Are There Quota Restrictions in UCS?

UCS Quotas

Quotas can limit the number or amount of resources available to users. UCS has quota limits on clusters, fleets, permissions, cluster federations, and CIA instances.

• Cluster quota: specifies the maximum number of clusters connected to UCS. This item applies to both Huawei Cloud clusters and attached clusters.
• Fleet quota: specifies the maximum number of fleets owned by a user.
• Permission quota: specifies the maximum number of permission policies that a user can create on the Permissions page.
• Cluster federation quota: specifies the maximum number of cluster federations that a user can enable.
• CIA instance quota: specifies the maximum number of CIA instances that a user can create.

For other cloud services you may also use when running UCS, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Virtual Private Cloud (VPC), Elastic Load Balance, SoftWare Repository for Container (SWR), and Domain Name Service (DNS), their quotas are independent of those of UCS and are managed by themselves. For details, see Quotas.
