Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily limit the invention.
As shown in fig. 2, the utility model discloses a connecting device of OCP network card mutil-host, including OCP network card and OCP keysets, be equipped with OCP network card connector and a plurality of OCP keysets end slimline connector on the OCP keysets, the OCP network card passes through golden finger and connects OCP network card connector, and a host end is connected to every OCP keysets end slimline connector.
Two OCP adapter board end slim X8 connectors are arranged on the OCP adapter board, and each OCP adapter board end slim X8 connector is connected with one slim X8 connector at the host end through a cable. An OCP3.0 network card can be connected to different hosts, namely under the CPU, at the same time. As above, an X16 OCP network card may connect the first 8-bit PCIE signal to the lower side of the CPU0 through an X8 slim line, and connect the last 8-bit PCIE signal to the lower side of the CPU1 through another X8 slim line, thereby implementing the requirement of flexible configuration.
The function of realizing the multimedia-host also needs to configure the bandwidth of the OCP, in the protocol of OCP3.0, the bandwidth is configured by three PINs of Bifurization [0:2], and for the Bifurization PIN, the protocol is required to be configurable in the STBY state. There are two ways to configure the bandwidth of the mutil-host by Bifurcation:
as shown in fig. 3, when the host-side motherboard is a BMC, the sealant connector at the OCP adapter board end is connected to the sealant connector at the motherboard end, and the sealant connector at the motherboard end is connected to a bif (bifurcation) pin of the BMC. The BIF pin and the slim line connector at the main board end are respectively connected with a first pull-down resistor. The Bifurization PIN is connected to the BMC of the mainboard and configured by the BMC, and the pull-down configuration resistor is connected to the mainboard to give an initial state to the mainboard. Because the Bifurization can only be configured under STBY, the connection to BMC can be configured with bandwidth before starting up.
As shown in fig. 4, when a PCH is located on the host board, the slim connector at the OCP adapter board end is connected to the slim connector at the host board end, and the OCP adapter board further includes a pull-up resistor, where the pull-up resistor is respectively connected to the OCP network card connector and the slim connector at the OCP adapter board end. The OCP adapter plate further comprises a second pull-down resistor, and the second pull-down resistor is respectively connected with the OCP network card connector and the slim line connector at the end of the OCP adapter plate. Because the Bifurization can only be configured under the STBY, and the PCH can only work after the start-up, the PCH can not configure the OCP bandwidth through the BIF under the STBY, therefore, only the pull-up and pull-down resistor configured on the hardware of the BIF can be connected to the OCP adapter card, and the bandwidth is configured through the forced pull-up and pull-down resistor on the hardware.
The main board end slim connector is also respectively connected with a POWER supply signal, an NCSI signal and a sideband OTHER signal.
The above description is only a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations are also considered as the protection scope of the present invention.
