Thanks. For future : I want to use EMC because of price. My emplyer
has big price reduction.
All servers will be conected through Brocade FC switches.
I don't want to mount one LUN to few servers. But i'm need to
be able to mount this LUN only once but every server need to by able
to mount this. I'll read everything you propose and then i'll write sth.
I hope you understand.

Thank in advance
