Raid 4
- It will protect against the loss of just one disk per raid group.
- RAID 4 will not "protect against multiple disk failures"
- If suppose some disk failed in different raid group, there won't be any data loss.
In Raid 4 Required minimum 2 disks required to create one
aggregate
One disk for data disk
One disk for parity disk
RAID 4
Example:
filer>Aggr create -r 5 -t raid4
aggr1 10
aggr1 will randomly take 10 disk from spare disk and -r 5 which means each raid group should have 5 disks
