BTW 2 . I thought, the max. filesystemsize is 1EB and not 16TB.

The max FILEsize should be 16TB ...

Apologies for missing to give you the link

http://www.redhat.com/rhel/compare/

Check under "Filesystems and Storage Limits" section.

An one more thing: forget 32 bit here. Use 64 bit only.

Thx. Yes I'l usually go with 64 bit only.

BTW 3. So far I found the information, that the 1EB ist the theory, but
the usertools for managing the ext4 are limited to 16TB for safety
reasons...

Another important consideration would be, if and when the organisation
needs support and are ready to pay for it, say, only for production
systems, Redhat has always been there.
