Abstract: A computer system includes a shared I/O device including functions providing access to device local memory space, and a plurality of roots coupled to the shared I/O device via a switch fabric. A first root assigns a first address in a first root memory space to a first function. A second root assigns a second address in a second root memory space to a second function. The switch fabric maps the first root memory space to a first portion of device local memory space and the second root memory space to a second portion of device local memory space. Subsequently, the switch receives a data transaction request from the first root targeted to the first address, translates the first address to a corresponding location in the first portion of the device local memory space based on the mapping, and routes the data transaction request to the I/O device.

Abstract: A method of assigning IP addresses to a plurality of managed servers coupled is provided. A set of address correlations is stored, at least temporarily, at a management server coupled to the managed servers. Each address correlation comprises a correlation between one of a plurality of geographic identifiers and one of a plurality of IP addresses. Each geographic identifier identifies a possible physical location of a managed server. A geographic identifier at least partially identifying the physical location of the managed server is received at the management server from a particular managed server. The IP address corresponding to the received geographic identifier is determined from the set of address correlations and assigned to the particular managed server.
