The 1-Petabyte Barrier Is Crumbling
CurtMonash writes "I had been a database industry analyst for a decade before I found 1-gigabyte databases to write about. Now it is 15 years later, and the 1-petabyte barrier is crumbling. Specifically, we are about to see data warehouses — running on commercial database management systems — that contain over 1 petabyte of actual user data. For example, Greenplum is slated to have two of them within 60 days. Given how close it was a year ago, Teradata may have crossed the 1-petabyte mark by now too. And by the way, Yahoo already has a petabyte+ database running on a home-grown system. Meanwhile, the 100-terabyte mark is almost old hat. Besides the vendors already mentioned above, others with 100+ terabyte databases deployed include Netezza, DATAllegro, Dataupia, and even SAS."
No porn collection jokes please.
Oh wait, that was petabyte...
I had been a Porn Collector for a decade before I found 1-gigabyte Porn Collections to write about. Now it is 15 years later, and the 1-petabyte barrier is crumbling.
Petabyte DBs are old news to techie porn collectors. They always mix their two favorite subjects into one. Tech + Porn = Petabyte+ Porn Database
I have to find my kid. Last time I saw her, she was with her Uncle Micky while he was having his morning martini.
They have many towns now with less than 50k people completely photographed, every street in high res. That has to be well over 1-petabyte, though I doubt it's all in one location, must be distributed?
How many Libraries of Congress are necessary to break the 1-petabyte barrier ??

Take a look at almost any large financial firm. The email retention system alone is much larger than a petabyte, and that's just dealing with the online media, not including what's spooled to tape. Due to deficiencies in RDBMS ssytems, each of the large firms usually develop their own systems for managing the archival system on top of the database.
Call me old fashioned, but I don't see why anyone but a search engine like google would need anything like a petabyte. You can have only so much useful information about anything. Sounds to me like, fill your garage with sh1t, build a bigger garage.
I remember encountering a 1+ petabyte database 10 years ago: it was the database to record and analyze particle accelerator experiment data at CERN. And it was built using a commercial object database - not relational. Oh but wait - the relational vendors have told us that OO databases don't scale....
That was ten years ago.
Google Maps' database is far bigger...
A base of 8 tiles, with each becoming four more smaller tiles, in two modes (map/satellite), and 16 zoom levels.
Each tile is approx. 30kB.
(((0.03* (8 * (4^16)))/1024)/1024) == 983.04TB right there.
My calculator doesn't handle numbers big enough for streetview. O_O
No, but I did throw granola at a deaf person once

Any organisation that wishes to be classed in any way professional knows that the value in it's databases has to be protected. That requires them to have the means to recover the data if something bad happens. A hot-mirrored copy is simply not good enough (one corruption would get written to both copies).
As a consequence, the size of commercial databases is limited by the amount of time the organisation is willing to have it unavailable while it is restored, in the case of a disaster, or the time taken to create/update secure, offline, copies.
Not by intrinsic properties of the database or host architecture
politicians are like babies' nappies: they should both be changed regularly and for the same reasons
... DB design and old data that should be purged. Color me unimpressed.
I'm convinced now that regardless of attempted discrimination, HUMANS are pack-rats. THAT I can deal with, as people can be trained to actually throw shit away. The problem is when lawyers get involved in the matter. Yes, most of the shit we have today in the corporate world we are FORCED to keep due to some insane lawsuit and follow-up "fix-it-forever" law that calls for us to keep a copy of every damn thing that flows electronically for the next 7 - 70 years.
Could you almost call it corruption? Yes, I can. The similarities between supply and demand feeding the corruption of oil companies can also be seen in data storage markets. Hard drives probably wouldn't be eclipsing 80GB if it were not for laws driving it that way. New personal computers with almost a terabyte of storage, yeah like Grandma is ever gonna fill that up. Give me a break.
Imagine having tens of millions, or just millions users - all of them with their records, history, targeted ads data. Or some mail provider that stores attachments in a database. Or a file sharing service like those you and I know. That's a plenty of information to manage. Add an overhead, and it's easy to overfill even the biggest database.
Also I agree with you that bad design might be a concern. Of course there's no big database that couldn't get on a "purge" diet.
Now seems to me we might have a problem with querying such a big bucket of random data. Imagine a query taking months to complete. We're gonna be there in another ten years.
And then we lose the capacity to make electricity. And we can use our CDs, DVDs, let alone magnetic media to... well, dig trenches.
Those pesky petabytes of data are going to doom us.
Plain old sigh.
The LHC will generate several PB of data per year, as will the Large Synoptic Survey Telescope. These projects aren't all that uncommon.

My porn collection has long since achieved infinity.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
That is all.
The world will only need 5 large databases.
None of them will never need more than 640KB^H^HMB^H^HGBMB^H^HTB of RAM and 32MB^H^HGB^H^HTB^H^HPB of storage.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
As soon as you have the capacity, people will fill the capacity. There's always more data to collect.

WalMart's data warehouse is already 4 petabytes: http://storefrontbacktalk.com/story/080307walmart.php
Just because I can hook a shark from a boat, I do no offer to wrestle it in the water.
Is the location of IBM's Managed Storage Services (MSS) division, which deploys SAN for customers in Boulder (including IBM internal) and other locations (over high speed fibre links) on IBM "Shark" (ESS) and DS6000/DS8000 devices. When I worked at IBM their marketing materials stated they were managing over 4 petabytes of data for enterprise customers out of that location alone - that was four years ago! That doesn't count for other MSS locations either, nor all the other areas where IBM implements large amounts of storage for customers. Remember, many if not most of IBM's customers are governments and Fortune 100 companies, particularly high finance. I think they've got some data.
So you want to talk about high levels of storage - IBM has the game covered, considering they invented the HDD.
I need measurements I can understand, like how many Keanu Reeves' brains is a petabyte? And could he hold it indefinitely, or would his head explode at some point? If the latter, can we get him started on it now?

Okay, I know that the article is refering to database, but the comments seem to have gone into the way of disc storage, so I will take the bait and go off topic.
Petabyte drives would not really be that unpractical of an application for people who like to archive stuff. I just filled up a 300 gig drive and a 750 gig drive with just stuff off of the DVR in under a year. While National Geographic HD may be compressed so badly that it barely looks better than HD, and a one hour show is under 2 gig, try archiving something with a higher bandwidth. For example, I recorded the Olympics, and saved the opening and closing ceremonies and all gymnastic events. A single 4 hour day saved is around 40 gig.
So, lets think media server for HD material. Let's just stick with HDTV for a while. Let's say that I want to archive on a media server a Blu-Ray disc. Let's for the matter of talking say that the movie takes up all 50 gig of the disc. Ten movies, 500 gig. 100 movies, 5 Terrabyte, 1000 movies, 50 Terrabyte.
Now let's say that we are an IMAX theater, and upgrading to the new Imax Digital standard. I read not too long ago that an Imax film is equilivant to 18k (most digital theaters project 2K, although some are now installing 4K systems). So, to keep from having these big massive films around of the 20 year old science documentaries that we keep in rotation, we get the digital versions of these. Does anyone want to do the math?
I am waiting for the day when neural implants can actually read the human brain, and as such, you can archive experiences to some type of storage medium. I am sure wikipedia has somewhere how much information the human brain processes a second. Now, I am sure we will find a way of compressing stuff, we can already do audio and video, so I am sure one day we will have the ability to compress smell, taste and touch, granting that we actually have a way of capturing these. Still, the amount of data would be massive, and will probably be a whole new avenue for the Porn industry.
Granted, these are extremes, but who would have thought 15 years ago when we first started hitting the 1 gig barrier, that in 2008 we would have discs used for storing movies that have a capacity of 50 gig, and we would even consider saving stuff at a resolution of 1920x1080 and have PCM sound at a bitrate of 4.6Mbps?
Give us the storage space, and we will find a use for it.
We've had petabyte databases on mainframes for a good couple of years. DB2 v9 on zSeries has two new tablespace types that make managing these humungous databases much easier.
So it may be news for the PC world but it's bordering on ancient history on IBM mainframes.
Sigs. We don't need no steenking sigs.
Seems that Yahoo made this claim months ago but for a 2 petabyte database. The article goes on to list a couple of others that have more than 2 petabytes of archived data. So it's safe to say that the petabyte data barrier has been broken for some time.
So when active, the Large Hadron Collider will generate the equivalent volume of data of 50 Libraries of Congress every second.
On the other hand, if you have the extra space, it invites the usual waste in the form of archive directories for closed-out years, development junk, etc. Spinning round and round, doing nothing.
Yep. That's exactly it. $200 today buys a 1 TB drive. $200 a few years ago bought a 1 GB drive. As the price has fallen the value of the HDD has risen relative to its cost. Those archive directories and development junk aren't being deleted because they have value. Sure, it's enough value to justify keeping them around when a 1 GB drive costs $200, but they are worth keeping around with a 1 TB drive costs that much.
They aren't "doing nothing" - they just aren't doing enough that it's worth keeping it until the price drops enough.
All of this is making the 1 TB drive considerably more valuable than the 1 GB drive, despite their original purchase price parity. This is long-tail economics at work. As the individual bits become worth less and less, the value in of the bits in total continues to rise, resulting in a completely new set of capabilities.
My DVR is an excellent example of this - it's a thorough change in the way that I watch television. Suddenly, it's a family event that we can all share, because when I want to comment, I can just hit pause, and share my thought. Nothing's lost, if needed we can just hit rewind a bit, and suddenly, instead of being annoyed at my daughter for wanting to comment on a point during a televised debate, I'm excited and interested! No more SHUSHSTing at my family, it's now a much more shared experience.
The price of nonlinear access media has dropped so incredibly that marginal-value bits (like video) are suddenly cheap enough to make it all possible.
I have no problem with your religion until you decide it's reason to deprive others of the truth.
