OSA-Express Fast Ethernet (FENET), OSA-Express 155 ATM and OSA-Express Gigabit Ethernet (GbE) are the newest features in the lineup of Local Area Network (LAN) adapters offered under the covers of S/390 Parallel Enterprise Server Generation 5 and Generation 6.

OSA-Express has one physical network adapter or OSA port. Its physical port can be attached directly to a LAN. This integration of channel path with network port makes OSA-Express a unique type of S/390 channel, recognized by the hardware I/O configuration as one of the following:

·         OSD (QDIO)

·         OSE (non QDIO)

Reports for the following are shown:

·         Processor utilization

·         Physical PCI bus utilization

·         Ethernet port diagnostics

There are three OSA-Express type variables:

·         OSAExpress (G)

·         OSAPerformance (G)

·         OSAEthernet (G)

The (G) after each variable indicates that graphs are available.
