Array-based storage

VxRail dynamic nodes support Dell storage arrays such as Dell PowerStore, Dell PowerMax, Dell PowerFlex, and Dell Unity XT. These storage arrays support several storage protocols, such as FC, iSCSI, NFS, and NVMe. These arrays support LUNs, vVols, and NFS storage types.

For more information about requirements and the supported storage types on various arrays, see Dell VxRail 8.0.x Support Matrix and Dell VxRail 7.0.x Support Matrix.
