  2. 2. Comparing Xen Open Source to XenServer • Xen hypervisor is the core virtualization engine for both the open source and XenServer products • Is supports paravirtualization and hardware virtualization assistance. Both products offer stable, tested components • Differences between Xen open source and XenServer include: • Xen open source code includes unstable or untested components • Citrix XenServer products are rigorously tested and include polished features for heavy production use 2 © 2008 Citrix Systems, Inc. — All rights reserved
  3. 3. Comparing Xen Platforms XenServer Xen Open Source • Citrix XenServer Enterprise Edition • Xen supports the following 4.1 supports the 64-bit hypervisor hypervisor versions: version • 32-bit • 32-bit-PAE • 64-bit • Citrix Xe • Xen has the following theoretical • nServer supports the following CPU memory and CPU limits: and memory limits: • Terabytes of memory • 32 CPU cores • 128 CPU cores • 128 GB RAM • Xen requires Linux experience to • 75% of the code is proprietary which install. Installation usually takes one makes XenServer easy to use. day to install Installation usually takes less than 10 minutes 3 © 2008 Citrix Systems, Inc. — All rights reserved
