NetApp Cloud Tiering
The NetApp Cloud Tiering solution is called FabricPool.
FabricPool is a NetApp tiering technology that enables automated tiering of data from an all-flash appliance to low-cost object storage tiers either on or off premises. This technology is a form of storage pools which are collections of storage volumes exported to a shared storage environment.
Cloud tiering and data tiering (or data archiving) can deliver significant data storage cost savings as part of a cloud storage strategy by offloading unused cold data to more cost-efficient cloud storage solutions. The approach you take to NetApp tiering can either create an easy path to the cloud with native access and full use of data in the cloud or it can create costly cloud egress and lock-in.
Here is some background on storage tiering.
- Storage array vendors have historically done delivered minimal insight into the data stored on them.
- As unstructured data growth has created more cost and complexities for enterprises, storage vendors have introduced new solutions to externally tier data to the cloud.
- NetApp FabricPool for NetApp cloud tiering and Dell EMC Isilon CloudPools for Isilon cloud tiering, may reduce the cost of super-fast, expensive flash-based storage by adding lower-cost choice in cloud storage, but there are trade-offs.
Blocks vs. Files
Storage-based cloud tiering provides limited data analytics and limited policies for data tiering. File storage arrays use an efficient block-based storage system to store files. Each file is represented by a set of equally sized blocks, which grow as the file grows. To reduce the cost of the storage arrays, vendors provide multiple tiers of storage, from fast flash storage to slower, lower cost SAS drives and SATA drives.
Commonly, the storage tiering system places file metadata and the frequently accessed blocks (from any file) in the highest tier and less accessed blocks stored on lower, less expensive tiers. By applying their tiering system, designed to work efficiently with internal storage tiers, to tier data to the cloud, it tiers cold blocks rather than files to the cloud. Metadata resides on the storage vendor filesystem and all data access needs to occur through the storage filesystem. Storage tiering solutions are good for tiering snapshots to the cloud, they result in unnecessary costs and lock-in for tiering files.
The Komprise hybrid tiering approach addresses these challenges by moving the entire file, so you don’t experience rehydration penalties when you need to move the data again. You can adopt new storage anytime with no penalties, due to the standards-based approach. Users and applications can access the tiered files from the original location with no disruption, thanks to Komprise Transparent Move Technology. File tiering moves unused cold data from the active footprint so that cold data is stored on low-cost, resilient solutions such as object storage which can be 30 times cheaper than file storage.
Komprise hybrid tiering is both a complement and an alternative to built-in tiering capabilities from data storage vendors, delivering more benefits and ROI such as:
1.Reduce your ransomware attack surface.
Unstructured file data is highly vulnerable to ransomware attacks due to its vast surface area and widespread access across enterprise users and applications. Komprise’s hybrid tiering strategy helps mitigate this risk by moving cold data to an object-locked destination, reducing the attack surface by up to 70% while also lowering storage costs. Additionally, features like versioning and tamperproof snapshots provide further protection by ensuring an intact copy of data is available for restoration even in the event of an attack.
2. Avoid rehydration when refreshing your storage.
Enterprise data storage systems require frequent refreshes, leading to high costs when switching vendors due to data rehydration. Traditional tiering solutions, like NetApp FabricPool, force enterprises to buy more storage just to migrate off their existing platform, increasing expenses and complexity. Komprise’s hybrid tiering eliminates this issue by offering storage-agnostic, file-based tiering that preserves file fidelity and avoids costly rehydration during migrations.
3. Provide flexible data management polices while maintaining transparent access.
Storage-based data tiering is limited by vendor-specific constraints, such as a fixed policy that prevents gradual data movement to lower-cost storage over time. In contrast, Komprise hybrid tiering offers a flexible, policy-driven approach that works across heterogeneous storage environments without disrupting users or applications, thanks to Transparent Move Technology (TMT™). For example, a higher education IT team using NetApp and StorageGrid can seamlessly tier older data to Wasabi with Komprise, maximizing cost savings and efficiency.
4. Ensure innovation and choice with cloud native data access.
Cloud hyperscalers offer rapid innovation, making it essential to fully use cloud storage tiers for cost efficiency, such as Amazon FSx versus S3 Glacier Instant Retrieval. Komprise hybrid tiering allows for seamless data movement to lower-cost cloud storage while maintaining native access, allowing users to access data directly in the cloud and apply cloud services such as AI to the data. In contrast, traditional storage-based tiering moves data in blocks within proprietary systems, limiting its usability in the cloud beyond simple archiving.

5. Ensure your unstructured data is ready for AI.
Most storage-tiering solutions are proprietary and restrict seamless cloud access, whereas Komprise hybrid tiering ensures data remains open and accessible to any AI service. This open approach ensure that data is not locked away in proprietary format. limiting its accessibility and use for AI. As well, AI readiness is a top challenge in unstructured data management, making it crucial to choose a tiering solution that supports automated AI data workflows with proper AI data governance, across all data regardless of where it is stored.
