US 5,414,591 A · Magnetic disk storage system

Abstract

A magnetic disk storage system in which magnetic disk drives can be cooled effectively, and even if a blast device for one of he magnetic disk drives fall into trouble or cease operation, a temperature rise of this magnetic disk drive can be suppressed to the minimum. For this purpose, in the magnetic disk storage system containing a plurality of magnetic disk drives, blase devices ae provided for each of the disk drives, and the disk drives are separated by partitions in which openings are formed so that the cooling air can be passed between adjacent magnetic disk drives. With this structure, even if a blast device for a certain magnetic disk drive is out of order or stopped, a part of the cooling air from a blase device for the adjacent disk drives flows into the magnetic disk drive in question through the openings formed in the partitions, and consequently, the temperature rise of the magnetic disk drive whose blase device ceases operation can be suppressed to the minimum, to thereby enhance the reliability of the magnetic disk storage system.

Dependent claims

A magnetic disk storage system comprising a plurality of magnetic disk drives provided in a system casing, each of the magnetic disk drives including magnetic disks for storing information, magnetic heads for reading and writing information between said magnetic disks, a carriage mechanism for positioning said magnetic heads, and a housing for hermetically sealing them,

said magnetic disk storage system further comprising partitions for separating and arranging said magnetic disk drives for which partitions are provided between said disk drives so as to form container chambers of the disk drives, and blast means for cooling said magnetic disk drives which blast means are provided in said container chambers, said partitions being formed with openings through which cooling air is passed between adjacent two of said container chambers, each of said openings being positioned in said partitions so that one of said disk drives is cooled by the cooling air which is passed through said openings in one of said partitions from said blast means for an adjacent container chamber to said one of said disk drives when the blast means for said one of said disk drives cannot supply cooling air to said one of said disk drives.

said magnetic disk storage system further comprising partitions for separating and arranging said magnetic disk drives which partitions are provided between said disk drives, said partitions being formed with openings through which the cooling air can be passed between adjacent two of said magnetic disk drives in addition-to inlets and outlets of the cooling air, said partitions forming frames on which the magnetic disk drives-are mounted, which partitions, said magnetic disk drives and blast means for cooling said disk drives constitute magnetic disk drive units, said partitions being provided in said system casing so as to support said magnetic disk drive units individually, said partitions being formed with openings other than inlets and outlets for cooling air for said magnetic disk drive units through which the cooling air can be passed between adjacent two of said magnetic disk drive units, each of said openings being positioned in said partitions so that said disk drive of one of said magnetic disk units is cooled by the cooling air which is passed through said openings in said partitions from said blast means for an adjacent magnetic disk unit when the blast means for said one magnetic disk unit cannot supply cooling air to said one magnetic disk unit.
