Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. The embodiment of the present invention modifies the carrier board manager of the carrier board switch (MicroTCA Carrier Hub, MCH) of the existing MTCA platform and the base management controller (Base Management Controller, BMC) on the system board, and adds a thermal The pluggable driver enables the MTCA platform to support full hot plugging.

[0033] In the standard MTCA system structure, the system board (CPU Board) is regarded as a common AMC card, for the convenience of description, the embodiment of the present invention provides the simplified structure of the MTCA platform, as figure 1 As s...

Abstract

The invention is applied to the field of computers, which provides a hot swapping method based on multiple terminal communication adapter (MTCA) platform and a multiple terminal communication adapter (MTCA) platform. The method comprises the following steps: allocating hot swapping control orders; allocating a hot swapping drive on a master operating system of a system board, wherein the hot swapping drive is based on intelligent platform management interface (IPMI) standard and used for analyzing received hot swapping control orders; generating hot swapping event-driven signals and executing hot swapping operation of a module; and achieving full hot swapping of the module between a machine check handler (MCH) of a loading board swapper and the hot swapping drive through hot swapping action parameters carried by the hot swapping control orders and data of a bus link of a back board of the module. The loading board swapper of the MCH and a block multiplexer channel (BMC) are modified based on a standard power-on flow and a standard power-off flow specified by automatic message counting (AMC) standard and the MTCA standard, and the hot swapping drive is added, thereby enabling the MTCA platform to support the full hot swapping and the MCH and the system board to be compatible with other platforms which do not support the full hot swapping.

Description

technical field [0001] The invention belongs to the field of computers, in particular to an MTCA platform-based hot plugging method and the MTCA platform. Background technique [0002] In the specification PICMG2.1R2.0-Hot Swap Specification (Hot Swap Specification) of PCI Industrial Computer Manufacturers Group (PCI Industrial Computer Manufacturers Group, PICMG), the description of hot-swap processing is divided into physical connection (Physical connection), hardware Connection (Hardware connection) and software connection (Software connection) three connection stages. [0003] In a system, hot-swappable components include a board (Board), a system board (System Host) and a platform (Platform). Boards other than the system board can be classified into three hot-swappable types: non-hot-swappable, basic hot-swappable, and full hot-swappable. Basic hot-swappable boards have only the minimum features required for hot-swap. [0004] Platforms are also divided into three ty...
