270 IBM z13s Technical Guide

Table 7-40 lists the minimum support requirements for OSA-Express5S 1000BASE-T.

Table 7-40 Minimum support requirements for OSA-Express5S 1000BASE-T Ethernet

7.3.44 OSA-Express4S 10-Gigabit Ethernet LR and SR

The OSA-Express4S 10-Gigabit Ethernet feature, introduced with the zEC12, is installed

exclusively in the PCIe I/O drawer. Each feature has one port, which is defined as either

CHPID type OSD or OSX. CHPID type OSD supports the QDIO architecture for high-speed

TCP/IP communication. The z196 introduced the CHPID type OSX. For more information,

see 7.3.50, “Intraensemble data network” on page 274.

The OSA-Express4S features have half the number of ports per feature when compared to

OSA-Express3, and half the size as well. This configuration results in an increased number of

installable features. It also facilitates the purchase of the correct number of ports to help

satisfy your application requirements and to better avoid redundancy.
