Console Severs And The Alternatives

A con server is an application that permits several users to watch a serial console simultaneously. This program will document information and give users the ability to gain write-access to a console in succession. It also comes along with several other advanced features. It was created to log serial traffic in order for users to go back and evaluate the cause of crashes, see any changes made to the console if any, and combine the logs with a monitoring system.

The con server multi-user features allow the system operators to trouble shoot and repair equipment together, train, and mentor as well. In addition; it has client-server abilities and when used in conjunction with a network, it affords the opportunity to work with the equipment from home or anywhere else in the world.

Specific console server applications can be obtained from many different manufacturers with several configurations to choose from. The serial port numbers range from one to forty-eight and the consoles can be used for any device on a network that has a console port.
Products that are marketed as a con server normally come equipped with a high level of security functions that only a trained professional would be able to access. Any documents that are transmitted through the Local Area Network (LAN) or across the internet are encrypted.

Promoting a product as a con server is extremely application-specific being that it denotes to what the user wants done. This is the case regardless of whether it is being control remotely, to diagnose, to monitor, or to trouble shoot and repair the equipment.
Some users choose to create their own con server with commodity computer hardware right off-the-shelf. These devices typically come with multi-port serial cards that run a smaller version operating system. This type of system is not as expensive; particularly if they are built out of components that have ceased to upgrade. They also offer more flexibility too because they give administrators full control of the software that is used to drive the device. This is including full access and the ability to configure a wider selection of security protocols and encryption values and this makes it possible to construct a more secure server.

The downside this type of con server is that these solutions may have a more expensive total cost of ownership, be less reliable, and has larger rack-space demands (providing typical industrial console servers possess the somatic component of a single rack unit whereas desktop computers with full size peripheral component interconnect (PCI) cards require at least 3Us). In the end, home-built systems could be pricier in the case of Collocation Centre Infrastructure.

There is another alternative method to a con server that are used in various cluster systems which is to "null-modem wire", as well as "daisy chain" the consoles to other idle serial ports on nodules that has other major functions.
