I was just attended the session this morning talk about the virtual layer security after consolidation, virtualization and cloud computing environment. As many of the users previously adopted to virtualizaton, most of the time the security consideration were minimal due to the technology limitation of that time. But today, vmware and their solution partner had produced large number of solutions available in the market which can help the users to further strengthen the security readiness after virtualization. Example will be vmware vshield edge, application, cisco nexus 1000v, cisco vsg, check point and etc. All these products was focusing on similar thing which try to off load the necessary work load from the current virtual machines to the hypervisor or virtual switch level. This will able to prevent antivirus scanning storm, performance issues and etc.

It was a long journey for myself to reach vegas 10 hours ago, which took me more than 17 hours flight in total to reach my hotel . I am very excited to join this event which allow myself to explore many opportunities around the globe surrounding the Cloud and Virtualization. I will try my best to perform necessary blogging during the event, but this may need to check out the internet connectivity in the conference as I do not have the 3G coverage with my Roaming due to incredible expensive rate.
Again, finally I am here and I hope this will not be the first and my last trip to the VMworld event. I always wish there are more to come.
I would like to thank you my bosses who fully support my trip to Vegas and my friend from VMware who encourage me to attend this event.

Cisco had recently added new Fabric Interconnect to their product line up which provide more choice to their client to be consider for their deployment. Previously there were only 6120XP and 6140XP in place for the Fabric interconnect architecture as part of Cisco UCS. The new Fabric Interconnect 6248UP which provide 32 ports FCoE with additional 16 ports expansion module on unified port available which support FCoE, LAN and SAN FC with appropriate module.
While introduce new Fabric Interconnect, the IO Module for UCS Blade Chassis had been further enhance with 2208XP which provide 80Gbps throughput per IO module, and allowed up to 160Gbps per chassis. This option will allow users to provide higher throughput to the blade infrastructure which require more than 80Gbps per chassis.

Went through a marathon troubleshooting with my client for the past 1 week to figure out the reason why a cluster failed in place and it could not easily rebuild back after 1 of the node evicted. We had gone through the process to re image both nodes and rebuild from scratch. Follow exactly the best practices and run through the cluster validation without any error. While we try to form the cluster, the system keep provide an unknown error which do not share much information from log. It just keep telling you that the node is not reachable or unauthorized due to security setting.
After few nights of troubleshooting, I was running out of clue. Came to the sudden, I accidentally search the computer name in AD under the category of Users object group, and I found an user account been created in AD with the same name as we define on the cluster name. I was wondering whether this could caused the confuse to the system. Therefore, I was suggesting to remove the user name temporally as it was not use at the moment and tried to reform the cluster. Guess what, the cluster form up as it needed to be in less than 1 minutes. We were so happy to end the marathon troubleshooting every night well and we were also very pissed off with the bugs we face here.
