Storage : Aggregates : Understanding aggregates : Understanding 64-bit and 32-bit aggregates
Understanding 64-bit and 32-bit aggregates
Aggregates are either 64-bit or 32-bit format. 64-bit aggregates have much larger size limits than 32-bit aggregates. 64-bit and 32-bit aggregates can coexist on the same storage system. They interoperate for some Data ONTAP features but not all.
32-bit aggregates have a maximum size of 16 TB; 64-bit aggregates have a maximum size of up to 100 TB, depending on the storage system model. For the maximum 64-bit aggregate size of your storage system model, see the
System Configuration Guide
.
You decide the format of an aggregate when you create it. By default, newly created aggregates are 64-bit.
You can upgrade 32-bit aggregates to 64-bit aggregates by increasing their size beyond 16 TB. 64-bit aggregates, including aggregates that were previously upgraded, cannot be converted to 32-bit aggregates.
