Description

Technical Field

[0001] The utility model belongs to the technical field of servers, and particularly relates to a 2U server. Background Art

[0002] With the development of information technology, servers have become one of the key infrastructures to support digital development. Servers usually need to process a large amount of data and files. Generally speaking, they need to have at least several hundred GB to several TB of storage capacity to meet the data storage requirements of the servers. For common 2U servers, generally 3.5-inch or 2.5-inch SAS / SATA hard disks are installed in the front, and the number of disk bays is 8 or 12 or 24. 2.5-inch SAS / SATA hard disks are installed in the back, and the number of disk bays is 2 or 4. In addition, to improve the data reliability of the server, improve system performance, expand storage capacity, and simplify the backup and recovery process, generally, a disk array (Redundant Arrays of Independent Disks, RAID) needs to be set up for the server hard disks.

[0003] For existing 2U servers, to meet specific hard disk quantity and RAID requirements, usually a RAID card supporting x8 SAS / SATA signal bandwidth is adopted and connected to the front active backplane through a cable to support the 3.5-inch or 2.5-inch hard disks in the front. For the hard disks in the back, generally, the following solutions can be used to provide signal input for the back hard disks: Solution 1: Replace the RAID card with a model that supports x16 SAS / SATA signal bandwidth; Solution 2: Add a RAID card supporting x8 SAS / SATA signal bandwidth; Solution 3: Set up an independent SAS / SATA controller on the motherboard and provide signal input through the SAS / SATA interface on the motherboard. However, the first two solutions solve the problem of providing signal input for the back hard disks by increasing the RAID card or replacing the RAID card model. Both of the first two solutions will increase the cost of the RAID card of the whole server, thus increasing the cost of the whole server, and the second solution and the third solution cannot support the RAID operation for all 3.5-inch / 2.5-inch hard disks of the whole machine.

Obviously, the accompanying drawings in the following description are only some embodiments of the present utility model.

Additionally, the terms related to directions only represent the relative positional relationships between components, rather than absolute positional relationships.

[0022] An embodiment of the present utility model provides a 2U server. Please refer to Figure 1 、 Figure 2 , which mainly includes a server chassis, a motherboard, a front panel, a rear panel, and a first cable.

[0023] In the embodiment of the present application, the 2U server includes a server chassis. Inside the server chassis, there are a motherboard, a front panel, a rear panel, and a first cable. The motherboard is electrically connected to the front panel and the rear panel to provide the electrical energy required by the front panel and the rear panel. On one side of the rear panel, there is a first hard disk, which is fixed inside the server chassis and electrically connected to the rear panel. The front panel is provided with a SAS output module, and the rear panel is provided with a SATA input module. One end of the first cable is electrically connected to the first end of the SAS output module, and the other end is electrically connected to the first end of the SATA input module. The signals on the front panel sequentially pass through the SAS output module and the SATA input module on the rear panel and then are transmitted to the first hard disk electrically connected to the rear panel. Compared with the prior art, by adding a RAID card or replacing the model of the RAID card to support the rear hard disk to solve the problem, it will increase the cost of the RAID card of the entire server, thereby increasing the cost of the entire server. In the present application, by expanding a SAS output module on the front panel, setting a SATA input module on the rear panel, and connecting the SAS output module and the SATA input module through the first cable, the signals on the front panel sequentially pass through the SAS output module and the SATA input module on the rear panel and then are transmitted to the first hard disk electrically connected to the rear panel. It is not necessary to add or replace a RAID card to provide signal input to the first hard disk, thereby reducing the cost of the entire server. And it supports the RAID operation for all 3.5-inch / 2.5-inch hard disks of the whole machine.

[0024] Specifically, the rear panel and the first hard disk are two located on the left and right sides at the rear end of the server chassis (i.e., Figure 2 below).

[0025] In an implementable embodiment, the SAS output module includes a SAS connector, and the SATA input module includes multiple 7-pin SATA connectors. One end of the first cable has 1 interface, which is connected to the SAS connector, and the other end has the same number of interfaces as the number of 7-pin SATA connectors and is connected to multiple 7-pin SATA connectors.

[0026] It should be noted that the SAS connector is a miniaturized version of the SAS interface, mainly used in fields such as server storage and network storage devices. The SAS connector has high-speed data transmission capabilities and usually supports standards such as SAS 2.0 and SAS 3.0. The SAS connector usually includes multiple pins for transmitting power, signals, and grounding, etc. Taking the SAS connector of model SFF-8643 as an example, its pin definitions include TXA+, TXA-, RXA+, RXA-, etc., which are respectively used to transmit forward and reverse data signals. In addition, there are power supply lines (VCC), ground lines (GND), clock signal lines (CLK+ and CLK-), etc. to support the stability and accuracy of data transmission. Differential signal lines (such as A+, A-, B+, B-, etc.) need to be used in pairs to increase the transmission stability and anti-interference ability. The 7-pin SATA connector is an electronic connector used to connect to the SATA (Serial Advanced Technology Attachment) interface. The SATA interface is mainly used to connect storage devices such as hard disks and solid-state drives to the computer motherboard. The 7-pin SATA connector means that the connector has 7 pins, and these pins are responsible for transmitting data signals and control signals.

The SAS output module is connected to the SATA input module through the first cable, and the signal is transmitted to the SATA input module through the first cable. The signal on the SATA input module is then transmitted to the first hard disk.

After the signal on the motherboard received by the SAS input module is expanded by the SAS expander, it is input into the second hard drive interface module and the SAS output module. The signal received by the second hard drive interface module is transmitted to the second hard drive. The SAS output module is connected to the SATA input module through a first cable, and the signal is transmitted to the SATA input module through the first cable. The signal on the SATA input module is transmitted to the first hard drive through the first hard drive interface module.

[0031] It should be noted that the SFF-8482 connector is a specific interface connector, mainly used to connect SAS (Serial Attached SCSI) drives, including SAS hard disk drives, etc. This connector is a 29-pin connector with a plastic body, configured with 15 pins for connecting the power supply of the drive, and 7 groups of pins for transmitting SAS data signals.

[0032] Preferably, in order to facilitate the operator to visually confirm the status of the hard drive, a first indicator light and a second indicator light are fixed on both sides of the SFF-8482 connector. The first indicator light is a blue monochromatic light, used to indicate the presence of the hard drive. When the hard drive is present, this indicator light is always on. The second indicator light is a red / green dual-color light, used to indicate the working status of the hard drive. When reading and writing, the green indicator light flashes. When there is a fault, the red indicator light is always on.

[0033] In an implementable manner, a RAID control module is provided on the motherboard. The SAS input module includes a SAS connector and a SAS cable. One end of the SAS cable is electrically connected to the SAS connector, and the other end is electrically connected to the RAID control module. There are two SAS connectors and two SAS cables.

[0034] Specifically, the RAID control module includes a RAID card. The model of the RAID card is LSI 9361-8i. Among them, LSI represents the manufacturer, 9361 is the specific model, and 8i represents 8 internal ports.

[0035] In an implementable embodiment, a first power supply module and a second power supply module are provided on the main board, a third power supply module is provided on the front board, and a fourth power supply module is provided on the rear board. The first power supply module is electrically connected to the third power supply module, and the second power supply module is electrically connected to the fourth power supply module.

[0038] It should be noted that the power connector is composed of two parts: one part is a socket (or plug) fixed on the main board, front board or rear board, and the other part is a plug (or socket) at the end of the power cord.

[0039] In an implementable embodiment, a cooling fan is fixed between the front board and the rear board to enhance heat dissipation.

[0040] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
