What Is a Hypervisor?

Scale Up Scale Out-title

Do you ever find yourself asking the question, what is a hypervisor? It may sound like technical jargon, but understanding what it means can greatly benefit your business. A hypervisor is essentially software that allows multiple virtual machines to run on a single physical machine. This technology has become increasingly popular in recent years due to its ability to optimize resources and reduce costs for businesses. In this white paper, we will delve into the world of hypervisors, discussing their different types, benefits, and drawbacks, and how to choose the right one for your needs. So, get ready to dive into the fascinating world of hyperconverged storage.

What Is a Hypervisor?

A hypervisor, also known as a virtual machine monitor (VMM), is software that enables multiple operating systems to run on a single physical machine. It works by creating and managing virtual machines (VMs) that share the host system’s resources.

Hypervisors allow businesses to consolidate their infrastructure by running multiple VMs on one physical machine. This can lead to cost savings through reduced power and cooling costs while still providing flexibility in deploying different applications across multiple environments.

The Different Types of Hypervisors

There are two types of hypervisors: Type 1, which runs directly on top of the physical hardware, and Type 2, which runs within an operating system.

Type 1 hypervisors are often referred to as “bare metal” or “native” because they have direct access to the server’s physical resources without any additional layers in between. This allows for better performance and security since other programs have less potential for interference.

Type 2 hypervisors, on the other hand, run within an existing operating system like Windows or Linux. They rely on this underlying OS to manage hardware resources such as memory and CPU time.

Type 1 & Type 2

Type 1 | These hypervisors run directly on the host’s hardware without requiring a host operating system. This type is typically used in enterprise data centers and cloud environments due to its high performance and security features.

Type 2 | These hypervisors run within an existing operating system as an application. These are often used by individuals or small businesses for testing purposes, running multiple operating systems on a single machine, or accessing legacy software.

Another type of hypervisor is the embedded hypervisor which is pre-installed on hardware devices such as servers or storage arrays. It allows for more efficient use of resources while reducing complexity compared to installing additional software.

When choosing a hypervisor, it’s important to consider factors such as scalability, security requirements, management tools available, and compatibility with your IT environment.

Clustering Hypervisors

When it comes to business continuity and high availability, clustering hypervisors can be a game-changer. By grouping multiple hypervisors together into a cluster, businesses can achieve redundancy and failover capabilities that ensure uninterrupted service even if one or more of their servers experience downtime due to hardware failure or maintenance needs.

With clustering technology, workloads can automatically migrate from one node to another within the cluster without any disruption in service delivery. This approach not only provides better uptime but also enhances disaster recovery preparedness by reducing single points of failure across distributed data centers where these clusters are deployed.

Clustering hypervisors for redundancy and high availability requires proper planning, design considerations, and ongoing management practices but offers significant benefits for organizations looking for reliable IT services with minimal interruptions.

The Benefits of Using Nfina’s Hypervisor

Using Nfina’s hypervisor has numerous benefits that make it an attractive option for businesses and individuals alike. One of the primary advantages is virtualization, which allows multiple operating systems to run on a single physical server. This not only saves space but also reduces hardware costs as fewer servers are needed.

Another benefit of using Nfina’s hypervisor is enhanced security. By isolating each virtual machine from one other, any potential security breaches or malware attacks can be contained within the affected VM, without affecting the other machines running on the server.

Nfina’s hypervisors also provide greater flexibility in managing resources such as CPU, memory, and storage, making it easier to allocate resources where they are most needed at any given time. Additionally, this flexibility enables easy scalability by allowing users to add new VMs quickly and easily when required.

Furthermore, using a Nfina’s hypervisor can improve disaster recovery capabilities by simplifying backups and enabling quick restoration of services after an outage or failure occurs.

These benefits demonstrate why using Nfina’s hypervisor can be advantageous for businesses looking to optimize their IT infrastructure while minimizing associated costs and risks.

The Drawbacks

An issue with hypervisors is that they require significant resources to function properly. This means that you may need to invest in more powerful hardware or allocate additional resources from your existing infrastructure to ensure optimal performance.

In addition, managing multiple virtual machines can potentially become complex and time-consuming without proper planning and organization. It’s important to have a solid understanding of how each VM interacts with others on the same host, as well as any potential conflicts or compatibility issues between different VMs.

Licensing costs can also be a concern when it comes to using hypervisors. Depending on your needs and budget, you may need to purchase licenses for both the hypervisor software itself as well as any guest operating systems running within it.

While there are certainly drawbacks associated with using hypervisors, these challenges can often be mitigated through careful planning and management practices. By taking steps like implementing strong security protocols, investing in adequate hardware resources, and maintaining good organization habits when working with multiple VMs, organizations can enjoy many benefits of virtualization without experiencing too much negative impact on their day-to-day operations.

How to Choose the Right Hypervisor for your Needs

When it comes to choosing the right hypervisor for your needs, there are several factors that you should consider. First and foremost, you need to determine what type of virtualization technology you require.

Type 1 hypervisors run directly on a host machine’s hardware, while Type 2 hypervisors run as an application on top of an existing operating system. If you’re running critical workloads or need high-performance virtualization capabilities, then a Type 1 hypervisor is likely the best choice.

Next, consider the scalability and flexibility of the hypervisor. Can it handle expanding workloads? Is it compatible with different hardware configurations? These questions will help guide your decision-making process.

It’s also important to look at cost considerations such as licensing fees and ongoing support costs. Some popular operating system options like VMware® ESXi, Microsoft® Hyper-V, Red Hat™ (IBM®) KVM, or Citrix® Hypervisor can be expensive in terms of upfront costs but offer robust features that may be worth the investment.

Consider any unique requirements specific to your business needs such as compliance regulations or integrations with other software solutions.

Selecting the right hypervisor requires careful consideration of various technical and financial factors specific to each individual organization’s needs.


Nfina’s hypervisor is an essential tool for any organization looking to optimize its IT infrastructure by enabling virtualization. With its ability to create multiple virtual machines on a single physical server, it allows businesses to save time and money while increasing efficiency.

When choosing the right hypervisor for your needs, it’s important to consider factors such as scalability, compatibility with existing systems, ease of use, security features, and cost-effectiveness.
