Server-side processing

I read 100 data from Database, but I send only 10 data to DataTable. But I want use Server-side processing from http://www.datatables.net/usage/server-side.

My code is:

function prepareDataTable() {
$('#displayData').dataTable({
	"iDisplayLength": 10,
	"iDisplayStart": 20,
    "aaData": Rows,
    "iTotalRecords": 57,
    "iTotalDisplayRecords": 57,
    "bSort": false,
    "bFilter": false,
    "aoColumns": [
        { "mDataProp": "name" }
    ]
});

In Rows I have only 10 data. So I want use Ajax to pass next data. And I want:

1. I want display "Showing 1 to 10 of iTotalRecords entries", where iTotalRecords is number of all my data.
2. Arrows next / previous will be enable (now are disable)
