Abstract

Embodiments generally relate to a optimizing the design of a chassis, such that the chassis features a different width front end hard disk drive module. Key components of the design include chassis flexibility for different hard drive quantities, and sliding rails which can be installed for sliding the chassis in and out of the rack, taking into account the housing contours of both the chassis and the front end hard disk drive module of different width. The rails can be reinforced with different backing materials for improved load support. The sliding rails include an inner set of rails attached to the chassis, and an outer set of rails which extend along the housing of both the chassis and the hard disk drove module.

Claims

1. A chassis, comprising:

a housing comprising a front portion and a rear portion along the length of the housing, a width of the front portion greater than a width of the rear portion ; and

a first and second set of rails attached to the housing adapted for attachment to a rack, each set of rails comprising;

a first rail attached to the housing and extending along the length of the second portion,

a second rail slidably engaging the first rail and extending along the length of the second portion, and

at least one support piece attached to the second rail and extending at least along a length of the first portion, the at least one support piece dimensioned to accommodate the width of the first portion when the first rail and the second rail are in an non-extended arrangement.

2. The chassis of claim 1, further comprising a third rail slidably engaging the first rail and the second rail and extending along the length of the second portion.

3. The chassis of claim 1, wherein the at least one support piece comprises a front support piece and a rear support piece, the front support piece adapted for the accommodating of the width of the first portion when the first rail and the second rail are in a non-extended arrangement.

4. The chassis of claim 3, wherein the front support piece further comprises a reinforcing component.

5. The chassis of claim 4, wherein the reinforcing component is located between two discontinuous flange walls on the front support piece.

6. The chassis of claim 4, wherein the reinforcing component comprises ribs.

7. The chassis of claim 4, wherein the reinforcing component comprises a metal plate.

8. The chassis of claim 3, wherein the front support piece comprises first and second flange portions, and wherein each of the first and second flange portions comprises a flange wall.

9. The chassis of claim 8, wherein the flange walls of the first and second flange portions face in opposite directions.

10. The chassis of claim 1, wherein the first portion comprises a hard disk drive module.

11. The chassis of claim 1, wherein the first and second set of rails further comprise a rear support portion attaching to the rack.

12. A chassis adapted to be slidably attached to a rack, comprising:

a chassis comprising a front portion and a rear portion along the length of the housing, wherein the front portion is wider than the rear portion; and

a first and second set of rails attached to the housing adapted for attachment to a rack, each set of rails comprising;

a first rail attached to the housing and extending along the length of the second portion,

a second rail slidably engaging the first rail and extending along the length of the second portion,

a third rail slidably engaging the first rail and the second rail and extending along the length of the second portion, and

at least one support piece attached to the second rail and extending at least along a length of the first portion, the at least one support piece dimensioned to accommodate the width of the first portion when the first rail and the second rail are in a non-extended arrangement.

13. The chassis of claim 12, wherein the at least one support piece comprises a front support piece and a rear support piece, the front support piece adapted for the accommodating of the width of the first portion when the first rail and the second rail are in a non-extended arrangement.

14. The chassis of claim 13, wherein the front support piece further comprises a reinforcing component.

15. The chassis of claim 14, wherein the reinforcing component is located between two discontinuous flange walls on the front support piece.

16. The chassis of claim 14, wherein the reinforcing component comprises ribs.

17. The chassis of claim 14, wherein the reinforcing component comprises a metal plate.

18. The chassis of claim 13, wherein the first portion comprises a hard disk drive module.

19. A chassis adapted to be slidably attached to a rack, comprising:

a chassis comprising a front portion and a rear portion along the length of the housing, wherein the front portion is wider than the rear portion; and

a first and second set of rails attached to the housing adapted for attachment to a rack, each set of rails comprising;

a first rail attached to the housing and extending along the length of the second portion,

a second rail slidably engaging the first rail and extending along the length of the second portion,

a third rail slidably engaging the first rail and the second rail and extending along the length of the second portion, and

at least one support piece attached to the second rail and extending at least along a length of the first portion, wherein the at least one support piece dimensioned to accommodate the width of the first portion when the first rail and the second rail are in an non-extended arrangement, and wherein the at least one support piece comprises a front support piece and a rear support piece, the front support piece adapted for the accommodating of the width of the first portion when the first rail and the second rail are in a non-extended arrangement.

20. The chassis of claim 19, wherein the reinforcing component is located between two discontinuous flange walls on the front support piece.

21. The chassis of claim 19, wherein the reinforcing component comprises ribs.

22. The chassis of claim 19, wherein the reinforcing component comprises a metal plate.

23. The chassis of claim 19, wherein the front support piece comprises first and second flange portions, and wherein each of the first and second flange portions comprises a flange wall.

24. The chassis of claim 23, wherein the flange walls of the first and second flange portions face in opposite directions.

25. The chassis of claim 19, wherein the first portion comprises a hard disk drive module.
