Abstract

An apparatus comprising a disk drive assembly and a disk drive cage for selectively receiving the disk drive assembly. The disk drive assembly includes first and second side rails secured to opposing sides of a disk drive, wherein the first side rail includes a distal end having a distally-opening slot configured to receive a rigid structure, such as a bent portion of the cage, fixedly extending from the disk drive cage. The slot in the first side rail enables the disk drive assembly to distally advance to a fully installed position within the disk drive cage. Incompatible disk drive assemblies do not include such a slot and are prevented from reaching the fully installed position. Preferably the distal end of first side rail extends beyond the distal end of the disk drive.

Claims

1. An apparatus comprising:

a disk drive assembly including first and second side rails secured to opposing sides of a disk drive; and

a disk drive cage for selectively receiving the disk drive assembly, wherein the first side rail includes a distal end having a distally-opening slot configured to receive a rigid structure fixedly extending from the disk drive cage, and wherein the slot in the first side rail enables the disk drive assembly to distally advance to a fully installed position within the disk drive cage.

2. The apparatus of claim 1, wherein the rigid structure is a bent portion of the cage.

3. The apparatus of claim 1, wherein the disk drive assembly includes a first latch member that aligns with a mating latch member of the disk drive cage when the disk drive assembly reaches the fully installed position

4. The apparatus of claim 1, wherein the second side rail includes a distal end having a slot configured to receive the rigid structure fixedly extending from the disk drive cage, and wherein the slot in the second side rail enables the disk drive assembly to advance to a fully installed position within the disk drive cage.

5. The apparatus of claim 1, wherein the second side rail includes a distal end that does not having a slot configured to receive the rigid structure, and wherein the absence of a slot in the second side rail only prevents the disk drive assembly from advancing to a fully installed position unless the disk drive assembly is oriented with the distally-opening slot of the first side rail aligned to receive the rigid structure.

6. The apparatus of claim 1, wherein the disk drive cage forms opposing channels for slidably receiving the first and second side rails.

7. The apparatus of claim 1, wherein the distal end of first side rail extends beyond the distal end of the disk drive.

8. The apparatus of claim 7, wherein the second side rail has a distal end extending beyond the distal end of the disk drive.

9. The apparatus of claim 8, wherein the distal ends of the first and second side rails are inwardly angled.

10. The apparatus of claim 1, wherein the disk drive is a hard disk drive.

11. An apparatus comprising:

a disk drive cage for selectively receiving the disk drive assembly, wherein the disk drive cage includes a rigid structure fixedly extending from the disk drive cage; and

a disk drive assembly including a distal end having a distally-opening slot configured to receive the rigid structure, and wherein the slot enables the disk drive assembly to distally advance to a fully installed position within the disk drive cage.

12. The apparatus of claim 11, wherein the disk drive assembly includes a first latch member that aligns with a mating latch member of the disk drive cage when the disk drive assembly reaches the fully installed position

13. The apparatus of claim 11, wherein the rigid structure and the slot are configured to prevent the disk drive assembly from distally advancing to the fully installed position unless the disk drive assembly is oriented correctly

14. The apparatus of claim 11, wherein the disk drive is a hard disk drive.

15. The apparatus of claim 11, wherein the rigid structure extends inwardly from along a top or bottom of the disk drive cage.

16. The apparatus of claim 11, wherein the rigid structure is securedly attached to the cage.

17. A method comprising:

securing a disk drive cage in a chassis or rack having a computer system compatible with certain disk drive assemblies;

providing the disk drive cage with an inwardly extending fixed rigid structure positioned to align with disk drive assemblies being installed in disk drive cage;

configuring compatible disk drive assemblies to include a distally-opening slot aligned to receive the rigid structure;

selectively receiving a compatible disk drive assembly into a fully installed position within the disk drive cage, wherein the distally-opening slot of the compatible disk drive assembly receives the rigid structure; and

preventing an incompatible disk drive from being selectively received into a fully installed position within the disk drive cage due to contact with the rigid structure, wherein the incompatible disk drive assembly is not configured with a distally-opening slot aligned to receive the rigid structure.

18. The method of claim 17, further comprising:

selectively latching a disk drive assembly into the disk drive cage only when the disk drive assembly reaches the fully installed position.

19. The method of claim 17, wherein a latch element on the disk drive assembly can only engage a mating latch element on the disk drive cage when the disk drive assembly is in the fully installed position.

20. The method of claim 17, wherein the step of configuring compatible disk drive assemblies to include a distally-opening slot includes securing first and second side rails to opposing sides of a compatible disk drive, wherein the first side rail includes a distal end having a distally-opening slot configured to receive the rigid structure as the disk drive assembly advances to the fully installed position.
