data replication how to

[Yohann Desquerre <yohann.desquerre@wanadoo.fr>]

hi all,


I 'd to promote the free software at my job, i 'am trying to make my 
bosses trust in a free sofware solution to replicate 7TB from an hitachi 
storage product to a STK one.



Here is the things i had to do that :

1 x86 server (debian for sure !)
1 fc switch brocade 3800
2 fc pci board (qlogic 2340)
and so
1 hds9960 (Hitachi storage product)
1 STK B220 (STK storage product)


i think i would plug the 2 storage product and the debian  into the 
switch and then use unison to replicate the data (or do a snapshot)...


i am open to all the proposition you could do


ps ( it must be finished in less thant 12 hours)


thanks for help
