Problems solved by technology

Then a main system manages all cascaded devices. In this case, when a hard disk fails, the main system cannot clearly display the specific problems at each level, and designers and users cannot easily find the point of failure.
This increases the time for storage system development, and also increases the labor intensity of the staff

Embodiment Construction

[0017] Refer to the following figures to describe in detail the indication principles of the ID numbers at all levels of the cascaded system.

[0018] Add a dial switch with digital display on the front control panel of each level, such as: digital display 0...9, and indicate the ID number of each level by turning the toggle switch to the corresponding number. When the DIP switch is set to a certain number, the Pin of the DIP switch is set to the GPIO Pin of the main control chip or the expansion chip, and the system assigns an ID number to the series of each chip through these four GPIO Pins. One-to-one correspondence with the ID number displayed by the DIP switch.

[0019] Specifically related to the design of the line, it is divided into the following aspects:

[0020] 1) Select the DIP switch with 8421 principle to indicate the ID number of each level;

[0021] 2) The system detects the 8421 DIP switch through the GPIO Pin of the main chip, sets the high and low bits of ...

Abstract

The invention provides a design technique allowing ID numbers of all stages in a cascade system to be indicated and belongs to the field of memory systems. A dial switch with function of digital display is added to each stage of a front control panel; the ID numbers of the stages are indicated by toggling the dial switches to corresponding numbers. When the dial switches are toggled to the certain number, pins of the dial switches set GPIO pins of a master control chip or extension chip; the system provides ID numbers for the stages of the chips through the GPIO pins; the ID numbers are in one to one correspondence with the ID numbers that the dial switches display; accordingly, each stage of system can be managed conveniently.

Description

technical field [0001] The invention relates to the field of storage systems, in particular to a design technology capable of indicating ID numbers at all levels of a cascade system. Background technique [0002] Storage system (memory system) refers to a computer system composed of various storage devices for storing programs and data, control components, devices (hardware) and algorithms (software) for managing information scheduling. The main memory of the computer cannot meet the requirements of fast access speed, large storage capacity and low cost at the same time. In the computer, there must be a multi-level memory with a speed from slow to fast and a capacity from large to small. With the optimal control scheduling algorithm and Reasonable cost constitutes a storage system with acceptable performance. [0003] When developing and designing the storage system, it is necessary to take into account the user's requirement for a hard disk array with multi-level cascadin...
