Description

PCIE Switch product architecture capable of improving production efficiency

Technical Field

The utility model relates to a server technical field, more specifically the PCIE switch product framework that says so relates to a can improve production efficiency.

Background

With the rapid development of artificial intelligence and cloud computing industries, the demand on the server is more flexible. In order to adapt to these new scenarios, the client often upgrades the traditional server center, for example, an accelerator card is added to increase the computing power, a network card is added to increase the bandwidth of the system, and the like. Currently, a PCIE Switch Box product is generally used to expand a server, that is, a traditional server is connected to the PCIE Switch Box through a PCIE bus, and resources such as an accelerator card, a network card, and a hard disk are expanded in the PCIE Switch Box.

The PCIE Switch Box expands the PCIE Bus of the server to more PCIE resources through the PCIE Switch chip, and these PCIE resources can be connected to more PCIE devices, thereby improving the performance of the original server. Meanwhile, the PCIE resources on the PCIE Switch chips can be flexibly configured through FW (firmware) in the PCIE Switch chips, that is, under the condition that hardware circuits are the same, different resources can be supported through different FWs without modifying hardware again.

The PCIE Switch Box product has the advantages of flexibility and high expansibility, so that the requirements of different customers are summarized when a system scheme is planned, a basic motherboard is designed, and when a certain customer has a requirement, the FW of the PCIE Switch IC on the motherboard is refreshed to meet the requirement of the customer (because PCIE physical resources of PCIE Switch chips are multiplexed in different FWs, that is, one FW can only correspond to one PCIE resource allocation mode, the current PCIE Switch chip cannot automatically identify different PCIE resource allocation modes yet.

For this situation, the current technical solutions generally have the following two types:

firstly, all the requirement configurations share one basic mainboard, and different FW is burned on the mainboard to correspond to different requirements. Each FW motherboard has a unique SKU code, and factory storage and production assembly are performed according to the SKU code.

And secondly, all the demand configurations share one basic mainboard, the FW with the default configuration is burnt on the mainboard, the mainboard with the default configuration is only stored during factory storage, a process is added in a production line during production, the FW with the required configuration is burnt on the mainboard again, and the FW is delivered to a customer after production and assembly are finished.

The current scheme has problems in the product storage and production processes, like the first scheme, although different configurations burn corresponding FW in advance, the FW is not required to be burned before product assembly, but the mainboards are the same, so that the problems are easily confused in the storage and production processes; in the second scheme, FW is burned again before assembly (burning time is long), so that time and labor are wasted, and although storage and production are not disordered, one procedure in the production process is increased, and the production efficiency is influenced.
