Large file support co-exists with the full array of other OneFS data services. The one caveat is SyncIQ replication, which has prerequisites, as described in SyncIQ requirements for large file replication. The following table describes the integration, influence, and compatibility between inline data reduction and the various OneFS data services.
OneFS feature | Detail |
SyncIQ | |
NDMP Backup | Large files are backed up the same for any OneFS file size. OneFS NDMP backup data is not compressed unless compression is provided by the backup vendor’s DMA software. However, compression is often provided natively by the backup tape or VTL device. Warning: Restoring an NDMP backup containing any file larger than 4 TiB onto a cluster that does not support 16 TiB large files will fail. |
SnapshotIQ | Large files are supported by SnapshotIQ read-only snapshots and writable snapshots. |
SmartLock | Large files up to 16 TiB are fully compatible with SmartLock, the OneFS data retention and compliance product. Large file supports give additional flexibility to OneFS immutable archives and write once, read many (or WORM) protected datasets. |
SED Encryption | Clusters employing encryption with SED drives are fully compatible with large files. |
SmartQuotas | OneFS SmartQuotas is one of the principal methods for inline data reduction efficiency reporting. From the quota side, large files are reported on and acted on as expected in configured quota policies. |
SmartPools | All node pools on a cluster must confirm to the prerequisites before large file support can be enabled. As such, large files and SmartPools tiering are fully compatible with each other. |
CloudPools | CloudPools cloud tiering fully supports large files. When tiered, a large file’s data is moved to a cloud provider, and stub file reference is created locally. |
Non-disruptive Upgrade | Large file support was introduced in OneFS 8.2.2. Non-disruptive upgrades to a later release are fully supported. |
File Clones | File cloning places data in shadow stores and fully supports large files. |
In-line Data Reduction | In-line data reduction and large file support are fully compatible on appropriately sized compression node pools. |
SmartDedupe | SmartDedupe post process deduplication and large file support are fully compatible with each other. |
Small File Storage Efficiency (SFSE) | Large files co-exist with small files containerized with OneFS SFSE. |
Job Engine | The job engine and restriping jobs all fully support large files. The FSA job in OneFS 8.2.2 and later includes a bucket for reporting on files larger than 10 TiB. |
DataIQ and InsightIQ | DataIQ and InsightIQ both support and accurately report OneFS large files as expected. |
Note: Except for the job engine, file clones, and non-disruptive upgrade (NDU), each of the services listed in Table 5 require a product license or specific hardware. Licensed data services are not enabled, configured, and active by default on a cluster.
