Why is it Important for a Server Console Switch to Support Multiple Simultaneous Telnet Connections?

In many server console switch applications, many different types of users may need to access the server console switch; often, several different users will need access at the same time. For example, at the same time that a network administrator needs to access the server console switch in order to change configuration parameters on an attached device, another user may also need to access the server console switch in order to retrieve buffered data that the switch has collected from a different connected device. In cases like this, it’s extremely important that the server console switch has the capability to support multiple simultaneous Telnet connections.

By their very nature and design, server console switches provide many different capabilities that may be used by many different users. The more features and capabilities that the server console switch provides, the more likely it is that several users will need to access the switch at the same time. If the server console switch only allows one Telnet connection at a time, this creates a potential bottleneck situation, that forces users to either grapple over the one available Telnet connection, or wait for unacceptable lengths of time while other users have the switch tied up.

The most obvious solution to this problem, is to make certain that the server console switch supports multiple simultaneous Telnet connections in order to allow access by several users at the same time. It’s also a good idea to make certain that the server console switch provides an adequate number of simultaneous Telnet connections to satisfy the number of users who will need access. Obviously, not all users will need to access the server console switch at the same time, but it’s still a good idea to allow for potential future users who will be added to the pool of personnel who need access to the server console switch.

Ideally, a server console switch should support about one simultaneous Telnet connection for each available serial port on the switch. This means that an eight-port server console switch should support eight simultaneous Telnet connections, and a 40-port server console switch should support 40 simultaneous Telnet connections. This “One simultaneous Telnet connection per serial port” policy is a good rule of thumb for server console switch Telnet capabilities, and should be adequate for most server console switch applications.

A server console switch provides many useful tools and generally, the longer that the server console switch is in service, the more users will discover that they need to access the switch. A server console switch that provides at least one simultaneous Telnet connection per available serial port will support most multi-user applications, and eliminate the need for users to argue over “who’s next” or wait in line until it’s their turn to access the switch.
