SA-100 Planning, Installation and Administration Guide Chapter 2: Planning and System Design
2.2.1 Determining the Number of SA-100s to Deploy
Among the factors to consider in determining how many SA-100 to deploy are the
capabilities of the SA-100. Table 2-1 provides information about the maximum number of
participants an SA-100 can support by conference type.
The examples below show how you can use the information in the table to determine your
Example 1: In your planning you determine that you require the capacity for 125
concurrent, standard audio (G.711) conferences. To determine how many
SA-100 your system requires, divide the number of conferences you
determine that you require by the maximum number of conferences the
SA-100 supports, i.e. 125 ÷ 50 = 2.5. To satisfy the requirement for your
network, you would install three SA-100s.
Example 2: You determine that you require 20 high definition audio (G.722)
conferences and 90 standard audio conferences. An SA-100 can support no
more than 15 HD conferences with up to 35 standard conferences
simultaneously. To determine how many SA-100s you need, assign the first
15 HD conferences and the first 35 standard conferences to one SA-100.
That leaves 5 HD conferences and 55 standard conferences to be
supported. You can combine the remaining 5HD with 45 standard
conferences to achieve the capacity for a second SA-100. That leaves 10
standard conferences which can be supported by a third SA-100.
Consequently, you will need three SA-100 to satisfy this scenario.
Example 3: You determine that you require the capacity for 150 concurrent HTTPS
Web conference sessions. The SA-100 supports up to 30 HTTPS Web
conferences simultaneously. To determine how many SA-100s you need,
divide the total number of HTTPS conferences by the maximum number
of HTTPS conferences the SA-100 supports, i.e. 150 ÷ 30 = 5. You need five
SA-100 to satisfy the requirement in this scenario.
Example 4: You determine that you require 600 configured IM sessions. The SA-100
supports up to 500 IM sessions simultaneously. To determine how many
SA-100 you need to satisfy this requirement, divide the total number of IM
sessions by the number of simultaneous IM sessions the SA-100 supports,
i.e. 600 ÷ 500 = 1. You need two SA-100s to satisfy this requirement.
2.2.2 Considering System Topology
The topology in which your ShoreTel system is install can be a factor in determining how
you deploy the SA-100. For ShoreTel systems installed over multiple sites (a site is an area
managed by a ShoreTel server), whether those sites are in the same building or spread
across diverse geographical regions, it may be more effective and efficient to install SA-100
units at specific sites. For example, if your experience includes inconsistent WAN
