Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart of a connection configuration method between a multi-node server and an OCP card according to an embodiment of the present application, where the method includes:
s101: when the OCP card is connected to the multi-node server, determining an ID signal value of a mainboard cable of the multi-node server, which is accessed by the OCP card;
s102: if the ID signal value is a first signal value, determining that the OCP card adopts an X8 cable, and controlling a pin of a first MCIO connector, close to a CPU end, in a node server corresponding to the OCP card to be grounded;
s103: and if the ID signal value is a second signal value, determining that the OCP card adopts an X4 cable, and controlling pins of a first MCIO connector, close to a CPU end, in a node server corresponding to the OCP card to be connected with a second MCIO connector at the edge of a node service main board.
For a multi-path multi-node server, such as an 8-path server, each computing node has a control chip, such as PCH, BMC, CPLD, and a management chip. The mode setting of the partition needs to be informed to the three chips, and then each chip is responsible for the control and management of the respective part. OCP card Open Compute Project refers to a card for open source computing items.
Referring to fig. 2, fig. 2 is a schematic diagram of partition switching of a multi-path server according to an embodiment of the present application. Before determining the ID signal value of the cable of the main board of the OCP card connected to the multi-node server, the partition state of the multi-node service can be determined according to the jump cap number, and then the position number of each node server can be determined according to the node position signal of the main board of each node server connected with the middle backboard. Two jump caps are arranged on a management board of the multi-path multi-node server, the system can be set to be a single partition, a double partition and a four partition, MODE [1:0] =11, the representative system is a single partition, MODE [1:0] =10/01, the representative system is a double partition, MODE [1:0] =00, and the representative system is a four partition. Each motherboard has MS [1:0] signal connected to the middle backplane, where MS [1:0] =11 represents the position of the computing node at 0, MS [1:0] =10 represents the position of the computing node at 1, MS [1:0] =01 represents the position of the computing node at 2, and MS [1:0] =00 represents the position of the computing node at 3. And judging a master-slave relationship according to the partition mode and the node position, and carrying out relevant configuration by the CPLD, the BMC and the PCH. The system is a double-partition or four-partition system, the partitions are independent from each other, and each partition is an independent system.
In the 8-path server, the whole system consists of 4 2-path mainboards. The 2 CPUs on each main board can respectively output PCIE X8 signals to be connected to one MCIO connector, a high-density connector and an OCP card are directly inserted at the position of the board edge, and an X8 MCIO connector is also arranged near the high-density connector and is interconnected with the MCIO connector near the CPU through a cable. When supporting SFF OCP, the OCP card is butted with two mainboards, and when each mainboard uses X8 signals of one CPU, the OCP card can support 2X 8 OCP cards of 2upstream sockets of single host; when the signal of X4 of each CPU of each motherboard, 4X 4 OCP cards of 4upstream socket (quad-socket) of single host can be supported. In such a multi-partition multiplexing system, if it is a single partition, two SFF OCP cards of 2 x8 or 4 x4 single host can be supported as described above, as shown in fig. 3. In the case of dual partitions, each partition may support a single-class 2 x8 or 4 x4 SFF OCP card, as shown in fig. 4, or may place an OCP card between two partitions, while connecting node 1 of the lower partition 0 and node 0 of the upper partition 1, and may support a single-class 2 x8 SFF OCP card, as shown in fig. 5. The Dual-host 2 x8 SFF OCP card is a multi-host OCP card, at this time, the Dual-host OCP card is one OCP card bridging two partitions (systems), users can be interconnected with the outside through a single network card, external users can access network data of the two systems at the same time, data interaction among different partition systems is realized without adopting any switch, the number of external switches, network cards and cables can be reduced, and the total power consumption of the systems is further reduced.
In supporting LFF OCP, the OCP riser interfaces with four boards, each board using X8 signals from one of the CPUs, and in single partition, can support LFF OCP cards of 4X 8 of 4upstream sockets (quad-sockets) of single host, as shown in fig. 6. In the case of the quartering, a 4 x8 LFF OCP card of the 4upstream socket (quad-socket) of quad-host can be supported as shown in fig. 7. For the 4 x8 LFF OCP card of the 4upstream socket (quad-socket) of quad-host, which is also a multi-host OCP card, at this time, one OCP card bridging two partitions (systems), users can be interconnected with the outside through a single network card, and external users can access network data of four systems at the same time, so that the number of external switches, network cards and cables is reduced, and the total power consumption of the systems is also reduced. In other words, if the OCP card is a small-sized package network card supporting 2×8 signals, and the multi-node server includes dual partitions, and the OCP card is respectively connected to the first node server of the first partition and the second node server of the second partition, the data of the first node server and the second node server can be directly synchronized to the OCP card. In fig. 3 to fig. 7, two ends of the PCIE cable are respectively connected to the first MCIO connector and the second MCIO connector, where the first MCIO connector is close to the CPU.
It should be noted that, each CPU on the motherboard outputs an X8 PCIE signal to the first MCIO connector, the edge of the motherboard has a high-density connector and a second MCIO connector close to the high-density connector, and the second MCIO connector is interconnected with the first MCIO connector on one side of the CPU end through a cable, and the high-density connector is in butt joint with the OCP card.
Since the high-density upper design trace is only a PCIE X8 signal, the upstream signal may be from an X8 signal of one CPU or an X4 signal of two CPUs. For an OCP card supporting SFF, only 2×x8 and 4×x4 OCPs can be supported due to the limitation of the uplink signal, and when an SFF OCP of 2×x8 is supported, since each CPU has a signal of pulling out X8 onto the first MCIO connector, the X8 signal of which CPU is used is not limited, and the high-density connector can connect different CPUs as required. When supporting SFF OCP of 4X 4, X4 signals from 4 CPUs on two nodes are needed, the first MCIO connector at the CPU end uses an X4 cable, and the signals from two CPUs are connected together to the second MCIO connector at the high-density connector end. Similarly, when the OCP card supporting the LFF is used, only 4X 8 OCPs can be supported due to the limitation of the uplink signal, and since each CPU has a signal for pulling out X8 to the first MCIO connector, the specific use of which CPU X8 signal is not limited, and different CPUs can be connected to the high-density connector according to the requirement.
Furthermore, PCH allocates bandwidth of PCIE signals to MCIO connectors depending on whether X8 or X4 cable is plugged. The ID signal value on the MCIO connector close to the CPU is directly connected with GND, and in the X8 cable, the ID signal value of the connector is not connected, and at the moment, the ID signal value to the PCH/CPLD is 11; in the X4 cable, the ID signal value in the connector is connected, and the ID signal value to PCH/CPLD is 00 at this time. Thus, the PCH may allocate PCIE signal bandwidth from the CPU to the MCIO connector based on the ID signal value, i.e., the level value of the ID signal.
The embodiment of the application provides a flexible configuration OCP riser card realization method applied to a multi-node multi-partition server, wherein one or two OCP riser cards (SFF OCP riser or LFF OCP riser) are vertically inserted in the multi-node server and are used for connecting a plurality of computing nodes, and different types of OCP cards can be supported in the downlink according to different sources of connecting uplink signals and different partition modes of a system.
