Capacity and Hardware Requirements for Headquarters
Servers
Table 31 shows information about system capacity for each tier of the Headquarters servers. The table
shows the number of users, calls, and reports that the server can support for each tier. Table 32 shows
our recommendations for each tier of Headquarters server. Use these tables to determine the needs
for Headquarters servers in the ShoreTel deployment. You can mix servers of different capacities, but
choose the right servers for the telephony environment.

Note
 BHCC (Busy Hour Call Completion) per system is the total number of system calls during the busy
hour including internal and external calls, calls terminated to desk phones, softphones, trunks or
server applications such as voicemail.
 BHCC per server is based on the number of calls actually handled by the server during the busy
hour including workgroup calls in menus and queues, auto-attendant calls and calls to the voicemail
service.
 By default, the ShoreTel report generation tools that run on the server have a lower priority than
other, more critical services. Low-demand report generation should have little or no affect on a
server with adequate performance specifications. If you are a heavy report user or experience any
degradation of voicemail or other server prompts on an underpowered server, you must move up to
the next tier level of servers.
 For very large system deployments (10K to 20K), the number of ShoreTel Communicator for
Windows users is 500. The number of ShoreTel Communicator for Web and mobile users in 1000.
