Considerations for using disks from a multi-disk carrier storage shelf in an aggregate

Observing the requirements and best practices for using disks from a multi-disk carrier disk shelf in an aggregate enables you to maximize storage redundancy and minimize the impact of disk failures.

Disks in multi-disk carriers always have the Data ONTAP disk type of MSATA. MSATA disks cannot be mixed with HDDs from a single-carrier disk shelf in the same aggregate.

The following disk layout requirements apply when you are creating or increasing the size of an aggregate composed of MSATA disks:

Aggregate creation example

To create an aggregate using MSATA disks, you can specify the disk type and size but leave the disk selection and layout to Data ONTAP by using a command like this:

storage aggregate create -aggregate c1n1_aggr1 -node node1 -disktype MSATA -diskcount 14
