Problems solved by technology

[0002] The current blade servers are basically designed based on fixed logic chips. After the design and manufacture are completed, the hardware logic functions remain unchanged, and the backplane only has data exchange or signal channel functions.
In addition, the protocol exchange in the existing blade server cannot be changed at will, and the scalability and flexibility are limited.
Moreover, the network interface, SAN optical fiber communication, Infiniband communication, and FC interface of traditional blade servers all require corresponding interface cards on the server blade, and switches with corresponding protocols are required externally. The system is complex, costly, and unreliable.

Embodiment 1

[0030] Blade Server Gigabit / 10 Gigabit Ethernet Expansion

[0031] Such as Figure 4 with Figure 5 shown. In the figure, the high-speed transceiver channel in the PCIE interface is used to connect the SFP expansion blade. PCS is the physical coding layer of the high-speed transceiver in the FPGA, and PMA is the media additional layer of the high-speed transceiver in the FPGA.

Embodiment 2

[0033] Protocol exchange within the blade server

[0034] The programmable logic part in the FPGA can implement any digital exchange protocol to Image 6 The Ethernet protocol exchange in the figure is taken as an example. In the figure, the endpoint logic of each blade server and the Ethernet MAC realize the function of the Ethernet interface card. The Ethernet protocol switching logic implements protocol switching through FPGA logic.

Embodiment 3

[0036] Blade Server Storage Expansion

[0037] Such as Figure 7 with Figure 8 As shown, EP in the figure is the PCIE device endpoint (Endpoint), and PCS is the physical coding layer of the high-speed transceiver in the FPGA. The PMA is an additional layer of media for high-speed transceivers within the FPGA. The four high-speed channels in the PCIE interface are respectively used as the sending and receiving channels of the four SATA interfaces to realize storage expansion in the FPGA and connect to a PCIE interface device logic.

Abstract

The invention provides a programmable blade server structure which comprises a rear plate and a plurality of processor blades inserting in peripheral component interface express (PCIE) slots. The programmable blade server structure is characterized in that a transmit-receive channel of each PCIE slot is connected with a high-speed transceiver of a field programmable gata array (FPGA), wherein a channel of a primary endpoint is connected to a channel specified by a cvp configuration function. Corresponding device endpoints are respectively connected with the inner portion of the FPGA according to the corresponding PCIE slots through a plurality of PCIE endpoint IP core and are connected with a programmable logical module. The programmable logical module is connected with a PCIEIO interface. Compared with a blade server structure in the prior art, the programmable blade server structure has device expansibility and flexibility which the blade server structure in the prior art can not have.

Description

technical field [0001] The invention belongs to the field of blade servers, in particular to a programmable blade server structure. Background technique [0002] The current blade server is basically designed based on a fixed logic chip. After the design and manufacture are completed, its hardware logic function remains unchanged, and its backplane only has the function of data exchange or signal channel. In addition, the protocol exchange in the existing blade server cannot be changed arbitrarily, and the scalability and flexibility are limited. Moreover, the network interface, SAN optical fiber communication, Infiniband communication, and FC interface of traditional blade servers all require corresponding interface cards on the server blade, and external switches with corresponding protocols. The system is complex, costly, and unreliable. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a programmable blad...
