How to choose a KVM solution (1)

Based on years of experience in the implementation of each business to choose the same KVM solution, mainly due to: 1, KVM's rapid development of options you can have analog, digital, and digital-analog combined with the program; 2, KVM System management feature-rich, whether it is analog or digital KVM systems have the management capabilities and rich connections, which can be reflected in your management needs and cost-effective on the KVM system, so what kind of KVM solutions is your best choice, the general need to consider the following factors:

1, the number of servers: the number of servers involved in this issue and its expansion to the KVM system configuration or connection, which involves the management and cost-effective, especially when the number of larger, often demand more complex, more flexible solutions.

2, the administrator and the number of users: the use of KVM centralized management because it is after, it involves the use of the number of users, to be able to meet the users to control servers within their competence, not the same as the business administrator or the specific user is also relatively large differences in the flexibility to solve the problem, the general increase in cost can be.

3, visit the channel number: blocking rate, that is, multiple users at the same time the use of KVM system obstruction caused by later users can not visit the KVM device, so visit the channel by the combination of administrator and end users to determine the number of management, based on enterprises to identify the specific circumstances of a number of best management terminal by the management terminal to determine the number of KVM equipment.

4, the security issues: speaking from the transmission, digital signal than analog KVM, because the analog signal transmission products are keyboard, mouse, display digital signal, the network was easy to steal, a lot of security risks and how encryption of these signals is critical, the number currently on the market the way KMV encryption: SSL, DES, 3DES, some encryption method such as the existence of security risks 128SSL, so before buying equipment KVM must understand clearly. Transmission security is not only manifested in the encryption method, the most advanced equipment used KVM Video incremental transmission mechanism, only changes in the video transmission of the signal from a security sense, even if it can not be stolen, a strong guarantee of the safety data .

The safety of not only the security of output data, as well as user account security issues, as the KVM is based on the IP network is an open system, so user accounts are also people with ulterior motives have been hacking through a variety of network monitoring tools or the possibility of theft, the current user authentication 128SSL protocol is commonly used, but the authentication system can support the KVM industry-standard X.509 certificates and AAPI / SSPI agreement is a measure of the highest standards of safety certification. In addition the system depends on the concentration of KVM management system hot backup capabilities, and how easy to maintain, in particular, whether the user self-maintenance is very important.

In addition to transport security issues, with the high-end KVM, since the conversion is the use of specialized interface with the server connection, so there is not a conversion interface is activated to send KVM signals and storage of information such as permissions as a standard to measure the system security.

5, management: the way into analog and digital management, and the figures can be divided into special software or browser access, centralized management system is currently available in the market are software and hardware, as well as certification of non-systematic direct access to KVM devices, the existence of security risks, and so on, so what kind of management style suited to your needs carefully before buying a variety of ways to understand the benefits or drawbacks. In general the use of centralized management software, more because of its ability to heat back up and encryption is strong and easy to maintain, so a relatively high security.
