Aggregate — Collection of physical disk space used as a container to support one or more flexible volumes
– Aggregates are the physical layer
Terminology
A traditional NetApp volume is made up of two layers – physical and logical. In Data ONTAP 7.0 (7g), we have separated the two layers. An aggregate is the physical layer. It is made up of a collection of disks organized in one or more raid groups and is used as a container to support one or more flexible volumes.
