- Cost effective
- Overall simplicity
Since XenServer was the chosen platform from the start of our virtualization implementation, the improvements have been significant. Such improvements include the overall reduction of physical hardware, more efficient use and allocation of hardware resources, recovery points, storage utilization (when combined with dedupe), functional delivery of role based servers, and overall server management.
Basic deployment is very easy. Multi-pathing storage does require a more advanced level of switching knowledge, but there is no shortage of documentation and examples to help implement.
Like any solution, plan your storage and networking wisely.
XenServer hosts have never had stability issues. The guest tools have definitely had stability issues.
Never had issues with scalability. In fact, I even had good success with processor masking in order to extend some life in an older server that was performing well.
From a customer-service perspective, there really isn't much that can be said. I don't have Citrix calling me to discuss XenServer. All service is community driven.Technical Support:
Throughout my use of XenServer, I've opened about 3 cases with Citrix. Each time the engineer I worked with was very knowledgeable and always assisted in resolving my issue.
No other option was used. I tested Hyper-V and, at the time, MS did not have a good solution to live migration.
Setup was simple and quick. I was able to begin with local storage and move my virtual machines to network storage at my leisure without any issues or downtime.
We've used standard networking, iSCSI multi-pathing, and bonded NFS. All have worked well.
