NON-QDIO operational mode

The OSA-Express 1000BASE-T Ethernet, Fast Ethernet and Token-Ring also support the non-QDIO mode of operation (CHPID type OSE). The adapter can only be set (via the CHPID type parameter) to one mode at a time. The non-QDIO mode does not provide the benefi ts of QDIO. However, this support includes native SNA/APPN, High Performance Routing, TCP/IP passthrough, and HPDT MPC. The new OSA-Express 1000BASE-T Ethernet provides support for TCP/IP and SNA/APPN/HPR up to 1 gigabit per second over the copper wiring infrastructure.

The same OSA-Express Token-Ring feature is supported on z990 and z900. This Token-Ring supports a range of speed including 4, 16 and 100 Mbps, and can operate in both QDIO and non-QDIO modes.

Note: OSA-Express 155 ATM and OSA-2 FDDI are no longer supported. If ATM or FDDI support are still required, a multiprotocol switch or router with the appropriate net-

Server to User connections

A key strength of OSA-Express and associated Commu- nications Server protocol support is the ability to accom- modate the customer’s attachment requirements, spanning combinations of TCP/IP and SNA applications and devices. Customers can use TCP/IP connections from the

remote site to either their TCP/IP or SNA applications on zSeries and S/390 by confi guring OSA-Express with QDIO and using either direct TCP/IP access or use appropriate SNA to IP integration technologies, such as TN3270 Server and Enterprise Extender for access to SNA applications. Customers who require the use of native SNA-based con- nections from the remote site can use a TCP/IP or SNA transport to the data center and then connect into zSeries and S/390 using appropriate SNA support on OSA- Express features confi gured in non-QDIO mode.
