SQL analysis and report services.

NOTE: If Dell SupportAssist is installed along with OpenManage Essentials, you require 2 GB RAM and 2 cores in

addition to the minimum requirements described in the above table. If you are using SQL Server Standard or

Enterprise Editions, the maximum SQL Server memory must be configured within SQL Server to prevent it from
