vSAN is VMware Hyper-Converged Infrastructure Software for providing software-defined storage infrastructure with high performance and lower cost compare to storage arrays.
vSAN can be configured by administrators on compatible hardware such as new servers or their old servers. Old servers are suitable for design and implementing vSAN infrastructure but if you have to expand your vSAN capacity, actually old servers are not prefect choice because of some limitations such as previous purpose and hardware in compatibility.
vSAN ReadyNode are x86 servers, available from all the leading server vendors, that have been pre-configured, tested and certified for VMware Hyper-Converged Infrastructure Software. Each ReadyNodes is optimally configured for vSAN with the required amount of CPU, memory, network, I/O controllers and storage (SSDs, HDDs or flash devices).
Some ReadyNodes are available with additional options aimed at simplifying purchasing, deployment, and support. These options are only available for select server vendors and ReadyNodes models:
- Pre-installed Hyper-Converged Infrastructure Software
- Bundled Hyper-Converged Infrastructure Software licenses
- Single vendor support from the server vendor to cover both hardware and Hyper-Converged Infrastructure Software
VMware provides an online tool for configuring ReadyNode, the online tool called vSAN ReadyNode Configurator.

- AF-4 Series
