a. Both ports must be defined with the same CHPID type. b. These features are defined by using Function IDs (FIDs). GLYPH<SM590000> FICON channels that are defined as FC or FCP GLYPH<SM590000> OSA-Express features that are defined as OSC, OSD, OSE, OSM, or OSX GLYPH<SM590000> Coupling links that are defined as CS5, CIB, or CL5  GLYPH<SM590000> HiperSockets that are defined as IQD GLYPH<SM590000> Each Crypto Express (5S/6S) feature occupies one I/O slot, but does not have a CHPID  type. However, LPARs in all CSSs have access to the features. Each Crypto Express  adapter can be defined to up to 85 LPARs.  GLYPH<SM590000> Each RoCE Express/Express2 feature occupies one I/O slot but does not have a CHPID  type. However, LPARs in all CSSs have access to the feature. The 10GbE RoCE Express  can be defined to up to 31 LPARs per PCHID. The 25 GbE RoCE Express2 and the  10GbE RoCE Express2 features support up to 126 LPARs per PCHID. GLYPH<SM590000> Each zEDC Express feature occupies one I/O slot but does not have a CHPID type.  However, LPARs in all CSSs have access to the feature. The zEDC feature can be defined  to up to 15 LPARs. GLYPH<SM590000> Each zHyperLink Express feature occupies one I/O slot but does not have a CHPID type.  However, LPARs in all CSSs have access to the feature. The zHyperLink Express adapter  works as native PCIe adapter and can be shared by multiple LPARs. Each port can  support up to 127 Virtual Functions (VFs), with one or more VFs/PFIDs being assigned to  each LPAR. This support gives a maximum of 254 VFs per adapter. Cables:  All fiber optic cables, cable planning, labeling, and installation are client  responsibilities for new z14 installations and upgrades. Fiber optic conversion kits and  mode conditioning patch cables are not orderable as features on z13 servers. All other  cables must be sourced separately. The IBM Facilities Cabling Services fiber transport system offers a total cable solution service  to help with cable ordering requirements. These services can include the requirements for all  of the protocols and media types that are supported (for example, FICON, Coupling Links,  and OSA). The services can help whether the focus is the data center, SAN, LAN, or the  end-to-end enterprise. I/O feature cables and connectors At least one I/O feature (FICON) or one coupling link feature (ICA SR or HCA3-O) must be  present in the minimum configuration.  The following features can be shared and spanned: The following features are exclusively plugged into a PCIe I/O drawer and do not require the  definition of a CHPID and CHPID type: zHyperLink Express 2 2 32 16 Yes N/A b I/O feature Number of Maximum  number of PCHID CHPID  definition Ports  per card Port  increments Ports I/O  slots Chapter 4.
