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.

9.2RC1 Available
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)

Unique value add
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

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

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