Can I run a premium capacity pool license on HDD as backing storage?
Applies to
- ONTAP SELECT
- Capacity Tier License
Answer
- No , This is unsupported configuration
- License Types Overview:
There are two types of licenses available for ONTAP Select:
-
Capacity Tiers:
- Type: Perpetual License
- Binding: Locked to a single node
- Renewal: Requires periodic renewal of the support contract
-
Capacity Pools:
- Type: Term-based License
- Binding: Locked to a specific License Manager instance
- Scope: Applies to a storage pool, which is a collection of nodes
- Renewal: Needs to be renewed near the expiration date
License Flavors:
Each license type is available in three distinct flavors:
-
Standard Capacity Pool License:
- Supports deploying ONTAP Select on a small VM instance (4 CPUs, 16 GB memory)
- Uses HDDs as backing storage
-
Premium Capacity Pool License:
- Supports deploying ONTAP Select on a medium VM instance (8 CPUs, 64 GB RAM)
- Uses SSDs as backing storage
- Supports Software RAID deployments (enforced by Deploy at the time of provisioning)
-
Premium XL Capacity Pool License:
- Supports deploying ONTAP Select on small, medium, or large VM instances
- Uses either HDDs or SSDs as backing storage

Understanding Drive Type Determination:
ONTAP Select (OTS) determines the drive type during the deployment phase based on the ESXi-side configuration of the datastore:
-
- OTS determines drive type initially (during deploy), based on the ESXi-side configuration of the datastore, either "Flash" or "HDD".
- When OTS is deployed on HDD datastore, it shows disks as type VMDISK.
- When OTS is deployed on SSD/Flash datastore, it shows disks as type SSD.
