Hi,
I have about 40-50 3TB drives and my plan was to have them connected in a giant pool with much of it being used as 20-40TB virtual disks created as dual parity. I was planning on leaving about 10TB RAW free on the storage space so that on a disk failure storage spaces would have enough room to auto repair.
I can't seem to find a recommendation for the max number of drives to have in a pool to maintain a healthy safety margin. I know, or at least think I know, that this does not really have an analogous comparison with a HW RAID controller. Does anyone have a recommendation for this?
Also, I have 5x500GB SATA SSD's that I want to use with this pool. I was going to create tiered spaces with a small 3 way mirrored for each virtual disk but maybe it's better if I just set them as Journal drives? I think as Journal drives they will server as a write buffer to all the virtual disks in the storage space.(?)
This entire pool is primarily for media storage. At one point I was thinking I was just going to make a single massive virtual disk but I figured it would be a pain to work with. But maybe not...
Thanks for taking the time to read this. I hope it's reasonably coherent; you would think I would learn about creating posts at 4:30AM.
