Quotas
Limits

The reserved instance pool feature is at the Preview stage.

Compute Cloud has the following limitations:

Quotas are organizational constraints that can be changed by contacting technical support.
Limits are technical constraints of the Yandex Cloud architecture. You cannot change the limits.

If you need more resources, you can increase your quotas in one of the following ways:

Make a request to increase your quotas.
Contact support and specify which quotas you want increased and by how much.

To have your request processed, you must have the quota-manager.requestOperator role or higher, e.g., editor or admin.

You can manage your quotas with Cloud Quota Manager.

⁴ 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.

Warning

To guarantee the operability and performance of VMs with large numbers of disk devices and network interfaces, such numbers of devices and interfaces must be supported not by the VM hardware generation alone but by the OS as well, plus provided with enough vCPUs and RAM.

VM limits related to disks

The values listed below are VM side limitations. They scale with the number of vCPUs: the row value is multiplied by the number of vCPUs to set the upper boundary of the total load on all disks attached to the VM. For example, for a VM with 4 vCPUs and a network SSD, the total maximum IOPS cannot exceed 4 × 3,500 = 14,000.

The actual performance of an individual disk is also capped by its own limits. The final value is determined as the minimum of the two: the VM limit and the disk limit.

Note

IOPS and bandwidth limits of an individual disk depend on the number of allocation units. For more information, see Disk and file storage performance.

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.

⁵ For maximum IOPS, we recommend keeping your read and write operations close to the disk block size (4 KB by default).

⁶ 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

Other limits

Type of limit	Value
Time to complete processes when stopping a VM⁷	30 seconds

⁷ When a VM stops, the hypervisor sends a shutdown signal to the VM operating system. The OS has 30 seconds to gracefully terminate all running processes to avoid data loss. After this time elapses, the VM will be forcibly terminated.
