What Is Xen Project?

Xen Project is a sort of a dark horse among other hypervisor options available on the market. Xen Project Hypervisor is a product that comes as an open-source bare-metal hypervisor. Xen is distributed as part of the Linux Foundation, which includes various technological contributors. Xen Hypervisor has taken a different path in terms of catering to customer needs and target audience. Currently, Xen Project seems to focus on imbuing its Xen Hypervisor with features that are largely beneficial for edge deployments and their smooth integration into centralized management. Xen also devotes much attention to containers.

Being a type-1 hypervisor, Xen Hypervisor can run several instances of a single operating system (OS) or even a multitude of OS in parallel on a single host. Xen Project can be the foundation for various applications, like IaaS, desktop virtualization, hardware appliances, server virtualization, security application, containerization, automotive, and such. Because of its specificity, Xen Project may seem like the odd one among the plethora of other hypervisor offers, like VMware ESXi, Microsoft Hyper-V, AppliDis Fusion, or others. Nonetheless, Xen is worth checking out for several reasons discussed below.

Xen Project Features
& Benefits

Unlike other hypervisor vendors, Xen Project is open-source, which lends to its unusual set of features and ongoing growth thanks to the zeal of its community members. Some Xen features, obviously, will be similar to other hypervisors while others will stand out as specific to the project.

Xen Project Features:

  • Multiple Operating System Support. You can choose any which one or several OS (Windows, Linux, NetBSD, or FreeBSD) at the same time and run them in the manner that is most favorable to you.
  • Multiple Cloud Support. Xen Project allows you to bounce back-and-forth between your preferred public cloud providers as cloud technology progresses, further enhancing your IT environment versatility.
  • Virtual Machine Migration. Xen Hypervisor enables live migration providing a better grasp on the workload intensity on your host servers and redistributing resources for most optimized work.
  • Multiple Vendor Support. Xen is certified and supported by various software and service vendors, which makes the configuration and support of your IT infrastructure safer and more accessible.
  • Open Source. Not only does Xen Project free up limitations on participating in the code, but there is also less anxiety about it being dropped as it will go on as long as there is a community that favors it.
  • Modularity. Xen provides for control domain functionality to be run in Linux subdomains or other smaller domains with minimal kernel and driver, reducing threat surface and distributing bottlenecks.
  • Xen Hypervisor is a consumer-centric offer where the product has been created for the user, the user invests in its developments, and the user can tweak it to match its specific demands. Such circumstances make Xen a perfect fit for deployments of any size but particularly for edge hosts in a larger network that has unconventional requirements.

Xen Project Benefits:

  • Expanded Scalability. Not only is scalability impacted by the off-limits multi-vendor and multi-platform support, but Xen Hypervisor can be scaled to as many as 4,095 host CPUs with 16Tb of RAM.
  • Enhanced Security. Xen Project is highly regarded for its security because of its architecture, leading security disclosure policies, and progressive security features (Live Patching, KCONFIG, VM Inspection).
  • Ultimate Flexibility. Xen is considered to have the most flexible hypervisor on the market as you can not only fit Xen into any hardware/software configuration but you can also build your products based on Xen.
  • Xen Project has a large ecosystem of software partners as well as it can use any type of virtualization on old and new hardware alike. Its modular architecture, security focus, and unrestricted flexibility make it perfect to tailor workload balance and inter-operation within large environments with edge instances. Additionally, Xen Project is suited for building products and services based on cloud, servers, embedded/automotive, and desktop offers with emphasis on security.

Xen Project and StarWind VSAN

To be able to actualize all of the ultra-power enclosed in the Xen Project hypervisor, you need high-performing and resilient storage. Xen Hypervisor gets chosen to govern a variety of infrastructures, from light to really heavy, complex ones. Most often, bulky and overly expensive NAS or SAN units won’t be suitable to provide Xen with the desired room for maneuvering. StarWind Virtual SAN (VSAN) is the perfect match for Xen Hypervisor: it’s a lightweight software-defined storage (SDS) solution, which allows enjoying high availability and fault tolerance starting with two nodes already (no witness required).

StarWind VSAN can be deployed as a Linux-based VM that is easy to operate, unlocks close to 100% of your underlying hardware potential, can work if you lose an entire node plus one disk, and can feature 24/7/365 ProActive Support that monitors your environment for any abnormal behavior and notifies StarWind engineers independently for them to take care of the concern. VSAN from StarWind, coupled with Xen Project, will take your entire virtualization and production experience to a whole new level.

What Is
StarWind VSAN?

StarWind Virtual SAN has been created explicitly to lower the TCO for Enterprise ROBO, SMB & Edge. Small deployment scenarios can now experience dramatic and visible elevation in how much they can get out of their seemingly limited IT resources. It’s an SDS that delivers high availability by mirroring internal hard disk and flash between hypervisor servers, creating a single fault-tolerant storage pool for seamless infrastructure performance. Any virtualization admin will be able to easily deploy, configure, monitor, and manage StarWind VSAN thanks to its user-friendliness.


StarWind VSAN merges your entire cluster (Xen hypervisor + any other hypervisor or non-hypervisor-managed) into a unified resilient environment. It allows utilizing all of the available IT resources to the fullest, enabling 100% out of your underlying storage capacity. All of your partitions, applications, and other workloads will be available and secure at all times.

Complete Versatility

StarWind VSAN serves as a robust virtual storage pool. After you’ve installed it on any of your clusters, your entire cluster becomes resistant to any disasters. There are no tricks: you buy a single solution that is integrable with any infrastructure configuration. It brings enterprise-level SDS features to businesses of any size and budgets.


StarWind VSAN offers unlimited scalability — up and out — with as many proprietary components as you need. Synchronous replication and compression provide maximum storage optimization and speed. You can upgrade or change your infrastructure compilation without any downtime at all. Data resiliency with the required Hardware or Software RAID is assured.

Simple to Use
and Cost-Efficient

Customers pay a flat fee and gain access to all features without any feature/socket restrictions. Licenses vary only by capacity. StarWind VSAN ensures constant uptime regardless of whether you’re all-flash or not. You don’t have to buy any additional GUIs or sift through CLI since StarWind VSAN comes with a neat unified web UI. TCO is significantly decreased, so you can focus your finances on other improvements.
