7.3.43 OSA-Express5S 1000BASE-T Ethernet
The OSA-Express5S 1000BASE-T Ethernet feature is installed exclusively in the PCIe I/O
drawer. Each feature has one PCIe adapter and two ports. The two ports share a CHPID,
which can be 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.
– Designed to improve security of console operations.
– Up to 48 secure sessions per CHPID (the overall maximum of 120 connections
unchanged).
Ensemble management, with CHPID type OSM for dynamic I/O only.
