1 Examining a complex ISA Enterprise deployment.
Determining CSS Placement
As previously mentioned, there are several deployment scenarios for the CSS, starting with
simpler, smaller deployments and moving up to larger deployments. These scenarios are
as follows:
. CSS installed on the ISA server itself
. CSS installed on a separate server or servers running other services, such as a
domain controller

. CSS on a dedicated server
. Multiple CSS servers on multiple types of different servers
With CSS, the important thing to remember is that it should be secured and made highly
redundant. In addition, there should be a local CSS replica relatively close to the ISA
arrays themselves.
