Thanks a bunch steve, your review was great...Now about Levels 1, how is
that a different matter? (Good/Bad/Etc) I found a couple 2U cases with
two hot swap bays on the front - which might be the most economical route
for having a drive redundancy for a server farm - rather than having one
shared storage for a number of servers. I'm definately looking at a
hardware based solution, I actually want to use the same boxes for a
couple FreeBSD machines a client is going to need as well. Between
mirroring and parity, how do the hotswaps compare?
I appreciate your time,
Eric
