Performance considerations for large volumes
Throughput ceilings for the three Azure NetApp Files performance tiers (Standard, Premium, and Ultra) of large volumes are based on the existing 100-TiB maximum capacity targets. You can increase to 1 PiB with the throughput ceiling per the following table:
| Capacity | Linear performance scaling per TiB up to maximum allowed capacity tier throughput (large volume) | |||
|---|---|---|---|---|
| Capacity tier | Minimum volume size (TiB) |
Maximum volume size (TiB) | Minimum throughput for capacity tier (MiB/s) | Maximum throughput for capacity tier (MiB/s) |
| Standard (16 MiB/s per TiB) | 50 | 1,024 | 800 | 12,800 |
| Premium (64 MiB/s per TiB) | 50 | 1,024 | 3,200 | 12,800 |
| Ultra (128 MiB/s per TiB) | 50 | 1,024 | 6,400 | 12,800 |

64-bit file IDs
Whereas regular volumes use 32-bit file IDs, large volumes employ 64-bit file IDs. File IDs are unique identifiers that allow Azure NetApp Files to keep track of files in the file system. 64-bit IDs are utilized to increase the number of files allowed in a single volume, enabling a large volume able to hold more files than a regular volume.
