With the announcement of ESX Server 3.0 and VirtualCenter 2.0 (aka Virtual Infrastructure 3.0) VMware launched a series of whitepapers to clarify technical and marketing aspects of the new offering.
The third one of the series:
VMware® Infrastructure 3 delivers comprehensive virtualization, management, resource optimization, application availability and operational automation capabilities in an integrated offering. VMware HA, a new capability in VMware Infrastructure 3, helps customers improve service levels for any application by implementing cost-effective virtualization-based high-availability solutions that are both easy to use and easy to configure.
