Flash Wozniak's new favorite - Computer Sweden

Fusion-io’s flash memory installed in the computer as an extra card. It communicates directly with the processor through the PCI bus.

Steve Wozniak, Apple co-founder, IT legends and now chief scientist at Fusion-io.

Steve Wozniak, founder by Apple, is still more famous than the Fusion-io, the company where he is chief scientist.

– The many companies that want to have with me on the board because they want to be associated with my name, ‘he said at the conference IP Expo on Tuesday. They’re never the door. I started working on Fusion-io because I wanted my name to be associated with Fusion-io.

Fusion-io’s technology solution to speak Wozniak’s mind for radical simplification.

That Apple uses technology from Fusion-io is hardly Wozniak, whose role in Apple nowadays is merely nostalgic. Even Facebook uses Fusion-io’s technology. In both cases it is about huge data centers that handle millions of transactions every minute. Facebook’s users upload posts, comments, photos, videos and links. Apple is acting on iTunes and iBooks and synchronize their computers, PCs and mobile phones. Everyone expects immediate results.

what Fusion-io’s technology do is replace reads and writes to the hard drive with a direct line to a flash drive.

With a combination standard servers and Fusion-io reduces costs by half and you only need a third of the space, said Fusion-io’s product manager Gary Orenstein.
Fusion-io’s flash memory is no SSD (flash disk ). It is not a flash memory that behaves like a regular hard drive. It is a short, slightly bigger than a candy bar, which houses three terabytes of flash memory or more. And the card is connected directly to the computer through the PCI bus.

flash memory, which of course as a regular hard drive does not lose data when the power fails, thus functions as a part of computer, much like a graphics card.

And it does a big difference when you learned to exploit the news.

To write to disk is namely a bottleneck, although we are using the computer for word processing and web surfing are not disturbed by it. Even if the duration is measured in microseconds, it is written to disk a little winded. The time required to write to and read from Fusion-io’s flash memory is much smaller.

time saved is not on the computer is so much faster, but it Rather, the cumulative effect of millions of small transactions between operating systems and storage memory alone is much faster and more rarely have to wait for each other.
Cache principle – frequently requested data is stored in fast memory close to the processor – can be seen as a application of the Fusion-io.
Memory Databases, ie databases that only run in the working memory, the most radical way to speed up processing. Fusion-io’s flash memory technology is not as fast, but it is safer – no data is lost if the power goes out.

Last big customer for Fusion-io is Spotify. Another collaboration is with MariaDB database, the Finnish branch of MySQL, as Fusion-io also cooperates. Fusion-io’s technology allows writes to databases can be simplified and speeded up. The procedure to prevent changes to the database only implemented half can namely be simplified when working directly in the flash memory. One does not write to a buffer first. Therefore, it is almost twice as fast. In addition, flash memory lifespan longer:

class=”paragraphIntro”> – A flash memory lifespan can be predicted with high accuracy, says Gary Orenstein. If it halves the number of writes to the flash memory to hold it twice as long.
