New systems are shipped with the root volume in a 64-bit aggregate starting with which Data ONTAP release?

Data ONTAP 8.0.0 did not ship root volumes in 64-bit aggregates by default - 64-bit aggregate support existed but was not the default for root volumes.

Data ONTAP 8.0.1 still did not make 64-bit root aggregates the default shipping configuration for new systems.

Data ONTAP 8.0.2 continued to ship root volumes in 32-bit aggregates by default - the change to 64-bit default did not occur until 8.1.

Data ONTAP 8.1 introduced the default behavior of placing the root volume in a 64-bit aggregate on newly shipped systems, enabling support for larger aggregate sizes and more flexible storage layouts. Prior releases used 32-bit aggregates for the root volume, which imposed capacity and scalability limits. This change aligned with NetApp's broader push toward 64-bit aggregate adoption for improved scalability.
