We are using VDI infrastructure which is hosted on Citrix XenServer. All of our Virtual Desktop environments are being created and managed on Citrix hypervisors. The business problems it addresses: Server Consolidation, Flexibility & Scalability, Disaster Recovery, Cost Reduction, etc. The scope of the use case may vary depending on the organization's specific requirements. It can range from small-scale deployments for individual departments or teams to large-scale enterprise deployments spanning multiple data centers.
  • Host Virtual Desktops.
  • Application Virtualization is much easier.
  • Scalability & Flexibility.
  • Resource pools are not reliable.
  • No provision for automated desktop creation.
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.

We use Citrix Hypervisor to stand up virtual servers based on a single piece of hardware. It allows us to get the maximum benefit from the hardware by parsing out its resources across several different virtual servers saving us money in licensing, hardware needs, and power needs in our data center.
  • Citrix hypervisor does price very well for small organizations. It is free.
  • Since this product is open source it does not have any type of vendor lockdown issues.
  • Allows live migration of VM's so you can keep systems up and running when changes are needed to the hardware in the background.
  • The GUI management tools are quite easy to learn.
  • Has Snapshot capability which is a great way to protect against malware as well as do risk-free upgrades.
  • Although part of this is free the free solution has limitations that make the purchase of the paid version a requirement for most medium and large enterprises.
  • Support for USB devices is lacking vs. its competitors.
  • Technical support is somewhat limited especially the free "Google browsing" type since the product is used much less vs. Hyper-V or VMWARE.
  • In a related issue to tech support, finding local IT support who have used the product is also challenging.
  • Networking/virtual networks are less stable than they should be.
The free version is a boon for small businesses that want to have a hypervisor but not the headaches of using something that requires licensing. It is more than adequate to compete with the lesser versions of Hyper-V or VMware. Any small business that wants to lessen its hardware footprint could benefit from this product. If you are a medium or large business it is also a nice addition to the cupboard if you already use other Citrix products and are familiar with the Citrix support process. Shops that are fully committed to VMWare or MS Hyper-V should probably avoid this as it would just act to dilute your system and add unneeded complexity. Citrix Hypervisor is not most common Hardware Hypervisor on the market but it is more than competent for most Enterprise Deployments.

We use Citrix Hypervisor as one of our virtualization tools. The ability to run multiple VMs on each physical server has been beneficial. As one of the leading virtualization management platforms, it offers many great features out of the box. The ability to quickly set up and configure and easily managed environment are among a few of the positives. It's not the most robust and feature packed, but it's cheap and relatively simple to use.
  • Creating VMS - virtualizing physical or already virtual images is a snap
  • Configuration - in a smaller environment, configuration is simple and easy to understand
  • Templates and Clones - the ability to create these on the fly make it great for a dev environment
  • 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
Citrix Hypervisor is well suited for quickly standing up a virtualized environment. As the environment scales, there is less efficiency within the platform, however. The partnership with Microsoft seems strong, but that also limits the product in the end. If other partnerships were as in depth as Citrix with MS products, it would greatly enhance the overall score. I would not recommend this product if you need to virtualize a large, complex system.

Citrix Hypervisor is a perfect virtualization solution which allows many functions, among which scalability has the main function. The architecture offers a combination of remote desktop services and web interface servers. Implementation and change management are complex. The cost is very good. The project requires long term vision and lots of planning. Also, you need a good team to implement such a big project.
  • Good scalability.
  • The ease of setup.
  • Very good integration with other tools.
  • The support from the vendor is very good.
  • The interface can be more user-friendly.
  • Model the management of clustering.
  • Use DDK to compile drivers.
Virtualization of all infrastructures helps us to manage well our resources. Load balancing helps us to assure great availability and be compliant with business continuity indicators. Also, the solution offers great security and allows for rapid provisioning and flexible hardware utilization. It solves our problem by allowing users to connect to their machine at work no matter where they are currently.

We utilize Citrix Hypervisor as our sole hypervisor in our entire Citrix environment. This has helped us reduce our hardware expenses by over 75% with virtualizing all of our production servers. We were on a 3 year replacement plan when we had physical production servers but now we get 5-7 years on our hypervisor servers. Because it's an existing Citrix product we do not have to work with multiple vendors if there is ever a software issue.
  • The install is incredibly easy. Even version upgrades require minimal effort to accomplish.
  • The dynamic storage capabilities are great. If a server runs low on disk space we can increase the drive space in minutes instead of waiting days for new drives to arrive and the time to physically shut down the server to add them.
  • A lot of software vendors only support VMWare and Hyper-V as acceptable hypervisors for their products.
  • It lacks the ability to truly upscale memory in a live environment.
It's extremely easy to install, use, and maintain. They offer a free hypervisor that has a lot of great features that are only found with paid versions of competitors products. If you are using Citrix for your VDI solution you can compliment things with a Citrix hypervisor.

Our organization utilized XenServer to replace VMware ESXi. We have consolidated all physical servers to just 3 hypervisors and manage the environment with XoA. We currently have 30 VMs running in our infrastructure. We utilize Windows 2016 and 2012 R2 along with a few instances of Linux. Each department uses an individual server which has improved the speed and delivery of IT services to our staff.
  • Resource Monitoring is a good and I am able to monitor my entire infrastructure whether I'm using my iPhone remotely or while on any company-issued laptop to ensure our services run at peak efficiency.
  • CLI - the command line is not hard to use. It can take a little time to get used to the commands but once you have them down managing the environment from the GUI or CLI is pretty easy.
  • Backups are very easy to start and manage with XenCenter or XoA. Keeping business DR scenarios achievable.
  • Better support for USB devices (which is a weak point of most Hypervisors)
  • More native iPhone/Android apps to monitor the environment
  • Better reports for an insight of how healthy the environment is
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.

XenServer is used for the whole organisation and hosts all the companies VM's. It is very helpful to manage and troubleshoot all existing servers. It provides capabilities to monitor all servers. Creating new VM's using XenServer is seemingly very easy for the process is straight forward and one can easily follow through.
  • Provides visibility of all the VM's and one can tell when any of the server's are offline.
  • The functionality to re-boot a VM is easy and quick
  • It is secure and can be accessed remotely.
  • Disaster recovery is difficult to use
For a company that has multiple servers with limited technical support. Xenserver can easily be supported remotely.

We are using Xenserver as the principal hypervisor of our private cloud that offers infrastructure as a service to the academic community of the University of Sao Paulo and other public institutes of Brazil. This private cloud has 480 servers (9800 CPUs, 5TB RAM, 15PB storage) and it is used for scientific processing and many other services like web services, email systems, a social collaboration systems.
  • Free advanced resources: Live migration, live storage migration, snapshots, open switch/vxlan. Others hypervisors offer the same but are paid.
  • It is fully compatible with CloudStack and OpenStack.
  • Supports paravirtualization (PVM) and hardware virtual machines (HVM).
  • It is open-source and easy to troubleshoot.
  • The snapshots management still presents problems, especially in environments with several virtual machines.
  • The virtual memory management is still weak if compared with other hypervisors.
  • There isn't a central server for the management of physical hosts. XenCenter is a client that is not good because it demands so much memory and CPU to execute simple tasks in environments with several VMs.
Xenserver is a great hypervisor, with advanced features, open-source and free. This is possible by support from Citrix. It works perfectly in cloud environments and standalone systems. If you need to create an environment to execute virtual machines to scientific processing, XenServer is well suited. However, we are having difficulty managing environments that demand high disk I/O and net I/O too. In this case, Hyper-V and ESxi work better.

XenServer is one of the products used for teaching a virtualization class.
  • Create virtual machine
  • Xenmotion
  • Config/installation of XenServer
  • Lacks management tool equivalent to vCenter server. XenCenter is a client-side app only.
  • Lack official support for work load balancing (the support has been dropped)
XenServer is suited for simple, introduction to virtualization or virtual machines.

The XenServer workloads I have set up and currently provide are primarily for clients. These workloads cover anything from an IT lab, VDI and Server workloads for the entire data center. It is a mixed use hypervisor in most environments where it is placed for a purpose (such as VDI) at a cost savings and management supplement due to its ease of use.
  • 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
  • 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.
I feel XenServer is well suited for VDI based workloads at least within the Citrix product portfolio as it is extremely easy to set up and manage. It is also a reasonably well suited platform for smaller data centers which require less complexity and monitoring. Workloads requiring the usage of shared GPU are well suited for XenServer.

The product is less well suited for large enterprise data centers. However, new versions are bringing features to allow the hypervisor to contend. Complex virtual networking environments may not be well suited for XenServer.

We are using XenServer for all our virtualization of servers company-wide. It allows us to leverage our hardware and run multiple VMs on each physical server.
  • Low cost. Support is much cheaper than the alternatives.
  • Much simpler to implement and manage than other hypervisors.
  • Good performance on all the VMs.
  • Front line support form off shore has been challenging lately. Need a better escalation path for issues.
  • Upgrades can be difficult at times. Not always super smooth.
If you have the money to throw at the best-of-breed it may be better to go with VMWare. Its more widely used.
