 And we, you know, we all know about Apple and Facebook have massive amounts of constraints and it has a lot to do with the storage and IO. So let's talk about your manifesto, your research piece that you posted, called the IO infrastructure, IO centric infrastructure, a little bit further. What was your key findings in your research? Well, the key finding, and I've been talking about it for some time, is that the disk systems themselves are the constraint on so many applications. If you're going to make sure you have guaranteed delivery of data, you have to put it onto some sort of disk. That's the only way you can guarantee that you'll find it when the system goes down. So that is, that constraint of disk is that disk is just so, so slow and very, very narrow path to a huge amount of data. And they have not been speeding up at all. The amount of data you can store is massive on disk. It's very cheap per gigabyte. But the cost of it per IO has not come down at the same rate. So what's interested me is the use of flash devices. One of the things that happened very recently, which was seminal, was the demonstration of a billion IOPS system. It just took eight of these processes with 64 cards to deliver a billion IOPS. That was between Fusion IO and HP in San Francisco just a few weeks ago. And what I did in this one... Hold on, just to back up a second. So HP and Fusion IO, so HP servers. HP servers. And Fusion IO. Proline 370 servers and Fusion IO, the IO memory cards, memory to Duo cards. Which is SSD or flash, right? Yeah, which is the SSD, solid state, MLC cards. So an amazing amount of density of IO that could be generated. Now very small IO's, 64 bytes only in size. So a very trivial in size compared with most applications. But really an amazing achievement.
