• Virtual Storage Area Network (vSAN)

• Clustered Storage / Software Defined Storage (SDS):

  • Ceph

What is SDS? Software-defined storage is an approach to data management in which data storage resources are abstracted from the underlying physical storage hardware and are therefore more flexible.
