In government, finance, medical treatment, energy and other industries, the demands for large core databases, virtualization integration, memory computing and high-performance computing are higher and higher, and the advantages of 8-way servers are widely applied.
The maintenance of the OCP Mezz 2.0 requires the server chassis to be uncapped for maintenance, which is not good in flexibility, and in order to solve the problem, the OCP NIC project group begins to define a new generation of network cards. OCP NIC 3.0 has adopted two kinds of dimensions of big card (LFF) and small card (SFF), insert the server chassis from the panel through the handle strip or screw, realize the chassis is not uncapped and maintained. The signal rate of the OCP card starts from PCIe Gen4, can support PCIe Gen5, and provides two PCIe interface bandwidths of x16 and x32, namely, the network card corresponding to two size specifications: SFF (Small Form Factor, Small size package, e.g., 76mmx115mm) and LFF (Large Form Factor, Large size package, e.g., 139mmx115 mm). Because the SFF specification is small, it does not take up much space in the server chassis, while the LFF specification is large, there is little server support. In the current 2-way system, due to the limitation of the structure space, it can only support SFF OCP cards in general, and due to the limitation of the number of CPUs, it can only support SFF OCP cards of 1 × X16 and 2 × X8, and due to the limitation of the system, it has no partition function, so it can only support single host OCP cards, i.e. it can support SFF OCP cards of single host with few types, only 1 × 16 and 2 × 8, no LFF OCP cards, and also no multi-host OCP cards.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a connection configuration method for 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 on 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 a pin 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 mainboard.
For a multi-path multi-node server, for example, an 8-path server, each compute node has a control chip and a management chip, such as a PCH, a BMC, and a CPLD. The mode setting of the partition needs to be informed to the three chips, each chip then being responsible for the control and management of the respective part. OCP card, Open computer Project, refers to a card used for Open source computing items.
Referring to fig. 2, fig. 2 is a schematic diagram of partition switching of a multi-server according to an embodiment of the present application. Before determining the ID signal value of the OCP card connected to the motherboard cable of the multi-node server, the partition state of the multi-node server may be determined according to the hop cap number, and then the position number of each node server may be determined according to the node position signal of the connection between the motherboard of each node server and the middle backplane. Two jump caps are arranged on a management board of the multi-path multi-node server, and the system can be set to be a single partition, a double partition and a four partition, wherein the MODE [1:0] is 11 and represents that the system is the single partition, the MODE [1:0] is 10/01 and represents that the system is the double partition, and the MODE [1:0] is 00 and represents that the system is the four partition. Each mainboard is provided with an MS [1:0] signal connected to the middle back panel, when MS [1:0] is equal to 11, the position of the computing node is represented at 0, when MS [1:0] is equal to 10, the position of the computing node is represented at 1, when MS [1:0] is equal to 01, the position of the computing node is represented at 2, and when MS [1:0] is equal to 00, the position of the computing node is represented at 3. And judging the master-slave relationship according to the partition mode and the node positions, CPLD, BMC and PCH, and carrying out related configuration. The system comprises a double-partition system or a four-partition system, wherein partitions are independent from one another, and each partition is an independent system.
In an 8-way server, the whole system is composed of 4 2-way mainboards. 2 CPUs on each mainboard can respectively output PCIE X8 signals to be connected to an MCIO connector, a high-density connector and an OCP card are directly inserted in opposite directions at the edge of the mainboard, an X8 MCIO connector is arranged near the high-density connector, and the MCIO connector is connected with the MCIO connector near the CPUs through cables. When the SFF OCP is supported, the OCP card is butted with two mainboards, and when each mainboard uses the signal of X8 of one CPU, the OCP card can support 2X 8 of 2upstream socket (dual-socket) of single host; the OCP card of 4 × 4 of 4upstream socket (quad-socket) of single host can be supported when the signal of X4 of each CPU of each motherboard. In such a multi-partition multiplexing system, if it is a single partition, two single host SFF OCP cards of 2 × x8 or 4 × x4 can be supported in the above manner, as shown in fig. 3. In the case of dual partitions, each partition may support a single host SFF OCP card of 2 × 8 or 4 × 4 as described above, or may support a dual-host SFF OCP card of 2 × 8 as shown in fig. 5, where an OCP card may be placed between two partitions and simultaneously connect node 1 of the lower partition 0 and node 0 of the upper partition 1. The Dual-host 2 x8 SFF OCP card is a multi-host OCP card, and is an 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 the two systems at the same time, and do not need to adopt any switch to realize data interaction between different partition systems, so that the number of external switches, network cards and cables can be reduced, and the total power consumption of the system can be further reduced.
In supporting LFF OCP, the OCP riser interfaces four motherboards, each using the signal of X8 of one CPU, and in single partition, can support the LFF OCP card of 4 × 8 of 4upstream socket (quad-socket) of single host, as shown in fig. 6. In the quadrant, the 4 x8 LFF OCP card of 4upstream socket (quad-socket) of quad-host can be supported, as shown in FIG. 7. For the LFF OCP card of 4 × 8 of a quad-host 4upstream socket (quad-socket), which is also a multi-host OCP card, at this time, it is an OCP card bridging two partitions (systems), and the user can interconnect with the outside through a single network card, and the external user can access the network data of the four systems at the same time, so as to reduce the number of external switches, network cards and cables, and also reduce the total power consumption of the system. In other words, if the OCP card is a small-sized encapsulated network card supporting 2 × X8 signals, and the multi-node server includes dual partitions, and the OCP card is connected to the first node server of the first partition and the second node server of the second partition, respectively, the data of the first node server and the second node server can be directly synchronized to the OCP card. In fig. 3 to 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 a PCIE signal of X8 to the first MCIO connector, a high-density connector and a second MCIO connector close to the high-density connector are provided at the edge of the motherboard, the second MCIO connector is interconnected with the first MCIO connector on the 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 overhead traces are only signals of PCIE X8, the uplink signals may be X8 signals from one CPU or X4 signals from two CPUs. For the SFF-supporting OCP card, only 2 × X8 and 4 × X4 OCPs can be supported due to the limitation of uplink signals, and when 2 × X8 sfp OCPs are supported, since each CPU has a signal of X8 pulled out to the first MCIO connector, the CPU is not limited to which CPU's signal of X8 is used, and different CPUs can be connected by a high-density connector as required. When supporting SFF OCP of 4 × X4, X4 signals of 4 CPUs on two nodes are needed, the first MCIO connector on the CPU side uses a cable of X4, and the signals of two CPUs are connected together to the second MCIO connector on the high-density connector side. Similarly, for the OCP card supporting LFF, only 4 × X8 OCP can be supported due to the limitation of uplink signals, and each CPU pulls the X8 signal to the first MCIO connector, so that it is not limited to which CPU X8 signal is used, and different CPUs can be connected by a high-density connector as required.
Further, the PCH allocates a bandwidth of a PCIE signal to the MCIO connector according to whether an X8 cable or an X4 cable is inserted. The ID signal value on the MCIO connector close to the CPU is directly connected with GND, and the ID signal value of the connector is not connected in an X8 cable, and the ID signal value to PCH/CPLD is 11; in the X4 cable, the ID signal value in the connector is connected, at which time the ID signal value to the PCH/CPLD is 00. Thus, the PCIE signal bandwidth from the CPU to the MCIO connector can be allocated by the PCH according to the ID signal value, i.e., the level value of the ID signal.
The embodiment of the application provides a method for realizing a flexibly configurable OCP (system on chip) riser card 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 into the multi-node server and used for connecting a plurality of computing nodes, and different types of OCP cards can be supported in a downlink mode according to different connection sources of uplink signals and different partition modes of a system.
