d. On z14 ZR1, the CHPID statement of HiperSockets devices requires the keyword VCHID.  Therefore, the IOCP definitions must be migrated to support the HiperSockets definitions  (CHPID type IQD). VCHID specifies the virtual channel identification number that is associated  with the channel path (valid range is 7E0 - 7FF). VCHID is not valid on Z servers before z13. e. Applicable to guest operating systems. f. Shared Memory Communications - Direct Memory Access. g. Remote Direct Memory Access (RDMA) over Converged Ethernet. h. Linux can use RocE Express as a standard NIC (Network Interface Card) for Ethernet. i. Does not require a peer OSA. j. Supported CHPID types: OSC, OSD, OSE, and OSM. k. OSC, OSX, and OSE channel types not supported on a CPC running in DPM mode. 7.3.4 Cryptographic functions The supported cryptography functions for z/OS and z/VM are listed in Table 7-10.
