Yes
Details
Dell EMC allows mixing of different VxRail Appliance models within a cluster, except where doing so would create highly unbalanced performance. The first 4 cluster nodes do not have to be identical anymore (previous requirement). All G Series nodes within the same chassis must be identical. No mixing is allowed between hybrid and all-flash nodes within the same storage cluster. All nodes within the same cluster must run the same version of VxRail software.
