Posted on October 11th, 2011 in Announcement, Tips, Virtual Desktop Infrastructure, Virtualization, Xen, Xen Desktop | No Comments »

While I am attending the training for XenDesktop today, we had covered the topic of License Server for Xendesktop.
I had raised the question to the trainer.

what if the license server go down, will all the existing connections or sessions been terminated automatically?

He had explained as the configuration in the license server and license files are design to prevent the point of failure in the scenario of license server unavailable due to any failures. You will be given 28 days period of time with unlimited seats in the event of license servers unavailable during the outage.

In normal scenario, assume your license server is functioning with 1000 seats, you will also allow to provision 10% extra within 28 days before you increase the purchased licenses. This will allow you to turn on extra capacity temporally in the short period.

Virtual Machine could be fail over during hardware failure, how about services failure or the application client server dependency issues? Example : There may be the application or middle ware machine require manual restart during a HA kick in scenario.

Xencenter doesn’t work on Windows 7

Posted on March 20th, 2011 in Tips | 10 Comments »

If you are trying to install the Xencenter on Windows 7, you may face an error which due to the pre-requirement for .net framework 2.0 as part of the installation. It will fail automatically as windows 7 doesn’t support with .net framework 2.0 anymore. As there are number of solution posted on the internet, but is not easy to resolve this issue. Most easiest way is to get an XP machines install with the xencenter and manage the Xenserver and VMs from there. It just weird that the support on windows 7 is not available up to date, Citrix need to react faster as Windows 7 adoption is big wave going on to many enterprise and newly purchase desktop and laptop.

Nice Video of the HyperV that you will not want to miss out

Posted on May 6th, 2009 in Hyper-V, Industry News, Server, Virtualization | No Comments »

I had watched the nice video which posted by Duncan from yellow bricks days back. The video had showed some “GREAT” result and excellent BLUE SCREEN that every administrator will not want it to be happened to themself. Windows Servers running on HypverV and getting bunch of blue screen is not a joke. You should reconsider to put your mission critical environment with HyperV rather than VMware and Xen.

You can read more about the article from here and watch the nice video too.

Have fun.
