IBM z13s - FICON Express8 S

Chapter 7. Software support 261
7.3.30 FICON Express8S
The FICON Express8S feature is exclusively installed in the Peripheral Component
Interconnect Express (PCIe) I/O drawer. It provides a link rate of 8 Gbps, with auto
negotiation to 4 or 2 Gbps for compatibility with previous devices and investment protection.
Both 10 km (6.2 miles) LX and SX connections are offered (in a feature, all connections must
have the same type).
With FICON Express 8S, clients might be able to consolidate existing FICON, FICON
Express2
2
, and FICON Express4
2
channels, while maintaining and enhancing performance.
FICON Express8S introduced a hardware data router for more efficient zHPF data transfers.
It is the first channel with hardware that is designed to support zHPF, as contrasted to FICON
Express8, FICON Express4
2
, and FICON Express2
2
, which have a firmware-only zHPF
implementation.
Table 7-30 lists the minimum support requirements for FICON Express8S.
