7.3.46 OSA-Express4S 1000BASE-T Ethernet

OSA-Express4S 1000BASE-T Ethernet
The
drawer. Each feature has one PCIe adapter and two ports. The two ports share a CHPID,
which is defined as OSC, OSD, OSE, OSM, or OSN. The ports can be defined as a spanned
channel, and can be shared among LPARs and across logical channel subsystems. The OSM
CHPID type was introduced with z196. For more information, see 7.3.49, "Intranode
management network" on page 274.
Each adapter can be configured in the following modes:
QDIO mode, with CHPID types OSD and OSN
Non-QDIO mode, with CHPID type OSE
Local 3270 emulation mode, including OSA-ICC, with CHPID type OSC:
– OSA-ICC (OSC Channel) supports Secure Sockets Layer on z13s and z13 Driver 27
servers
– Up to 48 secure sessions per CHPID (the overall maximum of 120 connections is
unchanged)
Ensemble management, with CHPID type OSM
Operating system support is required to recognize and use the second port on the
OSA-Express4S 1000BASE-T feature. Table 7-43 lists the minimum support requirements for
OSA-Express4S 1000BASE-T.
