My  storage server has 12 HDDs.

and  RAID5 group X2

RAID group1 is on the hdd 1 - hdd 7
RAID group2 is on the hdd 8 - hdd12

According to control panel,
for each usage,
hdd 1 is system
hdd 2 is system
hdd 3 is data
hdd 4 is global hot spare
hdd 5 is data
hdd 6 is data
hdd 7 is data

and,
hdd 8 - hdd 12 are data.


My question is  this "system" meaning.
Normally, What do you predict this "system" mean ? RAID5 parity ?
 
Can global hot spare become alternative hdd instead of the not only failured hdd of RAID5 group1 but  RAID5 group2 ?
If hdd 7 and hdd 6 would be broken at the same time, the data can be recovered automatically after replacment of new hdds ?
and
what would  happen if hdd 1 and hdd 2 would be broken at the same time ?

Best regards
