- an IP address of a cluster node is defined by four bytes whose values are separated by dots, ordering them by the octet with the highest weight. to the lowest weight. Assuming this address is class C, the first three bytes define the server cluster as a local area network, and the last byte allows you to theoretically distribute 255 IP addresses to the nodes of the server cluster. If the server cluster has too many nodes compared to the available addresses in class C, then its IP address can be chosen in class B.

- step 102 of start of generation of the database 72 static data, defining a logical and geographical distribution of the nodes of the cluster in its various networks, and physically defining the nodes of the cluster, are collected and verified by an operator.
- this data is available in the form of digital files, for example tables of data generated using a spreadsheet.
- these documents are generally from a technical study phase following a call for tenders and aimed at defining the precise architecture of the server cluster 14.
- a first table 74 which will be called the logical representation table of the server cluster 14, comprises a list of port-to-port equipment and interconnections constituting the cluster together with all the information enabling them to be uniquely identified as as hardware and as part of the cluster (especially this document assigns credentials for each node in the cluster).
- a second table 76 which will be called the physical representation table of the server cluster 14, provides additional information on the elements of the server cluster, specifying their location in a computer center intended to receive the server cluster. for example by means of a coordinate system, specifying in particular for each cable the necessary length, indicating in addition some constraints of weight or location, etc.
- the verification by the operator consists in ensuring that the fields of the tables 74 and 76 necessary for the generation of the database 72 are well filled.
- a new table file 78 which will be called summary table, is created.
- a first tab is created containing at least the information necessary for the generation of the database 72 from data extracted from the logical representation table 74.
- a second tab is created containing at least the information necessary for the creation of the database. generation of the base 72 from data extracted from the physical representation table 76.
- an additional summary tab lists the hardware component of the server cluster 14. This list can also be extracted from the logical representation table 74.
- each node of the server cluster 14 listed in the summary table 78 is associated, as far as possible, with one of the predetermined profiles based on information already known on this node.
- This profile to which the node is associated is integrated in the synthesis table 78.
- general configuration information of the server cluster 14 is added to the data already recorded in the summary table 78. This information concerns especially :
- the server cluster 14 for its general operation, among which the file management system, the resource management system (the resource management system), the management system of the resources; queues (of the English "batch manager"), the management system for the security of data transmission, and
- step 108 of assigning the IP addresses using the predetermined addressing policy (step 100) and data already entered in the synthesis table 78 on the different elements of the server cluster IP addresses are automatically generated and assigned to the relevant elements.
- a choice of addressing class is made according to the number of bytes necessary for all the elements of the cluster concerned to have an address
- IP addresses of virtual networks are defined according to the general configuration information, and - the available IP addresses are distributed between the nodes of the server cluster 14 according to the predefined formula.
- step 1 10 if in step 104 all the nodes of the server cluster 14 could not be associated with predetermined profiles, or if new servers or storage arrays with unreferenced profiles must be introduced, the missing parameters are completed for example by an operator in the summary table 78.
- step 106 When the summary table 78 is complete, it is saved for possible future use (see step 106) and its data is translated automatically into database manipulation requests 72 of the server cluster 14 which are saved in a request file 80, during a step 1 12.
- step 1 14 an operator checks the result of the translation of data into requests. At this point, an interaction is possible to modify the request file 80.
- this request file 80 is executed by the administration server 18 on site, when the server cluster 14 is installed and in operating state, so as to complete the base of data 72 of the cluster that can then be used to initialize and / or administer the server cluster 14.
