Bandwidth The bandwidth varies with capacity. The maximum bandwidth is 1.2 GB/s. The following examples show the capacity range and the corresponding bandwidth:
  • [100 GiB, 500 GiB): 150 MB/s
  • [500 GiB, 2 TiB): 300 MB/s
  • [2 TiB, 4 TiB): 600 MB/s
  • [4 TiB, 8 TiB): 900 MB/s
  • [8 TiB, 256 TiB): 1,200 MB/s

IOPS The input/output operations per second (IOPS) varies with capacity. You can use the following formula to calculate the read and write IOPS:
  • Read IOPS = 7,000 + 30 × Capacity (GiB). The maximum IOPS is 200,000.
  • Write IOPS = 3,500 + 15 × Capacity (GiB). The maximum IOPS is 100,000.
The IOPS varies with capacity. You can use the following formula to calculate the read and write IOPS:
  • Read IOPS = 5,000 + 50 × Capacity (GiB). The maximum IOPS is 200,000.
  • Write IOPS = 2,500 + 25 × Capacity (GiB). The maximum IOPS is 100,000.
Latency 1.2 ms 0.3 ms
Maximum capacity 256 TiB 256 TiB
Minimum capacity 100 GiB 100 GiB
Scaling step size 1 GiB 1 GiB
Scaling method Manual scaling Manual scaling

Scenarios High-performance web services and CI/CD development and testing environments.
Note
  • The advanced edition of Extreme NAS file systems is unavailable in some zones due to the limits of infrastructure. In this case, select the standard edition instead.
  • We recommend that you create an Extreme NAS file system in the same zone as your business.
  • After an Extreme NAS file system is created, its type cannot be modified.
