P0973CN  扩展背板  实现主机和背板的连接和数据交互

型号：P0973CN

P0973CN 扩展背板是一种硬件组件，它提供了额外的PCIe（Peripheral Component Interconnect Express，即外设组件互连标准）插槽，用于连接和扩展更多的设备或卡。它的设计主要是为了解决主机PCIe插槽数量不足的问题，使得用户能够连接更多的设备，满足不同的应用需求。

扩展背板通常具有多槽可选的特性，比如单宽和双宽，用户可以根据自己的应用需求来选择适合的背板。同时，PCIe插槽的速度也可选择，如GEN3、GEN4，以及×8、×16等不同的规格。这使得扩展背板具有高度的灵活性和适应性，能够满足不同用户的各种需求。

在结构上，P0973CN扩展背板通过一张主机卡和一张目标卡来实现主机和背板的连接和数据交互。主机卡插入主机的PCIe插槽中，而目标卡则插入扩展背板的插槽中。这样，主机就可以通过扩展背板访问和控制连接在背板上的设备了。

此外，P0973CN扩展背板还支持适配卡与电缆的连接，单个或多个电缆可以形成更大的PCIe链路，如x4（1条电缆）、x8（2条电缆）和X16（4条电缆）等。这种设计进一步增加了扩展背板的扩展能力和灵活性。

总的来说，扩展背板是一种非常实用的硬件组件，它能够帮助用户解决PCIe插槽不足的问题，同时提供灵活的配置选项和强大的扩展能力。无论是对于需要连接大量设备的服务器，还是对于需要高性能扩展的工作站，扩展背板都是一个非常好的选择。

Model: P0973CN

The P0973CN Expansion backplane is a hardware Component that provides additional PCIe (Peripheral Component Interconnect Express) slots for connecting and expanding additional devices or cards. It is mainly designed to solve the problem of insufficient number of PCIe slots on the host, so that users can connect more devices to meet different application needs.

Expansion backplanes usually have the optional features of multiple slots, such as single width and double width, and users can choose the suitable backplane according to their application requirements. At the same time, the PCIe slot speed can also be selected, such as GEN3, GEN4, and x 8, x 16 and other different specifications. This makes the expansion backplane highly flexible and adaptable, able to meet the various needs of different users.

Structurally, the P0973CN expansion backplane realizes the connection and data interaction between the host and backplane through a host card and a target card. The host card is inserted into the PCIe slot on the host, and the target card is inserted into the slot on the expansion backplane. In this way, the host can access and control the devices connected to the backplane through the extension backplane.

In addition, the P0973CN expansion backplane also supports the connection of adapter cards and cables. A single or multiple cables can form larger PCIe links, such as x4 (1 cable), x8 (2 cables), and X16 (4 cables). This design further increases the scalability and flexibility of the expansion backplane.

Overall, the expansion backplane is a very practical hardware component that can help users solve the problem of insufficient PCIe slots, while providing flexible configuration options and powerful expansion capabilities. Whether it is for servers that need to connect a large number of devices, or for workstations that need high-performance expansion, the expansion backplane is a very good choice.
