Hello again! Quick question for you guys: Here is something from wiki I overlooked http://en.wikipedia.org/wiki/Direct-attached_storage This actually sounds like something I may be interested in. If I understand this correctly (probably not ha), these DAS controllers could allow me to share...

Understood. Seems we are back where we started. Though, I would like to know how expensive such RAID controllers (including the technology to manage the failover event) are. I think I will contact a number of storage companies and see what's out there.

Thanks again everyone! This information has helped. Yes, I am in fact going to be using SATA drives, not SCSI. After looking into taking the DIY approach, there is just one thing I am still hung up on. I am looking for fault tolerance on the RAID controller (using RAID 5). So, if my RAID...

Quite true, but I would like to avoid power issues. In fact, both of my application servers reside on separate power strips, so if I daisy chain scsi drives and comp1 dies, I will be SOL, unless I duplicate my 15 terabytes, which I don't want to do. I am looking into how much building my own...

Just thought of something else, what if your motherboard dies on Comp1? Would Comp2 be able to read and write to HD1?

Good stuff. But I have a question: Let's suppose Comp1 writes to a memory block on HD1, and Comp2 writes to that same memory block on HD1 at the same time. What happens? What mechanisms are in place to prevent such a collision? J

P5, can you name a vendor that produces a scsi controller card that allows for sharing HDs between servers? I'm looking but have not found anything yet. Thanks so much! Jared

Bozo, thanks for that. And doing that would be the optimal solution. In fact I am using DFS for file replication between two of my file servers. With that I am getting fault tolerance. Thing is, I am looking to share 15 hard disks (for a total of 15 terabytes) worth of data between two...

Hello all! I am looking for an alternative to SAN storage solution. I am looking for a raid card that can stripe an array of 15 hard disks with raid 5 and then "share" the array with a raid card on another machine. Let me explain, I have two application servers that will fail over in case of...
