56-slides-VMware虚拟架构解决详尽方案.pptVIP

This is a server. VMware introduced a single node hypervisor, ESX server back in 2001. That lets you partition up a machine to run multiple OS application combinations, driving utilization from 5-15% on up to 60-85%, letting people provision machines in a matter of minutes as opposed to days. We made sure that the same virtual machine could run on any hw configuration be it a 2 way, a blade system, a 32 way, a laptop. This removes huge amounts of logistical overhead from implementing things like disaster recovery. Then we added virtual infrastructure and now you can provision your virtual machines onto a layer that can span different hardware compenent. And then we introduced VMotion that lets you take a running virtual machine and move it without service interruption across physical machines. You can be serving a movie and the client watching will so no blip as the movie server is moved from one machine to another. This VMotion also lets you service a machine in the middle of the day with no client interruption, say you want to upgrade the memory or service a component. This is already a virtual infrastructure, beyond the single node hypervisor.
