Multibus is a computer bus standard used in industrial systems. It was developed by Intel Corporation and was adopted as the IEEE 796 bus. The Multibus specification was important because it was a robust, well-thought out industry standard with a relatively large form factor, so complex devices could be designed on it. Because it was a well-defined and well-documented industry standard, it allowed a Multibus-compatible industry to grow around it, with many companies making card cages and enclosures for it. Many others made CPU, memory, and other peripheral boards. In 1982 there were over 100 Multibus board and systems manufacturers. This allowed complex systems to be built from commercial off-the-shelf hardware, and also allowed companies to innovate by designing a proprietary Multibus board and then integrating it with other vendors' hardware to create a system. A good example of this was Sun Microsystems with their Sun-1 and Sun-2 workstations. Sun built custom-designed CPU, memory, SCSI, and video display boards, and then added 3Com Ethernet networking boards, Xylogics SMD disk controllers, Ciprico Tapemaster 1/2 inch tape controllers, Sky Floating Point Processor, and Systech 16-port Terminal Interfaces in order to configure the system as a workstation or a file server. Other workstation vendors who used Multibus-based designs included HP/Apollo and Silicon Graphics.
Equipment management system and server
The invention discloses an equipment management system and a server, and relates to the technical field of servers, and the equipment management system is characterized in that a topology identifier storage assembly for storing slot position signal source identifiers is moved to a server mainboard end, so that the occupation of mainboard connector pins by information transmission is reduced; and meanwhile, the management control component establishes and stores a corresponding relation between the address of the arbitration component and the screen printing area of the case. The adapter card does not need to be pre-bound and configured, can automatically identify the screen printing area of the case through the relationship by inserting any communication interface of the mainboard, and generates slot screen printing information in combination with the pre-stored signal source identifier. The problems that a large number of pins are occupied due to the fact that the adapter card hardware address signal identification configuration needs to be transmitted through a connector, and the adapter card needs to be bound with the fixed configuration and lacks flexibility in the prior art are solved. The technical effects of reducing pin occupation, realizing flexible plugging of the adapter card and automatic identification of screen printing, reducing hardware development cost and meeting the requirement of the server for reserving more bus interfaces for the connector are achieved.

Equipment bus digital twin parallel training evaluation and control method and system
This invention discloses a method and system for parallel training, evaluation, and control based on a digital twin using an equipment bus. It unifies the time-stamping and state-space mapping of multi-bus observation data, and solves for a unified state estimate based on quality indicators, fusion residuals, and cross-bus physical consistency constraints. This drives the state evolution of the digital twin, executing the Lyapunov descent admission condition under synchronization error and end-to-end delay constraints. Further, multi-scenario parallel simulations are conducted to obtain an upper bound on the risk probability and construct a training evaluation function. When the evaluation is below a threshold or the risk exceeds the limit, only the affected control components are subject to safe feasible region projection correction, and closed-loop control commands are output. This invention improves state estimation accuracy, synchronization stability, risk prediction capability, and training control safety.
