Description

Double rack

The present invention relates to a double-layer rack, in particular to a double-layer rack that is compatible with a variety of network cards and data processor configurations.

Data Processing Units (DPUs) are auxiliary computing devices used in servers and storage devices. They can generally be divided into two types: I/O interface cards and computational storage devices. I/O interface cards are mainly in the form of expansion interface cards, while computational storage devices are mainly 2.5-inch SSDs or PCIe SSD cards. These two types each have different application directions and characteristics. Among them, I/O interface cards can be further divided into types such as smart network cards, server offload processors, and computational storage controllers. Regardless of the type, they are basically a PCIe interface card with a built-in embedded computing unit and a high-speed network port, and can also be regarded as a network card with accelerated computing capabilities. Therefore, in addition to meeting basic network transmission requirements, the I/O interface card can also provide computing offload functions. On the other hand, the computing storage controller is equipped with an embedded computing unit and SSD, so it can provide computing offload services and storage functions at the same time.

In recent years, data processors have developed rapidly, and their excellent performance has made them widely used in more and more products and related applications. Therefore, today's 2U servers are usually integrated with data processors to improve computing and storage capabilities. However, since the needs of each user are different, current data processor products are mainly based on full-height half-length (FHHL) PCIe cards, and are combined with modules such as large-form-factor open computing (LFF OCP) network cards or small-form-factor open computing (SFF OCP) network cards. However, this fixed configuration method results in actual manufacturing requiring design and production for different products, and even requires the establishment of multiple production lines, and it is impossible to flexibly switch different modules according to actual needs.

The present invention provides a double-layer rack to solve the problem in the prior art that servers integrated with data processor products cannot flexibly switch between different modules according to actual needs.

The double-layer rack disclosed in one embodiment of the present invention includes a PCIe card frame, a network card frame, a PCIe adapter card and a network card connector assembly. The PCIe card frame has a PCIe assembly space for accommodating a PCIe interface card. The PCIe card frame is fixedly stacked on the network card frame. The network card frame has a network card accommodating space for selectively accommodating an OCP network card, two OCP network cards or a data processor. The PCIe adapter card is arranged in the PCIe assembly space for electrically connecting the PCIe interface card. The network card connector assembly is arranged in the network card accommodating space for electrically connecting the one OCP network card, two OCP network cards or a data processor. The double-layer rack further includes a baffle or a partition, and the baffle and the partition can be selectively installed and removed from the network card frame and located in the network card accommodating space, so that the network card accommodating space forms different accommodating space configurations to selectively accommodate the one OCP network card, two OCP network cards or a data processor.

According to the double-layer rack disclosed in the above embodiment, the baffles and partitions can be selectively installed and removed from the network card frame, so that the network card storage space can form a variety of storage space configurations to selectively accommodate one OCP network card, two OCP network cards or one data processor. In this way, through the commonality of the mold, different modules can be flexibly switched to adjust the product type in response to customer needs, and the manufacturing cost of the product can be reduced, as well as the time and cost of manual operation and maintenance.

The above description of the content of the present invention and the following description of the implementation method are used to demonstrate and explain the principle of the present invention, and provide a further explanation of the scope of the patent application of the present invention.

As shown in FIG. 4 , the two side panels 102 of the network card frame 10 may each have a plurality of convex bumps 1020 and a stop bump 1021 located in the network card receiving space S1. The convex bumps 1020 on each side panel 102 are arranged along an insertion direction D1 of the network card receiving space S1, and the convex bumps 1020 are used to carry and guide the partition 13 to move along the insertion direction D1. The stop bump 1021 is located on one side of the convex bumps 1020 to abut against the partition 13 and stop the partition 13 in the insertion direction D1.

The partition 13 is located in the network card accommodating space S1 and is detachably fixed to the network card frame 10, and the partition 13 divides the network card accommodating space S1 into two sub-spaces SB to accommodate the two LFF OCP network cards 8 respectively.

When assembling the partition 13, the partition 13 can be inserted into the network card accommodating space S1 along an insertion direction D1, and the sliding direction of the partition 13 in the network card accommodating space S1 is guided by the convex bump 1020. Then, the partition 13 can be positioned in the network card accommodating space S1 by stopping the partition 13 in the insertion direction D1 by the stopper convex block 1021. Finally, the partition 13 can be fixed to the network card frame 10 by screws F.

The two side guides 14 can be fixed to one of the side plates 102 by screws F and extend along the insertion direction D1, and the two side guides 14 are respectively located in the two sub-spaces SB of the network card accommodating space S1. The two bottom guides 15 can be fixed to the bottom plate 100 and the partition plate 13 by screws F and extend along the insertion direction D1, and the two bottom guides 15 are respectively located in the two sub-spaces SB of the network card accommodating space S1. The side guides 14 and the bottom guides 15 located in the same sub-space SB are used to jointly carry and guide one of the LFF OCP network cards 8 to slide along the insertion direction D1.

In this embodiment, the two network card connectors 110 of the network card connector assembly 11 can be fixed to the bottom plate 100 and the partition plate 13 respectively through screws F, and the two network card connectors 110 are respectively located in the two sub-spaces SB of the network card accommodating space S1, and are respectively used to electrically connect the two LFF OCP network cards 8.

Please refer to Figures 5 and 6. Figure 5 is a three-dimensional schematic diagram of a double-layer rack accommodating two SFF OCP network cards according to the second embodiment of the present invention, and Figure 6 is an exploded schematic diagram of the double-layer rack and SFF OCP network card of Figure 5.

In the second embodiment, the double-layer rack 1 is another storage space configuration for accommodating two SFF OCP network cards 7.

In addition, the side guide 14 and the bottom guide 15 for guiding the LFF OCP network card 8 and the network card connector 110 for electrically connecting to the LFF OCP network card 8 are also adaptively adjusted to corresponding quantities corresponding to this storage space configuration.

The baffle 17 can be fixed to the network card frame 10 through screws F and cover a portion of the opening O1 of the network card accommodating space S1, and the baffle 17 is used to stack with the LFF OCP network card 8 in the height direction D2 of the network card accommodating space S1. In this way, the baffle 17 can provide a dustproof effect.

That is, the double-layer rack 1 can form a storage space configuration for accommodating a data processor 6 by selectively removing the partition 13 and the baffle 17 from the network card frame 10 (i.e., not installing the partition 13 and the baffle 17). In addition, the side guide 14 and the bottom guide 15 for guiding the data processor 6 and the network card connector 110 for electrically connecting to the data processor 6 are also adaptively adjusted to the corresponding number corresponding to this storage space configuration.
