Is snapmirror relations ship possible between All san array(A700) and Fas( fas8200) ?
Yes, it's the OS that matters for SnapMirror functionality. Both A700 and FAS runs ONTAP.
You need to make sure 'Compatible ONTAP versions for SnapMirror relationships' between the two systems.https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.pow-dap%2FGUID-0810D764-4CEA-4683-8280-032433B1886B.html
