You are creating a new aggregate with one RAID-TEC RAID group.
How many parity drives are used in this scenario?
You are creating a new aggregate with one RAID-TEC RAID group.
How many parity drives are used in this scenario?
When setting up a RAID-TEC RAID group, three parity drives are used. RAID-TEC is designed to provide triple-parity protection, meaning that it can tolerate the failure of up to three drives without data loss. This configuration offers a higher level of fault tolerance compared to other RAID types, which typically use fewer parity drives.
B...should be answer
It's 3 Parity for the TEC and 2 for the DP
B You can convert from RAID-DP to RAID-TEC for triple-parity protection, or from RAID-TEC to RAID-DP when a smaller aggregate no longer needs triple-parity protection https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-psmg%2FGUID-43A74B36-A732-40A4-889A-A89B8F827FF2.html
