Two European scientists, Albert Fert (France) and Peter Grunberg (Germany) have won the 2007 Nobel Prize for physics for their research into Giant Magnetoresistance, or GMR. GMR read/write heads are used in IBM disk systems.
Chris Evans points to an interesting "jet analogy" in his post[Your Data On a Knife Edge].To help people understand that significance of this innovation, IBM Research has a website with all kindsof useful GMR information: http
While many people associate GMR heads with disk drives, it also applies to tape.In 2006, IBM Researchers Set World Record in Magnetic Tape Data Density, recording 6.67 billion bits per square inch of tape media. This was achieved with specific developments:
IBM often leverages the research done in one part of its business over to other parts of its business. In this manner, advances in disk translate into advances in tape, keeping tape a viable medium for at least the next 8-10 years.

Congratulations go to IBM blogger Barry Whyte!
Network World, the folks who last year rated this blog in the Top 10 IT storage blogs, havejust put out an article on The best and worst vendor blogs, identifying the companies that make up the good, bad and ugly on the blogosphere. This time, they recognize Barry Whyte'sStorage Virtualization blog under the "Good" category, representative of IBM'sefforts corporate-wide on the blogosphere.Read More]
Registration is still open for next week's Information On Demand 2007 conference, Oct 14-19, in Las Vegas, Nevada.
This will be a huge event, bigger than last year's, covering the storage of information, e-discovery and compliance, data management, and other related topics.
Weather should be nice next week, 80 degrees during the day, 60 degrees at night.Read More]

As BarryW points out, IBM System Storage SAN Volume Controller (SVC) is now[fully certified with VMWare ESX 3.0.2]. Here's the [official IBM press release]. This is based onthe [Storage Virtualization Certification Program] announced by VMware last week.
This is great news for everyone. I have said before that VMware is perhaps the best product EMC offers, and some EMC bloggers have returned the favor saying that SVC might just be the best disk system that IBM offers. While IBM and EMCare heavily competitive in other aspects of the IT storage industry, when it comes to delivering what is right for the customer, we can set aside those differences. IBM is the number one reseller of VMware, and it is a great pairing with SAN Volume Controller.
Of course, it is not a free-for-all. VMware has a few restrictions at this time:
Of course, most of these issues can probably be addressed with additional testing, or minor software changes, and IBM will work with VMware to prioritize what added testing or software changes are needed to expand this support.Read More]

Welcome to my blog on IBM Developerworks!
I am Tony Pearson, storage consultant at the IBM Executive Briefing Center, located in Tucson, Arizona. I have degrees in Computer Engineering and Electrical Engineering from the University of Arizona. Over the past 20 years, I have worked in a variety of storage roles, including development projects, product and portfolio management, testing, field support, marketing, and now am doing storage consulting.
There are a lot of things to discuss related to storage, and I am never short of opinions. As such, the standard IBM disclaimer applies: “The postings on this site solely reflect the personal views of the author and do not necessarily represent the views, positions, strategies or opinions of IBM or IBM management.”
I have invited other IBMers to post their opinions, and when they do, their opinions may not necessarily match mine either.
This is an open two-way conversation between IBM, Business Partners, Independent Software Vendors, prospect and existing clients. I encourage everyone to post comments about our products, services, and marketing efforts.
