FEATURED WHITEPAPERS

Core PCI Requirements for Windows and Active Directory NetPro

The Payment Card Industry Data Security Standard (PCI DSS) is a set of industry regulations imposed by the major credit card companies to ensure the safety, security, and integrity of cardholder data. Any business that processes, stores, and transmits cardholder account data must comply with this complex new standard, and must be able to demonstrate that compliance through automated and manual audits of their systems. This white paper looks at the key challenges and requirements of PCI DSS as it relates to Microsoft Windows and Active Directory, and shows you how a third-party software solution can help with PCI compliance.

Reduce Complexity and Cost - Windows Server Consolidation with Virtualization from Novell Novell

There are many compelling reasons for virtualizing Windows and Linux applications. Virtualization improves server utilization by allowing you to run multiple workloads on a single physical server. It reduces the number of physical servers you have to maintain, while allowing you to use less physical space and power while still improving scalability. All of these capabilities translate directly into lower costs, less complexity, and greater flexibility in your mixed IT environment.

Evolution of Internet powers massive particle physics grid

Inside the network that will help scientists discover the origins of the Universe

If you're a fan of particle physics (and really, aren't we all?), by now you know scientists are on the verge of opening the Large Hadron Collider, which will use ultra-powerful magnets to race proton beams around a 17-mile circular underground tunnel and smash them into each other 40 million times a second.


Recreating the early universe: Take a closer look at Large Hadron Collider


Besides being awesome, these collisions will produce tiny particles not seen since just after the Big Bang and perhaps will enable scientists to find the elusive Higgs boson, which – if theories are correct – endows all objects with mass. The Large Hadron Collider may also help scientists figure out why all the matter in the universe wasn't destroyed by anti-matter, which would have been inconvenient for those of you who enjoy residing in a universe that isn't a great vacuum devoid of life.

Perhaps just as complicated as answering these questions of origin, however, is setting up a worldwide network capable of distributing the mountains of data produced by the seemingly infinite number of particle collisions. The Worldwide LHC Computing Grid was set up to perform this task. Data will be gathered from the European Organization for Nuclear Research (CERN), which hosts the collider in France and Switzerland, and distributed to thousands of scientists throughout the world.

One writer described the grid as a "parallel Internet." Ruth Pordes, executive director of the Open Science Grid, which oversees the U.S. infrastructure for the LHC network, describes it as an "evolution of the Internet." New fiber-optic cables with special protocols will be used to move data from CERN to 11 Tier-1 sites around the globe, which in turn use standard Internet technologies to transfer the data to more than 150 Tier-2 centers.

"It's using some advanced features and new technologies within the Internet to distribute the data," Pordes says. "It's advancing the technologies, it's advancing the [data transfer] rates, and it's advancing the usability and reliability of the infrastructure."
