Right, as a little summer project i'd like to consolidate all my silly USB/FW800 drives into a low power, high reliability backup server.

It will be used for the following:
1. Time Machine backup from Mac Pro & MacBook Pro.
2. Video streaming.

It essentially should be able to do what the Drobo does, except quicker and cheaper.

1. Add a new HD it dynamically sorts it out so I don't have to fiddle with it.
2. Automatic rebuild of the array if a disk fails and I bug another one in (Perhaps two disk failure redundancy?)
3. The array of disks must show on the network as one continuous disk, if it doesn't then it's not what I want. This is a requirement for time machine to work (It needs enough space to backup everything in the mac to one place, this will eventually be many TB.)
If I have 6TB of data I need a continuous 6TB to backup to, even if it's 3x2TB, etc.

4. The ability to privatise different folders. For example I want the iTunes folder to be accessible throughout the network, but the time machine to just be available with a login.)
5. Wake-on-Lan & low power - Turns itself off at night, turns itself back on when I turn any of the computers on. My router supports WOL as does my airport extreme which will act as the gigabit hub.


Been reading up on UnRAID but not entirely convinced it will do what I want.

What do you gurus of solutions think?

The problem/difficulty in your requirements is the drobo like RAID functionality. I think as you've found out that unRAID does something similar. On the down side its all propriterary etc.

Other options include....

FreeNAS
OpenFiler

You could also just buy a good hardware RAID card which would improve performance over any of the other solutions and use plain old Windows.

In terms of hardware, you cant go wrong with a HP Proliant Microserver (see other huge thread in here). This will give you 8tb out of the box as raw capacity (4x2tb).

Well from my further reading it seems to do pretty much everything I want (unRAID that is).

Besides, 4-6 drives isn't enough. I have 5 already, and it will be 7 by the end of the year, so it has to be a self build of some kind.

I'm thinking about the following:

* Denotes need to buy!

2TB WD Black = Parity*
1TB 7200RPM Hitachi = Cache
3x2TB Greens = Data
1.5TB Samsung = Data

Should do the trick hardware wise.
 
If you don't need RAID5 and can go with RAID1s or RAID10 then you can get a decent 8port hardware RAID card for about £150. Which would be best for a larger number of drives. Software RAID tends to suffer performance wise when you start having >4 disks and multiple arrays. Plus a Hardware controller will do all the auto-rebuild stuff you want to do.
 
I've been using unRAID for a 2 years now. Use it for video streaming, iTunes and storing backups of my PC and apple systems. I built it out of old bits I had lying round and a few new large HD's, certainly isn't as fast as Hardware based RAID systems I use at work on a daily basis but for home use is more then fast enough. Did have a disk die about 9 months ago, powered it off stuck in a new drive and let it rebuild and has been happy ever since.
 
Been using unRAID happily for quite some time now.
You can even run VirtualBox on there now which opens up a whole world of possibility :D
I'd say unRAID ticks all your boxes.
 
Well I've bought a few bits and pieces

Asus mobo + AMD Athlon 250 + Coolermaster Case + BeQuiet PSU.

Memory is from my Mac Pro, disks will be:

3x WD20EARS
1x WD10EARS
1x Hitachi 7K1000 for Cache
1x Samsung HD154U

Beast should be running next week :D
