I wonder what makes up the majority of that data, pointless status updates or mafia war invites.

25Tb of pokes

See, you can write bad code and just throw more hardware at it.
10.18.2009
So one server per 10,000 users? I wonder what Digg has?
10.18.2009
50% of it is probably Mafia Wars and Farmville.
10.18.2009
But can they run Crysis?

Google considers 25TB of data to be a small rounding error.

I’m pretty sure it’s, by far, pictures. 20 billion unique pictures, each in 4 different sizes, according to the article.
10.18.2009
That’s crazy.

Not nearly as many servers as Google.. estimated to be over 700,000 servers…

I’d like to see their database structure. I bet it’s insane.

Someone explain to me how Facebook calculated 25 terabytes into "1000x more mail than the post office delivers everyday". I tried using google calculator but it doesn’t have the units "mail".

On the plus side, when an earthquake happens and the servers sink into a chasm, they’ll be a rush to be the first to comment on the Digg article about it (assuming that the Digg servers don’t join them) with, "And nothing of value was lost."

**Hu99 is having breakfast**
10.18.2009
Yea…something like 30,000 I’m guessing.

"(stupidly) MySQL"? What would be a better alternative?
10.18.2009
Looks like domestic spying just a whole lot easier
10.18.2009
Man I have to facebook about this!
10.18.2009
The rule of thumb with this kind of thing is that 11 users out of 100 will be actively using whatever it is they have an account on at any given time. So out of 10,000 users, one can expect 1,100 users actively using that server at peak load. Out of that, with facebook, you’re mostly talking about database reads. Though their backend is (stupidly) MySQL, even it can easily handle the "clicker", which probably amounts to somewhere around 3-5 simple queries per second, and likely somewhere around 1 insert (upload/change) every two seconds.If what is implied in this article is true, you frankly don’t need anything bigger than a quad core xeon, 8 gigs of RAM, and a three year warranty for each 1u server— which all run Linux, so software licensing (between the OS and the database back end) costs nothing.Digg isn’t anywhere close to as complex. I can’t imagine the LAMP machines that Digg requires needing to be anything bigger than a third of what facebook uses per same number of users.

And the "Basic Programming" cartridge.
10.18.2009
Seriously, What is so great about those things?

That’s what I was going to say.All that computer power going to waste.

Think of all the fun things you can do with that extra space!

Actually, it’s Facebook.

Facebook is still unbelievably ***** slow

…and still not a single dollar of net income. The clock is ticking. Remember 1999?
10.18.2009
That’s over 9,000 servers.
10.18.2009
Just think about google, facebook doesn’t feel so crazy after all?
10.18.2009
So don’t upload them there. Problem solved.

Probably could have converted mail into bits by taking the average number of words/images per piece of mail.
10.18.2009
Such a waste of hardware
10.18.2009
My boss once suggested we may need a 5 TB harddrive to back up our website (Which is about 30 MB). I’m tempted to show him this to illustrate his lack of technological knowledge, but I prefer him to think he’s an expert and not know what I do.

If it crashes nothing of value will be lost.

They don’t use a standard relational database but instead use Cassandra: incubator.apache.org/cassandra/Interesting read about the "No-SQL movement": 25hoursaday.com/weblog/CommentView.aspx …

why didn’t you just delete your email addy instead of taking the cap it into mspaint to scrawl that red mess over it?

OVER 9000!

I think you mean 8Tb = 1TB, no?

Wow. I’ve run a small forum/ blogging site since mid February. The database is currently 8.3 MB. Puts things in perspective.
