==Non-IBM SNA implementations==
Non-IBM SNA software allowed systems other than IBM's to communicate with IBM's mainframes and [[AS/400]] midrange computers using the SNA protocols.

Some Unix system vendors, such as [[Sun Microsystems]] with its SunLink SNA product line, including PU2.1 Server,<ref>{{cite book |title=SunLink SNA 9.1 PU2.1 Server Configuration Guide |publisher=[[Sun Microsystems]] |date=1997 |url=https://docs.oracle.com/cd/E19246-01/802-2673/802-2673.pdf}}</ref> and [[Hewlett-Packard]]/[[Hewlett Packard Enterprise]], with their SNAplus2 product,<ref>{{cite web |title=HP-UX SNAplus2 Software - Overview |website=[[Hewlett Packard Enterprise |HPE]] support |url=https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c02923531}}</ref> provided SNA software.

[[Microsoft]] introduced SNA Server for [[Windows]] in 1993;<ref>{{cite magazine |title=Microsoft, Novell, IBM target host-to-LAN links |first1=Shawn |last1=Willett |first2=Jayne |last2=Wilson |magazine=[[InfoWorld]] |volume=15 |issue=47 |page=39 |date=November 22, 1993 |url=https://books.google.com/books?id=ATsEAAAAMBAJ&pg=PA39}}</ref> it is now named [[Microsoft Host Integration Server]].

Hewlett-Packard offered SNA Server and SNA Access for its [[HP 3000]] systems.<ref>{{cite magazine |title=Software offerings accompany Spectrum announcement |magazine=[[Computerworld]] |volume=20 |issue=9 |page=10 |quote=HP also unveiled IBM connection capabilities with Systems Network Architecture (SNA) Server and Server Access software. |date=March 3, 1986 |url=https://books.google.com/books?id=NeEyLTmpL_EC&pg=PA10}}</ref>
