Since EMC Unity is a glorified VNXe, and uses the uemcli.exe , if you would like to see Unity inside OCI, try creating a VNXe datasource pointed against your Unity array. Make sure you have the latest uemcli.exe appropriate for Unity installed.
March 17th - For customer running OCI 7.2.x, we have a patch available for our EMC VNXe datasource that:
Solves various Unity parsing bugs
Add FC(oE) support for VNXe and Unity arrays - see storage ports, volume mapping and masking such that OCI server can properly calculate paths
Report Storage Pool compression on Unity
