I’ve really only been paying attention to updating iDRAC and BIOS firmwares when I get a new server. But in the example case of like a Dell R720, is there any tangible reason to care about updating the firmware of other components? And if so, which, and why?
For most dell systems, idrac, bios, CPLD, raid controller, nics, all have firmware updates that should be applied. Power supply sometimes, not usually necessary.
But R720, don’t do it. T620 don’t do it. R620, don’t do it.
I haven’t had any issues before or after that cursed xx20 generation.
