Hi Mens,
it's exact that filers can't exceed 6TB but we can have eaysyly performance
(pretty so good) with their.
If you try to have EMC box or IBM, you will have to manage anything that
it's not your job (IO for example).
I think that netapp can be a very simple solution (where other man sells
complexity)
Thanks
Fab.
