Embodiment 1
[0037] Embodiment one provides a blade server architecture based on redundant expansion configuration, including: at least two PCIE switch board components, at least one configuration management board and a backplane; each PCIE switch board component is connected to the backplane respectively; PCIE switch The board assembly includes: a switching board, on which a PCIE switching chipset is arranged; the PCIE switching chipset is connected to the PCIE switching chipset on the adjacent PCIE switching board assembly through a configuration management board, and the configuration management board is used to configure the PCIE switching chipset Interruption of data communication.
[0038] The PCIE switching chip set includes: at least one PCIE switching chip; when at least two PCIE switching chips are used, the PCIE switching chip and the PCIE switching chip are interconnected through the PCIE data bus to form a PCIE switching chip set; each PCIE switching chip The configuration int...
Embodiment 2
[0041] Embodiment two, such as Figure 1 to Figure 3 As shown, it includes: a first PCIE switch board assembly, a second PCIE switch board assembly, a configuration management board 4 and a backplane 2;
[0042] The first PCIE switching board assembly and the second PCIE switching board assembly are respectively connected to the backplane 2; the first PCIE switching board assembly includes: a first switching board 1 on which a first PCIE switching chipset 16 is arranged.
[0043] The second PCIE exchange board assembly includes: the second exchange board 3, the second exchange board 3 is provided with a second PCIE exchange chipset 36; the first PCIE exchange chipset 16 communicates with the second PCIE exchange chipset 36 through the configuration management board Connection, the configuration management board 4 is used to configure the on-off of data communication between the first PCIE switch chipset 16 and the second PCIE switch chipset 36 .
[0044] The first switching b...
Embodiment 3
[0048] Embodiment 3, the difference from Embodiment 1 and Embodiment 2 is that
[0049]The PCIE switching chip set includes: at least one PCIE switching chip; when at least two PCIE switching chips are used, the PCIE switching chip and the PCIE switching chip are interconnected through the PCIE data bus to form a PCIE switching chip set; each PCIE switching chip The configuration interface of the chip is connected to the configuration management board.
[0050] Wherein, as in the second embodiment, the first PCIE switch chip set 16 may use at least one PCIE switch chip. The second PCIE switch chip set 36 can use at least one PCIE switch chip.
[0051] Specifically, the PCIE switching chip adopts the PLX9797PCIE switching chip; the PLX9797PCIE switching chip and the PLX9797PCIE switching chip are interconnected through the PCIEx16 data bus to form a PCIE switching chipset; each PLX9797PCIE switching chip is connected to the configuration management board through the PCIEx1 con...
