There has been a debate about the two terms bare-metal storage and hypervisor, which one is better than the other. This article is going to clarify the difference between the two by explaining what are these terms and then will include some insight about which one is better than the other if that is the case at all.

What Is a Bare-metal Storage Server?

This is a new terminology give to the dedicated server we have been familiar with or a long time now. A bare-metal storage server, therefore, is the one that is only dedicated to one tenant, and no one else uses it. That is the concept of the bare-metal server that does not allow more than one tenant to share any kind of resources in the storage environment.

It not only gives peace of mind to the tenant but also offers some physical benefits like more data security as no one is sharing anything, and there is also no noisy neighborhood problem. in this way, a bare-metal storage environment has a special and dedicated arrangement and deployment of resources which suit the single tenant in a  more customized and favorable manner.

What are Hypervisors then?

The hypervisor is a term that is related to the cloud storage environment. A hypervisor is basically a kind of operating system which can run on a bare-metal storage server. The main function or purpose of a hypervisor is to create virtual machines to offer virtualization to the storage infrastructure.

When an enterprise gets bare-metal storage that has a hypervisor installed, the applications and programs can run on virtual machines instead of on the server natively. The applications are not directly run on the server but on the virtual machines created by the hypervisor.

How to Decide Between the Two

The bare-metal storage server is a dedicated single-tenant storage environment with no virtualization, and on the other hand, a hypervisor allows the user to enjoy the advantages of virtualization through running the applications on the virtual machines and not on the server, to offer more flexibility. Deciding between the two would depend on what a user needs, a dedicated server or a cloud computing facility that is enabled by installing a hypervisor. If virtualization is not needed and resources are not meant to be shared with anyone, bare-metal storage is the right choice.


Having reinforced the differences between bare-metal storage and hypervisor, decision making must be easier and correct. Of course, the decision has to be aligned with the enterprise’s needs and requirements which are meant to be met.
