This one is sold on to VMware ;-)
VMware Infrastructure 3 is a hard act to follow. When VI3 was released, it not only set the bar for all virtualization solutions to follow, but was so polished that many shops put it into production immediately, with no ill effects.
This week's release of VMware Infrastructure 3.5 is intended to continue the trend of stable, function-rich releases from the leader in virtualization. Based on what I've seen in the beta code I've been testing, it'll be a close call.
I've been running VI3.5 in the lab for weeks now, using the code provided from VMware Inc.'s beta program. This includes the base products ESX Server 3.5, VirtualCenter 2.5 and the management client, as well as new features such as live storage migration and distributed power management. It also includes a bevy of new add-ons -- for example, an automated patch manager and a tool for capacity planning and physical-to-virtual (P2V) migration.
