Abstract

The invention provides an OCP riser card and computer equipment. The riser card comprises an OCP connector, a CPLD (Complex Programmable Logic Device), a selector and a mainboard connector, wherein the CPLD is a complex programmable logic device; the OCP connector is used for connecting an OCP network card; the CPLD is used for bandwidth allocation, in-place control and power-on and power-off control of the OCP network card; the selector is used for gating the single-host host or the double-host based on the working mode configuration information stored in the CPLD; the mainboard connector isused for being connected with a mainboard device. Information interaction of each module is carried out; the functions of supporting a single host and a dual host are realized; the switching of the configuration of the single host and the dual host can be realized on the premise of not opening a case to replace a cable according to requirements, so that the design complexity of the mainboard interface is simplified, the application is more flexible and diversified, and the multiplexing of other peripherals of the PCIE interface of the mainboard end is facilitated. Meanwhile, a hot plug controlcircuit is designed in two corresponding modes.

Description

technical field [0001] The invention relates to the technical field of computer boards, in particular to an OCP adapter card and computer equipment. Background technique [0002] OCP (Open Compute Project, Open Computing Project) is an open source hardware organization initiated by Facebook in 2011 in conjunction with Intel, Rackspace, Goldman Sachs and Arista Networks. Its mission is to achieve scalable computing and provide efficient servers through open source hardware technology. , storage, and data center hardware design to reduce the environmental impact of the data center, working to innovate around networking, servers, storage, and OpenRack's open source contributions. [0003] The OCP3.0 NIC (Network Interface Card) newly announced by the current OCP project supports higher speeds, introduces more functions, and makes more optimized improvements in structure, making it easier to integrate into various types of server products. Its main features: the speed has been ...
