number of Kilowatt/Hours used? Do you know what rate plan you're on?
Thank you for that thoughtful, Insightful (yes, capitalized) post. This is how one ought to look at the hand one is dealt in life/death. We all need to remember that life is what you make it, and that there will always be difficulties. It is our choices that dictate how/when/if our lives progress and have a positive impact on others.
We should also all keep in mind that we do not know the circumstances of this man's death, nor do we know what plans (if any) were made in conjunction with his choosing to end his life. Sure, we can all relate to the idea of choosing a "fast" death versus a long, suffering one. We should all keep in mind, though, that in so doing, he also removed the option of spending any more positive time with his family/friends/loved ones.
btw doesn't concrete corrode copper which is the reason why it isn't placed in the slab anyways.
Not really. According to this article, copper should be fine when embedded in concrete so long as the sulfur content in the concrete additives are minimal.
Yes, it is. However, I'd offer that the solution is different than what you suggest. The simplest thing to do would be, have your employer buy you ANOTHER $1250 laptop expressly for work. Problem solved. Now you have an "air gap" between your life, and work life.
Think about memorabilia from 1992 being "opened" in a time capsule by a 17 year old today. Gosh, a VHS tape of "Unforgiven," and a tape of "November Rain" by Guns 'N Roses. This is not exciting.
I gotta say, this did make me chuckle. It does put things in perspective, doesn't it? Man, Slash is gonna be pissed.
Better might be to put in stuff that's 18 years old now. (That is, when she's seventeen, it will be from as long before when she is born as she is old). That might have at least a little bit of nostalgia value in 16 years.
I don't know if that's going to help much. Is she really going to want a copy of C&C Music Factory's "I'm gonna make you sweat" and "Robin Hood: Prince of Theives"?

Admittedly, this is just my opinion.

But please, continue to refute my statement with clear, unsupported, single-word denials. They carry so much weight in an argument.
Yeah, you're probably right. I mean, no one is putting in raised floor environments anymore. I don't know what I was thinking.
Quote all you want. I run an enterprise data center, and I can tell you that raised floor is certainly NOT dead.
you state "Raised Floor Height". What is good?
24" is good, 36" is better. I once had a place with 8'0".

Yes. In fact, some people will pay good money to be frightened.
