Description

PCIe cloud platform resource pooling device

Technical Field

The utility model relates to a PCIe device field, concretely relates to PCIe cloud platform resource pooling device.

Background

The PCIe SW (switch) is a chip for expanding a PCIe interface, the PCIe interface is a mainstream interface at present, almost all devices for high-speed signals use PCIe, and the PCIe interface provided by the CPU is usually limited, so the PCIe SW is required to expand the PCIe interface, and thus, the entire system can be connected to more PCIe devices. At present, PCIe cloud service manufacturers almost adopt a single-machine single-card or single-machine multi-card binding mode, that is, one card is inserted into one server or a chip is directly configured, or a plurality of cards are inserted into one server, in this machine-card binding mode, PCIe SW is tightly coupled with a CPU, a user can only access and use the PCIe SW card through the CPU on a host side, and a PCIe device that can be used by each user is limited by the number of PCIe SW boards or chips that are bound, there is no direct data communication link between the chips, and if there is a communication requirement between the chips, data must be forwarded through a network. This cannot meet the flexible deployment requirement of services, and further cannot form an effective distributed acceleration architecture. In the above mode of machine-card binding, the PCIe SW boards are independent and separate, and the devices from upstream to downstream are limited to use and transmit, and resource pooling cannot be formed.
