For ShoreTel 11.1 Server Hardware requirements and specifications, refer to Chapter 2 -
System Overview in this guide and the ShoreTel 11.1 - ShoreWare Release Notes.

Approximately 1600 MB of hard disk space is used on the server for program software.
Additional hard disk space is used for voice mail, call detail records (main server only), and
10.4.1 Voice Mail
Each user’s voice mail messages are stored on his or her respective server. The hard disk
space used on each server for voice mail varies depending on the number of users, the
number of messages per user, and the duration of each message.
You need approximately 30 MB of hard disk space per hour for voice mail storage.
Table 10-3 provides some conservative guidelines to estimate the amount of hard disk
space used for voice mail, assuming each user has 15 one-minute voice messages.
10.4.2 Call Detail Records
For each call on the system, call detail records are generated on the main server. The hard
disk space used on the server for call detail records varies depending on the call load on the
system. The amount of hard disk space for a typical system is shown in Table 10-4.
