Fanout features that are supported by the z14 server are listed in Table 4-3, which includes  the feature type, feature code, and information about the link supported by the fanout feature. I/O features (cards) have ports$^{3}$ to connect the z14 server to external devices, networks, or  other servers. I/O features are plugged into the PCIe I/O drawer, based on the configuration  rules for the server. Different types of I/O cards are available, one for each channel or link  type. I/O cards can be installed or replaced concurrently. The I/O features that are supported by z14 servers and the ordering information for them are  listed in Table 4-4. 4.6.1 I/O feature card ordering information 4.6 I/O features (cards) a. The link data rates do not represent the actual performance of the link. The actual performance depends on many  factors, including latency through the adapters, cable lengths, and the type of workload. b. When the 12x IFB3 protocol is used, synchronous service times are 40% faster than the 12x IFB protocol. c. Up to 100 km (62 miles) with repeaters (IBM Z qualified DWDM).
