Oobi
OOBI stands for "Out of Band Infrastructure" and describes a term from the field of network technology and describes the redundancy of access to a network component
The opposite term is in band .
Demarcation
Out-of-band means that the control signals are not sent on the same communication path as the data, in contrast to this, in-band means that the control signals are not sent separately with the data.
background
So-called out-of-band infrastructures are set up in order to be able to access the affected systems and to carry out remote maintenance in the event of a failure of network components, which can also affect LAN or DSL connections . In the event of a failure, these infrastructures offer the possibility of accessing network components that are inaccessible via normal communication channels.
By setting up such an infrastructure, in most incidents there is no need to send an employee to the affected system for maintenance work. Above all, this saves time and money.
In the event of an absolute emergency, it is possible to use power management modules and the IPDU protocol (Intelligent Power Distribution Unit) to disconnect the power connection from servers or to restart them hard.
history
Out of band infrastructures are not a new phenomenon; attempts were made at an early stage to create redundancy. In the beginning, this was implemented using RS232 , but the possibility of redundancy has now increased. Nowadays, in addition to the USB interface, Ethernet and fiber optic connections can also be used.
Nowadays the term out of band infrastructures is mainly associated with keyboard video mouse switches and intelligent platform management interfaces .
