Hi!  Thanks for your work!

Just as a background, I've been using Windows 8's Storage Spaces in Parity mode with ReFS (taken from Windows Server 2012) for about 6-7 months now.  I've got 99.6% of 7.79 gigs used so I'm playing with Server 2012 R2 Datacenter (with Server Essentials role enabled), I bought three 3 gig hard drives, am going to set them up as a Storage Space using something in this desktop server, transfer everything over from the other PC/hard drives, and then steadily add some of those hard drives (basically four 1GB, five 640GB).

Although it's tempting to use NTFS and have a smaller cluster size and so less file slack, I would like to consider staying with ReFS.

http://openegg.org/2013/02/21/flexraids-raid-f-vs-nzfs/ says that both RAID-F and tRAID support any filesystem.  I just wanted to make sure before I play with tRAID tonight if it does indeed work with ReFS?

Sorry for the long intro.  I hope with or without ReFS, tRAID is what I'm looking for and I look forward to buying it when it's final  if it is.

Cheers!

If you wish to use ReFS, make sure the storage pool is set to ReFS as file system.
Outside of that, Transparent RAID is file system agnostic.

I am setting up my traid array for the first time.  To start, I added a 4 TB and 3 TB drive that are practically full of data as my first two DRUs and one 4 TB PPU.  I created the array and opted to perform the verify and sync to create the parity drive.  FlexRaid is showing a Throughput of 53 MB/s.  At this rate, it is going to take about 40 hours to create the parity for 7 TB of data.  Is this a reasonable throughput or should I be getting better performance?

I am running Win Server 2012 in a virtual machine which has 4 GB of RAM assigned to it.  I am using a Marvell aoc-saslp-mv8 sata card to connect my drives to.  All of the drives are Seagate 7200 RPM drives.

I aborted the verify and sync.  Deleted the array and started over.  This time, I opted to create the raid parity.  Now I am getting a throughput of 133 MB/s.

Something's up.  Verify and Sync in the worst case should be the same speed as Create, but on average it should be quite a bit faster.

Not really. There cases where Verify & Sync will be slower than Create and hence why Create is the default.
Verify & Sync is faster on zero'ed out drives or drives that previously were part of a parity compute.

Hi, I was looking to try t-Raid on my 2K8 R2 server, but have gotten a 404 error on the download links. I've set up and currently testing a SM server and looking for a good setup that provides protection for my data.

Lots of good info here! :)

Hi,

How many parity drives can I set? Should I always pick the biggest drive as parity drive?
I am new to flexraid/tRAID and I would setup about 12 disks with various size (250GB-500GB-1TB).

thanks

I believe as many as you want, and yes, always the biggest, or at least equal to the biggest data drive.

Spam indeed. They are getting sneakier and sneakier.
