This article mainly introduces "what hardware configurations need to be used to build a CVM". In daily operations, I believe many people have doubts about what hardware configurations are needed to build a CVM. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "what hardware configurations need to be used to build a CVM". Next, please follow the editor to study!

Although CVM is a virtual pool of cloud computing resources, building a CVM also needs to be based on huge physical hardware devices. Each cluster node of the CVM platform is deployed in a backbone computer room of the Internet, which can independently provide Internet infrastructure services such as computing, storage, online backup, hosting, bandwidth and so on.

CVM cluster nodes are generally composed of the following hardware:

Manage server

It adopts the way of dual-computer hot standby to manage all computing servers, shared storage and network of the whole node, and at the same time provide API for managing the whole node.

Management server provides: management service (computing server of management node, providing management interface to the outside), DHCP service (IP of assigning management network segment for network startup of computing server), tftp service (providing remote startup image download for network startup of computing server), nbd service (providing network block device service for computing server).

A data acquisition program is also run on the management server to regularly collect and send all kinds of performance data to the central data acquisition server. Storage server farm: storage servers can be ISCSI or x86 servers with large built-in storage capacity, which form a unified storage pool through clustered file systems to provide logical disk storage, unstructured data storage and integrated backup services for virtual machines in nodes.

Exchanger

The CVM cluster needs to be equipped with multiple layer 3 switches according to different functions and node performance requirements, which are responsible for managing network segments, public network switching network segments, internal switching network segments, storage network segments, and so on.

Computing server farm

The computing server is a highly configured quad-core server. The computing server does not need to install an operating system, but it must have the network boot function. It runs a linux micro-kernel, cloud computer software, and an Agent that communicates with the management server.

At this point, the study on "what hardware configurations need to be used to build a CVM" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
