Disk device

A disk device comprising:

• a chassis;
• columns of drives each having disk drives which are arranged in a depth direction in the chassis;
• and
• wiring boards for the columns of disk drives;
• wherein the columns of drives are spaced each other in height and width directions in the chassis with predetermined distances,
• wherein each wiring board is disposed between two columns of drives neighboring each other in the width direction so that a disk surface of rotation of each disk drive is perpendicular to a board surface of a wiring board, and both surfaces of the wiring board have each a connection surface for disk drive, and
• wherein the disk device further comprises drawer units each providing simultaneous extraction of the wiring board and at least the two columns of drives from the chassis.

A disk device comprising:

• a chassis;
• columns of drives each having disk drives which are arranged in a depth direction in the chassis;
• wiring boards for the columns of disk drives;
• and
• blowers for cooling the disk drives;
• wherein the columns of drives are spaced each other in height and width directions in the chassis with predetermined distances,
• wherein each wiring board is disposed between two columns of drives neighboring each other in the width direction so that a disk surface of rotation of each disk drive is perpendicular to a board surface of a wiring board, and both surfaces of the wiring board have each a connection surface for disk drive, and
• wherein the disk device further comprises drawer units each providing simultaneous extraction of the wiring board, at least the two columns of drives and the blowers from the chassis.

A disk device comprising:

• a chassis;
• columns of drives each having disk drives which are arranged in a depth direction in the chassis;
• wiring boards for the columns of disk drives;
• and
• blowers for cooling the disk drives;
• wherein the columns of drives are spaced each other in height and width directions in the chassis with predetermined distances and attached to the wiring boards so that a disk surface of rotation of each disk drive is perpendicular to a board surface of a wiring board,
• wherein two wiring boards are arranged with a predetermined distance spaced in a width direction, the two wiring boards having connection surfaces for disk drive which face opposite directions,
• wherein the disk device comprises drawer units each providing simultaneous extraction of at least two columns of drives attached to the two wiring boards and the blowers from the chassis,
• wherein the predetermined distance for the two wiring boards is greater than a summation of a width of a column of drives and a thickness of the wiring board, and
• wherein a pair of drawer units is adapted to be drawn out mutually oppositely in the depth direction in the chassis.

A disk device comprising:

• disk drives;
• wiring boards which activate the disk drives;
• blowers for cooling the disk drives;
• plural drawer units each providing simultaneous extraction of the disk drives, the wiring boards and the blowers;
• and
• a chassis in which the drawer units are stored,
• wherein the disk drives are arranged on both board surfaces of a wiring board in plural rows with a predetermined distance spaced in a depth direction and in plural tiers with a predetermined distance spaced in a height direction in the chassis,
• wherein the wiring board is arranged so that a board surface of the wiring board is perpendicular to a disk surface of rotation of each disk drive,
• wherein a logical group for data redundant configuration is established by a combination of the disk drives in the drawer units, and
• wherein the drawer units are adapted to be drawn out in the depth direction from the chassis.
