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.

I got a big shock for the first email I read this morning is regarding the sad news of the Legend Steve Jobs who left us 1 day right after the iphone 4S launching. I had always admire his talent and vision as a Technology leader since I was a kids and the days I know about Computer. I always told my friend about how a success leader just like him had made the changes to our life today. Some people may not agree with him, but they do see him as a target for competition. For my personal opinion, he had changed the living style that I have today compare to 20 years ago.

Interesting announcement from Cisco and VMware during the VMworld 2011 which was regarding the VXLAN capability. Both company had invited a group of product principle together to submit the VXLAN to IETF for approval as a standard for future.
Let’s talk a little bit more about what is VXLAN and why do we need that. As of today, DR solution are commonly deploy by every enterprise environment. Did you realize 1 of the biggest challenge which always happen on the DNS record, hard coded IP segment, subnet and VLAN which always require human interaction to manually change it, to allow a success fail over of the DR scenario? Well, I think this is just 1 of the major issue commonly face. With Cisco Nexus 7000 come with OTV (Overlay Transport Virtualization) which allow you to stretch the Layer 2 traffic over Layer 3, with minimal bandwidth requirement. Cisco had done a great job to the enterprise to address this, which now you can have both side learning the same VLAN, Subnet and ip address. A DNS and ip changes is no longer require as both end are transparent with similar VLAN.
