AFF-A220 recommended drive assignment for RAID

MarcusSerrao — Wed, 04 Jun 2025 09:53:46 GMT

hi.

We recently purchased the SAN with 12 x 960GB SSD for our production vSphere environment.

As we are not familiar with how to assign the number of drives per node (2 nodes on the A220), is it safe to say the recommended and most generic configuration would be 6 drives per node in a 1 TB RAID6 configuration?

regards.

The AFF has a feature called ADPv2 which partitioned each disk into 3 partitions. Root-Data-Data.

https://docs.netapp.com/us-en/ontap/concepts/root-data-partitioning-concept.html

There's also no RAID6 with ONTAP, it'll be RAID-DP.

Default is best. You'll end up with 2 data aggrs, 1 per node with 11 disks (partitions)+ spare. each will be approx 3.3TiB in size.

@SpindleNinjais right on...

If you'd like to see the exact sizes of the partitions, the NetApp Hardware Universe shows that information via the ADP Root Partition Configuration link of the AFF A220's search results:
