In a data processing environment, a communication interface of a second host data processing system receives host commands in a first set of commands from a first host data processing system. The host command specifies a memory access to a memory coupled to the second host data processing system. The communication interface translates the host command to a command in a different second set of commands that emulates coupling of the attached functional unit to the communication interface. The communication interface presents the second command to a host bus protocol interface of the second host data processing system. Based on receipt of the second command, the host bus protocol interface initiates a host bus protocol memory access request specifying a memory access on a system fabric of the second host data processing system. 在数据处理环境中，第二主机数据处理系统的通信接口接收来自第一主机数据处理系统的第一命令集中的主机命令。主机命令指定对耦合到第二主机数据处理系统的存储器的存储器访问。通信接口将主机命令转换为模拟附接的功能单元到通信接口的耦合的不同的第二命令集中的命令。通信接口将第二命令呈现给第二主机数据处理系统的主机总线协议接口。基于第二命令的接收，主机总线协议接口在第二主机数据处理系统的
