Here we go, Green Computing is coming ! Now Citrix give us the ability to switch off XenApp servers and switch it on only when the load on the power on server reach a limit. This is very very smart and I think this Power and Capacity Management for XenApp will be a success.   You can watch bellow the video filmed during the Synergy 2009 in Las Vegas : [flash http://www.citrix.com/tv/s/tv/players/ctv_viral_1_0.swf?ctv=354 w=486 h=412] And of course with your MyCitrix account you can download the Technical Preview here : http://www.citrix.com/site/SS/downloads/details.asp?downloadId=1689982&productId=186&c1=sot1349740#top  Soon I will release a test of this new toy but I have to finish first my XenDesktop how to and after I would like to put online my test with Netscaler VPX Tech Preview.

To day I read a very interresting blog, and I want to share it because now the service pack 2 for Windows Vista and 2008 is out, we have to know what's inside ! And Aaron Parker did the work and just blog all the terminal server related fix include in the SP2 : As you’re most likely aware, Microsoft has recently made available Windows Vista and Windows Server 2008 Service Pack 2. If you would like to know the details of every single fix and feature in the service pack, download this spreadsheet: Hotfix and Security Update List: Windows Server 2008 SP2 and Windows Vista SP2. What’s always interesting to me is what is in the latest service packs that will directly benefit Terminal Servers. The table below lists all of the hotfixes in SP2 that directly relate to Terminal Services, and it’s quite the list. So it’s time to get testing and deploying: You can read the full post here : http://blog.stealthpuppy.com/windows/windows-server-2008-sp2-whats-in-it-for-terminal-servers
