In some implementations of the present embodiment, the external power source provides +220v ac mains to the power blades, which convert it to +48v for supply to the heat sink 140, to +12v for supply to other functional blades 130 (such as compute blades, switch blades, and storage blades), and to +3.3v for supply to the BMC units in each functional blade 130.

As one example, chassis 110 is configured as a standard 19 inch chassis, forced air cooling heat dissipation, 8U height, with the external dimensions: 482.6mm wide (+ -2 mm, inclusive of the front panel), 354.8mm high (+ -2 mm) and less than or equal to 400mm deep (+ -2 mm). Further, each functional blade 130 in the blade server 100 conforms to the VPX specification and has a standard 6U structure, and the back-plane 120 also adopts a 14-slot VPX standard back-plane correspondingly, that is, the blade slots 121 on the back-plane 120 include fourteen slots.

As one example, fig. 4 shows an interconnection topology diagram between all blade slots 121 on the backplane 120, and the interconnection design inside the system (i.e. the blade server 100) refers to the design concept of VPX/OpenVPX, i.e. the system logic architecture is divided into a basic Plane (Utility Plane), a monitoring Plane (Management Plane), a Control Plane (Control Plane), a Data Plane (Data Plane), and an extension Plane (extension Plane), where planes actually refer to physical and logical channels of interconnection between devices; in fig. 4, a denotes an extension plane bus, B denotes a data plane bus, C denotes a control plane bus, D denotes a monitor plane bus, E denotes a +48V voltage supplied to the heat sink 140, F denotes a +3.3v voltage supplied to the BMC unit in each functional blade 130, and G denotes a +12v voltage supplied to other functional blades 130 (such as a compute blade, a switch blade, and a memory blade). Preferably, for a data plane bus, four 40G high speed serial buses are followed; for the control plane bus, two paths of 1G electric ports and one path of hundred-megameter management network ports are arranged behind the control plane bus; for the monitor plane bus, an IPMI (Intelligent Platform Management Interface ) bus is output.

In some implementations of the present embodiment, for the base plane, it provides the most basic services for the system, which may include but is not limited to, contents such as system power supply, system reference clock, system reset, system test signal, etc., while the system power supply may be configured as two VPX-based power blades, and may output 1900W of power to the outside (12V output to the compute blade, switch blade, and other functional blades 130 such as storage blade is greater than or equal to 1600W, 48V output to the heat sink 140 is greater than or equal to 260W, and 3.3V output to the BMC unit in each functional blade 130 is greater than or equal to 90W), thereby ensuring that the system can perform full load operation. In the control signal design of the base plane, the system reset signal is valid at low level, the system management interface signal adopts a dual redundancy interface, and of course, the slot identification signal of each blade slot 121 and the like are also included, and will not be described in detail herein. In the ground design of the base plane, all the chassis grounds of the functional blades 130 are kept isolated from the signal ground, the high-speed signal connector housing is interconnected with the signal ground through a high-voltage (more than or equal to 1200V) blocking capacitor, the signal ground of the back plate 120 and the chassis ground are reserved with short contacts (capable of carrying 20A current), and the impedance between the chassis ground and the ground (earth) is less than 100 milliohms.

For the monitoring plane, it is used for organizing and managing hardware resources based on IPMI standard, and mainly includes a chassis management controller (ChMC) and a Baseboard Management Controller (BMC), where the chassis management controller is borne by a BMC unit in the switch blade, and is mainly used for: power up and power down management of each functional blade 130; monitoring the temperature inside the cabinet 110; control of the heat sink 140; detecting the working information of each functional blade 130; responding to the remote control command, processing error alarm information and recording the error alarm information in a system log; providing a unified management interface of the chassis 110 and each functional blade 130 for an external network; the operation information of the function blade 130 includes operation state information and health state information, such as type information and on-line information of the function blade 130, and the heat sink 140 is controlled by PWM/TACH generated by the chassis management controller. Further, the BMC unit of the functional blade 130 is mainly used for: performing power-on and power-off management on each functional unit; temperature, voltage, and blade information detection of the functional blade 130 (blade information such as type information, slot identification information of the inserted blade slot 121, etc.); responding to the IPMI control command, processing error alarm information and recording the error alarm information in a system log.

For the control plane, the control plane needs to use a low latency, medium bandwidth, packet based communication mode according to the OpenVPX standard requirements. OpenVPX ensures the bandwidth of each path by distinguishing Control Traffic (Control Traffic) from Data Traffic (Data Traffic) and collisions of one path do not affect the other. The control plane of the system comprises two parts: the gigabit Ethernet is used for bearing application management and control data and adopts a double-star topology architecture; GPIO signals (LVTTL levels) are used to carry interrupt signals and clock synchronization signals. Specifically, each functional blade 130 outputs 4-way Serdes signals and 1-way MDI signals, wherein 2-way Serdes signals are respectively interconnected with 2 switch blades through the backplane 120, and the other 2-way Serdes signals are interconnected with external devices through the connector 122 and the communication interface 112, wherein 1-way Serdes signals are optional, and 1-way MDI signals are output to the front panel of the chassis 110. The 4-way single-end GPIO signals input from the outside of the system are input to the connector 122 on the second side of the back plate 120 through the communication interface 112 of the back plate of the chassis 110, and are converted into 4-way GPIOs (3.3V LVTTL) through the connector 122, and are input to the respective functional blades 130 in parallel, in which case each functional blade 130 includes a CPLD/FPGA for processing the signals, and relevant information is transferred to an application running on the CPU (the application should be able to respond to the signals quickly and make corresponding processing).

For the data plane, according to OpenVPX standard requirements, the data plane is responsible for constructing a set of high-bandwidth and low-delay data paths between boards and on a bottom board, and is used for carrying service data (such as echo data, intermediate processing process data and the like) of information processing. Because the system needs to be compatible with the functional blade 130 formed by different processors such as a CPU, an FPGA and the like, wherein the CPU can conveniently output 40GbE, and 40GbE ethernet is an important development trend in the future, the data plane of the blade server 100 designs a 40GbE ethernet interconnection network. Specifically, the CPU-based functional blade 130 outputs a 40GbE interface, where the 40GbE ethernet is interconnected with a 40G ethernet switch blade, and the system has two interface modules to implement internal and external data interface conversion: firstly, a computing interface module converts an external optical fiber interface into a PCIe interface through an FPGA (field programmable gate array), external data is input into a system internal functional blade 130, and the functional blade 130 transmits the data to other functional blades 130 through an internal switching network for processing; second, the switch interface module forwards the data to the functional blades 130 inside the system by converting the external fiber interface to a 40GbE ethernet interface and then through the switch blade.

For the extension plane, it is used to implement interconnection of each functional blade 130 (if each functional blade 130 supports outputting a set of pcie3.0 x16, pcie3.0 x8 serial interconnection architecture is adopted between each functional blade 130); it should be noted that, the extension plane is the same as the data plane, and the extension plane also needs to support its communication using low-latency, high-bandwidth channels.

For such a domestic blade server 100, its main functions are system data processing, resource scheduling, and data storage and playback; in the system, star-shaped interconnection modes based on 40GbE and gigabit network are adopted among the functional blades 130, and the functional blades 130 are equal in status, consistent in communication mode and basically consistent in communication delay, so that the expansion and contraction in the system are easy to realize; for higher-performance application systems, multistage expansion can be realized based on the interconnection of the exchange blades among the chassis 110, and transverse expansion of the chassis level can be realized; the user can construct a processing flow according to the task requirements; the system can adopt an I2C bus to realize system monitoring, can meet the expansion requirement in the case 110, and in order to support the long-distance transmission after the expansion of the case 110, the monitoring data on the I2C can be converted into Ethernet data packets on the switch blade, and then the long-distance transmission is realized through the Ethernet interconnection among the cases 110.
