Spare non-mirrored sleds
Exhibit 6.5-2 QuickRaid10 first spans drives across sleds, then partners sleds into mirrored groups, then enables
striping across the mirrored groups.
All configurations will not be available if the array has fewer than 24 physical drives in 12 physical sleds.
For example, QuickRAID 10 1 will only work with a fully populated array. QuickRAID10 3 will work if sleds
9-12 are removed: LUNs 1 and 2 will be available but LUN 3 will not be available.
