G'day Grunt,
The DSS Lite is offline until at least January, so even if you get the key creator it won't activate.
If you download the Demo CD it will run for a while, just don't make more than 1TB available to DSS. Otherwise when you revert to DSS Lite in Jan, it will not work.
Not sure what you are asking with "USB ISO is tested on DSS DEMO ? "
I have read that there is a solution to boot from USB on these machine. Could you send me ISO?
Someone says that he needs a solution to boot a DL380 G3 without DVDRom, I only know one posibility, to install an USB Floppy, perhaps a USB DVD will work but I'm not sure.
