iDRAC: Integrated Dell Remote Access Controller
iDRAC is Dell's dedicated out-of-band management controller built into PowerEdge servers. It runs on its own processor and network port, letting admins power-cycle, reinstall, and monitor a server remotely even when the OS is down or the machine is powered off.
iDRAC is a system-on-chip that operates independently of the main CPU and operating system. It exposes a web UI, an SSH/IPMI interface, and the Redfish API over a dedicated Ethernet port or a shared LOM port. Through it you can mount virtual media, view the console via HTML5, read hardware sensors, and update firmware without touching the physical machine.
Feature depth depends on the license tier. iDRAC Basic ships free, iDRAC Express adds more monitoring, and iDRAC Enterprise (or Datacenter) unlocks virtual console, virtual media, and Lifecycle Controller automation. Generations track the server: iDRAC7 (12th gen), iDRAC8 (13th gen), iDRAC9 (14th–16th gen), and iDRAC10 on the 17th-gen R670/R770 (2025 onward).
When sourcing Dell PowerEdge servers from China, confirm the iDRAC license tier in writing. Many refurbished units ship with Basic only, and virtual console plus virtual media (the features you actually need for remote reinstall) require an Enterprise license that costs extra to add later.
