A data-center technician reports that a rack-mounted server at a distant colocation facility will not boot because the OS disk is corrupt. The site is unstaffed outside business hours, and corporate policy forbids attaching any physical media to the server. The only reachable interface is the server's dedicated BMC port on a separate management VLAN. The administrator must boot a Windows Server ISO that resides on their notebook and reinstall the OS without travelling to the site. Which out-of-band management feature should the administrator use to make the ISO appear as a local DVD drive during POST?
Virtual media (remote drive/ISO) redirection through the BMC
Remote (virtual) media, sometimes called remote drive access, allows a BMC such as Dell iDRAC or HPE iLO to map an ISO file or local USB device over the network so the server BIOS/UEFI treats it as a bootable optical or USB drive. This lets an administrator reinstall an OS even when the production network is down and no removable media is present on-site. Serial-over-LAN and remote KVM provide console or keyboard/video access only, while a power-cycle command merely restarts the system; none of those alternatives can present bootable installation media to the server.
