Embodiment Construction

[0052] The invention realizes an efficient single-image control system by setting an out-of-band management link in the switch system, which is named as SIC. SIC integrates the status information of multiple switching boards in high-density switches to form a single super node, which can simplify the network topology and make the network easy to manage and maintain. On the other hand, because the SIC adopts the out-of-band management method, the status update delay in the in-band management and the dependence on the managed objects are eliminated, and uninterrupted management is supported.

[0053] The single image control system consists of two parts: a single image main controller (SIMC, Single Image Main Controller) and a single image switching board controller (SIBC, Single Image Baseboard Controller). The single-image main controller mainly monitors the status of the switch board, and assigns the GUID and port number of the switch board. The single-image switch board con...

Abstract

The invention relates to a single image control method and system for a high density Infiniband switch. The method comprises: 1. a switch management system informs a single image main controller of the GUID (globally unique identifier) of an available switch module; 2. the single image main controller scans an on-line switch board in the switch to assign the GUID to the switch board and unanimously number the externally connected ports of the switch board; 3. the single image main controller updates the arrangement firmware of the switch module by utilizing the assigned GUID of the switch module and the numbers of the ports and resets the switch module; and 4, after confirmation of completion of updating, the single image main controller informs the management system of the switch of the single image status of the switch. According to the invention, a single image is formed by rendering the high density switch as a large-scale single node with a unique identifier in the network and hiding the internal chains and status of the high density switch so as to facilitate the management and network topology maintenance.

Description

technical field [0001] The invention relates to an Infiniband switch, in particular to a method for implementing single image control on a high-density Infiniband switch. Background technique [0002] Infiniband switching technology has been increasingly widely used in the field of high-performance computing due to its high performance, high reliability and high scalability. 30% of the systems in TOP500 released in June 2010 adopt Infiniband interconnection technology. A large number of nodes in a supercomputer need to be interconnected through Infiniband switches, and high-density Infiniband switches are usually used to build a data network in system design. [0003] A high-density Infiniband switch is usually composed of multiple basic switching modules, and the switching modules have the same functions. Each basic switching module implements small-scale switching, and multiple switching modules in the switch implement high-density interfaces through interconnection. Ba...
