Are There Quota Restrictions in UCS?

UCS Quotas

Quotas put limits on the quantity or capacity of resources available to users. UCS allows you to set quotas for third-party clusters and cluster groups.

  • Third-party cluster quota: the maximum number of third-party clusters that can be connected to UCS, excluding the number of CCE clusters.
  • Cluster group quota: the maximum number of cluster groups for a user, excluding the default cluster group automatically created by UCS.

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.
