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 deployment needs
Example 1: In your planning you determine that you require the capacity for 125
Example 2: You determine that you require 20 high definition audio (G.722)
Example 3: You determine that you require the capacity for 150 concurrent
Example 4: You determine that you require 600 configured IM sessions. The SA-

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.
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.
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.
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.
