For a prospect customer there’s nothing better than a real-world implementation to realize the potential or a certain technology. And this is very true in an almost unexplored technology like virtualization.

Microsoft, which eats its own dog food since the Virtual Server 2005 era, just announced the complete migration of both MSDN and TechNet, two of the most popular web sites in the world, on virtual machines.

Microsoft kept the back-end database on physical boxes, but moved 100% of its IIS7 frond-ends on Hyper-V RC0 VMs with 4 virtual CPUs and 10GB RAM. The virtualization hosts (no mention of the brand obviously) are powered by 2 Intel quad-core CPUs and 32GB RAM (2GB are reserved for the Windows Server 2008 parent partition).

The performance report after this migration is very interesting:

• Hyper-V CPU overhead (as measured by the parent partition utilization) was 5% to 6% with linear progression as the number of requests increased.
• CPU over subscription (three four-processor VMs on an eight-processor physical server) resulted in 3% lower overall performance per physical server based on overall requests per second per 1 percent CPU.
• Requests per second per 1% CPU performance of MSDN over the previous physical server platform improved. This demonstrates to us the viability of efficient consolidation from dedicated older physical servers to shared virtualized platforms.
• Physical MSDN handled 21% more requests per second per 1% CPU than virtualized MSDN.

Are you a loyal Windows Home Server users? A fix for that completely obnoxious data corruption bug is on the way. Microsoft has detailed its plans to release a public beta of its Windows Home Server Power Pack.

The update will include a fix for the data corruption issues that have plagued the OS since its release.

In a message to potential testers the company said:

“Due to the nature of the shared folder data corruption bug (KB #946676) a broad beta test program with sufficient time for feedback is required. The time line for a final release will depend on this feedback and testing, in order to deliver a fix of the highest quality. To meet our goals for the beta test we need the number of beta testers who are actively using and testing the Power Pack 1 beta to ramp up very quickly”

The company is asking for anyone currently using Home Server to sign up to the beta to ensure the data corruption issue is fixed.

We posted about Windows 7 screenshot last month and you can see the Windows 7 features demo from youtube now.

Microsoft Corp has launched a new online service in 20 countries which will allow users to watch video clips at the same time as a network of friends and chat via Windows Live Messenger.

The new service called Messenger TV will offer a range of clips on MSN Video including MTV shows and music clips from providers such as Sony BMG.

The firm hopes the ability to watch clips with friends on different computers will create a new social experience and attract users who already spend hours on social networks.

“Online video has exploded in popularity over the last year, but to date it has been something people watch on their own. Messenger TV is set to change all that,” said John Mangelaars, the vice-president, EMEA, of consumer and online for Microsoft.

“Watching video online can now be a social experience, as people watch videos together, make comments and share reactions.”

The service will launch in 20 countries including many European countries, New Zealand, Australia, Singapore, Brazil, Canada and Mexico but not the United States.
