Quotas and limits in Managed Service for Redis
Written by
Managed Service for Redis has the following limits:
- Quotas are organizational restrictions that can be changed by technical support on request.
- Limits are technical limitations due to Yandex Cloud architectural features. The limits cannot be changed.
If you need more resources, increase the quotas in one of the following ways:
- Generate a request for a quota increase. You must have the
quota-manager.requestOperatorrole or higher (editororadmin). - Contact support and tell us which quotas you need to increase and by how much.
Quotas
| Type of limit | Value |
|---|---|
| Number of clusters per cloud | 16 |
| Total number of processor cores for all the database hosts in a cloud | 64 |
| Total virtual memory for all DBs per cloud | 512 GB |
| Total storage capacity for all clusters per cloud | 4096 GB |
Limits
| Type of limit | Minimum value | Maximum value |
