Chapter 6: Capacity and Deployment Planning
The single-server topology is a useful deployment for evaluating Excel Services. It is the cheapest way to
get Excel Services deployed and for discovering the many features offered by Excel Services.
A single-server topology may also be sufficient to satisfy the needs of an Excel Services production
deployment. This type of deployment is best suited for a work group or business unit. Because
this deployment uses SQL Server Express, the database associated with this deployment is limited
to a maximum size of 4GB.
Small Farm Topology
The small server farm topology typically consists of two computers. The database server is used to host SQL
Server 2005 (or SQL Server 2000), along with the configuration and content databases. A single front-end
server is configured as both the web server and the application server. For Excel Services, this means the
front-end server contains the Excel Services WFE components, and the application server contains the
ECS components. The WFE server may also support other MOSS services, such as search and indexing.
Figure 6-2 shows a small server farm topology.
As mentioned previously, a single-server topology can be used in a production environment, but the
small farm is considered the entry-level production topology. This type of deployment is best suited for
a workgroup or business unit. One immediate advantage to this topology over the single-server
topology is that the 4GB size limit of the configuration and content database is no longer present because the
small farm is using SQL Server. The small farm deployment allows servers to be added (or removed),
which keeps your options open should you ever want to perform actions such as increase the capacity
of the farm or take a server offline.
