Description
Technical Field
the invention belongs to the technical field of server monitoring management, and particularly relates to a multi-node server CMC management system and method based on I3C.
background
the bmc (baseboard Management controller) baseboard Management controller can perform operations such as firmware upgrade and checking of a machine device on the machine in a state that the machine is not started.
the CMC (sessions Management controller) chassis Management controller has similar functions as the BMC, manages and controls the whole chassis in a multi-node server such as a blade and can send commands to the BMC of each node for Management.
the CPLD (Complex Programmable Logic device) complex Programmable Logic device is a digital integrated circuit with a Logic function built by a user according to respective needs, and a server is mostly used for controlling the time sequence control of hardware startup and shutdown and the like.
GPIO (general Purpose Input output) general Purpose Input/output, abbreviated as GPIO, utilizes the high and low levels of physical pins for signal communication.
I2C (Inter-Integrated Circuit) is a name of an internal Integrated Circuit, is a serial communication bus, uses a multi-master-slave architecture, and is a simple and bidirectional two-wire synchronous serial bus.
the I3C is a two-wire serial communication bus which integrates key attributes of an I2C bus and an SPI bus, is compatible with an I2C protocol, has new characteristics of multiple master and slave soft interrupts, dynamic slave address allocation, hot plug support and the like, has the speed of up to 33Mbps, and is used for connecting a sensor to an application processor.
With the rapid development of AI, cloud computing technology and internet industry, a multi-node server is applied more and more widely in practical application, especially in large data centers, cloud computing bases and other occasions, and in the multi-node server, the Management of hardware such as nodes, fans, power supplies and the like is completed by cmc (tasks Management controller). The CMC generally obtains information such as a CPU temperature, a memory temperature, a hard disk temperature and the like from a node bmc (board Management controller) through an I2C interface, and adjusts a corresponding fan rotation speed according to a heat dissipation policy. However, the communication speed of the I2C is slow, the anti-interference capability is poor, a multi-node server needs the CMC to quickly acquire node temperature information, when the pressure of a certain node server is suddenly increased and the temperature of the CPU is quickly increased, the communication speed is slow, the time required for new temperature information from the BMC to the CMC is long, the high requirement of the heat dissipation timeliness of the whole system cannot be well met, and the heat dissipation effect is not ideal.
the CMC and the node BMC use the I2C communication mode to increase the time delay of information transmission, which is not beneficial to the quick transmission of node information and the quick response of speed regulation strategy. On the other hand, when the I2C link fails, the CMC cannot acquire information from the node BMC, which affects the normal operation of the multi-node server. For example, the variation information of the temperature cannot be acquired, so that the rotating speed of the fan is not changed, the heat dissipation strategy is disabled, and overheating or even downtime of the multi-node server system is caused.
in addition, as the machine room is enlarged and the number of nodes is increased, the traditional mode of logging in and managing the nodes one by one brings huge challenge to the management of the whole machine room, and a user hopes that all the nodes in the whole case/cabinet can be checked and managed only by logging in the CMC without logging in the nodes one by one. The low speed of I2C cannot complete the transmission of large data volume at all, and the current solution can only be realized by the mode of I2C + LAN. When a problem occurs in the LAN or the network cable fails, the CMC loses control over the node.
In a multi-node server, the CMC is responsible for managing the entire chassis/cabinet. The CMC and the node servers are positioned in the same case, one BMC exists in each node server, the CMC is connected with the BMCs of the node servers through an I2C bus, and the CMC is responsible for management work among all nodes of the whole case and also comprises power supply management, heat dissipation management and the like. The CMC obtains various information from each node for overall management, and may also configure each node information.
at present, the connection mode between the CMC and the BMCs on each node is I2C topology connection, and in addition, LAN passes through a switch topology. Because the rate of 400Kbps of the I2C bus is limited, it is difficult to transmit large data packets on the I2C bus, so the current scheme mainly transmits some simple status signals on the I2C link, and large data needs to be transmitted by means of LAN.
therefore, how to implement a method for stably and reliably acquiring information of a node CPU, a memory, a temperature, various kinds of management, and the like by the CMC becomes a problem that design and development personnel need to solve urgently.
this is a disadvantage of the prior art, and therefore, it is very necessary to provide a multi-node server CMC management system and method based on I3C to address the above-mentioned disadvantages of the prior art.
disclosure of Invention
aiming at the defect that how to realize a method for stably and reliably acquiring information such as node CPUs, memories, temperatures, various kinds of management and the like by the CMC in the prior art becomes a problem which needs to be solved urgently by design and development personnel, the invention provides a multi-node server CMC management system and a method based on I3C to solve the technical problem.
in a first aspect, the invention provides an I3C-based multi-node server CMC management system, which includes chassis management controllers CMC, server nodes and baseboard management controllers BMC, wherein each server node is provided with one baseboard management controller BMC, and each server chassis is provided with one chassis management controller CMC;
the chassis management controller CMC is connected with each baseboard management controller BMC through an I3C bus;
the chassis management controller CMC communicates with the baseboard management controller BMC on each server node via the I3C bus, and the baseboard management controller BMC on each server node manages the server node. The I3C bus has fast data transmission speed up to 33Mbps and is not limited by LAN connection.
The system further comprises a switch, and the switch is connected with the chassis management controller CMC and each baseboard management controller BMC through a local area network LAN. The chassis management controller CMC and each baseboard management controller BMC are connected by I3C, meanwhile, the local area network LAN connection is supported, the flexibility of data transmission is high, and once a certain node local area network LAN fails or a network cable is disconnected, the management of the CMC cannot be influenced.
Further, both the chassis management controller CMC and the baseboard management controller BMC use AST2600 chips. The AST2600 chip has 8I 3C channels and supports I3C bus technology, the invention is not limited to the chip, and other chips with I3C buses or PSOC can also be adopted.
in a second aspect, the present invention provides an I3C-based multi-node server CMC management method, including the following steps:
s1, a Baseboard Management Controller (BMC) on each server node manages the server node;
and S2, the case management controller CMC communicates with the baseboard management controller BMC on each server node through an I3C bus to realize management of all server nodes in the case.
further, the step S2 specifically includes the following steps:
s21, setting a Chassis Management Controller (CMC) as an I3C master control end, and setting each substrate management controller (BMC) as an I3C slave control end;
s22, when the chassis management controller CMC needs to communicate with a certain baseboard management controller BMC, the chassis management controller CMC directly sends data to the corresponding baseboard management controller BMC;
and S23, when a certain baseboard management controller BMC needs to communicate with the chassis management controller CMC, the baseboard management controller BMC sends a communication request to the chassis management controller CMC, and after the chassis management controller CMC responds to the request of the baseboard management controller BMC, the baseboard management controller BMC sends data to the chassis management controller CMC. The chassis management controller CMC is set to have I3C bus control right, and communication with the baseboard management controller BMC is initiated by the chassis management controller CMC, but the I3C bus has a "soft interrupt" (or in-band interrupt) function, so that the board management controller BMC can request communication with the chassis management controller CMC at any time without additionally connecting an IO interrupt signal line.
further, step S2 further includes the following steps:
S2A, setting data of each baseboard management controller BMC to be synchronous with data of a chassis management controller CMC; the method comprises the following specific steps:
S2A1, each baseboard management controller BMC sends the BMC system state parameters of the server node to a Chassis Management Controller (CMC);
S2A2, the chassis management controller CMC generates a BMC system state parameter mapping database of all server nodes according to the serial numbers of the server nodes;
S2A3, when the state parameter of a BMC (baseboard management controller) of a certain baseboard management controller BMC (baseboard management controller) changes, the baseboard management controller BMC sends a request for synchronously updating a BMC system state parameter mapping database to a Chassis Management Controller (CMC); after the case management controller CMC responds to the request of the baseboard management controller BMC, the case management controller CMC synchronously updates the system state parameters of the corresponding BMC in the BMC system state parameter mapping database;
S2A4, when a user configures a baseboard management controller BMC through the chassis management controller CMC, after verifying that parameters are legal, the chassis management controller CMC communicates with the corresponding baseboard management controller BMC to configure the parameters of the baseboard management controller BMC, and meanwhile updates the BMC system state parameters corresponding to the BMC system state parameter mapping database. The chassis management controller CMC uses the 2G memory 32GFlash for storing the BMC system state parameter mapping database. And the case management controller CMC maps the BMC system state parameters of all the server nodes to the case management controller CMC. Therefore, the client can obtain the data of the baseboard management controllers BMC of all the server nodes only by accessing the case management controller CMC, the case management controller CMC is prevented from reading the state parameters of the BMC system by the server nodes when the client queries, and the speed of responding to the client is increased.
further, step S2A includes the following steps:
S2A5, the chassis management controller CMC polls the BMC system state parameters of each baseboard management controller BMC at regular time;
And if the state parameter of a BMC system changes, the case management controller CMC updates the corresponding BMC system state parameter in the BMC system state parameter mapping database. The chassis management controller CMC still polls the BMC system state parameter condition of each server node at regular time to ensure parameter consistency, but the time interval of the chassis management controller CMC polling at regular time is longer and is not used for detecting at a frequency as high as that of the prior art.
Further, step S2 further includes the following steps:
S2B, setting a Case Management Controller (CMC) to manage firmware upgrading of the BMC, the BIOS and the CPLD of each server node; the method comprises the following specific steps:
S2B1, the case management controller CMC selects a server node to upgrade firmware, and obtains the model of the server node and upgradable firmware according to a BMC system state parameter mapping database;
S2B2, the case management controller CMC receives the firmware upgrade package and judges the compatibility of the firmware upgrade package according to the model of the server node;
if the version models do not accord with each other, the upgrading operation is terminated;
if the version models are consistent, entering the next step;
S2B3, the case management controller CMC judges whether the LAN bus links are communicated;
If yes, go to step S2B 4;
If not, the step S2B5 is carried out;
S2B4, the chassis management controller CMC sends the firmware upgrading packet to a baseboard management controller BMC (baseboard management controller) of the corresponding server node through the LAN bus to upgrade the firmware;
and S2B5, the case management controller CMC sends the firmware upgrading packet to the baseboard management controller BMC of the corresponding server node through the I3C bus to upgrade the firmware. In the prior art, because the I2C bus rate is too low, the chassis management controller CMC cannot perform an upgrade operation on the firmware on the server node through the internal I2C bus, and must rely on the local area network LAN to perform the upgrade operation on the server node. In the invention, because the high-speed communication of the I3C bus realizes the firmware upgrade through the internal I3C bus, even if a Local Area Network (LAN) of a certain server node fails, a client is not connected with the LAN all the time, and the Case Management Controller (CMC) can still carry out the upgrade operation on the firmware of the server node.
Further, the step S2B5 specifically includes the following steps:
S2B51, the case management controller CMC fragments the firmware upgrade package and sets that each fragment data contains a serial number and a check code;
S2B52, the case management controller CMC transmits each piece of fragment data of the firmware upgrade package at intervals through an I3C bus;
S2B53, the baseboard management controller BMC checks and unpacks each piece of fragment data for storage;
when the verification fails, the baseboard management controller BMC informs the chassis management controller CMC to resend the fragment data; returning to step S2B 52;
when the verification is successful, the baseboard management controller BMC combines the fragment data, recovers a complete firmware upgrade package, and enters the next step;
S2B54, the chassis management controller CMC informs the baseboard management controller BMC of firmware upgrading operation;
S2B55, the baseboard management controller BMC judges whether the firmware upgrade package meets the upgrade requirement of the server node;
if yes, the baseboard management controller BMC performs firmware upgrading; proceed to step S2B 56;
If not, terminating the upgrading operation; proceed to step S2B 56;
S2B56, the baseboard management controller BMC returns the firmware upgrading progress to the chassis management controller CMC. In order to prevent the phenomenon that the transmission of a dozen of megabytes of firmware upgrade packages occupies too long time of a bus and influences the timely synchronization of data of a Chassis Management Controller (CMC) and a Baseboard Management Controller (BMC), the CMC divides the firmware upgrade packages into a plurality of small pieces, each small piece is provided with a number and a check code, and then the transmission is carried out in a mode of interval transmission through an I3C bus.
further, step S2 further includes the following steps:
S2C, setting each server node of a Chassis Management Controller (CMC) to perform heat dissipation control; the method comprises the following specific steps:
S2C1, the chassis management controller CMC obtains the heat dissipation strategy, the real-time temperature and the fan control parameter of each server node from a BMC system state parameter mapping database;
S2C2, the chassis management controller CMC carries out heat dissipation adjustment according to the heat dissipation strategy, the real-time temperature and the fan control parameters of each server node;
S2C3, the case management controller CMC sends the adjusted heat dissipation strategy and the fan control parameter to the baseboard management controller BMC. In the prior art, parameters need to be acquired from the baseboard management controllers BMC of the server nodes before the chassis management controller CMC is adjusted each time, but in the invention, because a BMC parameter mapping and BMC parameter active reporting mechanism is adopted in the chassis management controller CMC, the chassis management controller CMC can perform heat dissipation adjustment by directly acquiring data from the data of the chassis management controller CMC, and the baseboard management controllers BMC of the server nodes do not need to acquire the data one by one.
the beneficial effect of the invention is that,
the I3C-based multi-node server CMC management system and method provided by the invention have the advantages that aiming at the problems existing in the current multi-node server chassis CMC management, the I3C bus is utilized to replace the original I2C bus + LAN + IO interrupted complex topology, the problems and the defects existing in the current scheme are solved, the topological complexity of a multi-node server is reduced, the stability of the management system is improved, and the expandability of nodes is improved. The CMC is in a centralized management mode, the Baseboard Management Controllers (BMC) of all the server nodes are managed in a one-stop mode, so that a client does not need to log in the BMC of the server nodes one by one for management, the workload of maintenance and management is reduced, and the user efficiency and experience are improved.
in addition, the invention has reliable design principle, simple structure and very wide application prospect.
therefore, compared with the prior art, the invention has prominent substantive features and remarkable progress, and the beneficial effects of the implementation are also obvious.
