With yesterday's announcement that MS is killing off DE in the next version of WHS (Vail), I'm on a quest to find a replacement. What I'd like to get from everyone is what they would replace DE with.
Obviously, the first option is RAID. Personally, I'd go with RAID6 for the added safety net. I have considered this many times in the past and I just can't bring myself to go back to it, due to the possible migration issues if the RAID card fails.
The second option would be unRAID, but I have two issues with it. First off, it's built on Linux and I'm no expert with Linux, so I'd prefer not to have to struggle with a lack of OS understanding when I'm troubleshooting something. Second, I would need the PRO version (due to my 13 hard drives) which costs $119 and that seems a bit steep to me.
I just stumbled onto Greyhole today, which is billing itself as a free, open source, Linux alternative to DE. So far, the issues with it are, once again, Linux, and the fact that it's not in a stable state yet (according to the author).
My last known option is a return to FlexRAID, which I had been considering, anyhow, even before MS made this announcement. Previously, FlexRAID showed issues under WHS and the system load, which does seem to speak to the issues MS was having with DE. Currently, this is my first choice, but it will require some investigating on it's current state.
Any others?
