What Is iDRAC (and iLO)? Why It Matters When You Buy or Sell a Used Server
Have you ever had to drive to the data center at 2 a.m. because a server froze and nobody could get to it? If you have an iDRAC or iLO port plugged in and set up, that drive probably wasn’t necessary. That little extra network port on the back of a Dell or HPE server is one of the most useful things in the whole box, and most people don’t think about it until something breaks.
It also matters more than you’d expect when you buy or sell a used server. Let’s walk through what it is, why buyers care and what to do with it before your equipment changes hands.
Quick answer: what iDRAC and iLO actually are
iDRAC stands for integrated Dell Remote Access Controller. iLO stands for Integrated Lights-Out, which is HPE’s version. Both are what the industry calls a baseboard management controller, or BMC. It’s basically a tiny computer living inside your server with its own processor, its own network port and its own login. It runs even when the server is powered off, as long as it’s plugged in.
With it, you can power the server on and off, watch it boot, mount an ISO to reinstall an operating system, update firmware, check fan speeds and temperatures, and read the hardware logs. All from a browser, from anywhere. It’s like having a set of hands in the rack without actually being there.
Which version goes with which server
Every server generation ships with its own version, and that version tells a buyer a lot about how old the box is. On the Dell side, iDRAC7 came with 12th generation PowerEdge servers, iDRAC8 with 13th generation, and iDRAC9 covered a long run from 14th through 16th generation. Dell’s 17th generation PowerEdge servers moved to iDRAC10.
HPE follows a similar pattern. iLO 4 shipped on Gen8 and Gen9 ProLiants, iLO 5 on Gen10 and Gen10 Plus, iLO 6 on Gen11, and iLO 7 on the newer Gen12 systems. HPE keeps its iLO documentation in one place if you want to dig into a specific version.
So when a buyer sees iDRAC9 or iLO 5, they already have a pretty good idea of the CPU platform, the memory type and how much life is left in the server.
The license part nobody remembers
Here’s where it gets interesting for value. Both iDRAC and iLO come in license tiers. The basic tier handles the essentials, but the good stuff like the full virtual console, virtual media and advanced monitoring usually needs a higher license. On iDRAC9 that’s typically Enterprise or Datacenter. On iLO it’s iLO Advanced.
Not so fun fact: a lot of companies paid for those upgraded licenses years ago and completely forgot. The license is usually tied to the server itself, so it stays with the hardware when you sell it. A used PowerEdge with an Enterprise license is easier to resell than the same box without one, because the next owner doesn’t have to buy the upgrade. That can nudge your offer up, so it’s worth checking before you request a quote. You’ll find the license level right on the iDRAC or iLO dashboard.
What buyers look at in the logs
iDRAC and iLO both keep hardware event logs, and a smart buyer reads them. They show memory errors, failed drives, power supply faults, overheating events and more. A clean log tells a buyer the server lived a quiet life. A log full of correctable memory errors on one DIMM tells them to plan on swapping a stick.
If you’re the buyer, this is one of the best tools you have. Before you commit to a used server, ask the seller for a screenshot of the system event log and the firmware versions. If it’s in front of you, boot it and look yourself. Our guide on what to check before buying a refurbished server covers the rest of that list. If you’d rather skip the homework, our refurbished servers are tested before they ship.
What to do with iDRAC or iLO before you sell
Your remote controller remembers things about your network. It may still have your IP addresses, admin usernames, passwords, alert email settings and sometimes directory or certificate settings configured. None of that should leave your building.
At a minimum, reset the controller to factory defaults so your credentials and network settings are gone. Dell also has a built-in System Erase feature on newer PowerEdge servers that can wipe the controller settings, BIOS settings and attached drives in one pass, and newer HPE servers have a similar secure erase option in iLO. Those are handy, but they don’t replace a documented drive wipe if you need proof for an audit.
If that feels like a lot of extra work, it’s fine to leave it to us. Equipment we buy goes through certified data erasure with our sister company DES Technologies, and we can document it for you. Our checklist on what to check before selling your used server equipment covers the rest of the prep.

Frequently Asked Questions
What is iDRAC on a Dell server?
iDRAC is the integrated Dell Remote Access Controller. It’s a built-in management controller with its own network port that lets you power the server on and off, view the console, update firmware and check hardware health remotely, even when the server is off.
What is the difference between iDRAC and iLO?
They do the same job for different brands. iDRAC is Dell’s remote management controller for PowerEdge servers, and iLO is HPE’s version for ProLiant servers.
Does the iDRAC license transfer when I sell a server?
In most cases, yes. iDRAC and iLO licenses are usually tied to the server hardware, so an Enterprise or Advanced license typically stays with the server and can make it easier to resell.
Should I reset iDRAC before selling a server?
Yes. Reset it to factory defaults so your network settings, usernames and passwords don’t leave with the server. The drives still need a proper wipe, which we handle for equipment we buy.
