First, I appologize for bringing up such an old post, but it came up in a Google search! lucky me!
I have found a business use for the server and fiber storage, and will be looking at renting some high-speed WAN access business space in town.
Like I said before, I'll need 3 enclosures. The HDDs I have are made by Hitachi, so they may not work in the HP EVA enclosure box?
However, I'm still confused at the HBA to enclosure connection process. I will only be using one host machine, with a dual port HBA. Is the 2nd port on the HBA only for high availability, or for a speed increase too? Given that I wish to obtain a EVA or MSA RAID controller, how would all connections be made? I understand that enclosures are to be wired in series, correct? So I would go from controller to one enclosure, to the next enclosure, to the last one, then back to the controller? Then one connection (or two?) from controller to HBA?
All SFPs and cables will be LC style.
If I wanted to eliminate the controller and do host based RAID processing, how would the wiring be different?
Again, Thanks for all of the wise advice.
