Quotas and limits in Compute Cloud
Compute Cloud has the following limits:
- Quotas are organizational restrictions that can be changed by technical support.
- Limits are technical limitations due to Yandex Cloud architectural features. You cannot change the limits.
If you need more resources, you can increase quotas in one of the following ways:
- Generate a request for a quota increase. You must have the
quota-manager.requestOperatorrole or higher, such aseditororadmin. - Contact technical support and tell us which quotas you want increased and by how much.

2 Including the boot disk.
3 At startup, you can connect no more than 14 devices to a VM, including the boot disk and network card. You should connect other devices when your VM is already running. Please note that if you restart a VM with more than 14 devices connected, it will not be able to boot.

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 For maximum IOPS, we recommend keeping your read and write operations close to the disk block size (4 KB by default).
5 For maximum bandwidth, we recommend 4 MB reads and writes.
Limits of disk snapshot schedules
| Type of limit | Value |
|---|---|
| Number of disks added to a schedule | 1,000 |
| Number of schedules a disk is added to | 1,000 |
Other limits
| Type of limit | Value |
|---|---|
| Time to complete processes when stopping a VM6 | 30 seconds |
6 When a VM stops, the hypervisor sends a shutdown signal to the VM operating system. The OS needs to terminate the current processes nice and easy within the next 30 seconds to avoid data loss. After this time elapses, the VM process is forced to stop.
