Server is Unresponsive or Crashed Without iLO : If the server crashes or becomes unresponsive (e.g., due to a kernel panic, hardware failure, or OS-level issue), you won’t be able to log in via traditional methods like SSH, Remote Desktop, or console access. With iLO : iLO operates independently of the server’s operating system. Even if the OS has crashed or is hung, iLO allows you to interact with the server, reboot it, or troubleshoot the problem from a hardware perspective. 2. Remote Power Control Without iLO : If the server needs to be restarted (e.g., during a crash or firmware update), you would need physical access to the machine to press the power button or connect to a local KVM switch. With iLO : iLO allows you to power on, power off, or reboot the server remotely. This can be done ev...
