ES Connect
HP to IBM
To send information to its counterpart on IBM, BCOM on the HP computer interfaces
with SNAX. SNAX is in session with the Virtual Telecommunications Access Method
(VTAM) on the IBM mainframe via the Windows NT platform. SNAX does not send the
data directly; it uses the services of Titanium to provide a high-speed link between
NonStop S-Series servers and Windows NT workstations.
ES Connect running on the NT platform receives all traffic from SNAX via Titanium and
forwards the traffic to the appropriate VTAM session using a peripheral component
interconnect (PCI) to ESCON card.
VTAM hands off the information to the BCOM application running on the IBM
mainframe.
