Review: Citrix Hypervisor Consolidates Multiple Virtual Machines on a Physical Server

This virtualization application helps healthcare organizations make the most of their data center infrastructure.

Carlos Soto is an award-winning reviewer and journalist with 20 years of experience covering technology and business.

Healthcare organizations should harness the full benefit of their data centers to bolster patient services using transformative technology. For that to happen, CIOs and CTOs must analyze, integrate and optimize their current and planned use of data virtualization solutions.

By virtualization, I mean solutions that empower IT data centers to run multiple independent computing sessions simultaneously on a single physical computer. By enabling one system to support or host multiple guest virtual machines, healthcare organizations are essentially sharing hardware resources. Health systems that virtualize powerful servers can reduce the total cost of ownership for every server they run.

How can healthcare organizations achieve this ambitious goal?

The Citrix Hypervisor Features Resource Improvements

Citrix offers the widest variety of graphics processing unit pass-through options as well as virtualized GPUs. These let virtual machines access physical GPUs installed on host machines for improved performance.

Citrix Hypervisor helps healthcare organizations of any size consolidate and transform computing resources into virtual workloads, improving data center capabilities. A recent look at the Citrix Hypervisor left me impressed by the platform’s features and capabilities. It would well serve CIOs looking for cost-effective desktop, server and cloud virtualization infrastructures. Specifically, this solution cuts costs while improving the utilization rates of existing hardware resources.

The most effective feature I observed was Citrix Hypervisor’s ability to consolidate multiple virtual machines onto a physical server, a key component of data center optimization for healthcare organizations. This also reduces the number of separate disk images that IT staff need to manage. The process is not a simple one, but Citrix Hypervisor allows even less experienced IT professionals ] initiate the transformations and monitor the enterprise once that task is completed.

Why the Citrix Hypervisor 8.2 Requires a Fresh Start

Citrix Hypervisor 8.2 must be installed fresh; there is no direct path for an upgrade from previous versions. As such, healthcare organizations are advised to start from scratch with the process, which Citrix thankfully makes fairly easy.

Once I performed the installation, this latest iteration easily integrated with the existing networking and storage infrastructures in my test bed. It also scheduled maintenance with zero downtime because it migrates virtual machines between Citrix Hypervisor hosts in real time.

Cutting-edge data architectures, such as data mesh and composable applications, may be the future of healthcare data centers. But virtualization capabilities from solutions such as Citrix Hypervisor will help drive those modernization efforts forward.

How Citrix Hypervisor Can Benefit Healthcare

Citrix Hypervisor empowers organizations to run many segregated virtual sessions on a single physical computer, and all software programs executed on these virtual machines are separated from the hardware that powers the virtual machine sessions. Therefore, health systems that create Citrix-based virtual machines can use these small environments to speed up software development and more affordably control and protect the production environment.

Citrix Hypervisor removes the risk and tedium involved in regularly buying and setting up new computers.

In the past, I have had DevOps teams build applications for Apple environments — even though our native enterprise is all Microsoft — to determine how to best roll out internal resources to both macOS and Windows clients. This cross-platform integration is immensely helpful in highly regulated areas such as healthcare, where downtime is not an option.

Citrix Hypervisor is powerful because it is based on the Xen Project hypervisor, a Type 1, bare-metal hypervisor, which means Citrix runs directly on the physical hardware of the host machine (as opposed to a Type 2 hypervisor, which runs on top of an existing operating system).

Healthcare organizations should primarily choose such Type 1 systems for strong security and simplified administration.

Type 1 hypervisors bring the ability to securely isolate virtual machine builds between virtual machines, securing the boot as a separate process. This provides extremely safe remote management. The centralized security policies are also better, which ensures that there is no unauthorized access through a more robust and easily managed set of permissions.

The management of Type 1 hypervisors is also much easier. Citrix Hypervisor offers centralized management capabilities that enable agencies to better control and monitor the entire virtual infrastructure at scale from a centralized management console. There is not much difference between managing a few systems and watching over hundreds of them using this method, so healthcare organizations can scale up in response to increasing needs without worrying about endangering their cybersecurity.
