The present disclosure relates generally to a modularized front window of a server system. More particularly, aspects of this disclosure relate to a unified chassis having front window bays with the same dimensions, and configured to accept one or more device trays, with each tray adapted for holding a different device type.
Servers are specialized computer systems including numerous electronic components that are integrated in a single unit using a server chassis. For example, servers can be dedicated for storage, computation, or audio-visual media purposes. Such purposes often determine the components mounted in the server chassis. In addition, servers have evolved to having different form factors. An early design, still in use today, is a tower case. Rackmount servers were introduced after the tower design and, more recently, blade servers have been implemented. The rackmount server can be generally described as a rectangular box, where each server can be placed in a rack horizontally. This form factor offers advantages over a tower case in space savings, which generally require a table top or cabinet. Blade servers can provide additional space savings and can be useful, particularly where some components, such as power supplies and cooling fans, can be shared among different blade servers.
Although there are some non-standard sizes, server rack heights are classified by rack units “U” where one “U” is equal to 1.75 inches. The total rack heights can vary, for example, from as little as 4 U to 42 U. Rackmount servers are designed to fit into slots or racks of the server rack. The slot or rack height can be sub-divided into multiple “U” units to accommodate different server heights, such as 1 U, 2 U, 3 U, and 4 U. Other dimensions of the server rack are referred to by standard units, such as inches. A standard width of a server rack, for example, is 19 inches. Typically, servers range from 24 to 48 inches in depth. Some server racks are also designed to accommodate more than one type of server form factor (e.g., tower case, rackmount, and blade server). Peripherals, such as input/output devices (e.g., monitor, keyboard, mouse), clips for cable management, and the like, can also be accommodated by the server rack design.
The server rack therefore is designed to be modular, where different server sizes and form factors can be accommodated. This allows for the changing of servers mounted in a server rack for maintenance, or for the changing needs for a server system accommodating multiple servers. Although offering some flexibility, the standard systems do not provide modularization at the device level, as illustrated with reference to
With the current design, multiple chassis are needed when different devices are desired. An existing chassis cannot be easily re-purposed for a different use, such as from a memory storage server to a computation server. Likewise, an existing chassis cannot be easily augmented with an upgraded device, such as swapping a 3.5 inch Hard Disk Drive (HDD) with a 2.5 inch HDD or a Solid State Drive (SSD). When assembling a new server system, an inventory of different chassis types is therefore needed to accommodate using different components. Furthermore, a combination of components having different form factors, such as the devices 104 and 106, cannot be accommodated by a single chassis.
Thus, there is a need for a unified chassis system that can accommodate different types of devices. It would be desirable for the devices to be easy to interchange in the chassis and require no re-design. Such a system would provide improvements in cost and efficiency to server designs.

A first implementation of the disclosure is a modular server system. The modular server system includes a server chassis having one or more window bays, with each having the same dimensions. This implementation also includes a plurality of device trays, each for holding a device. The device is selected from different devices, and each device tray fits in the one or more window bays.
Optionally, at least a first device selected from the plurality of devices has a form factor that is different from a form factor of a second device selected from the devices. Optionally, the device is a member of a group of devices, wherein each device in the group of devices have the same form factor. In some implementations, one device tray includes a device carrier for coupling a device with the device tray. The device is optionally selected from one or more of a hard disk drive (HDD), a solid state drive (SSD), a Graphics Processing Unit (GPU), and a ruler device.
In some implementations, the device tray comprises one or more device slots having interior surfaces defining an interior space for placement of the device.

Optionally, the interior space is defined by a top interior surface, a bottom interior surface, and a spacer interior surface.
In some implementations of the system, the window bays include a window horizontal width about equal to a device tray width; a window vertical height about equal to a device tray height; and a window depth about equal to or less than the device tray depth. An aperture in the chassis is defined by the window horizontal width and window horizontal height. The aperture allows slide-in placement of the device trays in each of the window bays. Slide-in placement is by engagement of one or more of an inner surface of the widow bay, a rail of the window bay, a groove of the window bay, and a fastener. Optionally, the sever chassis includes a top cover which can be removed for placement of device trays in the window bays.
In some implementations of the modular server system, the server chassis includes a rackmount server form factor having a width, a height, and a depth. The server chassis further includes a plurality of front windows in the plane defined by the width and the height. Each front window includes an aperture having a horizontal width and vertical height. The aperture is positioned in a front of the chassis, and defines an opening to one of the window bays. At least two of the apertures define a row of window openings. Each aperture in the row of window openings is arrayed in the direction of the width, and aligned in the vertical height and the horizontal width to each other. Optionally, the number of window openings in the row of window openings is 1 to 10.
In some implementations of the modular server system, the server chassis includes a rackmount server form factor having a width, a height, and a depth. The server chassis further includes a plurality of front windows in the plane defined by the width, and the height. Each front window includes an aperture having a horizontal width and vertical height. The aperture is positioned in a front of the chassis, and defines an opening to one of the window bays. At least two of the apertures define a column of window openings. Each aperture in the column of window openings is arrayed in the direction of the height, and is aligned in the vertical height and the horizontal width to each other. Optionally the number of window openings in the column of window openings is 1 to 10.
In yet other implementations of the modular server system, the server chassis includes a rackmount server form factor having a width, a height, and a depth. The server chassis further includes a plurality of front windows in the plane defined by the width, and the height. Each front window includes an aperture having a horizontal width, and vertical height. The aperture is positioned in a front of the chassis, and defines an opening to one of the window bays. At least two of the apertures define a row of window openings. Each aperture in the row of window openings is arrayed in the direction of the width, and is aligned in the vertical height, and the horizontal width to each other. At least two of the apertures define a column of window openings. Each aperture in the column of window openings is arrayed in the direction of the height, and is aligned in the vertical height and the horizontal width to each other. Optionally, the number of window openings is 3-100.
A second implementation of the disclosure is a device tray for holding a device. The device tray has one or more device slots having interior surfaces defining a space for placement of a device. The device tray also includes a front aperture for slide-in placement of the device; a back aperture for connecting the device to at least a second device; and a fastener for holding the device in the device slot. Optionally, the device tray further has a top including an opening from an outer top surface to the inner top surface. Optionally, the opening is configured as a slit or a round hole. In some implementations, the device tray includes a first part of a fastening mechanism. The device includes a second part of a fastening mechanism. The first part of the fastening mechanism, and the second part of the fastening mechanism, can be engaged when the device is in the device slot. When engaged, the fastening mechanism fastens the device to the device tray. In some implementations, the interior space is defined by at least a top interior surface, a bottom interior surface, and a spacer interior surface.
The implementations according to the disclosure herein provide a unified chassis system that can accommodate different devices. Devices can be easily interchanged in the chassis providing improvements in cost and efficiency to server designs.

The present disclosure is an example or illustration of the principles of the present disclosure, and is not intended to limit the broad aspects of the disclosure to the embodiments illustrated. To that extent, elements, and limitations that are disclosed, for example, in the Abstract, Summary, and Detailed Description sections, but not explicitly set forth in the claims, should not be incorporated into the claims, singly or collectively, by implication, inference, or otherwise. For purposes of the present detailed description, unless specifically disclaimed, the singular includes the plural and vice versa; and the word “including” means “including without limitation.” Moreover, words of approximation, such as “about,” “almost,” “substantially,” “approximately,” and the like, can be used herein to mean “at,” “near,” or “nearly at,” or “within 3-5% of,” or “within acceptable manufacturing tolerances,” or any logical combination thereof, for example.
The present disclosure is directed to a modular server system having one or more front window bays for placement of modules. The modules include a device tray that can hold a device or device carrier. Different modules can carry different devices. For example, in some implementations, the devices have different form factors. The devices can include any device for calculation and storage, such as devices selected from a 3.5 inch HDD, a 2.5 inch HDD, a SSD, a GPU, or a ruler device. Each of the one or more window bays can accept one of any of the different modules.
The server chassis 200 is dimensioned to fit into a slot of a rack. Thus, the width 201, the height 203, and the depth 205; and, the outer surfaces 222, 224, 230a, and 230b, of the server chassis 200 are configured to fit into a slot of a server rack.
Two window bays 202a, 202b, are shown in a front region 204 (shown by dotted outline). In this example, the window bay, 202a and 202b, have the same dimensions.
The window bay 202a, 202b can also be defined by bounding features. The window bay 202a is defined by the top panel 211, a bottom panel 213, the left side wall 217a, and a separator 219. The window bay 202b is defined by the top panel 211, the bottom panel 213, the right side wall 217b, and the separator 219. The bounding features include interior surfaces of the unified server chassis 200. For example, bounding features for the window bay 202b include an inner bottom surface 212, an inner top surface 214, an inner side surface 216, and a separator surface 218. In some implementations, the server chassis 200 can have 1 to 10 window bays, with each having the same dimensions.
As used herein, the “same” dimensions, with respect to the window bay 202a and 202b, refer to the configurations allowing for placement, and optionally securing of a device tray in either of window bay 202a or 202b. For example, a device tray has an outer surface and features commensurate with the inner surfaces and features defining the window bays 202a and 202b. In some implementations, the outer surfaces of the device can include a rail, and the window bay 202a, 202b include a groove as part of an inner surface. The grove engages the rail when the device is inserted in the window bay 202a, 202b. In some implementations, the outer surface of the device includes a groove, while the inner surface of the window bay 202a, 202b include a rail. The rail engages the groove when the device is inserted in the window bay 202a, 202b. The groove and rail features can aid in guiding and placement of a device tray in the window bay 202a, 202b. In some implementations, a device tray may have features, such as nubs, where the window bay 202a, 202b have commensurate features of an indentation for the nubs. Alternatively, or additionally, a device tray may have an indentation where the window bay 202a, 202b can have a nub. Other features, such as extenders, holders, or fasteners from a device tray to an inner surface defining the window bay 202a, 202b can also be used. Alternatively, features such as extenders included in the window bay 202a, 202b can extend to a device tray to hold or guide placement of the device tray in the window bay 202a, 202b. For example, features can be mounted on, attached to, or form part of, one or more of the inner bottom surface 212, the inner top surface 214, the inner side surface 216, or the separator surface 218. The features in the window bay 202a, 202b are also included in the definition of the one or more window bays each having the same dimensions as used herein.
In some implementations, a device tray can have a height about equal to the window vertical height 206, and the device tray can have a width about equal to the window horizontal width 208. In these implementations, the device tray can be about the same or less than the window depth 210. For example, the depth of the device in some implementations is as at least 10% less than, at least 20% less than, at least 30% less than, at least 40% less than, or at least 50% less than the window depth 210.
In some implementations, the modular system 300 includes a device (not shown in
The first device tray 304 includes two device slots 308a and 308b for placement of the first device carrier 302. The device slot 308a is shown unoccupied, that is, without a device carrier, such as the first device carrier 302 in the device slot 308a. A large arrow 310 illustrates slide-in placement. A first device carrier 302 slides into the first device tray 304 through the outlined aperture 312. This places the first device carrier 302 into the device slot 308a. A first device carrier 302 is shown occupying the device slot 308b.
Although referred to as “slide-in placement,” reversal of the steps can be used to remove a device or device carrier from a device tray, and to remove a device tray from a window bay. For example, the slide-in placement steps can be reversed to remove the first device carrier 302 from the device slot 308b.
The first device tray 304 can be placed into either of the window bays 202a or 202b of the unified server chassis 200. This is because the first device trays 304 have outer dimensions similar to the dimensions of the window bay 202a, 202b. For example, a device tray height 314 can be about the same as the window vertical height 206. A device tray width 316 can be about the same as the window horizontal width 208. A device tray depth 318 can be about the same as or shorter than the window depth 210 of the window bay 202a, 202b.
In some implementations, the first device trays 304 have additional features on their surfaces. For example, as illustrated by
In some implementations, the first device tray 304 is placed in the window bay 202a or 202b by slide-in placement, as shown by a large arrow 310. The first device tray 304 slides into the window openings defined by the window vertical height 206 and the window horizontal width 208. This slide-in placement places the first device tray 304 in the window bay 202a or 202b.
In other implementations, one or more of the walls defining the unified server chassis 200 can be removed. For example, at least a portion of the wall defined by the outer top surface 224 and the inner top surface 214 can be removed to allow placement of the first device tray 304 in the window bay 202a or the window bay 202b.
In some implementations, the modular system 300 includes a second device carrier for the second device 402. Any device having a matching form factor to the second device carrier can be used in the modular system 300. For example, in the implementation shown by
The second device tray 404 includes eight slots 408a-408h. For clarity, only the device slots 408a and 408h are indicated. The slots, such as device slots 408a and 408h, are configured for placement of the second device 402 in the second device tray 404. The device slot 408a is shown unoccupied by a device.
A large arrow 310 illustrates how a slide-in placement of the second device 402 into the second device tray 404, through the outlined aperture 412, can place the second device 402 into the device slot 408a. A second device 402 is shown occupying the device slot 408h.
The second device tray 404 can be placed into any one of the window bays 202a, 202b of the unified server chassis 200. This is because the second device trays 404 have outer dimensions similar to the dimensions of the window bay 202a, 202b. The second device trays 404 also have outer dimensions similar to the outer dimensions of the first device trays 304 (
An aperture 620 in the back of device tray 404′ allows for electrical connections from the second devices 402 to other components mounted in the unified server chassis 200. For example, electrical connections can be made to a mother board and a power supply through the aperture 620.
Each of second devices 402 has the same form factor. In this example, there are eight second devices 402 that fit in the corresponding device slots 408a to 408h. As used herein, a “member” is a single device in a group of devices. In some other implementations, a device tray can include more or less positions for holding devices. For example, the group of devices can have 1 to 20, or 1 to 10, or 1 to 8, or 1 to 2 members. A fastener 608 of the device 402 is shown in
In some implementations, the device tray 404′ is symmetrical from left to right and top to bottom as viewed from the front, as shown in
An aperture 820 in the back of the third device tray 804 allows for insertion of cables for electrical connections to other components installed in the unified server chassis 200.
Each of the third devices 802 has the same form factor. The devices 802 form a group of two member devices that fit in the device slots 808a and 808b. In this implementation, the device is a Graphics Processing Unit (GPU) card, but other devices may be used.
The third device tray 804 has a large open slot feature 822 formed on the top 801. In some implementations, the open slot feature 822 is provided for matching the form factor shape of the third device 802 (shown in
In the implementation illustrated by
In some implementations, one or more features of device trays as described herein can be removed, missing, or modified without altering the functioning of the device tray. For example,
The fourth device tray 1004 is configured to fit into the window bays 202a, 202b (e.g., shown in
In some implementations for assembling a unified server system, a device tray is first inserted in the window bay 202a or 202b, and then a corresponding device is placed in the device tray. For example, the first device tray 304 is placed in one of the window bays 202a or 202b, and then a device and the first device carrier 302 (
Each of the modules shown in
In some implementations the modules are aligned in rows. Thus, the top (or bottom) of the module 1206a aligns with the top (or bottom) of the module 1206b. For example, a top alignment line for R1 is a dashed line 1210 at a 1 U height. This is provided by corresponding row alignment of the window openings of the window bays 202a1, 202a2, 202b1, and 202b2. Similarly, the module 1206c and the module 1206d can be aligned in row 2 (R2). A top alignment line for row R2 is a dashed line 1212 at the 2 U height.
In some implementations, the modules are aligned in columns. For example, the side of the module 1206a is aligned with the corresponding side of the module 1206c. The side of the module 1206b is aligned to the side of the module 1206d. A dashed line 1214 shows the alignment of column C1, and a dashed line 1216 shows the alignment of column C2. The alignment of the columns is provided by a corresponding alignment of window openings of the window bays 202a1, 202a2, 202b1, and 202b2. The window bays 202a1, 202a2, 202b1, and 202b2 have similar characteristics as previously described for window bays 202a, 202b (e.g., shown in
