There are limits for storage objects that you should consider when planning and managing your storage architecture.
Limits are listed in the following sections:
| Limit | Native storage | Storage arrays | Virtual storage (Data ONTAP-v) | Notes |
|---|---|---|---|---|
| Array LUNs Minimum size for root volume |
N/A | Model-dependent | N/A | See the Hardware Universe. |
| Files Maximum size |
16 TB | 16 TB | 16 TB | |
| Files Maximum per volume |
Volume size dependent, up to 2 billion | Volume size dependent, up to 2 billion | Volume size dependent, up to 2 billion | 2 billion = 2 × 10 to the 9th power. |
| FlexCache volumes Maximum per system |
100 | 100 | N/A | |
| FlexClone volumes Hierarchical clone depth |
499 | 499 | 499 | The maximum depth of a nested hierarchy of FlexClone volumes that can be created from a single FlexVol volume. |
| FlexVol volumes Maximum per system |
Model-dependent | Model-dependent | 200 | See the Hardware Universe. |
| FlexVol volumes Minimum size |
20 MB | 20 MB | 20 MB | |
| FlexVol volumes (32-bit) Maximum size |
16 TB | 16 TB | 16 TB | |
| FlexVol volumes (64-bit) Maximum size |
Model-dependent | Model-dependent | 16 TB | See the Hardware Universe. |
| FlexVol root volumes Minimum size |
Model-dependent | Model-dependent | Model-dependent | See the Hardware Universe. |
| LUNs Maximum per controller or HA pair |
|
|
1,024 | |
| LUNs Maximum per volume |
|
|
512 | |
| LUNs Maximum size |
16 TB | 16 TB | 16 TB | |
| Qtrees Maximum per volume |
4,995 | 4,995 | 4,995 | |
| Snapshot copies Maximum per FlexVol volume |
255 | 255 | 255 | The use of certain Data ONTAP capabilities could reduce this limit. For more information, see the Data ONTAP Data Protection Online Backup and Recovery Guide for 7-Mode. |
| Traditional volumes Maximum size |
16 TB | 16 TB | Model-dependent | See the Hardware Universe. |
| Traditional volumes and aggregates Maximum per system |
100 | 100 | 100 | In an HA configuration, this limit applies to each node individually, so the overall limit for the pair is doubled. |
| Limit | Native storage | Storage arrays | Virtual storage (Data ONTAP-v) | Notes |
|---|---|---|---|---|
| Aggregates and traditional volumes (combined) Maximum per system |
100 | 100 | 100 | In an HA configuration, this limit applies to each node individually, so the overall limit for the pair is doubled. |
| Aggregates (32-bit) Maximum size |
16 TB | 16 TB | 16 TB | |
| Aggregates (64-bit) Maximum size |
Model-dependent | Model-dependent | 16 TB | See the Hardware Universe. |
| Aggregates Minimum size |
RAID-DP: 3 disks RAID4: 2 disks |
Model-dependent | N/A | See the Hardware Universe for the minimum aggregate size for RAID0. |
| Aggregates (mirrored) Maximum suggested per system |
64 | 64 | N/A | You can create more than 64 mirrored aggregates on a storage system, but doing so could cause plex synchronization problems after certain types of failures. |
| RAID groups Maximum per aggregate |
150 | 150 | 150 | |
| Traditional volumes Maximum size |
16 TB | 16 TB | 16 TB |
| Limit | Native storage | Storage arrays | Virtual storage (Data ONTAP-v) | Notes |
|---|---|---|---|---|
Maximum per system |
400 | 400 | 400 | |
Maximum per aggregate |
150 | 150 | 150 |
| RAID type | Default size | Maximum size | Minimum size |
|---|---|---|---|
| RAID-DP |
SATA/BSAS/FSAS/MSATA/ATA: 14
FC/SAS: 16 SSD: 23 |
SATA/BSAS/FSAS/MSATA/ATA: 20
FC/SAS: 28 SSD: 28 |
3 |
| RAID4 |
SATA/BSAS/FSAS/MSATA/ATA: 7
FC/SAS/SSD: 8 |
SATA/BSAS/FSAS/MSATA/ATA: 7 FC/SAS/SSD: 14 |
2 |
| RAID0 | 8 | 26 | 1 |
| Limit | Native storage | Storage arrays | Virtual storage (Data ONTAP-v) | Notes |
|---|---|---|---|---|
| Maximum per file or LUN | 32,767 | 32,767 | 32,767 | If you try to create more than 32,767 clones, Data ONTAP automatically creates a new physical copy of the parent file or LUN. This limit might be lower for FlexVol volumes that use deduplication. |
| Maximum total shared data per FlexVol volume | 640 TB | 640 TB | 640 TB |
