What is KVM for networking?

Network-based KVM, also known as IP KVM, is a KVM switch with remote management function, which can remotely operate and manage the local server in the computer room through the network, and does not need to enter the computer room again.

System: Windows 11

A KVM is a computer hardware device that allows users to control multiple computers with a set of keyboards, monitors, and mice. KVM technology does not require the target server to modify the software. This means that the target computer can be accessed at any time in the BIOS environment.

KVM provides true motherboard-level access and supports multi-platform servers and serial devices.

KVM technology has developed from the original basic SOHO office type to the enterprise IT basic equipment room facility management system. Servers and devices located in multiple remote locations can be easily and directly accessed from the KVM client management software. The Kvmoverip solution features sophisticated multi-site failover capabilities, a direct interface that complies with the new Server Management Standard (IPMI), and the ability to map local storage** to remote locations.

Analog KVM vs. Digital KVM:

Analog KVM is mainly some early products, which are used in computer rooms or local single cabinets that are not far away, and are relatively low, and have a high cost performance for small and medium-sized enterprises.

Digital KVM is an upgrade to analog KVM, because the hosts we want to manage may be distributed in various places, so digital KVM integrates IP network technology, as long as the network is unblocked, then network administrators can govern servers in any location, including hosts on the Internet.

kvm parameters:KVM Classification:

According to the network environment, it can be divided into: IP-based (KVM o IP) and non-IP;

According to the equipment environment, it can be divided into: mechanical and electronic (manual and automatic);

According to the installation method, it can be divided into: desktop and rack;

According to the working mode, it can be divided into: analog KVM and digital KVM;

According to the application range, it can be divided into three categories: high, medium and low.

KVM is a device that uses a set of keyboard, mouse, and monitors to manage multiple servers, also known as a switch, and is generally used to centrally control the servers in the computer room.

There are currently three types of products:

Emulate a KVM. The control distance is limited, and it can only be operated in front of the KVM. The switch is fast, cheap, and the market has the largest holdings.

Emulate KVM+IP control card. The controlled server can be operated remotely through the network, and the switching speed and image quality are relatively poor, so it is impossible to centrally manage, and users and permissions cannot be managed. **Higher than analog KVM, suitable for users with low experience requirements and low cost requirements;

ipkvm。The controlled server can be remotely operated through the network, and multiple remote users can access it concurrently, and up to 8 remote IP users can control it at the same time. As long as the network is accessible, it can be remotely controlled anywhere, and at the same time, users, permissions, and controlled servers can be centrally managed to have higher security.

It is suitable for computer rooms with a large number of servers, which is higher and the most convenient to control and manage.

Hello, glad to answer for you.

KVM, short for Kernel-Based Virtual Machine, is an open-source system virtualization module that has been integrated into major Linux distributions since Linux. It is managed using Linux's own scheduler, so it has very little core source code compared to Xen. KVM has become one of the mainstream VMMs in academia.

You can also understand that a virtual machine (one computer) is installed on your computer.

To put it simply, virtualization makes it possible to run multiple virtual machines on a physical server, and the virtual machines share the CPU, memory, and IO hardware resources of the physical machines, but the virtual machines are logically isolated from each other.

The physical machine is generally called the host, and the virtual machine on the host is called the guest.
