Quotas and limits in Compute Cloud
Compute Cloud has the following limits:
- Quotas are organizational restrictions that can be changed by technical support on request.
- Limits are technical limitations due to Nebius AI architectural features. The limits cannot be changed.
If you need more resources, generate a request for a quota increaseeditors

Read and write operations utilize the same disk resource. The more read operations you do, the fewer write operations you can do, and vice versa. For more information, see Read and write operations.
4 To achieve maximum IOPS, we recommend performing read and write operations whose size is close to that of the disk block (4 KB by default).
5 To achieve the maximum possible bandwidth, we recommend performing 4 MB reads and writes.
