Abstract: The configuration and maintenance of a computer system in a cluster, where the computer system is configured to allow booting from data stored in an administration computer system is disclosed. In one aspect, after obtaining a boot disk image making it possible to boot an operating system and configuration data from the administration computer system, the operating system is booted and configured and a virtual storage disk is created. The configuration data received are analyzed in order to obtain and store in the virtual disk a program for the configuration of the computer system. The program for the configuration of the computer system is then executed.

Abstract: A method of operating a computer system in communications, via a communication network, with a server comprising an image of a kernel of a minimal operating system and an image of an associated file system for the computer system includes loading, via the communication network, the kernel image from the server to the computer system in accordance with a network transfer protocol interface, and loading, via the communication network, the file system image from the server to the computer system in accordance with the same network transfer protocol interface used to load the kernel image, wherein the loading of the kernel image from the server to the computer system is launched before the loading of the file system image from the server to the computer system is completed, and wherein the loading of the file system image from the server to the computer system is launched before the loading of the kernel image from the server to the computer system is completed.

Abstract: A blade of components for a computer system, intended to be inserted into a computer system rack, is disclosed. In one aspect, it includes a frame with means for electrically connecting to the computer rack, and a computer component holder having a plurality of through-slots configured to receive computer components translatably along the longitudinal direction of the slot. The component holder is movably mounted by means of a slide connection in relation to the frame, such that it can move between a first position in which the holder is inserted substantially into the frame and a second position in which the holder is at least partially removed from the frame, such that the vertical line of all of the slots is kept free along the longitudinal direction of each in order to allow the translatable insertion and extraction of computer components along the longitudinal direction.

Abstract: The dynamic monitoring of distances, in particular of memory access distances, in a non-uniform memory access (NUMA) type system comprising a plurality of processors, and a local memory being associated with each processor of the plurality of processors is disclosed. In one aspect, after having obtained at least one NUMA distance between at least one first processor of the plurality of processors and a local memory associated with at least one second processor of the plurality of processors, the at least one NUMA distance obtained is stored in place of at least one NUMA distance, previously stored, between the at least one first processor and the local memory associated with the at least one second processor, the at least one NUMA distance stored being usable directly by the operating system of the NUMA type system.

Abstract: A method of starting up a computing device a network comprising a dynamic addressing module and a module for providing start-up files for the computing device comprising allocating to the computing device, by the dynamic addressing module, an address in the network; transmitting, by the computing device to the module for providing start-up files, at least one request (ReqB) for start-up files; and providing by the module for providing start-up files to the computing device, the start-up files in response to said at least one request. The at least one request includes the address of the computing device, allocated by the dynamic addressing module, and the start-up files are provided by the file server with this address.

Abstract: The subject of the invention is in particular the optimization of the loading and booting of an operating system of a computer system via a communication network to which at least one server is connected. Said server comprises at least one image of a kernel of a minimal operating system and an image of an associated file system. The method comprises steps of loading said image of said kernel (330) and said image of said file system (325). One of said steps of loading said image of said kernel (330) and of loading said image of said file system (325) is launched before the end of the implementation (335, 340) of the other of said steps of loading said image of said kernel and of loading said image of said file system.

Abstract: The invention relates to a blade (10) of components (40) for a computer system, intended to be inserted into a computer system rack and comprising: a frame (20) with means (21) for electrically connecting to the computer rack, and a computer component holder (30) having a plurality of through-slots (31) configured to receive computer components (40) translatably along the longitudinal direction of the slot. The component holder (30) is movably mounted by means of a slide connection in relation to the frame (20), such that it can move between a first position in which the holder is inserted substantially into the frame and a second position in which the holder is at least partially removed from the frame, such that the vertical line of all of the slots (31) is kept free along the longitudinal direction of each in order to allow the translatable insertion and extraction of computer components (40) along said longitudinal direction.
