Oops, didn't write that the master/media server will have 4x 1 Gbit
NICs & 8x LT03 tape drives. Using the document I arrived at 8 CPUs &
4.6 GB RAM

Trying to get a server that can handle the NICs & tape drive at full
tilt & peoples experiences with using this document or other methods
of sizing

Regards
Michael
