Hi All,

I try select below set size and I have no idea why INC display "4+2" estimated free system spare same as "8+2" and "4+2" more than "6+2" and please review attachment, anyone have idea?

"RAID Set Size (Data + Parity)" "Estimated free system spare (TB)" "VV size "(TB)
"10 + 2" "1.8" "7.9"

"8 + 2" "1.5" "7.9"

"6 + 2" "1.1" "7.9"

"4 + 2" "1.5" "7.9"


Best regards,

Chung

The reason will come down to balancing and how well it can do that across your system. For answer any deeper, I would need to know:

How many FC PD's do you have?
How many drive chassis do you have FC PD installed into?
How many controller nodes do you have?
