摘要： A method and apparatus for controlling startup of a hard disk drive system, and a storage device. The hard disk drive system includes two or more hard disk drives. The method for controlling startup of a hard disk drive system includes: latching the initialization states of all the hard disk drives after all hard disk drives are powered on; dividing all hard disk drives into two or more hard drive groups, each hard drive group includes more than one hard disk drive; sequentially perform link initialization negotiation on each hard drive group by using a port protocol; and in an OOB negotiation process of the link initialization negotiation, by setting the state of an SCSI application layer power state machine, control a motor of each hard disk drive in the hard drive group to enter a spinning state. The method and apparatus for controlling startup of a hard disk drive system, and the storage device provided in the present disclosure realize staggered startup in batches of a hard disk drive system at low cost, reduce the failure rate of a hard disk backplane, reduce the probability of replacement of a hard disk backplane, and also reduce the operation and maintenance cost.

摘要： A power supply device with dual power source planes and a server. The device includes: a plurality of controllers connected in parallel; a first Power Supply Unit (PSU) power source group and a second PSU power source group each includes two PSU power sources connected in parallel, and the first PSU power source group and the second PSU power source group are respectively located on two independent power source planes; and a power source backboard, wherein the power source backboard includes a first copper skin layer and a second copper skin layer, which are not connected with each other, the first PSU power source group is connected to the input end of each controller by means of the first copper skin layer, and the second PSU power source group is connected to the input end of each controller by means of the second copper skin layer.
