I just got the official release of vSphere 4 today and finally got it work on my test lab. 1st thing before I upgraded my ESX servers is I need to upgrade my vCenter. If you are running RC now, you may not able to manage the official release vSphere 4 host by RC version of vCenter you had. I reinstall fresh for my vCenter 4 on Windows 2003. Since is a test lab, I do not build the DB on SQL Server as I did for production. I am using the default sql express as part of the installation.The installation process will not be much different compare to RC, but the resource utilization of the vCenter 4 will make the different.

As vSphere is on the way, many of you may had experienced to test the RC release now. 1 of the thing you may notice is about the performance on vCenter 4 which bundle as part of the vSphere infrastructure in the coming release.

The resource require to run the SQL server will not make any big different in this case, but you will notice the tomcat process in the task manager will take up quite a number of resources from your vCenter server.

A datastore is platform-independent and host-independent and it can reside on the local disk of an VMware ESX/vSphere Server, or they could be on a storage area network (SAN). Therefore, datastores do not change when the virtual machines they contain are moved between hosts. The scope of a datastore is a datacenter; the datastore is uniquely named within the datacenter. They can be accessed by either the VMware Infrastructure Client/vCenter client or by the Web interface.

I had just read through some articles and watch the video from Microsoft about the top 10 VMware Myths today, I would like to share my thoughts about the video details published by Microsoft with unbiased opinions.
The guys talked about Live Migration on HyperV on the next release. As a customer, I am always believed that the software provider should only commit and tell the customers when their products are ready, and not always tell the customer WE ARE READY IN THE NEXT RELEASE. This only explain as your product is not ready, what about your next release is in 2 years time? That meant the products is not as promise as you publish to the customers. Please take note that VMware had supported Storage VMotion for current version, which is another step beyond of Live Migration.
