true by changing the settings under Audio Conferencing to ensure that video conferencing load was
simulated by the tool.
In addition to performance analysis, Dell conducted a thorough investigation of other components in the
architecture, including the Sonus SBC 1000 SBC/gateway. The SBC 1000 was validated for SIP trunking
and T1/E1 connectivity, i.e. both as an SBC and as a gateway. In addition, the failover capability of the
device in an active-active pair was also verified. In an active-active pair, the SBC 1000 provides the needed
availability in case one unit was to fail.
Next, failover functionality of the Front End to the backup registrar pool was also verified. Failover to the
backup registrar is relatively simple and can be accomplished by running the following commands:
Invoke-CsManagementServerFailover -BackupSqlServerFqdn <backupregistrarfqdn>
BackupSqlInstanceName RTC –Force
Invoke-CsPoolFailOver –PoolFqdn <poolfqdn> –Disastermode –Verbose
It should be noted that the user contact lists and presence are not available until the IT administrator takes
these manual steps in the event that failover is needed. However, ongoing instant messages and
audio/video/web conferences continue even upon failure of the primary Front End.
Lastly, client devices were validated for both internal and external connectivity. Devices used included Dell
Latitude 10 tablets and Polycom CX600 phones. The Latitude 10 tablets provide audio/video/web
conferencing using the Lync app available from the Microsoft store.
