A device for mixing hard disk control signals by a controller

Abstract

The invention discloses a device for mixing hard disk control signals via a controller. The device comprises the controller and a hard disk backboard; at least a group of connection trough positions for connecting the controller; each group of connection troughs comprises a hard disk trough position for connecting a hard disk connector and an ID identification trough position for identifying the group of connection trough positions; connection pins adapted to the connection slot trough positions on the hard disk backboard are arranged on the controller; the connection pins comprise hard disk pins adapted to the hard disk trough positions and ID identification pins adapted to the ID identification trough positions; a management chip which is connected with the connection pins is arranged inthe controller; and at least one set of indicator codes which are same as the connection trough positions in the aspect of quantity and which are used for setting a hard disk corresponding to each control signal are burnt in the management chip. The device is capable of simplifying the Layout routing, decreasing the board layers and saving the cost.

Description

technical field [0001] The invention relates to a hard disk control device, in particular to a device for mixing hard disk control signals by a controller. Background technique [0002] Storage server products take data storage as the primary function, so general storage products are designed to support multiple hard disks, and what’s more, they can support more than 20 hard disks. For mid-to-high-end storage servers, in order to ensure the reliability of production, a single complete machine needs to be designed to support dual controllers to access the same hard disk, and the two controllers use the same design. [0003] When two controllers are connected to the same hard disk backplane, in order to optimize the structure and avoid the interference between the docking connector of the controller main board and the backplane and the hard disk connector on the backplane, the two controllers need to be designed with one up and one down, one positive and one reverse , and the...

Problems solved by technology

At this time, if figure 2 As shown, in order to ensure that different signals are not connected together to avoid short circuits caused by signal connections, Layout must pass through the PCB board from different layers, which will inevitably lead to complicated layout routing and more PCB board layers
