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!
