Description

Expansion assembly, data cabinet system and method for expanding data cabinet

Technical Field

The present disclosure relates to an expansion assembly for a data enclosure, a data enclosure system including a data enclosure and an expansion assembly, and a method for expanding a data enclosure.

Background

With the development of cloud computing and cloud storage industries, data storage and data exchange requirements are receiving increasing attention. New data centers are being built continuously or original data centers are being expanded to cope with enormous data processing demands. Data cabinets are typically disposed in data centers for housing servers or data storage devices and associated wiring harnesses. The server or data storage device is connected to each large terminal device or to a power source via a large number of cables. In addition, a significant amount of heat is typically generated during operation of the data center, and therefore, it is also often necessary to provide cooling systems in the data cabinets that in turn require additional space for placement of cooling lines. Liquid-cooled servers are commonly provided in the prior art to address the above-mentioned problems.

In the initial stage of the construction of a new data center infrastructure, the service and the demand are often not very clear, the specification and the model of the server are often not determined, and once the demand is determined, the production and deployment time of the data cabinet is often short, so that the demand of quick delivery cannot be met. However, in order to be able to provide sufficient space for the installation of subsequent equipment, if a larger data cabinet is provided, this may result in a waste of valuable machine room space in the data center and an increase in the cost of the data cabinet itself. In addition, as old data centers are expanded, the data cabinets may need to be fixed with increased wiring harnesses as functionality expands, or to provide power and cooling functions to newly added servers or storage devices, however, the structural space of the old data cabinet system may not have been able to meet the setup and additional wiring harnesses of new servers, such as liquid cooled servers.

An expansion assembly 1, a data enclosure system 100, and a method for expanding a data enclosure according to embodiments of the present disclosure are illustrated next in connection with fig. 1-4.

Referring to fig. 1, a data enclosure system 100 is shown in an assembled state according to one embodiment of the present disclosure. The data enclosure system 100 may have one data enclosure 1. The data cabinet 1 may have a frame structure. The frame structure may have side rails, for example made of profile material, on each of its edges, namely twelve edges, which are connected to one another at the ends. In the vertical position, mounting bars are provided on the sides of the data cabinet 1 for fixing and mounting devices, such as servers or switches, respectively. In fig. 1, the mounting bar may be a beam member connecting two vertically extending side beams, and thus the server may be supported on at least two beam members. However, it is also conceivable to provide at least two beam members with substantially horizontally extending plate-like members, on which plate-like members then servers or exchanges can be placed. Due to the frame-shaped structure of the data cabinet 1, for example, servers or switches can be placed into the data cabinet 1 from any one side of the data cabinet 1 and supported on the respective cross members or plate-like members, as long as this side is not covered by other data cabinets or covers in the use state.

In fig. 1, an expansion module 2 can be arranged on two opposite sides of the data cabinet 1, wherein, for clarity, the expansion module 2 in fig. 1 has only an expansion frame, i.e. no further components such as a mounting plate 5 and an adapter unit are provided on the expansion module 2. The extension assembly 2 can be detachably fastened to the side of the data cabinet 1 in the use state, for example to a side rail of the data cabinet 1. However, it is also conceivable that the expansion assembly 2 is placed only beside the side of the data cabinet 1 and is not mechanically connected to the data cabinet 1. In an embodiment not shown, the data enclosure may be configured with only one unique expansion component.

Referring to fig. 2, a data enclosure 1 is shown along with an expansion assembly 2 shown separately to the left of the data enclosure 1. The expansion assemblies 2 on the right side of the data cabinet 1 may be identically constructed, or similarly constructed, or differently constructed. The left expansion module 2 will be described below as an example. It goes without saying that the description relating thereto also applies to the right-hand expansion module 2. It can be seen that the expansion assembly 2 has an expansion frame. In particular, the width of the extension frame of the extension assembly 2 in the X-direction and the height of the extension frame in the Z-direction may be adapted to the width of the data cabinet 1 in the X-direction and the height in the Z-direction, thereby achieving an attractive and uniform appearance when the extension assembly 2 is arranged at the data cabinet 1. As can also be seen in fig. 2, the extension frame of the extension module 2 has first frame plates 15 which are opposite one another and extend in the height direction or in the Z direction, and second frame plates 16 which are opposite one another and extend in the width direction or in the X direction, each second frame plate 16 connecting two first frame plates 15 to one another. In the embodiment shown in the figures, the expansion assembly 2 is open. It is conceivable that the opening of the expansion assembly 2 facing away from the data cabinet 1 can be closed with a cover plate, not shown.

For a clearer illustration of the expansion assembly 2, see fig. 3, a partial perspective view of the expansion assembly 2 is shown. It can be seen that on each side of the extension frame of the extension assembly 2, i.e. on each first frame plate 15, two parallel vertically extending mounting bars 3 can be mounted. The mounting strip 3 has a plurality of first engagement points 4 that are successive in the height direction or in the Z direction, so that the mounting plate 5 can be selectively engaged on the first engagement points 4. The selective engagement of the mounting plate 5 on the first engagement point 4 means that the engagement position of the mounting plate 5 in the height direction or in the Z direction of the mounting bar 3 is adjustable or selectable. The mounting plate 5 may be engaged on any one of the first engagement portions 4 by means of a hook, or the mounting plate 5 may be engaged on any one of the first engagement portions 4 by means of a fastener. An adapter unit can then be arranged on the mounting plate 5, whereby the position of the adapter unit in the height direction or in the Z direction of the mounting bar 3 is indirectly adjustable. In the case of a multipoint positioning of the mounting plate 5 on the mounting strip 3, the mounting plate 5 can be engaged by means of at least two hooks on at least two mating first engagement points 4. In the embodiment shown, the mounting plate 5 engages with two first engagement points 4 of the two mounting bars 3 at its four corners, for example by means of four screws. In the mounted state, the mounting plate 5 may extend horizontally in the Y direction.

Each adapter unit can be mounted to the extension frame, in particular to the vertically extending first frame plate 15 of the extension frame, by means of at least one mounting plate 5, for example by means of one single mounting plate 5 or by means of two or three mounting plates 5.

Alternatively, the adapter unit may be directly engaged on the first engagement site 4 by means of a hook, or the adapter unit may be directly engaged on the first engagement site 4 by means of a fastener, such as a screw, whereby the mounting plate 5 may be omitted.

Referring to fig. 3, the mounting plate 5 has a plurality of second engagement portions 6 distributed in the depth direction or in the Y direction, and the adapter unit is selectively engageable with at least one of the second engagement portions, so that the adapter unit is selectively engageable on the mounting plate 5 in the depth direction or in the Y direction along the mounting plate 5. The position of the adapter unit can thus be adjusted in both directions (i.e. in the height direction or in the Z direction along the mounting bar 3 and in the depth direction or in the Y direction along the mounting plate 5). The adapter unit can be engaged here on the second engagement site 6 by means of a hook or the adapter unit can be engaged on the second engagement site 6 by means of a fastener.

Referring to fig. 3, one of the adaptation units may be a cooling fluid distribution unit 7, the cooling fluid distribution unit 7 having an inflow main pipe 9 and an outflow main pipe 10, the inflow main pipe 9 and the outflow main pipe 10 being configured for forming a cooling cycle for devices in the data cabinet, wherein the inflow main pipe 9 has a plurality of first fluid interfaces 13 distributed in its height direction or in Z direction, the first fluid interfaces 13 being configured for supplying cooling fluid to the devices in the data cabinet, the outflow main pipe 10 has a plurality of second fluid interfaces 14 distributed in its height direction or in Z direction, the second fluid interfaces 14 being configured for pooling cooling fluid absorbing heat of the devices in the data cabinet into the outflow main pipe. One end of a first hose line 11 leading from the first fluid connection 13 is connected to said first fluid connection 13, while the other end of the first hose line 11 is connected to the equipment in the data cabinet 1. One end of the second hose conduit 12 leading from the second fluid port 14 is connected to said second fluid port 14, while the other end of the second hose conduit 12 is connected to equipment in the data cabinet 1. Due to the uncertainty of the position of the devices located in the data cabinet 1 in the height direction, or in the Z direction and in the depth direction, or in the Y direction, of the data cabinet 1, by adjusting the position of the cooling fluid distribution unit 7 in the expansion frame of the expansion assembly 2, a flexible positional adjustability can be achieved, which makes it possible to optimally adapt the position of the cooling fluid distribution unit 7 to the devices in the data cabinet and to bend the first hose line 11 and the second hose line 12 as little as possible, so that possible damage to the first hose line 11 and the second hose line 12 is avoided, and on the other hand, the required lengths of the first hose line 11 and the second hose line 12 are as short as possible, which results in as little cooling power dissipation of the cooling fluid during transport. It is also pointed out in fig. 3 that the first hose line 11 and the second hose line 12 are independent of each other, and that only the other end of the first hose line 11 is visible in fig. 3, while the other end of the second hose line 12 is obscured by the first frame plate 15 of the extension frame 2 for viewing reasons and is therefore not visible.

It can also be seen in fig. 3 that the main pipes as inflow main pipe 9 and outflow main pipe 10 are both arranged on the left side of the expansion frame of the expansion assembly 2, so that the first hose pipe 11 and the second hose pipe 12 can extend in the interior space of the expansion frame, starting from the side of the main pipe (inflow main pipe 9 and outflow main pipe 10) on which they are located, first towards the opposite side of the expansion frame and then in the middle space of the expansion frame curve in the direction of the devices of the data cabinet 1 and thus open out to the devices in the data cabinet 1.

Alternatively, the main pipes as the inflow main pipe 9 and the outflow main pipe 10 may be adjusted according to the positions of the cooling fluid input interface and the cooling fluid output interface of the devices of the data cabinet 1, for example, may be both disposed on the right side of the expansion frame of the expansion assembly 2.

In the embodiment shown in fig. 3 and 4, the inflow main pipe 9 and the outflow main pipe 10 are both arranged on the same side of the expansion assembly 2, so that both the first hose pipe 11 and the second hose pipe 12 leading out from the main pipes (inflow main pipe 9 and outflow main pipe 10) extend into the data cabinet 1 in the intermediate space of the expansion frame of the expansion assembly away from this side. As can be seen from fig. 4, a power supply distribution unit 8 is provided on the other side opposite the cooling fluid distribution unit 7. The power supply distribution unit 8 can be arranged in a similar manner to the cooling fluid distribution unit 7 on the opposite other side of the expansion frame of the expansion assembly 2 and thus enables flexible positional adjustability, which is not described in detail here. Additionally, a spacer may be provided between the cooling fluid distribution unit 7 and the power distribution unit 8.

The power distribution unit 8 may be configured as a power strip comprising a plurality of side-by-side groups of jacks, for example each group of jacks may have three jacks, with each group of jacks being capable of being plugged into a plug having three pins.

In addition to the embodiments shown above, in some not shown embodiments, the cooling fluid input interfaces or cooling fluid output interfaces of the devices in the data cabinet 1 are respectively closer to opposite sides of the expansion frame of the expansion assembly 2. In such a case, the inflow main pipe 9 and the outflow main pipe 10 of the cooling fluid distribution unit 7 may be respectively provided on opposite sides of the expansion frame. More specifically, if the cooling fluid input interface of the equipment in the data cabinet 1 is closer to the first side of the expansion frame, the input main conduit 9 of the cooling fluid distribution unit 7 may be arranged on a second side of the expansion frame opposite to the first side in such a way as to be able to provide a suitable bending space for the first hose conduit 11 connecting the cooling fluid input interface and the inflow main conduit 9 and at the same time provide a shorter hose conduit length. In such an embodiment, the cooling fluid output interface of the equipment in the data cabinet 1 is closer to the second side of the expansion assembly 2, so the outflow main pipe 10 of the cooling fluid distribution unit 7 may be arranged on the first side of the expansion frame opposite to the second side. In such an embodiment, the power distribution unit may not be provided, as the main conduit is arranged on both opposite sides of the expansion assembly 2. However, it is also conceivable that the power distribution unit 8 may be arranged above the cooling fluid distribution unit 7 and spaced apart from the cooling fluid distribution unit 7 by means of a spacer.

In addition to the embodiments shown above, in some not shown embodiments, a wire tying plate or wire-tying slot may be provided in the expansion assembly 2, whereby the wire harness that is exposed to the data cabinet 1 may be fixed and organized.

The data enclosure 1 may be flexibly expanded using the expansion assembly 2 of the present disclosure to form a data enclosure system 100. Accordingly, the present disclosure also relates to a method of expanding a data enclosure 1. The method comprises the following steps:

s1: providing a data cabinet 1;

s2: at least one expansion assembly 2 is arranged at least one side of the data cabinet 1, wherein the expansion assembly 2 comprises an expansion frame and a mounting bar 3 mounted to the expansion frame.

S3: at least one adapter unit is configured for a data rack and/or for a device in a data rack and is mounted to the mounting bar 3 by means of a mounting plate 5, wherein the adapter unit has a mounting position that is adjustable in the depth direction or in the Y direction along the mounting plate 5 and the mounting plate 5 has a mounting position that is adjustable in the height direction or in the Z direction along the mounting bar 3.

In some embodiments, in step S1, the data enclosure 1 may be an existing data enclosure.

In some embodiments, step S2 comprises: the extension frame of the at least one extension assembly 2 is fixedly mounted on a corresponding side of the data cabinet.

In some embodiments, the expansion assembly and expandable data enclosure system of the present disclosure and method of expanding a data enclosure system may have, but are not limited to, some or all of the following advantages:

(1) The data center can firstly utilize standard data cabinet stock construction, and at least one expansion component can be flexibly arranged according to the actual condition of the data cabinet in the data center, so that the flexibility of arranging a data cabinet system is improved, the construction efficiency of a machine room is improved, and the construction period of the machine room is shortened.

(2) Only the data cabinets to be expanded can be expanded, and all the data cabinets in the data center are not required to be expanded, so that precious data center space is saved, and meanwhile, the arrangement cost of a data cabinet system is reduced, and therefore the cost of the whole data center is reduced.

(3) The existing data center can be conveniently modified. For example, because of business requirements, a certain data enclosure in an existing data center may require equipment to be adjusted or added, but the existing data enclosure may not be sufficiently space to accommodate the equipment to be installed, and the existing data enclosure may be expanded with an expansion component.

The present disclosure may include any feature or combination of features disclosed herein either implicitly or explicitly or any generalisation thereof, and is not limited to any of the defined ranges as set forth above. Any of the elements, features, and/or structural arrangements described herein may be combined in any suitable manner.

The particular embodiments disclosed above are illustrative only, as the disclosure may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified and all such variations are considered within the scope and spirit of the disclosure.
