the options to be considered is locating one of the Sysplex Timers in an intermediary site that is less than 40 km from one of the two sites (as can be seen in the diagram below). Other potential options can be evaluated when the RPQ is ordered.

•ISC-3. InterSystem Channel-3 provides the connectivity required for resource or data sharing between the Cou- pling Facility and the systems directly attached to it.

ISC-3s are point-to-point connections that require a unique channel defi nition at each end of the channel. ISC-3 channels operating in Peer Mode provide con- nection between zSeries (z800/z900/z990) general purpose models and zSeries Coupling Facilities. ISC-3 channels operating in Compatibility Mode provide con- nection between zSeries and HiPerLink (ISC-2) channels on 9672 G5 and G6 and the 9674 R06 Models. A four port ISC-3 card structure is provided on the z990 pro- cessors. It consists of a mother card with two daughter cards which have 2 ports each. Each daughter card is capable of operation at 1 Gbps in Compatibility Mode or 2 Gbps in Peer Mode up to a distance of 10 km. From 10 to 20 km, an RPQ card which comes in 2 port incre- ments is available which runs at 1 Gbps in both Peer and Compatibility Modes. The mode is selected for each port via CHPID type in the IOCDS. The ports are acti- vated in one port increments.

•ISC-2. HiPerLinks. HiPerLinks, based on single-mode CF links, are available on 9672s (G3 - G6) and 9674s only. ISC-3s replace HiPerLinks on zSeries 900 and z990 models.

•ICB-2. The Integrated Cluster Bus-2 is used to provide high-speed coupling communication between a zSeries server or CF and a 9672 G5/G6 server or CF over short distances (~7 meters). For longer distances, ISC links must be used. The z990 features the STI-2 card which resides in an I/O cage and provides 2 ICB-2 ports each capable of up to 333 MBps. The ports are activated in one port increments. Up to 4 STI-2 cards, 8 ICB-2 links are available on the z990.
