If you can figure out the table/column that holds the MxGUID, you can do something like this:
...R_Inventory.numberOfCPU,'https://yoursimserver:50000/mxportal/DevicePage/devicepage.jsp?nodeId='+ MxGUIDColumnName AS SMHPage
But it might be easier to just go directly the SMH URL if you can't figure out the MxGUID field:
...R_Inventory.numberOfCPU,'https://'+ R_Inventory.DeviceName +':2381'AS SMHPage
