Problems solved by technology
[0004] However, when more than two IDE hard disks are used in NAS, the circuit and method of the IDE hard disk array system cannot recognize the ID of the IDE hard disk.
[0005] And if more IDE hard disk devices are used in the NAS, for example, if 8 IDE hard disk devices are connected, when they are started at the same time, the instantaneous peak current will be as high as 16A, and the ordinary power supply cannot withstand such a large power consumption, which is extremely difficult. It is easy to burn out, so it is necessary to provide a startup circuit and method for delaying startup of multiple IDE devices to reduce its power consumption during startup and ensure the normal operation of the entire system

An ID circuit of an designated IDE device includes a host, multiple IDE devices, multiple indicating lamps and multiple controllers, among which, the host includes multiple ID indicating foot positions for designating ID values and an ID design foot position, each said lamp corresponds to one IDE device, the said multiple controllers are connected with the ID indicating foot positions of the host and different IDE device, different indication lamps. The method includes the following steps: firstly, the host designs ID indicating foot position value connected with each controller, then to designate the ID of the said IDE according to the said ID indicating foot position indirectly.
Description
【Technical field】 [0001] The present invention relates to a circuit and method for specifying an IDE device ID, in particular to a circuit and a method for specifying an IDE device ID for network attached storage (Network Attached Storage, NAS). 【Background technique】 [0002] With the development of computer technology and the advancement of science and technology, people urgently need to obtain effective resources from various places. The development of the Internet era, coupled with the application of multimedia, makes the data running on different system platforms grow rapidly in a geometric progression. The traditional server-centric storage network architecture has become incapable of facing the continuous data flow. People hope to find a new data storage mode that is independent of storage devices and has good scalability, availability and reliability to meet future data storage requirements. Therefore, according to this demand, a new data storage mode of NAS was de...
