Abstract
The invention relates to a novel Rack node medium plate and a design method of the same. The novel Rack node medium plate includes an AST1250 chip, a node module, a fan module and a node mainboard management controller, wherein the node module, the fan module and the node mainboard management controller are connected with the AST1250 chip. The design method of the novel Rack node medium plate includes the following steps: S1, designing a novel Rack node medium plate management system function block diagram; S2, designing a novel Rack node medium plate management system interconnected topology; and S3, designing a novel Rack node medium plate logic block diagram. The novel Rack node medium plate uses the AST1250 to improve the Rack two-level management chip processing capability and efficiency. The node medium plate and the node BMC use a one-to-one I2C channel to realize quick acquisition and reporting of the node information. A WDT (WatchdogTimer) design is added, so that the product reliability is improved. An RTC function is added, the time correctness of system log is guaranteed and the fault reporting accuracy is improved. The node medium plate is communicated with the management mainboard through NIC, so that communication efficiency of Rack one-level management and two-level management.
Description
technical field [0001] The invention relates to a novel Rack node middle board and a design method thereof, belonging to the technical field of Rack server design. Background technique [0002] With the continuous development of the IT industry, the era of cloud computing and big data is coming. With the continuous expansion of Internet applications and the continuous growth of user business needs, high-density server cabinet systems have gradually become a trend. The emergence of Rack server cabinets just meets the development requirements of cloud computing and big data. This Rack server cabinet has a height of 46U. Computing nodes or storage nodes can be freely arranged in each U height space, and a maximum of 3 computing nodes can be deployed in 1U space. [0003] With the improvement of the data processing capability of the Rack server cabinet system, the increase of storage density, and the diversification of node types, higher requirements are put forward for the ma...
