With 64-bit aggregates, the number of FlexVols that can be created on a storage controller is ____.

• A. 1000
• B. 500
• C. 6400
• D. 64000

Answer: (B)

With 64-bit aggregates, the system places a per-controller cap on how many FlexVols can exist, and that limit is 500. The reason for this isn’t the capability to address larger disks or more space—64-bit addressing unlocks larger capacity and more extensive metadata, but the control plane still enforces a practical ceiling on the number of separate FlexVols a single controller can manage efficiently. Each FlexVol brings its own root and metadata structures, so keeping the total under 500 helps ensure predictable performance and manageable memory/metadata usage. If you need more FlexVols, you’d split the workload across additional controllers or use a multi-controller/clustered setup to distribute volumes, rather than pushing a single controller beyond this limit. The other numbers would exceed what NetApp designs as a safe, supported maximum for a single controller in this scenario.
