OSA-Express2 – Connectivity for LANs

Open Systems Adapter-Express2 (OSA-Express2) for connectivity to Local Area Networks (LANs), supports 1000BASE-T Ethernet, Gigabit Ethernet (GbE) LX and SX, and 10 GbE LR. The OSA-Express2 features are hot-pluggable, support the Multiple Image Facility (MIF) sharing of channels across logical partitions, and can be defined as a spanned channel to be shared among logical partitions within and across LCSSs

The maximum combined number of OSA-Express2 and OSA-Express features supported on the z9 BC per server is 24 (up to 48 ports) on the Model S07 while the Model R07 supports 15 features (30 ports). The maximum combined number of OSA-Express2 and OSA-Express features supported on the z9 EC per server is 24(up to 48 ports). OSA-Express2 and OSA-Express features can be carried forward on an upgrade from a System z server. The OSA-Express Token-Ring feature is not supported on z9 servers.

The new OSA-Express2 1000BASE-T Ethernet feature and the OSA-Express2 Gigabit Ethernet (GbE) feature support the new IBM Communication Controller for Linux (CCL) on the System z9 platform and introduces the OSA-Express2 OSN (OSA for NCP) to support the Channel Data Link Control (CDLC) protocol, which provides direct access from the host operating system (such as z/OS and TPF) to the CCL.
