Google could be experimenting in all kinds of wild ways, running boards with cores or attached disks. If we assume that each server has a couple [9] Anywhere from 2 to 5 of 2 TB disks attached, we come up with close to 10 exabytes [10] As a refresher, the order is: kilo, mega, giga, tera, peta, exa, zetta, yotta. An exabyte is a million terabytes. The commercial hard disk industry ships about 8 exabytes worth of drives annually. To make things worse, given the huge number of drives they manage, Google has a hard drive die every few minutes.
Of course, that only covers storage attached to running servers. What about "cold" storage? Who knows how much data Google—or anyone else—has stored in basement archives?
Assuming they've stepped up their purchasing since then as they've expanded, this could add up to another few exabytes of tape archives. Let's assume Google has a storage capacity of 15 exabytes, or 15,,,,,, bytes. That's three times deeper than the ice sheets that covered the region during the last advance of the glaciers:. However, it's nothing compared to the ridiculous claims by some news reports about the NSA datacenter in Utah.
The NSA is building a datacenter in Utah. Later reports changed their minds, suggesting that the facility could only hold on the order of exabytes. A few headlines, rather than going with one estimate or the other, announced that the facility could hold "between an exabyte and a yottabyte" of data [17] Dailykos: Utah Data Center stores data between 1 exabyte and 1 yottabyte There are a lot of tricks for digging up information about Google's operations. Ironically, many of them involve using Google itself—from Googling for job postings in strange cities to using image search to find leaked cell camera photos of datacenter visits.
Seems like a bit of a mystery The company is quiet about the subject, but estimates range as high as 2. Sign up for our Newsletter!

A contingency plan was signed into law last year requiring states dependent on the river to take voluntary conservation measures.
Still, Mesa officials say they remain confident about future supply while continuing to remind residents to limit their water consumption. In , Mesa used 28 billion gallons of water, according to Macdonald. City officials expect that to reach 60 billion gallons a year by , a demand Mesa is capable of meeting, she said.
Mesa passed an ordinance in to ensure sustainable water use by large operations and fine them if they exceed their allowance. Google has toiled for years to reduce the carbon footprint of data centers. Today, the facilities churn out a lot more computer power for every watt of energy used. In its environmental report , the company argued that reducing its energy use also makes it more water-efficient. The most common systems, known as computer room air conditioners, are energy intensive.
Evaporative cooling uses less energy, but the process requires more water. Google has paid more attention to water use in recent years. It relies on recycled water or seawater where it can to avoid using drinking water or draining local supplies. Google also says it saves water by recirculating it through cooling systems multiple times. From to , Google used regular drinking water to cool its data center in Douglas County, just outside Atlanta. Contact us at letters time.
