Guangzhou ECS? What are the equipment in the machine room of Guangzhou VM configuration scheme? ECS will be built. Do you know what hardware you need? Although ECS has the word "cloud", it does not mean that it does not need to use physical devices. Today we will look at the main facilities of the cloud service room. ECS cluster nodes generally consist of the following hardware:
Switch. ECS clusters need to be equipped with multiple three-layer switches according to different functions and node performance requirements, which are respectively responsible for managing network segments, public network switching network segments, internal switching network segments, storage network segments, etc.
The management server adopts the dual machine hot standby mode to manage all computing servers of the entire node, share storage and network, and provide Api for external management of the entire node.
The management server provides: [American group station server] management service (management node server, providing management interface to the outside world for computing), dHcp service (allocating IP of management network segment for server computing network startup [ECS, recommended by Cambodia]), tftp service (providing remote boot image download for computing network startup in the server) Nbd service (provides network block device service server for computing. The management server will also run a data collection program, which will regularly collect various performance data and send them to the central data collection server storage server cluster: the storage server can be an iscsi or x86 server, with large built-in storage capacity, and form a unified storage pool through the cluster file system, Provide logical disk storage, unstructured data storage and integrated backup services for virtual machines in nodes.
The computing server is a highly configured four core server The computing server does not need to install an operating system, but must have a network boot function. It runs a Linux microkernel, cloud computer software, and an agent that communicates with the management server. We can see that building a cloud server requires huge physical hardware equipment, so when choosing a virtual machine, we need to choose a service provider with certain strength, such as our company.
Guangzhou ECS? What are the equipment in the machine room of Guangzhou VM configuration scheme? As we all know, Hong Kong VM is rented for the convenience of consumers. Generally, there are monthly, semi annual, annual and even two-year payments. Generally speaking, the monthly and annual payments for virtual machine rental in Hong Kong are the most used. So, is it better to pay monthly or yearly? Follow our company's network editor. If you rent it, the rental speed is fast, it can be used temporarily, and it can be paid monthly. The cost problem, if there is no higher cost budget, the monthly supply is better. Do not trust service providers, and worry about the quality of equipment and service items. Try it first. The monthly payment is very suitable. If the company leases, it will reduce the renewal process, save time and effort, and the annual payment will be better. It must be equipped with high-end models and enjoy annual discount.
