When it comes to entry level server virtualization, Citrix now has the free XenServer edition on offer. Previously known as the XenServer Express edition, XenServer is basically a mix and match of the earlier XenServer Standard and XenServer Express editions' features. The recently shipped XenServer version has features like live migration, shared storage support, centralized multi-server management plus P2V and V2V conversion tools.
While this edition does prove handy for organizations starting out with server virtualization, it lacks features such as high availability and historical performance reporting (essential from an enterprise standpoint). This is where Citrix pitches the not-so-free Essentials for XenServer options, which come in Enterprise and Platinum flavors.
