Considerations for sizing an ONTAP Select Capacity Pools license

The licensed capacity for a Capacity Pool license is in full TiB amounts, with a minimum of 2 TiB. 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

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

Description Single-node HA pair or mix of HA and single-node

Usable space

10 TiB per single-node cluster

20 TiB for HA pair

Licensed space

23 TiB

(20 x 1.13 = 22.6, round up to next full TiB)

54 TiB

(20 x 2.67 = 53.4, round up to next full TiB)

Maximum usable space per node

Note: The maximum managed space per node or HA pair is 400 TiB

353 TiB

(400 / 1.13)

Per single-node cluster:

74 TiB [(400 / 2) / 2.67]

Per HA pair cluster:
