Citrix Hypervisor

XenServer is well suited for all scenarios for deployment for a modern infrastructure. The weak link it has is of course for classic physical hardware that has key fobs or other telephony cards which aren't properly supported in a virtualized environment. Even if you have one physical server, virtualizing is the best practice to do.

Oracle VM Server

Oracle VM Server is well-suited for long term deployment where you have to invest a lot. But, it is best recommended in the development phase and UAT, as there is a lot of services that are missing

Pros

Citrix Hypervisor

  • Manages upgrades to the pool of hypervisor hosts with relative ease through a console (if licensed).
  • Makes it easy to create machine templates and clones and move them around within the pool of hosts.
  • Handles failures reasonably well through the use of the pool database copied on each host

Oracle VM Server

  • Supports x86 and Solaris servers.
  • Cloning VM's is a very important feature.
  • Another extremely useful feature for us was the Live Storage Migration.
  • By the way, Oracle VM is free!

Cons

Citrix Hypervisor

  • Support - if free is what you need, great support is not what you'll get, keep in mind if support is necessary
  • Upgrades - the upgrade process is buggy and problematic at best
  • Partner Support - if you're looking for a product with multiple parters rolled in, I'd look elsewhere

Oracle VM Server

  • Management/GUI is uncomfortable.
  • Remote control via VNC is hard to use with graphic interface and for terminal we have SSH configuration and maintenance is not as straight forward as in VMware, Xen or even Microsoft Hyper-V.

With the knowledge and usage of solutions from VMware and Microsoft offering more compelling cloud integrated options it makes it more compelling in many environments which I consult. XenServer is a good product and fits the bill in many smaller environments but as clients look to the cloud or a hybrid cloud it can in some cases make it a bit more difficult.

Usability

XenServer is quite usable due to the simplicity the management and installation provide for an administrator. The console for management is very intuitive and can easily be installed on any Windows operating system. There is a relatively simple web console that can be implemented as well that enhances the usability to provide service to non-administrators.

It's been a little problematic in the past at larger VDI deployments requiring a bit more care and feeding than other vendors. But the latest releases (6.5.x) have brought about huge improvements in the stability and availability.

When running like a top XenServer is a fantastic hypervisor. There is relatively low overhead on the Dom0 so workloads get the most of the resources.

Anytime I had to request support from the Citrix Hypervisor website I had an instant answer and it was straight to the point. I also used the forums available to everyone and always had success from both the technical staff and from the community.

Part of a training for certification to become a trainer for Citrix included an in-person training with a Master CCI. The XenServer training at this time was pretty simplified due to the product primarily being installed however you did have to work with it and mildly configure the system.

Online Training

Citrix Hypervisor

Haven't given it a real go with any online training however there are some options out there. I have taught a course following Citrix material for XenDesktop which leverages XenServer and it is pre-built so not the best for XenServer specifically for installation but configuration is mildly touched on

Ensure you review the HCL (hardware compatibility list) and reach out to the hardware vendors to ensure they support the platform and in case they have documentation that can be followed for the implementation. Also ensure the prerequisites are completed prior to implementation so that as few unexpected delays occur as you can control.

Alternatives Considered

Citrix Hypervisor

The price is very good. Also, the support from the vendor in the process of implementation and maintenance is very important. Citrix offers this support. The implementation was easy, and gave us the ability to manage a large virtual infrastructure while reducing costs. The virtualization solution from Citrix offers more than other solutions had. Citrix is the best!

Scalability

Citrix Hypervisor

Citrix Hypervisor 6.4
Based on 1 answer
The servers latest versions have made massive improvements to scalability. But from past experience there have been issues when running workloads for extended periods of time without reboot on the hosts. I would need to run similar workloads on the 6.5 release which has changed much of the bottlenecks or issues so I'd imagine its far more capable now, Perhaps able to stand near the best in the market.

Return on Investment

Citrix Hypervisor

  • We noticed a true ROI within the first 2 years of implementation. The longer hardware refresh cycles save organizations like ours a lot of money each year.
Scott McGee | TrustRadius Reviewer

Oracle VM Server

  • Extremely satisfied with the product, it's still developing everyday and we are happy with its progress so far.
  • It does its job in a very easy to use and reliable fashion.
  • Looking forward to the new updates and what help it can bring to our current issues.
