Chose XenServer
VMware requires an Enterprise Plus license to use GPU's, which is more expensive.
In the scheme of the real world, Citrix Hypervisor is used much less than the other two main competing products; MS Hyper-V and VMWare vSphere. So, choosing Citrix Hypervisor for your organization comes down to whether you are comfortable going with a lesser-used product. All …
VMware seems to be the standard and is more widely accepted. However, Citrix Hypervisor, is easily learned and cheaper. We have also used VirtualBox to offer up ideas for other free products. VirtualBox seems to be easier for end users who just want simple VMs and not …
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 …
Because we utilize Citrix for our VDI this solution made the most sense moving forward. Citrix Hypervisor was designed to work with Citrix VDI solutions out of the box.
Feature for feature they are neck and neck. I have used Hyper-V 2012 and 2016, VMware ESXi and XenServer evenly. XenServer is a fast install, good documentation, with enterprise features out the box that compare or exceed what VMWare offered with a higher cost of entry.
There are other hypervisors that are more eficient than Xenserver, but it is necessary to spend some money to buy them. If your demand is to compute processing, Xenserver permits you to create good environments to do this. If you need to integrate the hypervisor with other …
I used vSphere (and vCenter server), Hyper-V, and XenServer to teach a virtualization class. vSphere is certainly the leader among these three, and Hyper-V is second (but not far behind). XenServer is third, which lacks many advanced features provided by vSphere and Hyper-V.
XenServer like the similar product I've used in the hypervisor market stacks up well in regards to compatibility with virtual machine [operating systems]. It is also capable of allowing for large, powerful VMs to be run upon it. The main selection of XenServer in environments …
XenServer is easier to use and cheaper than VMWare, but there is a bit less industry support. If your aren't afraid to use products from someone besides the market leader, XenServer is a great alternative to VMWare.
It can be really helpful & useful if we are using Citrix Hypervisor with other provisioning tools. Here are some specific scenarios where Citrix Hypervisor (formerly Citrix XenServer) is well-suited: Server Consolidation, Virtual Desktops, Disaster Recovery, Development & Testing Environments. On the other hand, there are some scenarios where Citrix Hypervisor may be less appropriate: Small-scale Deployments, Highly Heterogeneous Environments, and Limited Virtualization Requirements.
Adding or presenting additional storage to the host can often be a task that is far more involved than competitive products.
The product can require reboots more frequently than competitors due to the DOM kernel getting "hung up".
Sometimes when a virtual machine is deleted it still leaves behind orphaned vdisks.
Recovering from the loss of a host can sometimes cause virtual machines to require lengthy command prompt scripting to fix so they can be powered back on from another host.
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.
XenServer is a good product in its use and probably free if you have the right Citrix licenses already. However, it does require specific knowledge to manage, which makes it harder to manage if you don't have that knowledge in house.
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.
The staff I've worked with are very knowledgeable or able to get a very well articulated and capable support team member on the phone or helping them if necessary and they always want to ensure the best experience possible for you on the platform. The ability for the support team to reach out to hardware vendors for assistance is a nice plus too.
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.
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.

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.
Xenserver is easy to learn. We paid for support only for installation and deployment in the first three years, and now our team has the knowledge to solve most problems.
Low CAPEX if you have a team that uses open source software day by day.
But paid support is necessary to solve critical problems. The open source community is not enough. Actually, we have difficulty solving some bugs without paying for support.
Medium OPEX if you have a team that uses open source software day by day.
