Questions about Software Raid on top of Windows Server 2012

post #1 of 4
Thread Starter 
I have a copy of Windows Server 2012 available and I want to to have some form of windows environment available.
What I want to do is start out with 2-3 WD Red 3tb to mainly store movies and tv shows and for streaming.
I will add more drives as they start to fill up.
I'm not really knowledgeable about raid so I have two questions.

1. Should I get a AOC-SAS2LP-MV8 card first or should I just go ahead and plug the intial drives into the motherboard hdd ports?
2. Should I use unRaid FlexRaid or FreeNAS - and what raid settings should i use?

Thanks

@OP

It's important to understand the differences between UnRAID, FlexRAID and FreeNAS. FreeNAS uses what is effectively a traditional RAID topology, but in software. FreeNAS uses ZFS which is a filesystem, volume manager and RAID engine all in one, and supports ZFS versions of RAID 0, 1, 5, 6 and 10. However, apart from RAID 1, ZFS still operates at the block level and stripes data across all of the disks in the storage pool.

FlexRAID and UnRAID achieve redundancy at the file level instead. This means that your data is "safer", because only one disk at a time is involved, no striping occurs and if you lose more disks than you have parity for, you lose only those disks, not the entire array. However, performance is limited to the speed of whichever disk holds the data you're trying to access.

One thing to be aware of with ZFS is that you cannot add disks incrementally like with traditional RAID engines, so up front planning is important.

The other thing not mentioned is that UnRAID and FreeNAS are actual Operating Systems, where FlexRaid is drive pooling software that sits on top of Windows. So if you are wanting to use Server 2012, you can forget using UnRAID or FreeNAS (unless you want to run these in a Hyper-V VM, which isn't fully supported so you will likely run into mouse/keyboard and/or network issues). FlexRAID sits on top of Windows, but it does the exact same thing as the new built in Windows Server 2012 Storage Spaces.

I say just use Storage Spaces if you are dead set on using Server 2012 (which is exactly what I would do). You can start with running drives from your motherboard, and when you run out of ports add in the AOC for 8 more drives. With Storage Spaces you have 3 options, stripe, mirror, or parity. This is the exact same thing as choosing from Raid 0, Raid 1, or Raid 5 (respectively). Start with 3 drives and set up a parity Storage Space, and add to it when needed.
