I am interested in building my own Direct Attached Storage box. I just built a server with 24 1.5 TB SATA drives in a RAID 6. We are using this box to store backups. Surprisingly, I think that we are going to run out of space. So the idea of a Direct Attached Storage device is appealing. I would like to build something with a similar array (24 SATA drives, RAID 6, etc).
I've searched for enclosures, and I've tried to research the technology that will allow me to connect these drives to my existing server, but it's not clear to me.
1) Opinion of the project
2) Enclosure? RAID card? Other Hardware?
3) Best way to attach the box to my existing server
Thanks in advance.
