Out of band management is a dedicated channel for managing devices that is also known by lights-out management or LOM. The administrator with this system has the ability to watch and even manage changes on the network. This can even be done when the machine is not on. However, this process is limited due to the fact that the devices need to be functioning fully in order to be manageable.
In order for an administrator to remotely manage the servers for the network and routers, they will need to have access to the system that is unrestricted, which if not available can result in loss of access to the device. LOM can help correct the problem by utilizing a channel that is separate from the channel where the main data is contained.
SoC stands for System-on-Chip and is a modern way to manage systems with a different Ethernet connected. This separate connection has its own settings and IP address and can still work even when the network is shut off. The connection to is encrypted to keep it safe and eliminate the need for extension cards.
Basic Components of Management
a complete LOM system needs to have the LOM module (a hardware device). It should also have a program to allow continuous monitoring of the related variables. Another option is a Remote Access Card which is costly but effective for computers with their own processors and memory. If you have an LOM with multiple servers, the administrator can access the consoles that are on the network. This allows them to fix network issues no matter where they are.
