General Recommendations
The following recommendations can help the customer to select the servers to buy:
 Buy a server from a reputable manufacturer to host ShoreTel’s software. We advise against using
servers from clone manufacturers for business-critical applications.
 Be sure each server that runs ShoreTel server software has enough processing capacity to
support the planned telephony workload. ShoreTel servers perform call control (call setup and
tear-down functions) and provide the services of voicemail, automated attendant, workgroup
management, configuration databases, and more. The headquarters server also hosts the system
configuration tool, Web pages for the user-interface and conferencing; and maintains call records
and the history database.
 Do not use a ShoreTel server as a domain controller.
Requirements for ShoreTel Enterprise Systems
This section provides information necessary to provision servers on which to install ShoreTel
Enterprise software.
The ShoreTel Enterprise Edition system is scalable. In the spirit of economy and efficiency, ShoreTel
Enterprise customers provide their own server hardware allowing them to build the optimum phone
system for their environment. To assist in creating the optimum system, ShoreTel has defined a tier
system based on the number of users the system is to support and set minimum server requirements
for each tier. The tiers ShoreTel defines are:
 Branch office bundle (functions only as a DVS server) or an SBE server the customer has
upgraded to Enterprise Edition—both support up to 100 users.
 Small servers that support up to 500 users.
 Medium servers that support up to 2,500 users.
 Large servers that support up to 10,000 users.
 Very large servers that support up to 20,000 users.
Note
If a planned upgrade to the current release means that the current server cannot adequately support
the new release of ShoreTel software, upgrade the server to a model with greater capacity before
doing the server software upgrade.
Note
SBE systems upgraded to Enterprise support the same capacities as the small Enterprise system.
