Method for assigning logical addresses to connection ports of devices of a server cluster, comprising the following steps: - defining a logical addressing policy of said device connection ports of the cluster, - based on a logical distribution of the devices in the server cluster, a geographic distribution and a hardware definition (74, 76) of the devices of the cluster, initializing a server cluster administration database by: • translating data related to this logical distribution, this geographic distribution and this hardware definition (74, 76) into requests for handling the database, • saving (110, 112) these requests, and • executing these requests for completing the database, - according further to the logical addressing policy, assigning logical addresses to said device connection ports of the server cluster, and - saving the assigned logical addresses in the server cluster administration database, comprising executing (204, 206) an automatic logical address allocator based on execution parameters that include a structured description file of the logical addressing policy, wherein: - initializing the administration database, including executing these requests, is performed without assigning logical addresses to said device connection ports of the server cluster, - the structured description file includes a tree structure of logical networks and of logical address ranges in these logical networks, and - the execution parameters for the automatic logical address allocator further include the content, obtained by executing said requests, of the previously initialized administration database so as to apply thereto the tree structure of the structured description file to assign the logical addresses to said device connection ports of the server cluster, and - the automatic logical address allocator is executed after executing the initialization of the database. - defining a logical addressing policy of said device connection ports of the cluster, - based on a logical distribution of the devices in the server cluster, a geographic distribution and a hardware definition (74, 76) of the devices of the cluster, initializing a server cluster administration database by: • translating data related to this logical distribution, this geographic distribution and this hardware definition (74, 76) into requests for handling the database, • saving (110, 112) these requests, and • executing these requests for completing the database, • translating data related to this logical distribution, this geographic distribution and this hardware definition (74, 76) into requests for handling the database, • saving (110, 112) these requests, and • executing these requests for completing the database, - according further to the logical addressing policy, assigning logical addresses to said device connection ports of the server cluster, and - saving the assigned logical addresses in the server cluster administration database, - initializing the administration database, including executing these requests, is performed without assigning logical addresses to said device connection ports of the server cluster, - the structured description file includes a tree structure of logical networks and of logical address ranges in these logical networks, and - the execution parameters for the automatic logical address allocator further include the content, obtained by executing said requests, of the previously initialized administration database so as to apply thereto the tree structure of the structured description file to assign the logical addresses to said device connection ports of the server cluster, and - the automatic logical address allocator is executed after executing the initialization of the database.
