Adapting the size of the SES Evolution server according to the number of agents

The table below gives an estimate of the lowest hardware requirements that your SES Evolution environment needs in relation to the number of agents installed. All server components can be installed on the same machine up to 5,000 agents. If you have more than 5,000 agents, you are advised to dispatch components on several machines.

Agent handlers can support up to 30,000 agents.

SSD hard disks are recommended in particular to optimize performance and response time.

IMPORTANT
RAM quota refers to the amount of memory that you must allocate to the SQL Server so that it does not use up all the memory on the server. This value can be configured in SQL Server Management Studio after the databases have been installed. Refer to the RAM column in the table below.
