Back in the beginning of 2008, I purchased my first SuperMicro 846 24 bay chassis with dual 900W power supplies. I loaded it up with 24 1 TB Seagate Enterprise drives, all controlled by an Areca 1170 RAID controller running RAID 6.
Here's the chassis:
And the internal wiring:
In August 2009, I upgraded the mobo to a SuperMicro x7dwn+ running Windows 7 Ultimate.
At this time I also added a Areca 1680 controller and a SuperMicro 846E 24 bay chassis, loaded up with 2 TB Hitachi consumer drives. This was also setup as a single RAID 6 array.
Over the last 4 years, I lost maybe 3 of the Seagate Enterprise drives (ST31000340NS), in the 24TB raid, but I always kept spares on hand and rebuilt the raid no problem.
The 48TB raid however, has given me several issues. Sometime during a reboot (generally only from extended power outages), the controller will loose the chassis, and I have to fiddle with the cables and do multiple reboots to get it back. I have also lost about 10 drives now (fortunately all replaced under warranty), but that is about to expire and the failure rates have been steadily increasing to the point where I'm loosing a drive now on every other rebuilt.
So, I'm thinking it's time to move from these colossal enclosures (which also consume huge amounts of power with 4 900W power supplies running 24/7).
I'd like to move to independent 1 or 2 U chassis, each containing 6 drives in a RAID 5 configuration and then network raid them all together across my network and have each "node" on the network go to sleep when not in use and use WakeOnLan. I'm using MyMovies btw, for my rather large collection of Movies and TV Shows, btw.
So any suggestions on what's available, preferably free that I can hack together myself?
