In a Multi-ESM Server deployment you can deploy multiple
ESM Servers to support the agents in your organization. Each ESM
Server supports up to 30,000 agents for a total number of 150,000
agents per database. While you can deploy as many ESM Servers as
you want, you cannot exceed the total number of supported agents
for the database.
Before installing ESM Server software, make sure that the server
meets the following prerequisites:
ESM Server and ESM Console running
the same version.
ESM Server hostname of 15 or fewer characters
Clock that is synchronized to the time of other ESM components (console
and database) using standard enterprise networking means such as Windows
Time Service (WTS).
Ensure that the round-trip communication time between the
ESM Server and the database is less than 80 ms.
.NET Framework 4.5.1 Full or later
SSL certificate from a trusted certificate authority (CA)
with server authentication and client authentication (
Allow communication on the TCP port from clients to server
(the default is port 2125)
For automated content updates, enable SSL/TLS 1.2 communication between
the ESM Server and the followings sites on port 443:
Forensic folder with BITS enabled
Internet Information Services (IIS) 7.0 or above with ASP.NET
and Static Content Compressions components
Communication between the ESM Server and the agents is based
on Windows Communication Foundation (WCF) client with a TLS/SSL
version which is dependent on the version of the Traps agent and
the operating system.
Traps 4.0 and 4.1 releases on
Windows XP, Windows Vista, Windows Server 2003, and Windows Server
Traps 4.0 and 4.1 releases on all other operating systems—TLS/SSL
