The
installation of the Exchange Server 2010 CAS role is a straightforward
task. This section covers the installation and configuration of a basic
system to illustrate the concepts.
The installation of the CAS
role assumes that Exchange Server 2010 is already installed on the
target server.
Memory and CPU maximum recommendations for the CAS role are shown in Table 1. Beyond these capacities, there will be diminishing returns. These are based on the Exchange Server product group testing.
Table 1. CAS Role Server Resources
| Configuration | Processor | Memory | Storage |
|---|
| Minimum | 2 cores | 2GB | 2GB |
| Maximum | 12 cores | 16GB | N/A |
| Recommended | 8 cores | 2GB per core | 32GB |
Installation of the
CAS role modifies the base installation of Exchange Server 2010 and is
done in what is termed Exchange Maintenance mode. The procedures in this
section step through the build of a basic Exchange Server 2010 CAS
system.
