Platforms |
The following NetApp ASA r2 systems are supported beginning in ONTAP 9.16.1. These platforms deliver a unified hardware and software solution that creates a simplified experience specific to the needs of SAN-only customers.

Data protection
| Update | Description |
|---|---|
When you switch from the ONTAP onboard key manager to an external key manager at the cluster level, you can use the ONTAP command line interface (CLI) to easily migrate the encryption keys from one key manager to the other. |
|
Hierarchical consistency groups allow you to create a parent consistency group that contains multiple child consistency groups. This simplifies data protection and management for complex data structures. |
Protocol support
| Update | Description |
|---|---|
NVMe/FC and NVMe/TCP now support symmetric active-active architecture for multipathing so that all paths between the hosts and storage are active/optimized. |
Storage efficiency
| Update | Description |
|---|---|
Support for automatic rebalancing of storage units |
ONTAP will automatically rebalance storage units across your storage availability zones for optimal performance and capacity utilization. |
NVMe space deallocation enabled by default |
Space deallocation (also called “hole punching” and “unmap”) is enabled for NVMe namespaces by default. Space deallocation allows a host to deallocate unused blocks from namespaces to reclaim space. This greatly improves overall storage efficiency, especially with file systems that have data high turnover. |
