Abstract: A method in a system that includes first and second devices that communicate with one another over a fabric that operates in accordance with a fabric address space, and in which the second device accesses a local memory via a local connection and not over the fabric, includes sending from the first device to a translation agent (TA) a translation request that specifies an untranslated address in an address space according to which the first device operates, for directly accessing the local memory of the second device. A translation response that specifies a respective translated address in the fabric address space, which the first device is to use instead of the untranslated address is received by the first device. The local memory of the second device is directly accessed by the first device over the fabric by converting the untranslated address to the translated address.

Abstract translation: 一种系统中的方法，包括通过结构上的彼此通信的第一和第二设备，所述结构根据结构地址空间操作，并且其中所述第二设备经由本地连接而不是所述结构访问本地存储器，包括 从第一设备向翻译代理（TA）发送指定第一设备所运行的地址空间中的非翻译地址的翻译请求，用于直接访问第二设备的本地存储器。 指定第一设备将使用而不是非翻译地址的结构地址空间中的相应翻译地址的翻译响应由第一设备接收。 第二设备的本地存储器通过将非翻译地址转换为转换的地址，由第一设备直接通过结构访问。
