Power Off Server Once In a While?

From my mailbag:

I turn off the PC at home or the office once in a while. Now, I've server at colocation center. Do we need to run server 24/7? I do reboot the server once a month. Is it advisable to completely power off a server once in a while instead of 24/7 running?

According to new independent tests Red Hat Linux pulls as much as 12% less power than Windows 2008 on identical hardware. It means Linux is better for reducing data center power consumption or electrical power consumption. From the report:

Our tests point to Linux as the winner of the green flag by margins that topped out at 12%. We ran multiple power consumption tests using Windows Server 2008 Enterprise Edition, Red Hat's Enterprise Linux (RHEL) 5.1 and SUSE Enterprise Linux 10 SP1 on four, popular 1U server machines, one each from Dell and IBM and two from HP. The results showed that while Windows Server 2008 drew slightly less power in a few test cases when it had its maximum power saving settings turned on, it was RHEL that did the best job of keeping the power draw in check across the board.

Now the million dollar question, how important is green computing / green computers to you? Would you make switch to save the power?

Some time my work force me to do detective work on MS-Windows boxes. Just like Linux / UNIX / BSD system , Windows machines get *owned* a lot. Recently while searching for information I came across couple of nice built-in windows command line security tools to determine if a system has been hacked cracked.

Fortunately, Microsoft has built numerous tools into Windows so administrators and power users can analyze a machine to determine whether it's been compromised. In this tip, which is the first of a two-part series, Author has covered five useful command-line tools built into Windows for such analysis.

Microsoft has announced Open Source Interoperability Initiative. From the announcement press release :

The Open Source Interoperability Initiative exists to foster more open engagement between Microsoft and open source communities. It will encompass a broad range of facilities, events, and resources supporting interoperability, including labs, plug fests, technical content and opportunities for ongoing cooperative development. Microsoft plans to publish APIs and protocols that are used by Windows Vista (including the .NET Framework), Windows Server 2008, SQL Server 2008, Office 2007, Exchange Server 2007 and Office SharePoint Server 2007 -- as well as their future versions. Also Microsoft will not require developers to license or pay royalties for this information. Specifically, Microsoft is implementing four new interoperability principles and corresponding actions across its high-volume business products: (1) ensuring open connections; (2) promoting data portability; (3) enhancing support for industry standards; and (4) fostering more open engagement with customers and the industry, including open source communities.

Microsoft also agreed not to sue developers of open-source software and releasing tons of API. More information available at:

FastCGI is a language independent, scalable, open extension to CGI that provides high performance without the limitations of server specific APIs. I'm very big fan of FastCGI. Almost all my Apache / Lighttpd servers are powered by php FastCGI.

Today Microsoft announced the official release of their FastCGI extension for IIS server version 5.1 and 6.0. New FastCGI module should improves the performance and reliability of PHP on Windows operating system.

Since early 2006, Microsoft and Zend have been working together on a technical collaboration with the PHP community to significantly enhance the reliability and performance of PHP on Windows Server 2003 and Windows Server 2008. As part of this collaboration, the IIS product group has been working on a new component for IIS6 and IIS7 called FastCGI Extension which will enable IIS to much more effectively host PHP applications.
