Channel options
Table B-1 on page 140 lists the attributes of the channel options that are supported on zEC12 systems, the required cable type, the maximum unrepeated distance, and the bit rate.
For all optical links, the connector type is LC Duplex, except the 12xIFB connection is established with an MPO connector. The electrical Ethernet cable for the Open Systems Adapter (OSA) connectivity is connected through an RJ45 jack.
|
Statement of direction:
•The zEC12 is planned to be the last IBM System z® server to support ISC-3 Links. Enterprises should continue migrating from ISC-3 features to InfiniBand Coupling Links.
•The zEC12 is planned to be the last IBM System z® server to support Ethernet half-duplex operation and 10-Mbps link data rate on 1000BASE-T Ethernet features. Any future 1000BASE-T Ethernet feature will support full-duplex operation and auto-negotiation to 100 or 1000 Mbps exclusively.
•The zEC12 is planned to be the last IBM System z® server to support OSA-Express3 Family of features. Enterprises should continue migrating from the OSA-Express3 features to the OSA-Express4S features.
•The zEC12 is planned to be the last IBM System z® server to support FICON Express4 features. Enterprises should continue migrating from the FICON Express4 features to the FICON Express8S features.
•The zEC12 is planned to be the last IBM System z® server to support Crypto Express3 feature. Enterprises should begin migrating from the Crypto Express3 feature to the Crypto Express4S feature.

1 Minimum fiber bandwidth distance product in MHz·km for multimode fiber optic links are included in parentheses, where applicable.
2 RPQ 8P2197 enables the ordering of a daughter card supporting 20 km unrepeated distance for 1 Gbps peer mode. Request for price quotation (RPQ) 8P2262 is a requirement for that option, and other than the normal mode, the channel increment is two (that is, both ports (FC 0219) at the card must be activated).
