XenServer 6.5 is out!!

Last summer I started blogging about interesting things going on in the XenServer team (see Rumblings at XenServer.org and Ramping Up XenServer).  Today I’m pleased to say that all that hard work has paid off.  XenServer 6.5 (formerly codenamed Creedence) is the best release of XenServer ever.

So, what’s new in XenServer 6.5? A lot of good stuff!

  • All 64-bit
  • Massive performance improvements
  • 50% increase in GPU density
  • The return of the popular Workload Balancing (WLB) appliance
  • Numerous usability enhancements

So, let’s talk about some of these performance enhancements.  While XenServer has long been known for it’s world-class compute performance, we realized that more and work workloads are now becoming I/O bound.  Thus, the team put massive effort into improving the data path through the networking and storage systems.  Here are some sample benchmarks comparing the performance of XenServer 6.5 vs. XenServer 6.2 (the last major release).

Who should be interested in XenServer 6.5?  Firstly, anyone who’s using XenServer today will find this a major step up.  Upgrade today and see the difference.  Who else should be interested?  Are you building a cloud?  Xen project is the most popular hypervisor for the cloud and XenServer is the most popular, commercial distribution for Xen project.  XenServer is an efficient, cost-effective and battle-tested choice for your cloud?

Are you running XenApp or XenDesktop?  XenServer is your best choice for those environments as well.  Not only is XenServer included for free (saving you substantial cost), but you get a single stop for support.  Perhaps even more importantly the XenServer and XenDesktop teams work together closely to bring you world’s-first access to new technology like vGPU-enabled, remote desktops.

Are your virtualizing Enterprise computing workloads?  XenServer is a high-performance, cost-effective, easy-to-use option for your needs.  With no separate management server required for features like live-migration and HA, it’s can’t be easier to get started.  And, with years of experience running both Linux and Windows workloads, it’s a great choice no matter which OS you’re virtualizing.

The XenServer team is firing on all cylinders right now, and there are many more innovations that are in the pipe for the coming year.  Engineers are already at work on our next two releases and they’re going to be pretty exciting.  Stay tuned for more details on that here.  Wait until you see what we’re doing with Linux containers!
