We understand you would like to update the firmware in all of your SSDs so they can be in the same version. Checking the case, we need to inform you that for the ones you were able to update the firmware from N2010101 to N2010112, those are retail drives that you can update using the Intel® Data Center Tool.
Now, the other drives with firmware: N201DL41, those seem to be Dell OEM (Original Equipment Manufacturer) drives, a reason why you cannot update the firmware on it. Our tool only works with the retail version of SSDs; for the OEM drives, you need to check with the manufacturer of the disk for the proper tool to update the firmware and also, this one will be different from the retail units.
Please let us know if you need further assistance.
