VMware ESX Server 3.5
Latest Version: 3.5 12/10/2007 Build: 64607 Release Notes
ESX 3.5 Server is a major release that will deliver several new features.
As I see it, Storage Vmotion is the largest feature, however it's not included in these downloads and must be downloaded as a separate component. Migrations using Storage VMotion must be administered through the Remote Command Line Interface (Remote CLI), which is available for download here.
