Abstract

A method for designing and assembling a modular IT rack includes a manufacturer designing and constructing lightweight, modular corrugated cardboard modules/segments and corresponding banding and corner components that can be used to assemble the modular IT rack. A user/assembler of the modular IT rack assembles modular tray grouping and enclosure (MTGE) casing units using a first set of cardboard modules. The user constructs trays using a second set of cardboard modules. The user affixes cable support components to the sides of sub-groups of the constructed trays. The user encloses sub-groups of trays having the affixed cable support components within the assembled MTGE casing units to create MTGE blocks. The user vertically stacks the MTGE blocks having the tray sub-groups and the affixed cable support components enclosed within. The user aligns and secures the vertically stacked MTGE blocks in a fixed position using banding and corner components.

First claim

What is claimed is:

1. A modular information technology (IT) rack assembly for physically supporting at least one electronic component of an information handling system (IHS), the rack assembly comprising:
a stacked arrangement of modular tray grouping and enclosure (MTGE) blocks, each MTGE block having:
an exterior perimeter casing providing a volumetric, vertical space with lateral sides defining an interior space extending between a front opening and a rear opening of the casing, the casing created with defined foldable corners/edges that enable the casing to be flat packed for shipping and then reconfigured via the lateral sides to a vertical orientation that provides the volumetric space; and
a plurality of trays comprised of a lightweight material constructed with a contiguous surface material having foldable corners/edges that enable the tray to be (i) flat packed and (ii) extendable into a rectangular shaped volume within which an IT gear can be inserted, wherein the plurality of trays are stacked vertically within the volumetric, vertical space of the exterior perimeter casing;

a plurality of corner components positioned vertically at each of four corners of the stacked arrangement of mini rack modules and which provides vertical rigidity to the rack assembly; and
at least one banding component that extends horizontally around the perimeter of the stacked arrangement of mini rack modules to fixably hold each of the corner components in place and provide lateral support for the rack structure; and
wherein the at least one banding component and the plurality of corner components are positioned to respectively provide structural stability in a horizontal plane and vertical rigidity in a vertical plane.

2. The rack assembly of claim 1 , further comprising:
at least one cable management support component integrated into an external flange of the exterior perimeter casing.

3. The rack assembly of claim 1 , further comprising:
at least one air flow management ducting component attached to a rear of the modular IT rack assembly and which supports hot aisle and cold aisle separation.

4. The rack assembly of claim 3 , wherein:
the at least one air flow management ducting components includes a baffle having a plurality of air flow directing (AFD) sections that have flanges which direct exhaust air flow from heat dissipating IT gear located within the volumetric vertical space of the modular IT rack assembly; and
the baffle is attached to a rear section of the chassis of the modular IT rack system, wherein the AFD sections fold inward to be adhered to the rear section and to separate the cold air section from the hot exhaust air section.

5. The rack assembly of claim 1 , wherein:
the MTGE blocks, the trays and the perimeter casing are assembled using flat-packed cardboard modules that are constructed using a composite material, wherein the modules include at least one of (a) adhesive sections and (b) corrugated sections.

6. The rack assembly of claim 1 , wherein the corner components are substantially vertically running brackets positioned against an outer surface of the MTGE unit to provide alignment for the stacked MTGE blocks and further comprise:
first corner components which have flanges that are inserted into grooves provided within the cable support components; and
second corner components that are substantially 90 degree brackets that are physically abutted to an outer corner surface of side panels of the MTGE unit and to back panels of the rack assembly.

7. The rack assembly of claim 1 , further comprising:
horizontal panels which include:
intermediate horizontal panels placed between adjacent MTGE blocks;
top and bottom horizontal panels that provide a protective exterior surface enclosure for the MTGE blocks; and
wherein the intermediate horizontal panels and the bottom horizontal panel are weight-bearing panels that provide additional support for the weight of the internal components.

8. The rack assembly of claim 1 , wherein:
the banding component are extended around a horizontal panel and placed between vertically adjacent cable support extensions.

9. An information handling system (IHS) comprising:
at least one electronic component; and
a stacked arrangement of modular tray grouping and enclosure (MTGE) blocks, each MTGE block having:
an exterior perimeter casing providing a volumetric, vertical space with lateral sides defining an interior space extending between a front opening and a rear opening of the casing, the casing created with defined foldable corners/edges that enable the casing to be flat packed for shipping and then reconfigured via the lateral sides to a vertical orientation that provides the volumetric space; and
a plurality of trays comprised of a lightweight material constructed with a contiguous surface material having foldable corners/edges that enable the tray to be (i) flat packed and (ii) extendable into a rectangular shaped volume within which an IT gear can be inserted, wherein the plurality of trays are stacked vertically within the volumetric, vertical space of the exterior perimeter casing;

a plurality of corner components positioned vertically at each of four corners of the stacked arrangement of mini rack modules and which provides vertical rigidity to the rack assembly;
at least one banding component that extends horizontally around the perimeter of the stacked arrangement of mini rack modules to fixably hold each of the corner components in place and provide lateral support for the rack structure; and
wherein the at least one banding component and the plurality of corner components are positioned to respectively provide structural stability in a horizontal plane and vertical rigidity in a vertical plane.

10. The IHS of claim 9 , wherein the rack assembly further comprises:
at least one cable management support component integrated into an external flange of the exterior perimeter casing.

11. The IHS of claim 9 , wherein the rack assembly further comprises:
at least one air flow management ducting component attached to a rear of the modular IT rack assembly and which supports hot aisle and cold aisle separation.

12. The IHS of claim 11 , wherein:
the at least one air flow management ducting components includes a baffle having a plurality of air flow directing (AFD) sections that have flanges which direct exhaust air flow from heat dissipating IT gear located within the volumetric vertical space of the modular IT rack assembly; and
the baffle is attached to a rear section of the chassis of the modular IT rack system, where the AFD sections fold inward to be adhered to the rear section and to separate the cold air section from the hot exhaust air section.

13. The IHS of claim 9 , wherein:
the MTGE blocks, the trays and the perimeter casing are assembled using flat-packed cardboard modules that are constructed using a composite material, wherein the modules include at least one of (a) adhesive sections and (b) corrugated sections.

14. The IHS of claim 9 , wherein the corner components are substantially vertically running brackets positioned against an outer surface of the MTGE unit to provide alignment for the stacked MTGE blocks and further comprise:
first corner components which have flanges that are inserted into grooves provided within the cable support components; and
second corner components are substantially 90 degree brackets that are physically abutted to an outer corner surface of side panels of the MTGE unit and to back panels of the rack assembly.
