IBM developerWorks ran an article yesterday that looks at the two major data management approaches in the TeraGrid. TeraGrid is a massive Grid delivering computational resources to support scientific discovery. The Grid delivers 50 teraflops of computing power, 2 petabytes of rotating storage -- and supports seven different operating systems and a dozen distinct system architectures.
Even before TeraGrid secured an additional $150 million in funding earlier last year, the community at large has been following TeraGrid closely to observe how it reconciles the huge data demands of the research scientists tapping into its power. The top disciplines using it are chemistry, physics and molecular biology -- all of which have tremendous data sets under their purview, and all of which heavily rely on the ability to transfer, compile and analyze these data sets to drive scientific discovery.
In another recent TeraGrid press release, it's not just big science using TeraGrid, at least not directly. Scientists recently used TeraGrid to create a graphic simulation of the collision of two galaxies that will be used in the finale of a new planetarium show for the American Museum of Natural History.
The IBM article drills down on TeraGrid's use of GridFTP -- the popular extension to the FTP protocol that specifically enables large data transfer for Grids. The article also discusses TeraGrid's use of IBM's GPFS-WAN file system, which has introduced some interesting new features and security capabilities for providing a parallel file system on a Grid.

Ensuring acceptable application delivery will become even more difficult over the next few years. As a result, IT organizations need to ensure that the approach that they take to resolving the current application delivery challenges can scale to support the emerging challenges. This handbook elaborates on the key tasks associated with planning, optimization, management and control and provides decision criteria to help IT organizations choose appropriate solutions.

A common misconception is that mid-range storage requirements are dramatically different than that of a larger enterprise. Mid-range storage users may require less capacity, but they have similar functionality and management requirements. This ESG paper examines mid-range storage needs and reviews a new solution that adjusts size while retaining value, performance and functionality.
