+A quota is a credit limit, not a capacity guarantee. If you have large-scale capacity needs, please contact Azure support.

+Also note that quotas are not guaranteed values. Quotas can vary based on changes from the Batch service or a user request to change a quota value.

 ### Cores quotas in user subscription mode
 
 If you created a Batch account with pool allocation mode set to **user subscription**, quotas are applied differently. In this mode, Batch VMs and other resources are created directly in your subscription when a pool is created. The Azure Batch cores quotas do not apply to an account created in this mode. Instead, the quotas in your subscription for regional compute cores and other resources are applied. Learn more about these quotas in [Azure subscription and service limits, quotas, and constraints](../azure-subscription-service-limits.md).
 
 ## Pool size limits
 
+Pool size limits are set by the Batch service. Unlike [resource quotas](#resource-quotas), these values cannot be changed. Only pools with inter-node communication and custom images have restrictions different from the standard quota.
