SAN enhancements
- Support for iSCSI Endpoint Isolation

Storage resource management enhancements
- Support for storage tiers by using FabricPool

Storage efficiency enhancements
- Storage efficiency visualization changes in the CLI

Highlight 1: Aggregate Inline Deduplication

ONTAP 9.2 Feature Support:
- AFF systems only (enabled by default)
- Inline only
- Adaptive compression
- Thin provisioned volumes
- FlexGroup
- MCC
- FabricPool (Flash tier only)

Minimal Performance Impact:
- Overall impact with all efficiency technologies (inline compression, inline dedupe and inline zero-block elimination) < 10%

Opportunistic in nature:
- Preference to maximize latency and throughput.

Highlight 2: QoS now with Minimum Policies

QoS Min delivers:
- Dedicated IOPS Performance
- Enables Service Classes
- Applicable to Vols & LUNs
- Up to 12’000 objects/cluster
- One object per Policy Group
- AFF & SAN only (in 9.2)


Highlight 3: FabricPool

Saving the best for last ... FabricPool is arguably the most exciting new feature in ONTAP 9.2.

Note: The Performance Tier needs to be on flash (i.e. SSD aggregates only). Check with NetApp for supported platforms.

FabricPool Features Support:
- Data Protection (Snapmirror and SnapVault)
- Storage Efficiencies (inline dedupe, inline compression, compaction*, aggregate inline dedupe*)
- Encryption (NVE and NSE)
*supported on performance tier

FabricPool use case #1: Make room for active workloads on Primary storage

Image: FabricPool use case 1: Putting snapshot data in the cloud.
FabricPool use case #2: Shrink your secondary storage footprint

Image: FabricPool use case 2: Expand the capacity of secondary cluster by automatically tiering data to the cloud.
FabricPool use case #3: Volume archive using “vol move” in primary cluster

Image: FabricPool use case 3: “Vol move” off Production HA-pair aggregate to Archive HA-pair aggregate and tier to the cloud.
