Chapter 2 Cisco Unity Concepts

Where Cisco Unity Stores Data

currently supported by DUC for Cisco, see the “Domino Requirements—Message Store” section of System Requirements for Cisco Unity at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

Cisco Unity can service subscribers on multiple Domino servers. You specify one Domino server (the partner Domino server) through which Cisco Unity communicates with the other Domino servers.

Cisco Unity can also service subscribers on Domino clusters. If subscribers are homed on one or more Domino servers in a cluster, every Domino server in the cluster on which there will be Cisco Unity subscribers must have DUC installed.

Exchange

Cisco Unity can store voice messages in supported versions of Exchange. For information on versions of Exchange currently supported for use with Cisco Unity, see the “Exchange Requirements—Message Store” section of System Requirements for Cisco Unity at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

For small Cisco Unity Voice Messaging configurations, Exchange can be installed on the Cisco Unity server, and all Cisco Unity subscribers can have their Exchange mailboxes on the Cisco Unity server. (Exchange can also optionally be installed on a separate server instead of, or in addition to, being installed on the Cisco Unity server.) A Cisco Unity subscriber is someone who has an Exchange mailbox and whose Active Directory account includes Cisco Unity-specific information.

For medium and large Cisco Unity Voice Messaging configurations and for all Unified Messaging configurations, Exchange is installed on one or more separate servers instead of on the Cisco Unity server. For these configurations, subscribers can have their Exchange mailboxes on other Exchange servers.

Cisco Unity can service subscribers on multiple Exchange servers. You specify one Exchange server (the partner Exchange server) through which Cisco Unity communicates with the other Exchange servers. The partner Exchange server can either be the Cisco Unity server (when Exchange is installed on the Cisco Unity server) or a separate server.

For Exchange 2003, Cisco Unity can also service subscribers on both active/active and active/passive clusters. Do not install Cisco Unity on a server in an Exchange cluster.

All Subscriber Information Is Stored in a SQL Server 2000 Database

Cisco Unity stores all information about Cisco Unity subscribers, as well as selected Cisco Unity configuration data, in a SQL Server 2000 or Microsoft Data Engine 2000 (MSDE 2000) database on the Cisco Unity server. (The number of voice ports on the Cisco Unity server and, therefore, the maximum number of subscribers the server can support, determines whether data is stored in SQL Server 2000 or in MSDE, which is fully compatible with SQL Server 2000.)

When two or more Cisco Unity servers are in the same Domino domain and monitoring the same address book, or are in the same Active Directory forest, the SQL Server 2000 database on each Cisco Unity server also includes a small amount of information about all of the subscribers on the other Cisco Unity servers.

Storing subscriber data in a SQL Server 2000 database has the following benefits:

•Performance: Because the SQL Server 2000 database is on the Cisco Unity server itself and because the data is heavily indexed, accessing data—including looking up subscriber extensions—is fast. The current maximum number of Cisco Unity subscribers in a Domino address book or Active Directory Global Address List is 250,000.
