Technical and Commercial Comparison of Citrix XenServer and VMware
This document provides a technical and commercial comparison of Citrix XenServer and VMware vSphere, two of the leading server virtualization products on the market. As this comparison will illustrate, XenServer is a powerful and feature-rich alternative to VMware and distinguishes itself in number of areas—including its open architecture, performance, storage integration and total cost of ownership.
- Citrix XenServer is a free virtualization platform based on the open-source Xen® hypervisor and includes XenCenter™, a multi-server management console with core management features such as multi-server management, virtual machine (VM) templates, snapshots, shared storage support, resource pools and XenMotion™ live migration. In addition, Citrix offers advanced management capabilities in Citrix Essentials™ for XenServer™ product line. Citrix Essentials for XenServer is available in two editions, Enterprise and Platinum.
- VMware vSphere is a server virtualization platform that includes the VMware ESX™ hypervisor and associated management tools. vSphere is available in three different editions: Standard, Advanced and Enterprise Plus. VMware is also offering an Enterprise edition of vSphere for a limited time. vSphere servers are managed from vCenter Server, VMware’s multi-server management console. vCenter Server is purchased separately from vSphere.
