Qsan provides a monthly updated compatibility matrix for all customers to check which disk models have been tested and verified on which Qsan storage models. The compatibility matrix is downloadable from Qsan partner portal. We also suggest using Enterprise level disks on all Qsan products to ensure the durability as most of the desktop drives are aredesigned for 24x7 usage and might also have durability issue in multiple disks environments with stronger co-vibration factors.
The S.M.A.R.T. is a monitoring mechanism on SATA disk, a SAD disk uses its own reporting mechainsim for disgnostic purposes. Thereofore so it is normal that on SAS disk you won't see any S.M.A.R.T. values, though some basic information such as disk temperature can still be reported.
