Storage Spaces inside a Pool?

[thepregnantgod]

Drashna, would I make my system explode if I did the following:

 

Create a Storage Spaces Array 8TB x 6 - give it a drive letter then add that to a pool with duplication?

 

My goal is to have a fast, striped array for my media that I can write/read from but have that array duplicated automatically to the other remaining 3tb, 4tb, and 6tb drives.

 

If that would work, then how would this work:

 

I add a mkv file to my D drive, then copy it to the Storage Spaces Array lettered drive (that is inside a pool).  Would it then automatically duplicate via Drivepool to one of the other 3tb, 4tb, and 6tb drives?

Yes.

 

 

 

 

I mean, it might make my head explode, but aside from that, you should have absolutely no issue doing this.   

We'd tested this a long while ago, and yeah, there should be no issues with using storage spaces "disks" in the pool.

 

That said, if you want a fast array.... I would suggest 2x3 disk arrays, and use the SSD Optimizer.  That way, you have two "disks" to write to, rather than one (because the SSD Optimizer requires this, basically).

 

Otherwise, when real time duplication is enabled, it would write to the array, AND to one of the slower disks, and it would slow down the copy.   having two drives means that the files are written to both arrays, and then later balanced off of the arrays and onto the other disks.

Drashna, I do have 2 480gb SSDs (Sandisk Extreme Pros so not slow) as SSD optimizers.  The problem is once the files are balanced on to the array they're painfully slow to manipulate, move, change, etc.   I'd prefer to have fast read/write access to the Plex folder at all times - not only when adding to them.

[Christopher (Drashna)]

Aah, okay.

 

And in that case, yes, that would work, as well.
