| [Data Warehouse Units (DWU)](what-is-a-data-warehouse-unit-dwu-cdwu.md) |Default DTU per server |54,000<br></br>By default, each SQL server (for example, myserver.database.windows.net) has a DTU Quota of 54,000, which allows up to DW6000c. This quota is simply a safety limit. You can increase your quota by [creating a support ticket](sql-data-warehouse-get-started-create-support-ticket.md) and selecting *Quota* as the request type. To calculate your DTU needs, multiply the 7.5 by the total DWU needed, or multiply 9 by the total cDWU needed. For example:<br></br>DW6000 x 7.5 = 45,000 DTUs<br></br>DW7500c x 9 = 67,500 DTUs.<br></br>You can view your current DTU consumption from the SQL server option in the portal. Both paused and unpaused databases count toward the DTU quota. |

| Database connection |Maximum Concurrent open sessions |1024<br/><br/>The number of concurrent open sessions will vary based on the selected DWU. DWU1000c and above support a maximum of 1024 open sessions. DWU500c and below, support a maximum concurrent open session limit of 512. Note, there are limits on the number of queries that can execute concurrently. When the concurrency limit is exceeded, the request goes into an internal queue where it waits to be processed. |

| [Workload management](resource-classes-for-workload-management.md) |Maximum concurrent queries |128<br/><br/> A maximum of 128 concurrent queries will execute and remaining queries will be queued.<br/><br/>The number of concurrent queries can decrease when users are assigned to higher resource classes or when the [data warehouse unit](memory-concurrency-limits.md) setting is lowered. Some queries, like DMV queries, are always allowed to run and do not impact the concurrent query limit. For more information on concurrent query execution, see the [concurrency maximums](memory-concurrency-limits.md) article. |
