Embodiment Construction

[0012] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings.

[0013] Referring to shown in Fig. 2, it is a preferred embodiment of the SATAII hard disk boot sequence control circuit of the present invention, it is located on the motherboard of computer systems such as general X86 system or embedded system, in order to control and some hard disk connectors 20 The startup sequence of several SATAII hard disks 21 that are electrically connected (plugged in) enables these SATAII hard disks 21 to be started in a staggered manner. One of the characteristics of the SATAII hard disk 21 is to have a staggered startup mode (STAGGERED SPIN UP) that can be started by a driver software control, that is, generally when the SATAII hard disk 21 is powered, it will not start immediately, but will wait until It will start after recei...

Abstract

The pesent invention provides a SATAII hard start sequence control circuit, for controlling the start sequence of SATAII hard inserting in multiple hards connector, and SATAII hard has a start interlaced start mode controlled by a driving software, the circuit is electrically connected one-to-one with these hard connectors by multiple power control units to control SATAII hards inserted in the hard connectors timing output by power, and multiple switch elements are electrically connected one-to-one with these hards connectors, and a hard controller detects whether these hards connectors is inserted with SATAII hards or not, when detecting the multiple hardware connectors inserting in the SATAII hardware, the relative power control units separately supply to these STATII hardwares after inhibiting staggered spin-up mode of these SATAII hardwares by the corresponding switch units. Thereafter, the overload of the power caused by multiple SATAII hardwares start at the same time is avoided.

Description

【Technical field】 [0001] The present invention relates to a hard disk start sequence control circuit, in particular to a SATAII hard disk start sequence control circuit. 【Background technique】 [0002] In order to meet the application requirements of mass data storage, a disk array (DISK ARRAY) composed of multiple hard disks was born accordingly. Therefore, in the disk array, if there is no hard disk boot sequence control, and the power provided by the power supply is insufficient, when all the hard disks are started at the same time, it is easy to cause the power supply to trip due to the instantaneous load. [0003] Therefore, the new generation of SATAII hard disk supports the staggered boot mode (STAGGERED SPIN UP) function. Send power to these SATAII hard disks 10, now SATAII hard disks 10 will not start immediately after being powered, but wait for instructions from the central processing unit 12, therefore, the central processing unit 12 needs to execute a software ...
