The maximum number of ENIs that can be bound to a CVM and that of private IPs that can be bound to each ENI vary greatly with CPU and memory configurations. The limits are shown in the following table.
| CVM Configuration | Max. Number of ENIs | Max. Number of IPs Bound to Each ENI |
|---|---|---|
| CPU: 1-core Memory: 1 GB | 2 | 2 |
| CPU: 1-core Memory: >1 GB | 2 | 6 |
| CPU: 2-core | 2 | 10 |
| CPU: 4-core Memory: ≤ 16G | 4 | 10 |
| CPU: 4-core Memory: >16 GB | 4 | 20 |
| CPU: 8-12 core | 6 | 20 |
| CPU: >12-core | 8 | 30 |
