What's new in ONTAP 9.18.1 for ASA r2 systems

Contributors netapp-aherbin

Learn about the new capabilities available in ONTAP 9.18.1 for ASA r2 systems.

Data protection

Update Description

Increased support for SnapMirror active sync configurations

Suppport for SnapMirror active sync is increased from two-node clusters to four-node clusters.

Networking

Update Description

IPsec hardware offload IPv6 support

IPsec hardware offload support is extended to IPv6.

OpenSSL PQC algorithms

ONTAP supports postquantum computing cryptographic algorithms for SSL. These algorithms provide additional protection against potential future quantum computing attacks, and are available when SSL FIPS mode is disabled.

SAN data migration

Update Description

Support for storage VM migration

You can non-disruptively migrate a storage virtual machine (VM) from an ASA cluster to an ASA r2 cluster. This enables block workloads to move to ASA r2 systems while preserving data integrity and ensuring no application impact. The migration process is designed to maintain existing host mappings and LUN configurations, reducing operational effort and risk during migration.

Storage efficiency

Update Description

Support for NVMe copy offload

NVMe copy offload enables an NVMe host to offload copy operations from its CPU to the CPU of the ONTAP storage controller. The host can copy data from one NVMe namespace to another while reserving its CPU resources for application workloads.

Support for modification of snapshot reserve and automatic snapshot deletion

You can modify snapshot reserve and enable automatic snapshot deletion to limit the amount of space used for snapshots in your ASA r2 storage units. When snapshot reserve is set with automatic snapshot deletion, older snapshots are automatically deleted when space used by snapshots exceeds the snapshot reserve. This prevents application disruptions by not allowing snapshots to consume space in your storage unit intended for user data.
