Hi all, Sorry for the OT. I've got an IBM N3300-A10 NAS. It runs Data Ontap 7.2.5.1. The problem is, from the docs it says that it only supports either RAID-DP or RAID4. What I want to achieve is Max Storage Capacity, so I change it from RAID-DP to RAID4, but with RAID4, the maximum disk in a RAID Group decrease from 14 to 7. In the end, either using RAID-DP or RAID4, the capacity is the same.
Now, why RAID5 is not supported? I believe using RAID5, I can get more storage capacity, can't I?
Design/marketing decision for the features of the board?
I also notice with some onboard RAID controller, they only support either RAID0, RAID1, or RAID1+0. No RAID5.
They do not want to go through the trouble of implementing raid5 for that particular board or they want raid5 to be available on more expensive options or ...etc
What's wrong with RAID5, is there any technical limitation with RAID5?
Not with the technology itself. They are just not offering raid5. If you have a problem with that, get another product or go to another company.
