@Kalidas Yerravarapu Thank you for posting your query on Microsoft Q&A and for using Azure services.
In my understanding you are looking to know the size of Azure Synapse dedicated SQL pool.
The size of a dedicated SQL pool (formerly SQL DW) is determined by Data Warehousing Units (DWU). Read more on What is dedicated SQL pool (formerly SQL DW) in Azure Synapse Analytics?
For furthermore details on how to find performance tiers, Datawarehouse Units, and how to view the current settings of DWU. Please check this Data Warehouse Units (DWUs) for dedicated SQL pool (formerly SQL DW) in Azure Synapse Analytics
Please let me know if this is helpful. If you have any further queries, please feel free to reach out.
