After an initial setup, you want to create a new data aggregate. The node has thirty-one 4 TB SATA spare disks assigned. Your customer wants to have two spare disks.
In this scenario, which two settings would you use to reach the maximum capacity and availability? (Choose two.)
To achieve maximum capacity and availability, using ‘raidtype raid_tec’ is essential because RAID-TEC provides triple-parity protection, which enhances availability by safeguarding against three concurrent disk failures. ‘maxraidsize 29’ is selected to optimize the aggregate size, ensuring that the disk configuration fits within the specified spare disk requirement and maximizes the usable disk space. This combination ensures the best balance between capacity and data protection.
Should be C and D https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-psmg%2FGUID-2808F15F-6057-4E43-9407-5B3CA274E6C5.html RAID-TEC is the default RAID policy for capacity HDD aggregates with disks that are 6 TB or larger.
I think it should be B & D. The question asks for which option will give max capacity & availability. Using RAID-TEC + 29 disks would have 26+3 in a single raid group. Using RAID-DP you would need to use multiple raid groups to stay within best practice so you would lose capacity with extra parity disks.
