Description
Technical Field
The invention relates to the field of BMC firmware storage, in particular to a BMC firmware dynamic storage method and system based on an ad hoc network.
Background
The BMC is a core component for deploying/diagnosing/managing a server, is responsible for managing an interface between system management software and platform management hardware, and provides functions of autonomous monitoring, event recording, recovery control and the like. The BMC in the narrow sense will be understood to be a separate management chip on the server motherboard in general; but in a broad sense, BMC is an SOC system, which is divided into two layers, BMC chip and BMC firmware.
The current computer architecture is composed of von neumann architecture, and is divided into input device, memory, arithmetic unit, controller and output device. This is of course also the node that the server business runs, but BMC does not belong to the above business node's constituent part, so it does not depend on other hardware on the system, such as CPU, memory, hard disk, etc.; nor does it rely on other software on the system, such as BIOS, OS, CPLD, etc., see fig. 1, which is a schematic diagram of the existing server management network and service network separation architecture, that is: the BMC is a set of special management small systems which are completely independent of the computing nodes of the server, and is based on a von Neumann architecture, but has larger authority than a host server, so that the separation of service nodes and management nodes is effectively ensured, the service nodes are not interfered by the management nodes, and the management nodes can manage and monitor the service nodes in real time.
A traditional data center server is configured with a BMC management chip embedded in a server main board end. But with the rise of the concept of cpu+gpu+dpu in recent years, the CPU is used for general-purpose computing, the GPU is used for accelerating computing, and the mode of DPU for data processing is defined as a trend of future cloud computing architecture. Because the high-value parts of the GPU and the DPU bear the important workload of the platform, the embedding of the BMC management chip is also expanded from the mainboard level to the part level, and even a single server platform can consume a plurality of BMC management chips, the demand of the BMC management chip of the global server market is increased or reduced.
For BMC firmware, which is also an integral part of the BMC system, the BMC firmware is typically downloaded through a remote firmware management platform and then fixedly stored in a corresponding storage device. Although the storage device storing the BMC firmware can only be modified and adjusted by the administrator authority, since the number of terminals managed by the server is generally large, when normal communication is performed between the server management terminals or multiple servers, more intrusion opportunities are provided for illegal intruders, so that the storage mode of the current fixed storage BMC firmware is easily subjected to malicious intrusion of illegal "hackers", and therefore, a safer storage scheme of the BMC firmware is needed to be provided.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Example 1
The embodiment provides a method for dynamically storing BMC firmware based on an ad hoc network, a flow chart of which is shown in fig. 2, wherein the method comprises the following steps:
s1, connecting two opposite vertexes on the bottom surface of a server, and taking the vertexes as diameters to form a circumcircle of the bottom surface of the server; since the general server has a regular hexahedral structure, such as a cuboid, the bottom surface of the server can be regarded as a rectangle, and serves as an external circle of the bottom surface of the server, so that when each chip configured in the server is projected to the bottom surface of the server, the projections can be located in the external circle, and in order to increase the security of the BMC firmware ad hoc network dynamic storage link, a buffer storage area 101 needs to be selected from the external circle, and then a buffer storage node is selected;
s2, establishing a two-dimensional coordinate system based on the circumscribed circle, wherein an x-axis of the two-dimensional coordinate system is circumscribed on the circumscribed circle of the bottom surface of the server and is parallel to the wide side of the bottom surface of the server, and a y-axis of the two-dimensional coordinate system is circumscribed on the circumscribed circle of the bottom surface of the server and is parallel to the long side of the bottom surface of the server; referring to fig. 3, a schematic diagram of a coordinate system established in the present embodiment is shown;
s3, projecting the substrate of the BMC firmware storage chip in the server and the substrates of all other chips with storage functions to the two-dimensional coordinate system, and taking the BMC firmware storage chip as an initial storage node; since a large number of chips with memory function are configured in the server, when each chip is projected, there may be a situation that the positions of the plurality of chip substrates are the same, so that the areas projected into the two-dimensional coordinate system overlap, so that the number of times of selecting the center coordinates can be reduced in the selection procedure of the intermediate memory node, and the minimum x value x is selected in the embodiment min Center coordinates, maximum x value x max Center coordinates, minimum y value y min Center coordinates and maximum y value y of (c) max Therefore, the situation that the center coordinates are coincident also occurs, when the coordinates are coincident, one of the coincident coordinates can be selected, and the construction process of the BMC firmware ad hoc network dynamic storage link in the implementation is not influenced;
s4, acquiring center point coordinates of the substrate projected to all other chips with the storage function in the two-dimensional coordinate system, and selecting an intermediate storage node based on the center point coordinates;
s5, constructing a BMC firmware ad hoc network dynamic storage link based on the intermediate storage node;
and S6, after the BMC firmware is downloaded from the remote firmware management platform to the BMC firmware storage chip, dynamically storing the BMC firmware according to the built BMC firmware ad hoc network dynamic storage link.
In this embodiment, a server corresponds to one BMC management chip, and one BMC firmware is correspondingly configured, which is, of course, also applicable to the method for dynamically storing BMC firmware based on the ad hoc network provided in this embodiment if one server configures a plurality of BMC management chips.
In this embodiment, in order to enable the BMC firmware to dynamically store, a dynamic storage link needs to be built, and when the dynamic storage link is built, an intermediate storage node needs to be necessarily selected, so in this embodiment, the selecting an intermediate storage node based on the center point coordinate specifically refers to:
will be equal to the minimum x value x min A chip with a storage function corresponding to the center point coordinates of the first intermediate storage node;
will be equal to the maximum x value x max A chip with a storage function corresponding to the center point coordinates of the first intermediate storage node;
will be equal to the minimum y value y min A chip with a storage function corresponding to the center point coordinates of the first intermediate storage node;
will be equal to the maximum y value y max The chip with the storage function corresponding to the center point coordinates of the (c) is used as a fourth intermediate storage node.
For a BMC firmware ad hoc network dynamic storage link, the two cases can be divided, wherein the storage link only comprises an initial storage node and an intermediate storage node, and the second case is that the storage link comprises not only the initial storage node and the intermediate storage node but also a buffer storage node.
For the first storage link case, in this embodiment, the building of the BMC firmware ad hoc network dynamic storage link based on the intermediate storage node specifically refers to:
and the initial storage node, the first intermediate storage node, the second intermediate storage node, the third intermediate storage node, the fourth intermediate storage node and the initial storage node are sequentially connected to construct a BMC firmware ad hoc network dynamic storage link.
Specifically, in the case of the first storage link, the dynamic storage BMC firmware of the built BMC firmware ad hoc dynamic storage link specifically refers to:
after a BMC firmware ad hoc network dynamic storage link is constructed, and the BMC firmware is downloaded from a remote firmware management platform to a BMC firmware storage chip, setting a first storage time of the BMC firmware in an initial storage node and a second storage time of each intermediate storage node;
when the BMC firmware is transmitted in the BMC firmware ad hoc network dynamic storage link, if the storage time of the BMC firmware in the initial storage node reaches the first storage, transmitting the BMC firmware to the first intermediate storage node;
and if the storage time of the BMC firmware in the intermediate storage node reaches the second storage time, transmitting the BMC firmware to the next intermediate storage node, wherein if the storage time of the BMC firmware in the fourth intermediate storage node reaches the second storage time, transmitting the BMC firmware to the initial storage node.
It should be noted that the first storage time and the second storage time may be set freely according to the actual application scenario of the server, but when the first storage time and the second storage time are set, in order to ensure the stability of the storage link, both the first storage time and the second storage time are set to be unchangeable.
In the second storage link case, since the intermediate storage nodes are all related to the positions of the chips with the storage function arranged in the server, even if the positions of the chips projected to the two-dimensional coordinate system are changed, the selection of the intermediate storage nodes is also selected based on the x value and the y value in the coordinates, so that the selection of the intermediate storage nodes is relatively fixed, if an illegal hacker invades the first storage link, the BMC firmware still has a potential safety hazard, so that in the second storage link case, in order to improve the safety of the BMC firmware storage, the buffer storage nodes can be randomly selected in the buffer storage area 101, and when the BMC firmware is dynamically stored again after the link is cycled once, the safety of the storage link can be greatly increased due to the randomness of the selection of the buffer storage nodes, and meanwhile, the transmission of a time closing related control instruction can be provided for an operator while the illegal hacker invades, so that the BMC management chip can be prevented from issuing an error instruction.
Therefore, after the selecting the intermediate storage node based on the center point coordinates and before constructing the BMC firmware ad hoc network dynamic storage link based on the intermediate storage node, the method may further include:
forming four buffer areas outside the bottom surface area of the server and inside the circumscribing circle;
selecting a minimum x value x min A buffer area with the nearest central point coordinate is used as a first buffer area;
selecting a distance maximum x value x max The buffer area with the nearest central point coordinate is used as a second buffer storage area;
selecting a distance minimum y value y min The buffer area with the nearest central point coordinate is used as a third buffer storage area;
selecting a distance maximum y value y max The buffer area closest to the center point coordinates of (c) is taken as a fourth buffer storage area.
After the four buffer areas are selected, randomly selecting one buffer storage node from each buffer storage area, and constructing a BMC firmware ad hoc network dynamic storage link based on the intermediate storage node and the buffer storage node.
Therefore, the building of the BMC firmware ad hoc network dynamic storage link based on the intermediate storage node and the buffer storage node specifically refers to:
the buffer storage nodes selected randomly in each buffer area are respectively marked as a first buffer storage node, a second buffer storage node, a third buffer storage node and a fourth buffer storage node;
the initial storage node, the first intermediate storage node, the first buffer storage node, the second intermediate storage node, the second buffer storage node, the third intermediate storage node, the third buffer storage node, the fourth intermediate storage node, the fourth buffer storage node and the initial storage node are sequentially connected to construct the BMC firmware ad hoc network dynamic storage link.
It should be noted that, for the second storage link situation, the dynamic storage BMC firmware of the built BMC firmware ad hoc network dynamic storage link specifically refers to:
after a BMC firmware ad hoc network dynamic storage link is constructed, and the BMC firmware is downloaded from a remote firmware management platform to a BMC firmware storage chip, setting a first storage time of the BMC firmware in an initial storage node, a second storage time of each intermediate storage node and a third storage time of each buffer storage node;
when the BMC firmware is transmitted in the BMC firmware ad hoc network dynamic storage link, if the storage time of the BMC firmware in the initial storage node reaches the first storage, transmitting the BMC firmware to the first intermediate storage node;
if the storage time of the BMC firmware in the first intermediate storage node reaches the second storage time, transmitting the BMC firmware to the first buffer storage node;
after the storage time of the first buffer storage node reaches the third storage time, the BMC firmware is transmitted to the second intermediate storage node;
after the storage time of the BMC firmware reaches the second storage time, the BMC firmware is transmitted to a second buffer storage node;
after the storage time of the second buffer storage node reaches the third storage time, the BMC firmware is transmitted to a third intermediate storage node;
after the storage time of the BMC firmware reaches the second storage time, the BMC firmware is transmitted to a third buffer storage node;
after the storage time of the third buffer storage node reaches the third storage time, the BMC firmware is transmitted to a fourth intermediate storage node;
after the storage time of the BMC firmware reaches the second storage time, the BMC firmware is transmitted to a fourth buffer storage node;
and after the storage time of the fourth buffer storage node reaches the third storage time, the BMC firmware is transmitted to the initial storage node.
In actual operation, since the buffer storage areas 101 do not belong to the configuration of the server itself and are not within the rectangular range of the bottom surface of the server, a corresponding storage device may be configured for each buffer storage area 101 to store BMC firmware, however, in this embodiment, the storage device configured in each buffer area is only used for data reading and writing when the BMC is transmitted to, and does not store any other data, and only when the buffer storage area is in communication with the initial storage node and the intermediate storage node, the buffer storage node may be a USB storage device, and the USB storage device only communicates with the intermediate storage node and the initial storage node and performs data reading and writing.
In addition, when the BMC firmware dynamically stores in the second storage link, the selection of the buffer storage node is random, and if the buffer storage node changes the position every time, it is obvious that more operation and maintenance costs are wasted.
Example 2
