technical field

The present invention relates to the technical field of high-density computing servers, and specifically relates to a cloud server architecture capable of realizing interconnection and management among nodes. the

Background technique

With the development of cloud computing technology, people's demand for high-density computing servers is becoming more and more intense. During this period, a multi-node, high-density, low-power cloud computing server emerged as a high-density server architecture , which is characterized by:

1) The power consumption of a single node is small, the power consumption of the whole board is less than 50W, and the power consumption of the CPU is less than 20W.

2) The computing density is high, and there are often 8 to 10 nodes in a 2U standard chassis. Allow many users to access at the same time. The CPU has weak computing power, but has rich interfaces, which is suitable for multi-node intensive applications. the

3) Single node design is simple and low cost. the

Based on the above characteristics, cloud servers are increasingly welcomed by many cloud server cluster architects and become a popular model for cloud service cluster applications in the future. However, in the current cloud server models of major manufacturers, multiple nodes in the rack Generally, they exist independently and have no interconnection relationship with each other. Moreover, although they take power from the same group of power supplies, they cannot realize unified power consumption management and fan management functions, which has become the main defect of this server architecture. the

Contents of the invention

The present invention provides a cloud server architecture that can realize interconnection and management among nodes, and aims to increase the network interconnection function between nodes of the cloud server, and at the same time use the interconnection network to realize the operation log and power consumption management functions of each node. the

The technical solution adopted by the present invention to solve its technical problems is:

There are interconnection paths between nodes, and in-band and out-of-band management can be realized, which mainly includes two aspects:

1) Multiple nodes in the same chassis can be interconnected through Gigabit Ethernet switching modules;

2) Between multiple nodes of the cloud server, the interconnected network can be connected and in-band and out-of-band management between nodes can be realized.

In the cloud server architecture, one of the nodes is the main node, and the management terminal software is installed on the node. the

In the above-mentioned cloud server architecture, the main chassis can obtain the operation log information, power consumption and temperature information of other nodes through the Gigabit Internet, so as to realize the operation and power consumption management of other nodes. the

In the above cloud server architecture, a Gigabit network chip with NC-SI interface can be selected in a single node, and connected to the RMII of the monitoring and management chip of each node. the

The invention has multiple nodes, high density, and low power consumption, realizes interconnection and management among nodes, increases the network interconnection function among nodes of the cloud server, and realizes unified power consumption management and fan management functions. the

Detailed ways

As shown in Figure 1, an 8-node cloud server in a single rack is used as an example for illustration. Each cloud server rack will have a unified power supply backplane to supply power to each node. In this invention, we place a 16-port Gigabit Ethernet switch chip on the power supply backplane, of which 8 The other 8 ports are connected to the external ports of the network for external output, realizing the full wire-speed external exchange of eight inputs and eight outputs, and also realizing the interconnection between 8 nodes. the

Select a master node among the 8 nodes. The selection of the master node is flexible. It mainly depends on which node the management terminal software is installed on. This node is the master node. The master node can be connected to the power supply and the fan controller on the backplane through the PMbus and the SMbus respectively, so as to realize the power consumption and fan heat dissipation management of the chassis. the

The Gigabit Internet through which the main chassis passes can obtain the operation log information, power consumption and temperature information of other nodes to realize the operation and power consumption management of other nodes. Therefore, the master node, which is the management center of each node, plays a vital role in the operation of the entire server rack. Therefore, there is usually a hot standby master node among other nodes, which can take over after the master node fails. All the work of the master node, get all the running logs and power consumption information, so that the operation of other nodes will not be affected, and report the fault information to the upper network management. the

As shown in Figure 2, a Gigabit network chip with NC-SI interface can be selected in a single node, and connected to the RMII of the monitoring management chip (BMC) of each node, so that the normal network interconnection and external network between each node When interconnected, the chip is an in-band network chip for normal network transmission applications. At the same time, the BMC can also be connected to the BMC card of other nodes through the NCSI port as an out-of-band network management application to manage the operation of each node of the chassis and power consumption. the
