Hyper-V Released

Today Microsoft released Hyper-V 1.0, their bare-metal hypervisor. I haven’t been able to find much information on the Internet about it yet other than Alessandro’s announcement and this article at Network World; there was nothing on the Microsoft web site about it at the time of this writing.

Melio FS, Hyper-V, and VMware ESX

Last week Network World published an article about Sanbolic’s announcement to provide VMware virtual machines access to shared application data using their shared file system, Melio FS. This announcement was made last week at Tech-Ed 2008 in Orlando, FL. Sanbolic also announced support for running Melio FS in VMware Infrastructure 3 (VI3) environments as well. Unfortunately, the information in these announcements seems to have gotten jumbled while being reported and now these two very different uses of Sanbolic’s products are being intermingled when they really shouldn’t be. Allow me to explain.

One More Tech-Ed Schedule Change

I have to swallow my pride and admit defeat: the amount of information at Tech-Ed 2008 has overwhelmed me. I’ll be skipping my last session, a session on Server Core, to return back to my resort and prepare to fly home early tomorrow morning. If you were looking for some information on Server Core, I’m sorry to disappoint you!
