Hi,<br /><br />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:<br /><br />Data loss<br />Cost<br />Speed<br /><br />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.<br /><br />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. <br /><br />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! :)<br /><br />Thanks!<br />--
