Google's efficiency claims are completely unsurprising and do not represent any sort of achievement. Yet they tout it as being due to how awesome they are.
They wired a 12v battery to a PSU. You can see it in the pic. It's nothing special, and it still relies on the power supply to work. Their pictured server does not even have redundant power supplies.
And how much will it cost you to "match the power" of 10,000 "single quad core intel/amd cpu" ?
Obviously mainframes are expensive. They do a hell of a lot more than a normal server though.
In general, mainframes are built for reliability, redundancy, hot-swapability (of more than just hard drives!), and I/O throughput, not CPU power.
"Just to set things in perspective: I am pretty sure, that google have more cpu power, more ram, more hd space and more aggregate io, then all mainframes in USA combined."
Just to put things in perspective: You are completely retarded.
There is no possible way their solution is cheaper than a real mainframe (created for the task) when all costs are considered.
Nor is there any possible way their solution is more reliable, or more "green".
Didn't we all learn about how Google buys the cheapest, crappiest hard drives it can and just RAIDs them and tosses them out when they break?
This is the same thing they're doing here with "commodity" hardware. They buy the cheapest, oldest, used shit that runs and wire it all together.
The real issue here is not the numbers, but Google's desire to be completely independent from other vendors. It's why they "build" their own storage arrays and switches.
If they can get some PR about how they're so cool and green while they're at it, they'll do so, despite it being bullshit.
Just look at the pictured server:
Dual socket Gigabyte board (GA-9IVDP) (fine) with electrolytic caps (not fine, NOT server-grade). Xeon Noconas, I think. Only 5 years old. Aluminum heatsinks. DDR2 400. Trash (Magnatek) power supply. Hitachi Deathstars. A 12v battery. I never knew DC was more efficient than AC! WOW GOOGLE IS SO COOL!
A good mainframe would last decades. Google's frankenframe (lets call it what it is) must be sloughing off parts like skin cells from a Texan with eczema.
You are a moron who does not understand the phrase "currently existing".
I will not provide you with dozens of articles over the past years detailing trends for the increasing need for coders of legacy languages, such as FORTRAN and COBAL.
Since you can not read or understand anything I write, I will no longer respond to you.
Using just a-z (no numbers, symbols, punctuation, whitespace, or capitalization), the number of different combinations of 12 characters is 95,428,956,661,682,176.
It would take over 3 years, spidering at a constant rate of 1 billion links per second, to traverse that space.
Limiting copyright to just twitters would mean a 140 character space, with about 69 standard characters characters. ([A-Z][0-9][,.'"`~!@#$%^&*()_+=-\?/;:{}|[]])
That's a search space of about 2.7470888312671105153324051810719 * 10^257.
Then some idiot will decide to add a sanitary napkin to it, and it'll be the all that "manly" SUV getting mocked for not actually being manly all over again.
Read. The reality is there are TONS of legacy systems out there that can NOT be replaced with any currently available "solutions".
CURRENTLY AVAILABLE.
Are all those fortran programs are around simply because people are too lazy to switch over to the C/C++/web versions that were written?
(Since you won't get it, the answer is NO. Those fortran programs are around because there is NO replacement. One can be written, sure. But we have working shit already, why add cost, time, and disruption for zero gain?)
Systems can be replaced, sure, at enormous cost and effort.
"The reality is there are TONS of legacy systems out there that can NOT be replaced with any currently available "solutions"."
Note the "currently available" qualifier - it means that you'd have to hire some developers to figure out your old system, make a new one, transport all the data, and handle the transition seamlessly.
Simply NOT going to happen.
The bottom line is there is no fucking incentive for corporations to make the switch.
To get a real corporation on IPv6 will takes years of constant work, and even then you'll still have legacy systems hooked up to analog lines doing whatever it is they do on their data/fax modems.

And installing your own BIOS won't work since this shit survives flashes.
You'll have to drop your own physical chip in.
It's not about whether or not the manufacturer is malicious or incompetent, it's if a single worker in China or Taiwan has been paid by the Spamlords to infect production chips.

I was being sarcastic.
I know this full well.

Dude... UPS. If you're using the battery, you don't *have* AC.
You do know that a UPS (for the kinds of servers Google is powering) puts out AC power, right?
Oh, you didn't?

TV producer: That's miles per hour, you idiot!
You still can't fucking read you retard.
There is no currently existing replacement for a lot of fucking programs.
Developing a new system as a replacement means it is NOT a CURRENTLY EXISTING replacement.
Creating replacements costs time and money and often results in downtime or time when both systems have to be maintained simultaneously.
If you think that such systems are "hypothetical", you are an idiot.
Silverlight is not shit.
It's lame that it's required, but it's actually decent.
You hate the brand behind it, we get it.
No, that RAM you get from Apple is the SAME SHIT from the SAME factory in asia.
Uh, no.

Yup, AOL did this.
And Google is copying AOL, and being heralded as innovating, etc.
Nothing - he's just a Linux nerd who thinks he's important.
The NX bit is awesome.
ASLR is effective, but it's generally used as a way to slow down attackers after they've already figured out how to break your broken shit.
Why don't they investigate the fraud that goes on in this country?

There are tons of recent cases of memory cards, flash drives, digital photo frames, etc. shipping with malware.
