VMware vSAN RAID 5

vSAN is one of the fundamental building blocks for the implementation of an efficient HCI (Hyperconverged Infrastructure). For companies, vSAN represents an invaluable advantage because it allows them to have permanent control over the costs related to the information system, and to be more agile and reactive when solving a problem. Based on the Raid 5 architecture (Redundant Array of Independent Disks) and the principles of "erasure coding" and "failure to tolerate = 1" to protect data, vSAN improves security while saving money. the storage volume: each virtualized object is divided into four components, including one called parity, thus making it possible to find the missing data in the event of loss of one of the components.

In summary, vSAN enables the management and centralization of storage resources for all virtual workloads. The agility and flexibility offered by this solution greatly facilitates the implementation and evolution of all types of IT projects. The TCO (Total Cost of Ownership) is fully controlled and allows a reduction of up to 50% compared to other storage solutions.

How does vSAN work?

Agility and flexibility

With a growing need for agility and flexibility in companies, it was necessary to build a new approach to the Cloud. Indeed, the public cloud long sought for its benefits in terms of resource optimization and agility has shown its limits in some cases. It is the same for the private cloud, often necessary for governance issues or risk limitations.


To overcome the limits of these two technologies, the hybrid cloud is emerging. This combines the advantages of a public cloud with the security of a private cloud. This multi-cloud model is very popular in business today and appears to be the next step in professional computing.

Resources on demand

Concretely, vSAN allows companies to better size their resources and to be much more reactive when it comes to launching or developing new projects. Thus, IT teams can provision resources on-demand automatically. This ensures consistency of performance and optimizes support or maintenance times.

What functionalities and what characteristics

Your data is protected

As VMware is an extremely resilient solution, data risks are by definition very limited. The data is distributed over several VMs (RAID 5 architecture), guaranteeing a division of virtualized objects into 4 distinct components, including a so-called parity one, and thus making it possible to find missing data in the event of loss of one of the components.

An infrastructure designed to control your expenses

The infrastructure is designed to continuously optimize costs. The cost of storage is often one of the biggest expenses. The centralization of storage resources, therefore, allows better control, because of the often very significant growth in the volume of data to be backed up.

Dynamic space reclamation

To minimize unused resources, vSAN can dynamically reduce the resources used for application storage. Thus, space reclamation is automated to maximize performance.

A controlled total cost of ownership (TCO)

vSAN uses RAID protection, caching to achieve a high level of protection. Thus, this technology will provide you with simplified and secure protection VM by VM. And this with a cost reduced by half on average compared to a conventional solution.
