  • IBM Researchers Push Tape Densities in the Lab

    May 22, 2006 Timothy Prickett Morgan

    Anyone who thinks that tape technology is dead doesn’t know anything about data centers, and hasn’t felt the bile in their throats when a server crashes and all that is standing between themselves and a lot of grief is a set of data that they have thoughtfully backed up on tape. Tape matters, and it will continue to do so, and that is why IBM continues to do research to advance the magnetic tape technology it helped create decades ago.

    Researchers at IBM’s Almaden Research Center in San Jose, California, last week reported that they have created a tape technology that was capable of storing data at a density of 6.67 billion bits per square inch. That works out to be about 15 times as dense as the current state-of-the-art tape cassettes used in the IT industry. IBM researchers worked with partner Fuji Film of Japan in the technology demonstration.

    By showing tape can get denser and stay on the price/performance curve that tape technologies have been following (like chips and memory circuits) for the past several decades, IBM says that within about five years it will be able to deliver a tape cartridge that holds about 8 terabytes of data in something about the size of today’s LTO tape cartridge. That’s about 20 times the density of the LTO-3 tapes. And, because IBM press people are silly, they did the standard conversion to books to make this number sound more “real” to non-techies, and I would be remiss if I didn’t report it to you for a chuckle. “Eight terabytes of data is equivalent to the text in 8 million books, which would require 57 miles of bookshelves,” IBM’s statement read. As if any of us thought of data in terms of sheets or paper or books any more.

    Let’s do some different math here and show you that 8 terabytes of data is nothing in a world with gigabyte email accounts, streaming media files, and high resolution graphics. An iPod with a 60 GB drive holds 15,000 songs or 25,000 electronic photos. (Yes, that is a lot of songs. My entire CD collection, which I have spent almost 20 years creating, has about 9,000 songs in it; I don’t have anywhere near 25,000 photos.) To put that 8 TB into a better perspective, such a future tape cartridge would be sufficient to archive of 136 of the current 60 GB iPods if they were full of songs. When you say it that way, it just doesn’t sound like a lot of data, now does it?

    Get More Out of Your IBM i

    With soaring costs, operational data is more critical than ever. IBM shops need faster, easier ways to distribute IBM applications-based data to users more efficiently, no matter where they are.

    The Problem:

    For Users, IBM Data Can Be Difficult to Get To

    IBM Applications generate reports as spooled files, originally designed to be printed. Often those reports are packed together with so much data it makes them difficult to read. Add to that hardcopy is a pain to distribute. User-friendly formats like Excel and PDF are better, offering sorting, searching, and easy portability but getting IBM reports into these formats can be tricky without the right tools.

    The Solution:

    IBM i Reports can easily be converted to easy to read and share formats like Excel and PDF and Delivered by Email

    Converting IBM i, iSeries, and AS400 reports into Excel and PDF is now a lot easier with SpoolFlex software by DRV Tech.  If you or your users are still doing this manually, think how much time is wasted dragging and reformatting to make a report readable. How much time would be saved if they were automatically formatted correctly and delivered to one or multiple recipients.

    SpoolFlex converts spooled files to Excel and PDF, automatically emailing them, and saving copies to network shared folders. SpoolFlex converts complex reports to Excel, removing unwanted headers, splitting large reports out for individual recipients, and delivering to users whether they are at the office or working from home.

    Watch our 2-minute video and see DRV’s powerful SpoolFlex software can solve your file conversion challenges.
