Active Directory Caching
The
uses a Local AD Cache in an effort to enhance system performance and survivability.
Performance is enhanced by eliminating the need to communicate with and query the Active Directory server for each and every call. This improves the performance of the AD server, and has the added benefit of increasing call speeds and relieving load on the network.
Survivability
In the event of a loss of communication with the Active Directory, whether through a loss of network connectivity or an AD server error, the
is still able to perform call routing tasks based on the Local AD Cache.

If the is rebooted during an Active Directory Server outage, it will use its local AD cache for call routing purposes (post power up) if:- SBC 1000: an external USB storage drive is attached to the SBC 1000 main board. Without it, the local AD cache is purged between system reboots (and upgrades). In order to achieve a high level of resiliency, we recommend attaching an external USB drive to your SBC 1000 unit.
- SBC 2000: Unlike the SBC 1000, the SBC 2000 model has built-in storage with reserved space for the Local AD cache to overcome this situation. No external storage is necessary.
