I/O Features (Cards) - IBM z13s Technical Manual

Fanout features that are supported by the z13s server are shown in Table 4-5. The table
provides the feature type, feature code, and information about the link that is supported by the
fanout feature.

a. The link data rates do not represent the actual performance of the link. The actual performance is dependent upon
many factors that include latency through the adapters, cable lengths, and the type of workload.
b. When using the 12x IFB3 protocol, synchronous service times are 40% faster than when you use the 12x IFB
protocol.
c. With z Systems qualified DWDM.
d. Auto-negotiated, depending on the DWDM equipment.

4.7 I/O features (cards)

I/O features (cards) have ports
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.
In addition to PCIe I/O features, FICON Express8 features can be installed in I/O drawers.
z13s servers support a maximum of one I/O drawers as carry-forward during an MES. This
drawer represents a maximum of 8 FICON Express8 features (a total of 32 FICON Express8
ports) that can be carried forward.
Consideration: The installation of an I/O drawer limits the LPAR storage to 1 TB
(independent from the IOCP definition). Moreover,
configuration as follows:
The total fanout slots for PSIFB are reduced by two.
