This algorithm was really conceived for arrays with about 100 disks!
I don't think I'm going there anytime soon! But, it's not totally crazy to buy this 48-slot chassis and fill it up with 2TB drives. http://www.chenbro.com/en-global/products/RackmountChassis/4U_Chassis/NR4070... 2TB drives for $60 are somewhat common, so for about $5K you would have a fairly large spindle count array for testing your code. What capacity LV would that make with your raid 61 variant? Does your variant require all drives be the same size? If not, does the code support reshapping to let the LV slowly grow over time. Ie, start with 48 x 2TB drives, then replace some with 4TB to grow the LV while maintaining the data? If the code were stable, I might consider doing that in the future. If you wanted sub-1TB drives to test with, these guys sell used drives, but you would need to call them: They have inventory in Atlanta and Las Vegas. I bought a bunch (qty 50?) of 40GB drives from them about 8 years ago. They won't have drives that small now, of course. https://www.usmicrocorpretail.com/ fyi: I used to audit their disk wiping process for used drives. Every drive gets a 3-pass wipe minimum before it is resold. They have thousands of used (and wiped) drives in inventory. I don't think they sell low volumes (1 or 2 at a time), but I think they would sell 48 in a whack.
