Draft Document for Review September 23, 2019 1:27 am 8860ch15.fm Table 15-1 on page 362 shows the list of applicable functions to the various function types. Refer to the  IBM Z Input/Output Configuration Program User’s Guide,  SB10-7172 for details  about the maximum values for each machine type. Note:  For z15 (M/T 8561) function type zEDC is no longer valid The z15 supports Internal Shared Memory (ISM) virtual PCIe (vPCIe) device to enable  optimized cross-LPAR TCP communications using a socket-based direct memory access  (DMA), the Shared Memory Communications - Direct Memory Access (SMC-D). SMC-D uses a virtual PCIe adapter and is configured like a physical PCIe device. There are  up to 32 ISM adapters, each with a unique Physical Network ID per CPC. ISM is a virtual PCI network adapter that enables direct access to shared virtual memory,  providing highly optimized network communications for operating systems within the same  IBM Z platform. Virtual memory is managed by each z/OS (similar to SMC-R logically shared memory)  following the existing IBM Z PCIe I/O translation architecture.
