Number of connection through iSCSI to Microsoft server 2008 R2

I am having trouble of founding numbers that indicate number of available connections through iSCSI to Microsoft server 2008 R2WITHOUT license while using one node.

http://support.microsoft.com/kb/2535811
Link above gave lots of information about the amount connection that can be maintained through iSCSI to server 2008 R2, but I am quite sure that this are only when every connection has proper license for Microsoft server 2008 R2.

So if anyone has ideas to help me with my question throw me with some information, because I haven't been able to google or find proper answer anywhere to this question.

Thank you all!
