What is the purpose of an aggregate in ONTAP?

• A. An aggregate is a network interface group for traffic balancing.
• B. An aggregate is the disk pool from which FlexVols consume space.
• C. An aggregate is a set of RAID controllers.
• D. An aggregate is a software license bundle.

Answer: (B)

In ONTAP, an aggregate is the disk pool that provides storage capacity for the volumes. Disks are grouped into an aggregate and protected with a RAID policy, creating a single storage pool managed by the system. FlexVols—the flexible volumes you create for data—reside on an aggregate and draw their usable space from that pool. Space can be allocated, resized, or freed as the FlexVols use it, while the aggregate handles the underlying protection and space accounting. This is not a network interface group, not a set of RAID controllers, and not a software license bundle—the aggregate’s purpose is to provide the disk capacity and redundancy backbone that FlexVols consume.
