Juniper realized networks were far more complex than they had to be, then simplified them. Next, Juniper hired a reputable, independent firm to conduct a research study comparing their results with Cisco's. There was no comparison. The independent firm, Lake Partners, determined a user could save up to 52.1% in capital costs, 44.2% in power, 55.3% in space, and up to 25.0% in operating costs. Outstanding savings, no downside. Learn more about it in this on demand webinar. Plus, you can download the slides and a transcript from the webinar console.

Early-generation server load-balancing technology has proven to be an invaluable asset, especially for organizations hosting widely utilized Web applications. Time marches on, however. Business requirements evolve, as do the processes and technologies used to fulfill them. The many changes and trends that have taken hold since SLBs were first introduced expose the need for enterprises to step up from a simple load-balancing solution to a more comprehensive application delivery solution . This paper is intended to serve as a guide for organizations looking to replace their early-generation SLBs, providing details on the top eight criteria to use during an evaluation process.

Will your PC run Windows 7?

By: Randall C. Kennedy - InfoWorld (US)(NA)  (11 Nov 2008)

Here's how to determine if your computer will run Microsoft's replacement OS for Vista

Windows 7 is coming. Will your PC be ready? InfoWorld's Windows 7 compatibility calculator, a feature in the free Windows Sentinel PC monitoring tool, will tell you. Note that we've based our Windows 7 compatibility calculator on the October 2008 prerelease version of Windows 7.

It seems like a straightforward question. However, in the aftermath of the Vista debacle , where many systems that were certified as "Vista Capable" proved to be anything but, the process of vetting new Windows-compatible hardware has taken on more complexity.

You simply cannot count on Microsoft to provide an honest assessment of Windows system requirements. And as the "Vista Capable" experience has shown us, Microsoft's vendor partners are no better.

Hence InfoWorld's motivation in developing the Windows 7 Compatibility Testing widget: the need for a truly independent tool that can evaluate a PC's suitability to run the next version of Windows.

Top 10 Windows 7 features for IT professionals

Find out more about Windows 7's actual performance and capabilities

By taking marketing, politics, and vendor-speak out of the equation, we're hoping to provide you with an honest assessment of your PC's runtime environment, factoring in hardware configuration, current stress levels, and workload composition.

How to get started

Note: As with all Windows Sentinel widgets, you'll first need to register for your free Windows Sentinel account, which my company (Devil Mountain Software) developed based on years of experience benchmarking system performance for Microsoft and Intel.

Once you've registered, download and install the DMS Clarity Tracker Agent from InfoWorld's Windows Sentinel page and allow it to collect data for a few hours during normal usage periods. Then load the widget and find out if you pass or fail (and if the latter, why).

What the Windows 7 compatibility widget looks for

The widget begins with an analysis of your system's hardware; specifically, the type and speed of your CPU and the amount of installed memory.

As a Vista-derived OS, Windows 7 will no doubt levy the same kind of performance "tax" (high overall CPU utilization spread across a massive thread pool) that hobbled its predecessor. Our tests on the first Windows 7 prerelease version that Microsoft made available in late October 2008 confirms that Windows 7 is very much Vista, with similar requirements. Experience has shown that, to get acceptable performance with Vista, you need at least two CPU cores.

Windows 7 will carry forward this baseline overhead while introducing new workloads (such as a touch interface and Web services) that Microsoft is only beginning to describe publicly.

I wonder if a slower under 2 GHz dual core with a solid state hard drive will be suitable since investing in a solid state hard drive may have a better return on performance and other gains.
