Features & Benefits

10 Minutes to Xen

Citrix XenServer� software is easily installed using either a CD or network based installation and it delivers the performance, security and openness of the Xen technology for x86 server virtualization. You can then easily create an unlimited number of virtual machines. All the tools required to get virtualized right away are included.

Supports Standard Hardware and Drivers

Citrix XenServer software fully utilizes the benefits of hardware assisted virtualization on both Intel� VT platforms and AMD� Virtualization (AMD-V�) platforms via Xen paravirtualization. This hardware support provides exceptional performance and response times that closely rival non-virtualized speeds.

Citrix XenServer software leverages standard Linux device drivers for the broadest hardware support of any virtualization platform.

Supports wide variety of local storage including IDE, SATA, SCSI, and SAS direct attached storage and more
Supports Fiber Channel based SANs with boot from SAN for diskless blades
Supports shared storage on iSCSI based SANs and NFS NAS filers

Built to Scale

Citrix XenServer v4 is built from the ground up with 64-bit support and the industry�s largest CPU and memory limits for virtualization. It can handle up to 32 sockets and up to 128 GB of RAM and allows each virtual machine up to 32GB of RAM.

Windows and Linux Guest Support

Enterprise Edition and Standard Edition configurations can easily handle an unrestricted number of both Windows and Linux guest operating systems. Windows support includes Windows Server 2003, Windows XP, and Windows 2000 Server. Linux support includes Red Hat Enterprise Linux, Novell SUSE Linux Enterprise Server, and Debian Sarge and Etch. (See the product datasheet for details on exact versions supported.) Windows guests require Intel VT or AMD-V x86-based hardware.

Based on Industry-Standard Open Source Xen

Citrix XenServer v4 is based upon the industry standard open source Xen 3.1 hypervisor, the creators of which continue to enhance and maintain it at Citrix. This open source software �engine� is a proven, rapidly evolving industry standard with broad support from virtually all the major hardware and software vendors.

Blazing Fast Performance

The Citrix XenServer advanced paravirtualization architecture offers near �bare-metal� performance on almost any x86 server. The product�s minimal software footprint enables the full power of the system to be dedicated to running virtual machines. Optimized guest drivers provide high speed I/O for enhanced disk and network performance.

Powerful Resource Management

To guarantee that compute power is directed to the most essential workloads that require them, Citrix XenServer Enterprise Edition allows administrators to set quality-of-service (QoS) priorities and levels for CPU utilization as well as disk and network bandwidth.

XenCenter Multi-Server Multi-Pool Management

All Citrix XenServer editions include XenCenter, a powerful graphical virtualization management interface that runs on any Windows desktop machine - no dedicated system is required to use its powerful unified management capabilities. It offers:

Management of single servers (Express Edition) or multiple servers in one session (Standard Edition and Enterprise Edition)
Full lifecycle management for all your virtual machines from creation, starting and stopping, to reboot, and uninstalls
Interfaces for creating new virtual machines from original sources or from network repositories, and for cloning them from pre-configured templates for efficient buildout of virtual infrastructure
Ability to suspend and resume virtual machines on the fly
XenMotion management for live relocation (Enterprise Edition only)
Global resource pool configuration (Enterprise Edition)
Integrated configuration of virtual storage repositories and networking
Real time and trended graphing of virtual machine and total server performance metrics including CPU, memory, plus disk and network I/O
Controls to adjust virtual machine resource allocation as demands change (Enterprise Edition only)

The Citrix XenServer software also supports a powerful Command Line Interface that runs locally or remotely for easy integration with your existing tools and scripts and XenAPI for integration with management tools.

Enhanced Serviceability

Citrix XenServer v4 makes it easy for users to collect information required to assist with support and problem resolution and to send it directly to XenSource support. Integrated hotfix management allows users to easily keep the software up-to-date.
