Abstract

A storage device includes a casing; a drive that records data; a controller that controls a data processing of the drive; and a midplane that connects the drive to the controller, in which the midplane includes a plurality of split midplanes which are replaceable, a drive side connector is disposed on a drive side of the split midplane, and the drive side connector is connected to the drive.

First claim

What is claimed is:

1. A storage device comprising:
a casing;
a plurality of drives that record data;
at least one controller that controls data processing of the plurality of drives; and
a midplane that connects the plurality of drives to the at least one controller,
wherein the midplane is disposed substantially perpendicular to a bottom surface of the casing, includes a guide midplane formed of an upper portion and two end portions in a horizontal direction parallel to the bottom surface of the casing, and includes a plurality of split midplanes which are replaceable and are positioned between the two end portions of the guide midplane,
wherein a plurality of drive side connectors are disposed on a drive side of the split midplanes and the two end portions of the guide midplane, wherein the drive side connectors of the split midplanes are between the drive side connectors of the guide midplane, and each of the drive side connectors is connected to one of the drives, respectively, and
wherein a plurality of controller side connectors are disposed on a controller side of the split midplanes and connected to the at least one controller, and each of the controller side connectors is connected to the at least one controller.

2. The storage device according to claim 1 ,
wherein the at least one controller comprises a plurality of controllers,
wherein the midplane is connected to the plurality of controllers via the controller side connectors.

3. The storage device according to claim 1 ,
wherein the at least one controller comprises a plurality of controllers,
wherein a plurality of rows of the controllers are disposed, and
wherein the midplane connects the plurality of rows of the controllers to each other via a connector of the guide midplane.

4. The storage device according to claim 1 ,
wherein the midplane includes the guide midplane with an M shape separately from the split midplanes.

5. The storage device according to claim 1 ,
wherein the midplane includes the guide midplane with a T shape separately from the split midplanes.

6. The storage device according to claim 1 ,
wherein each of the controller side connectors includes a guide pin for an alignment with a corresponding connectors disposed in the at least one controller, respectively.

7. The storage device according to claim 1 ,
wherein each of the controller side connectors is connected to corresponding connectors disposed in the at least one controller, respectively, and
wherein the storage device includes a fixation portion that fixes a tray, which stores a drive of the plurality of drives, to each of the split midplanes, respectively.

8. The storage device according to claim 1 ,
wherein at least one of the drive side connectors has a size that is different from the size of another one of the drive side connectors.

9. The storage device according to claim 1 ,
wherein at least one of the drive side connectors has a transmission performance that is different from the transmission performance of another one of the drive side connectors.

10. The storage device according to claim 8 ,
wherein the at least one of the drive side connectors has a transmission performance that is different from the transmission performance of the another one of the drive side connectors.
