Subject: Building a 1pb volume

Hi,

I'm looking to build a 1PB (usable) volume on a Fedora or Redhat platform.  The volume (has to be a single volume) will be shared out by NFS.  My considerations in the order of importance are:

Data loss
Cost
Speed

I am currently considering some less expensive storage arrays using 4TB SAS disks in 5+1 RAID 5 configurations (each array would be responsible for 10 such volumes).  This will give me one level of protection.  Then I'm going to propose a DR site with a full second set of storage.  That will give me a 2nd level of protection.

Now I would like a 3rd level of protection and I thought about using GlusterFS.  If I read it right, it would duplicate the data in a way so that it doesn't reside in a single place.  

So, has anyone used Gluster?  Does anyone have any other suggestions that might work for a situation like this?  All options are currently on the table so it's play time!  :)

Thanks!
