ShoreTel 14.2 Planning and Installation Guide 37
To select a server for your new system deployment, first consult the sizing table and determine the tier
of the server needed using the system and per server specifications. Then match that size (small,
medium, large or very large) to the server requirements shown in Table 10.
When deploying servers for medium or large systems, be aware that you must select an operating
system that supports expanded memory, such as the Enterprise Editions of Microsoft Windows 2003
server or Microsoft Windows 2008 Server.

Note
Use the hardware specifications to size servers running ShoreTel Headquarters server software and
ShoreTel Distributed Voice Services software. For example, consider a 2 location system with 2,000
users and 20,000 BHCC. A Headquarters server is located at the main site and a Distributed Voice
Services server is located at the remote site. Each of the servers handle 2,000 BHCC. In this case,
both servers should be provisioned with hardware that meets the medium tier of hardware
requirements because the system capacity and both server capacities fall within this tier.
