Hi @DewayneD,
There is no detailed documentation for the internal USB module for R250. The only information for the USB are it is an internal boot module similar to IDSDM and it's 3.0-compliant.

Hi @DewayneD,
No no, the ISO in mass storage such like in the USB is already "mounted" on the server cause it's already in the server. You will not be able to use the ISO in the USB on your iDRAC interface. You use the internal USB as if you install OS by using an external USB port.

The internal USB memory key can be used as a boot device or mass storage device.

The reason I asked is because I read a few places that you do not want to boot to SD cards unless they are installed from the factory. I was curious if there were any similar issues using the USB. I actually thought it might be a good place to keep ISOs for emergency remote re-installations.

Hello @DewayneD,
Well, yes and no on the factory install. As a Dell technical support, it would be recommended to have the OS installed in factory but I do see users in this forum installed their preferred OS on the SD cards, some successfully, some don't. Yes, it's good to keep a copy of the OS locally, just in case of emergency.

Can it be used for both? Should I be able to put multiple ISO images on the USB and boot from them? I can see that I can mount an ISO from my workstation or from the network. So should I be able to select one from the internal USB?

Hello DewayneD,
Documentation shows it listed under- Storage Controllers: Internal boot devices.
*Boot Optimized Storage Subsystem (BOSS-S1): HWRAID 2 x M.2 SSDs 240 GB or 480 GB
*Internal USB board
*Internal Dual SD Module
I suppose you could put whatever you want on it. It should just show up as storage.
CAUTION: To avoid interference with other components in the server, the maximum permissible dimensions of
the USB memory key are 15.9 mm width x 57.15 mm length x 7.9 mm height.

Let’s me clarify. Should I be able to put multiple ISO in the drive and mount them to install?

Hi @DewayneD,
Honestly, I've not tried the internal USB OS installation before during my time with a spare unit. Usually I would use iDRAC Enterprise, virtual mount device, though if you're remotely doing it, it may take some time to transfer the file to the iDRAC from your client device. I did you it for device firmware updates with multiple .exe files. Assumingly, it acts like a mass storage, hence, you should be able to store multiple ISO.

My thought was that the ISOs would be available locally within the Server for future deployment. But when using the iDrac interface, I don't see a way to access the USB device when trying to mount ISOs or IMGs. I can select on the local workstation or on a network share. But it looks like to connect to an ISO on the server, it has to be a bootable ISO.
