In-Band Management vs Out-of-Band Management (OOBM)
- In-Band Management: the ability to administer a network via the LAN.
- Out-of-Band Management: accessing and managing network infrastructure at remote locations, and doing it through a separate management plane from the production network.
- provides a secure dedicated alternate access method to administer connected devices without using the corporate LAN.
- available even when the network is down, or the device is off.
- can be used to remotely reboot devices.
Lights-out management (LOM) is one form of OOB management. (e.g. HPE's iLO)
During system or network outages, a Console Server is a single hardware solution that provides secure OOBM to monitor IT assets and devices from multiple vendors. The Console Server gives administrators access to multiple USB, RS232, or Ethernet console management ports from anywhere, anytime, and any platform, as if they were locally connected through a direct connection. They can be used to reconfigure, reboot, and reimage remotely across the internet or WANs.
