Q: I didn’t see the RAID type selection in SSD Cache acceleration function in QuTS Hero,is this normal?
A: Yes, this is normal. In QuTS Hero, only Cache Type can be changed in Cache acceleration setup.
Depending on the number of SSD and Cache types selected, the system will set up different RAID types accordingly. Please refer to the table below.
| The number of SSD | Read Cache | Read Cache and Write Log (Read Write Cache) |
| 1 | Single disk | Not Support |
| 2 | Stripe (RAID 0) | Mirror (RAID 1) |
| 3 | Stripe (RAID 0) | Not Support |
| 4 | Stripe (RAID 0) | Stripe of mirrors (RAID 10) |
Note: If the cache type is set to Read Cache and Write Log, you must select an even number of disks.
