Hello   I don't know. I would suggest that you update to the next supported release for the R720 once it is available. It is my understanding that 2.43.43.43 was released for a small number of iDRAC8 systems because we did not want to wait for the release of 2.5. I'm not sure if 2.43 was tested against any systems not on the support list. There is a disclaimer on the 2.43 download page that states do not backflash, so I would wait until 2.5 comes out for the R720 to update. If you encounter any iDRAC related issues running 2.43 then I would contact warranty support for help on how to proceed. Thanks
One of our techs installed iDRAC firmware version 2.43.43.43 on an R720 server via the web upload method. I know that this version has not been released for 12th gen servers - only 13th gen. Previously, the firmware payloads have been exactly the same size between the 2 server generations. Will there be any issues if we leave the new firmware in place? Thanks
