Considerations for sizing an ONTAP Select Capacity Tiers license

PDFs

The Capacity Tiers license is based on the underlying disk capacity managed by each ONTAP Select node and not the usable capacity of the node, HA-pair, or cluster. Each Capacity Tiers license is assigned to an individual node serial number for a specified capacity and requires an accompanying support contract.

The licensed capacity for a Capacity Tiers license is in full TB amounts, with a minimum of 1 TB. You calculate the licensed capacity by multiplying the amount of usable space by the overhead factor. The overhead factor differs between a single-node and multi-node (HA-pair based) clusters:

  • Overhead factor for single-node clusters is 1.13

  • Overhead factor for multi-node clusters is 2.67

Calculate the licensed capacity based on the usable space to ensure you have enough for your deployment.

Per node in a HA pair:

  • 149 TB (400 / 2.67)

Per HA pair in a multi-node cluster:

  • Two-node: 298 TB (2 x 149)

  • Four-node: 596 TB (4 x 149)

  • Six-node: 894 TB (6 x 149)

  • Eight-node: 1,192 TB (8 x 149)

  • Ten-node: 1,490 TB (10 x 149)

  • Twelve-node: 1,788 TB (12 x 149)
