Disk Spare Ratio Question

[Wazan]

Hi Team,

Do we have a formula to calculate spare ratio per number of disks in the node for SATA or SAS disks

I found some KB for SSD .I'm looking for the same for SATA or SAS disks.

Example KB for ADP

number of spare per number of disks per node.

Actually, if you review the KB, it applies to both HDD and SSD. The commonality is disk partitioning, which pretty well the default for most systems.
