The 40 Coolest Software-Defined Storage Vendors: The 2021 Storage 100

The 40 coolest software-defined storage vendors of the 2021 Storage 100 bring software capabilities, services and cloud connectivity to storage technology.

Storage arrays are no longer built around hardware.

Instead, it is the software that defines the services customers derive from their storage systems, software that may run on general-purpose hardware, in a virtual machine or container, or in the cloud.

Nearly all developers of storage systems are at heart software-defined storage developers. As part of CRN’s 2021 Storage 100, here are 40 of these companies.
