Abstract

Noise is reduced in a disk drive enclosure by using vibration damping materials on the inside surface of the enclosure. These materials and their placement on the inside surface of the enclosure reduce noise without thermally insulating the disk drive. A temperature controlled fan may be used to remove heat by convection while generating a minimum amount of noise. The connection between the disk drive and the external connector of the disk drive enclosure is made more reliable by using a printed circuit board instead of a cable. Because a printed circuit board has a fixed location and fixed layout, variability among disk drive enclosures can be minimized. Also, errors in manufacturing of the disk drive enclosure can be reduced. To facilitate the use of the disk drive in a stripe set, the disk drive enclosure has a set of mechanical interlocks that permit the enclosures to be stacked vertically. In one embodiment, the mechanical interlocks are constructed in a manner that permits stacking in unlocked and locked configurations. The locked configuration may be made permanent using an additional locking mechanism. These mechanical interlocks also may be used to support the enclosure on a desktop. The mechanical interlocks also may be constructed so that they can slide on a rail, permitting the enclosure to be used in a rack mount. The rack mount also may be provided with a quick-release mechanism that interacts with the mechanical interlocks to hold the disk drive enclosure in the rack mount.

Claims

1. A disk drive enclosure, comprising:

a housing for enclosing a disk drive;

a first plurality of mechanical interlocks mounted on a first side of the housing;

a second plurality of mechanical interlocks mounted on a second side of the housing opposite the first side of the housing;

wherein each of the first and second plurality of mechanical interlocks has a top portion having a surface complementary to a surface of a bottom portion of the mechanical interlock, such that the top portion of a first mechanical interlock and the bottom portion of a second mechanical interlock are slidably connectable in a first direction and when connected prohibit movement of the mechanical interlocks with respect to each other in second and third directions orthogonal to the first direction.

2. The disk drive enclosure of claim 1, wherein the top portion has top face and the bottom portion has a bottom face such that the top face of the top portion of a first mechanical interlock supports the bottom face of the bottom portion of a second mechanical interlock when enclosures on which the first and second mechanical interlocks are attached are vertically aligned and stacked.

3. The disk drive enclosure of claim 1, wherein each of the first and second plurality of mechanical interlocks has portion having a surface complementary to a surface of a support in a rack, such that the portion of the mechanical interlock and the support in the rack are slidably connectable in a first direction and when connected prohibit movement of the mechanical interlock with respect to support in second and third directions orthogonal to the first direction.

4. The disk drive enclosure of claim 1, further comprising:

a locking mechanism having a first movable member mounted on the first side of the housing.

5. A disk drive enclosure for mounting in a rack having a support, comprising:

a housing for enclosing a disk drive;

a first plurality of mechanical interlocks mounted on a first side of the housing;

a second plurality of mechanical interlocks mounted on a second side of the housing opposite the first side of the housing;

wherein each of the first and second plurality of mechanical interlocks has portion having a surface complementary to a surface of the support in the rack, such that the portion of the mechanical interlock and the support in the rack are slidably connectable in a first direction and when connected prohibit movement of the mechanical interlock with respect to support in second and third directions orthogonal to the first direction.

6. A mechanical interlock for use with a disk drive enclosure comprising a top portion, a bottom portion and a section connecting the top portion to the bottom portion, wherein the top portion has a surface complementary to a surface of the bottom portion, such that the top portion of a first mechanical interlock and the bottom portion of a second mechanical interlock are slidably connectable in a first direction and when connected prohibit movement of the mechanical interlocks with respect to each other in a second and directions orthogonal to the first direction.

7. The mechanical interlock of claim 6, wherein the top portion has top face and the bottom portion has a bottom face such that the top face of the top portion of a first mechanical interlock supports the bottom face of the bottom portion of a second mechanical interlock when enclosures on which the first and second mechanical interlocks are attached are vertically aligned and stacked.

8. A rack mount for a disk drive enclosure having at least one bay for receiving the disk drive enclosure, and comprising:

a support mechanism having edges shaped to engage an interlock on the disk drive enclosure to guide the disk drive enclosure into the bay;

a spring loaded block shaped to engage the interlock on the disk drive enclosure so as to permit the interlock to pass the blocks in a first direction and to prohibit passage of the interlock in a second direction opposite the first direction; and

a user-operable member constructed to move the spring loaded block to permit passage of the interlock in the second direction to permit removal of the disk drive enclosure from the rack mount.
