Ok I think the time (and budget) has come to give Linux a serious look on my network. I am currently in the process of building a new NAS storage point. The entire goal of this storage is to act as a backup location for Symantec Backup Exec. For hardware I am using an Intel SR2612URRNA server with 12 2TB drives in Raid 1+0. The hardware part is easy for me, but when it came time to choose an OS I ran into a bit of a conundrum. I'm comfortable within the MS environment, but I don't really need or want a full blown Server 2008 R2 install here. Also I'd really like OS level Deduplication. I now Backup Exec has a version with deduplication on the client side, but I cannot imagine that is a cost effective way to do it. Plus I'd like the hardware to be easily switched to whatever backup software we choose in the future.
So now my actual questions. First what is the best Linux build to use as a simple NAS? Since I've never even installed a Linux distro I'd prefer a consolidated package. I've heard opensolaris supports is natively, but there are other projects out there. Any recommendations?
What I'd really like is something very easy to install that can be easily seen as a network share on my AD domain. Burn the ISO, hop through a wizard and good to go would b nice. However I just don't know if Linux is there yet.
